Fracturing proppant is a kind of ceramic particle product, has the very high fracturing strength

Fracturing proppant is a kind of ceramic particle product, has the very high fracturing frac sand, mainly used for oilfield downhole support, in order to increase the output of oil and gas, environmental protection products. This product use high quality bauxite and other raw materials, ceramic sintering and become, is a natural quartz sand, glass balls, metal balls substitute for middle and lower strength proppant, to produce more oil and gas has a good effect. Oil and natural gas deep well drilling, high closure pressure and low permeability ore deposit after fracturing treatment, split oil and gas layers, oil and gas from collecting in the crack formation of the channel. With ceramsite support material with high pressure solution into the strata filling in rock fractures, supporting crack because of the action of stress release and closed, so as to maintain a high diversion ability, make the oil and gas flow, increase production. Practice has proved that using ceramsite proppant fracturing of oil Wells can improve the production of 30-50%, still can prolong oil and gas well service life

Fracturing proppant can be widely used in deep well, high pressure oil and gas layer fracturing. By the high quality bauxite as main raw materials made of fine ground into powder, match with various additives, fracturing proppant practice, granulating, polishing, high temperature sintering, the product has high crushing strength, low density, good sphericity, high smoothness, diversion ability, etc. Supported by the oil exploration and development research institute of China langfang branch evaluation laboratory tests, each performance index of SY/T5108-2006 completely, / T6302-1997 standards, is at a leading level hydraulic fracturing (hydrofracturing method), also known as hydraulic fracturing method. An absolute stress measuring method. When measuring the first take a bedrock exposed drilling, sealed on both ends up and down with the packer, Pressure and injection liquid, until hole wall burst, and record the pressure changes over time, and using the mold or downhole television observation fracture azimuth. According to the record of pump pressure and the fracture azimuth, fracture pressure and close using the corresponding formula to calculate the stress size and direction of the landlord.
