Shale gas is generated

Shale gas is mined out from shale gas , shale or body located in dark carbon shale , the  maide Shale gas revolution is adsorbed on the body in order to exist in the free state or mudstone, carbon mudstone , shale and pink sandwich on sandy rocks in natural gas, which can be generated in various stages of organic origin of natural gas subject to the free phase ( about 50% ) present in the cracks , porosity and other reservoir space to adsorption state ( about 50% ) present in kerogen , clay particles and pore surface , a very small amount is stored in a dissolved state kerogen , asphaltenes and petroleum . Natural gas is also present in siltstone , silty mudstone , muddy siltstone sandwich -like , or even sandstone formations . After the gas generated in the source rock gathered nearby , the performance of a typical
Shale gas
Situ accumulation mode and differential oil shale, oil sands, bitumen and other large . Different from conventional reservoirs and gas reservoirs , maide gas fracking  generated by both the source rock is gathered and stored gas reservoir and cap rock . Therefore , the high organic content of black shale , mudstone carbon is often the best conditions for the development of shale gas .
Shale gas development has extensive geological significance , present in almost all of the basin , just because burial depth , gas saturation and other big difference with different industrial value , respectively . Fractured shale gas Chinese traditional sense , shale oil and gas reservoirs , fractured shale reservoirs , fractured reservoirs , etc. This is quite roughly , but did not consider the mechanism of adsorption is not considered one of the primary attributes of natural gas and understanding of the body is gathered in the cracks in the shale oil and gas in free phase . Shale gas is not complete and therefore belongs sense. Therefore , China 's fractured shale reservoirs concept and connotation of shale gas in the United States today are not the same , namely, the material content of hydrocarbons , storage phase , there is a big difference between the source characteristics and chemical composition and other aspects .

Well sand fracturing sand blocking factors

Sand plug is the most direct cause of the failure of fracturing , especially tight clastic gas reservoir maide fracturing sand in the Sichuan region , the higher the chance of blocking sand , sand blocking factors affecting and more complex , including the formation factors, the fracturing fluid factors , engineering factors , design factors , how to effectively prevent sand blocking the generation of design and construction has been a fracturing operation was tricky puzzles . For large tower farm wells constructed TX-7 complex engineering geological characteristics and sand blocking characteristics, according to the results of the test and the main fracturing fracturing and curve data analysis and processing , analysis and evaluation of multiple fractures of the wells produce sand blocking the wellbore and the effects of different levels of near wellbore friction ,maide oil well fracking fluid efficiency and other factors, and for a large stretch of sand tower field structure for the ultra-low permeability reservoirs interbedded thin , high near wellbore friction , fluid loss coefficient and other complex geological and engineering features , proposed preferred perforation intervals , slug down friction , silt temporary blocking , filtering and other recommendations viscous liquid down a number of important technical measures , the conclusions and recommendations of the Sichuan region of dense gas reservoir rocks the fracturing of important guiding significance.

Mechanism of oil and gas wells and sand hazards

From the rock mechanics point of view, there are two mechanisms reservoir sand : the shear failure and tensile failure mechanism . In addition to these two mechanisms , but also includes a maide Coal seam gas particle migration mechanism .Shear failure mechanism . As the rock near the wellbore and perforations suffered circumferential stress and radial stress is too large , causing the rock shear failure , causing formation sand .Tensile failure mechanism . When mined , the friction stress around the maide frac proppant fluid gradient and under the action of carrying rocks to withstand tensile stress when this stress exceeds the tensile strength of the rock, the rock tensile failure .Sand particle transport mechanism . In production, the production of pressure or excessive production , acting on the formation of particles too large to pull the drag force , will move particulate formation , leading to decreased formation permeability around the bottom , thus increasing the drag of the fluid drag force , and solid particles may induce output .Sand hazards mainly in the following areas: reduction or stoppage, abrasive surface and downhole equipment , casing damaged wells scrapped , lost production time, the economic and technical losses such as oil and gas wells .

Fracturing sand tank truck drivers beware stuffed in a car accident driving interference

Driving interference potential hazards : No turning the turn ; parking the car in front suddenly turn left and you did not have time to react , pulled out of the driveway ...... attention due to the fracturing of normal car driver Shaguan disturbance arising from lack of concentration , is becoming important reason for the accident .
The so-called driving interference is caused by anything fracturing Shaguan car driver's eyes, hands or attention away from the driving task , such as watching outside the square , tune radio channels , pay attention to the car 's children , phone calls, talking with passengers , eating things , look at the map , etc. All these activities will result in fracturing sand tank truck driver distracted and dangerous accident .
Fracturing resin coated frac sand tank car manufacturers Security reminder: To achieve safe driving , be sure to observe the three security elements .
One eye focused way. Think well before departure or planned route ; If you have a cell phone , try to use voice or abbreviated dialing ; do not take notes while driving , do not look up phone numbers .
Second, keep your hands off the steering wheel . Before departure familiar fracturing Shaguan car equipment functions ; pre- tuned radio and air conditioning ; may be fixed traffic moving objects ; while driving if items dropped on the floor , do not pick up, such as when a parked car and then picking it not later ; teach children to develop good riding habits, pick up the child , smoothly pulled out of traffic to pull over ; avoid smoking , eating , drinking while driving ; do not answer the phone while driving , using a mobile phone message function , and so drove safety zone and park before playing back.
Third, concentrate on driving . If you find that lack of energy , a little rest and then hit the road when driving ; let passengers in the car to help " find a way ." Do yourself while driving view maps and navigation systems ; Do not use the phone while driving with passengers or unpleasant conversation , when using the phone's handsfree function , it tends to distract yourself .

Fracturing sand tank car red light when Mo variable line

Maide fracturing sand tank truck drivers to drive will encounter this situation , on the road , I noticed a red light in front of your own driveway has a car parked in that , while the lane next to no cars parked there , in order to be able to change the green light when hurry away, in this case I believe most will choose to change from their driveway onto the lane without a car , but that such a move you're illegal , and illegal reasons: compaction line.
Is the intersection between the solid line dividing lanes open, while we learn traffic rules when driving do not go compaction line should be the most impressive , but at certain moments such as the above said case or to go to work during the peak period , see which lanes empty lanes wanted where to go , the result of compaction line, you say this ticket that you eat at a loss .
For the red line becomes the practice of fracturing sand tank car is not only a violation of the intersection , etc. , or dangerous if you change the lane to the rear of a sudden a car drove up is likely to hit you , that if you touch someone looking porcelain child , you one hundred fair hearing , compaction line violation, the full responsibility .
Fracturing sand tank car Reminder: Ning -thirds undisputed second, for that early out for a few seconds that you bear such a big risk not worth when the

Hydraulic fracturing of shale gas wells

Because shale gas reservoirs display physical characteristics of low porosity and low permeability , so only a handful of naturally fractured Maide Coal seam gas development in particular can be directly put into production, but most of the shale gas wells after hydraulic fracturing fluid needs to get ideal production. Shale gas wells after hydraulic fracturing , the use of fracture monitoring technology can effectively evaluate the fracturing effect.
Monitoring through the cracks :
a) a better understanding of fracturing , get roughly the size of the cracks to determine whether or not a multi- fracturing cracks ;
b) After extracting yield better situation to determine whether to overwrite the target layer cracks , fractures and natural fractures analyze whether the cross ;
c) fracturing optimization and yield economic evaluation, fracture length and height growth with increasing number of construction scale can be obtained , for optimal fracture design .
So take an accurate understanding of fracture monitoring method is an effective means of expanding shale gas well fracturing .
