Development of oil fracturing proppant method

Fracturing technology for oil and gas exploration plays a very important role, while oil   fracturing proppant   fracturing technology is the ability to obtain oil key to success. Oil fracturing proppant, is to make deep geological formations rock fractures remain split state supports. In the development and use of the process, the fracturing proppant fracturing fluid mixed with the use of coercion injected deep cracks in the rock strata support in order to improve oil derivative, increase oil production.
 
At present, the domestic development after the adoption of  ceramic proppant  fracturing strength is generally low, only for shallow wells mined. If these  Fracturing proppant  used in deep wells, will bear great pressure and rock formations in a variety of corrosive environments, will be a substantial crushing, crushing 20 to 40 mesh 69MPa rate is generally between 4% -8%, it is difficult to meet the wells requirements.
 
Internationally (such as the U.S.) developed sintered corundum products after use more, but although the physical and chemical properties of this product meet the requirements on, but difficult to sources of raw materials, processing complex, and energy consumption, and high cost.
 
Nations on the  Proppant  reported less developed areas to native alum produced proppant material as the main raw material of development, has not been reported. We use Panzhihua Ertan bauxite resources, innovative materials and native alum proposed for the production of clinker, the main raw material proppant, together with special accessories, through laboratory small scale, the resulting high-strength low broken rate pressure crack proppant achieve the desired purpose.
