超低密压裂支撑剂的制备及性能研究
Preparation and Properties of Ultra-light Weight Fracturing Proppants
摘要
Abstract
Based on bauxite and a small amount of K-feldspar,ultra-light weight,high-strength fracturing proppants was prepared by adding the dolomite with different addiction.The influence of the addiction of dolomites on sintering temperature and properties of fracturing proppants was studied.The results show that a proper amount of K-feldspar can not only reduce the sintering temperature but also reduce the density of fracturing proppants.The addiction of dolomite can effectively reduce the sintering temperature and breakage ratio of proppants,while the dolomite and K-feldspar together to promote the formation of liquid phase,which is favorable to the growth of the rod-like mullite,thus the strength of proppants is improved.The proppants have a good performance with the bulk density and breakage ratio(under 52 MPa)of 1.30 g/cm3 and 4.51wt％apparently when the addiction of dolomite is 2wt％and the sintering temperature is 1330 ℃.关键词
