Fracturing technology for worldwide oil production plays a very important role, but oil is a key oil fracturing proppant fracturing technology can be successful . High quality proppant can play an important role for the exploitation of crude oil. Oil fracturing proppant , is to keep the fractured rock formations deep split state support , particle size 0.2-0.9 mm, there is a certain roundness and sphericity . During use , the proppant Maide hydraulic fracturing fluid mixing , using coercion injected deep cracks in the rock strata support to improve the conductivity of oil , increased crude oil production .
At present , many domestic use fracturing ceramic, quartz sand , but their strength is low , only for shallow wells with . If these proppant use in deep well , will bear great pressure and rock formations in a variety of corrosive environments , will be a substantial crushing, crushing rate is generally 15% -25 % , but prevents the outflow of oil , it is difficult to meet the wells requirements. International ( such as the U.S. ) to use more sintered corundum products , but to meet the requirements of this article although the physical and chemical properties , but the sources of raw materials difficult , complicated process , and energy consumption, and high cost .
