Abstract
Light-weight middle-strength ceramisite proppant is beneficial to the improvement of productivity of low-permeability oil and gas reservoir,and is able to reduce the cost of oil and gas production significantly.The light-weight middle-strength ceramisite proppant was prepared from bauxite(63 wt% Al2O3) by adding manganese mineral,part of that was replace by iron powder.The results show that strength of ceramisite proppant was improved by rod-like mullite with the diameter of 0.3 ~ 1.0μm,which playa remarkable role in the increment of fracture toughness,when iron powder content is 3 wt%,and manganese mineral content is 2 wt%,and dolomite content is 1 wt% and sintering at 1 350 ℃ for 1 h.The breakage ratio is 5.29% and bulk density was 1.63 g/cm3 under 52 MPa closure pressure.In addition,as the iron powder increase,he liquid phase increase in the matrix,many intergranular closed pores were formed as a result of the grain growth which was too speedy to eliminate pores.It is easy to form the crack source and reduce the density and strength of ceramisite proppant.关键词
