Performance agent support structure

Proppant to have a certain size and natural gas fracturing of the natural sand or synthetic high-strength ceramic particles. Ceramic proppant (ceramic proppant) to bauxite as raw material by powder granulation, sintering, high temperature, high pressure, corrosion resistance, high strength, high conductivity, low density, low breakage rate, etc. , the most widely used. In the resin-coated sand or ceramic surface, Hydraulic Fracturing Proppants is possible to further improve the strength and conductivity properties of the proppant. Proppant and supported by the fracturing fluid into the formation of cracks in the fracture, thereby effectively imported oil and gas wells, a substantial increase oil and gas production and extend well life.

Oil fracturing proppant knowledge introduction

Ceramic proppant acid fracturing of oil is a product of ceramic particles with high fracture strength, mainly for the oil well supported, to increase production of oil and natural gas, an environmentally friendly product. This product is the use of high-quality bauxite and other raw materials, sintered ceramic, 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. When oil and gas exploration in deep, high pressure low permeability Deposits closed after fracturing treatment, the rock cracked hydrocarbon, oil and gas from the channel formed by the collection out of the cracks. Ceramic support material along with high-pressure solution is filled into the formation in rock fissures, cracks do not play a supporting closed due to stress release effect, thereby maintaining high conductivity, so that oil and gas flow, increase production. Practice has proved that the use of ceramic proppant fracturing wells can increase production by 30-50%, but also to extend the service life of oil and gas wells.
Uses: ceramic proppant fracturing of oil can be used in fracturing fluid deep, high-pressure oil and gas layers. High quality bauxite, the raw material for the king to be finely ground into a fine powder after crushing, with various additives, repeatedly kneading, granulation, polishing. Sintered at high temperature, the product has high strength, low density, good sphericity, finish high conductivity and strong advantages. My company's products by China Petroleum Exploration and Development Research Institute, Langfang Branch support evaluation laboratory testing, the performance indicators fully meet SY / T5108-2006, SY / T6302-1997 standard, currently in the lead.
Product Category:
1, according to the anti-fragmentation were 52MPa (7500psi), 69MPa (1000psi) and 86MPa (12500psi), 102MPa (15000psi) four series.
2, divided by the bulk density: low-density, medium density, high density.
3, according to the specifications are as follows: 12-20 mesh, 16-20 mesh, 16-30 mesh, 20-40 mesh, 30-50 mesh, 40-60 mesh, 40-70 mesh, 70-100 mesh and so on.
To meet the needs of domestic and international oil and gas wells, deep wells user can choose different intensity and different specifications

Shale gas production capacity exceeded 700 million cubic meters

Last year, Chongqing MaiDe Shale gas revolution capacity has exceeded 700 million cubic meters of shale gas development became the main battlefield of the National Energy Board and was identified as a national demonstration area of shale gas. This year, Chongqing will shale gas exploration and development in a more important position. Recoverable resources of approximately 2 trillion cubic meters, the country's third. 13-year national demonstration Fuling District of Chongqing petrochemical goods accumulated nearly 73 million cubic meters of gas.

Advantages of ceramic proppant

Because of quartz sand and sand-based proppants with practicality and low cost, they become the most popular maide natural gas fracturing proppant. However, studies on the recovery of the Society of Petroleum Engineers released in a show that has a higher strength and uniform size and shape than other types of ceramic proppant proppant can offer higher yields (SPE 77675). For different types of oil and gas reservoir conditions, the use of CARBO's ceramic proppant for fracturing oil and gas wells have maide natural gas fracking been able to maintain a good yield.

Preparation of oil shale residue proppant

Preparation of oil shale residue proppant research hydraulic fracturing technology is an efficient technology of oil field production. The process is to use the high pressure pump group on the ground, the high viscosity of fracturing fluid to greatly exceed resin coated frac sand displacement of the absorptive capacity is injected into the borehole, at the bottom to suppress high pressure; When the pressure is greater than the wall near the formation stress and formation rock tensile strength, near the bottom of the formation of cracks; Continue to inject with natural gas fracturing sand fluid, crack extension forward and is filled with fracturing proppant, shut-in after fracture closure on the filling of proppant, finally have emerged near the bottom hole formation has certain geometry dimension and flow conductivity of fracture, is advantageous for the crude oil around faster into the bottom of the well, achieve the goal of production. Hydraulic fracturing proppant as the important filling medium, its performance directly affects the whole well production capacity. So, the research of high performance oil proppant for oilfield production is very necessary. Oil fracturing proppant * main points of natural quartz sand, artificial ceramsite proppant, resin coated proppant (i.e., resin coated proppant) three categories, the effect of coated sand and resin coated ceramsite proppant and points two kinds. Natural quartz sand because of the sphericity is bad, low intensity, but the lowest cost, so generally used in great quantities in the shallow well; Artificial ceramsite proppant due to its good sphericity, high strength, corrosion resistance is strong, as well as good conductivity, by a large number of used for medium and deep well fracturing..
