Performance Oil proppant requirements

Performance Oil proppant requirements: 1 , proppant sufficient compressive strength and wear resistance , can withstand strong pressure and friction when injected , and effectively support the artificial cracks. 2 , the relative density of the  natural gas fracking  particles must be low, to facilitate pumped downhole . 3 , proppant particles under conditions of a temperature of 200 degrees , and the fracturing fluid and the reservoir fluid is not a chemical effect , the solubility of the acid should be less than the maximum allowable value of 7% . Currently used mainly quartz sand oil well fracking,bauxite sand and resin-coated ceramic composite particles. Due to the low cost of quartz sand , while lower density easy to pump , has been widely used , but quartz sand strong low end , the ball is poor, reducing the fracture conductivity , does not apply to high pressure deep well closed . Composite resin coated quartz sand particles , sphericity improved corrosion resistance strong, conductivity is also good , but the products remain short- term , the cost is too high, the cost of the promotion of the supremacy of today is not easy , and the use of bauxite ceramic craft ceramic natural gas fracturing, high density, good sphericity , corrosion resistance , high temperature, high pressure, while costs can be better controlled , and therefore more widely used in oil and gas fields being . Practice has proved that the use of ceramic proppant fracturing oil wells can increase production by 30-50% , but also to extend the service life of oil and gas wells , is the key material oil, gas wells in low permeability oil and gas exploration, construction , not only to increase oil and gas production , and more to extend the service life of oil and gas wells .

Select oil fracturing proppant

Oil fracturing proppant selection mainly includes the type, size and concentration. Select oil fracturing proppant and the pressure of the rock formations, environmental Maide proppant conductivity and yield requirements are closely linked. Should first consider when selecting Coal seam gas proppant nature and fracture flow capacity under certain geological, engineering conditions, combined with specific geological conditions (such as closure pressure, rock hardness, temperature, target layer properties) selected to meet the engineering conditions (fracturing fluid nature of pumping equipment), and can get a good yield results proppant. Second, you must also consider the economic benefits due to proppant variety, quality and origin conditions differences, there are differences proppant costs must be considered cost-effective, combining economics to analyze the preferred fracturing proppant.

Tap water burnable the phenomenon is caused shale gas

Tap water burnable the phenomenon is caused by hydraulic fracturing phenomenon. Hydraulic fracturing is to use a lot of mixed chemical water in hydraulic fracture to release gas shale formations. Hydraulic fracturing is the main form of exploitation of natural gas at lightweight proppant, the technology widely spread in the United States in a decade, but americans are worried about the technology will pollute the water, which endanger the local ecological environment and residents health. And that the technology has brought great harm to the environment, including water spontaneous combustion, triggered a small earthquake, etc.

When oil and shale gas exploration in deep

When oil and gas exploration in deep , high pressure low proppant manufacturing deposit closure after fracturing treatment, the rock cracked petroleum , oil and gas from the cracks in the channel formed by the pooled out. Along with a high-pressure high-alumina support material was filled into the formation in rock fissures , cracks do not play a supporting but closed due to stress release , thereby maintaining high conductivity , so that the oil and gas flow, increase production.

Shale gas use

Maide Shale gas revolution is a clean , efficient energy resources and chemical raw materials , mainly used for domestic and industrial fuels , chemicals and power generation and has broad prospects for development , the development and use of shale gas will help alleviate the shortage of oil and gas resources , increasing clean energy supply is an important supplement conventional energy sources .

Related to oil proppant

Oil fracturing proppant ( ceramic proppants ) is a ceramic particle product with high fracture strength , mainly for oilfield downhole support to increase production of oil and gas , an environmentally friendly product .
?
This product is the use of high-quality bauxite , coal and other raw materials, ceramic sintering , is a substitute for natural quartz sand , glass beads , metal balls and other low- strength proppant , to increase production of oil and gas has a positive effect .
?
 Practice has proved that the use of high-alumina fracturing proppant wells can increase production by 30-50% , but also to extend the service life of oil and gas wells , is the key material oil, gas wells in low permeability oil and gas exploration, construction . Products used in deep fracturing when it is filled to the low permeability fractured rock deposits in high closed fracturing treatment to split hydrocarbon formations , play a supporting fissure is closed not because of stress release , thereby maintaining oil and gas high flow capacity , not only to increase oil and gas production , and more to extend the service life of oil and gas wells .
