摘　　要：2021年以来,南海东部海域勘探开发重心转移,古潜山、深层低孔渗透储层逐渐成为探勘工作的转战场,固井面临压裂井高压低渗、防气窜及水泥石增韧等诸多难点与挑战。本文研究了一种韧弹性水泥浆体系多次成功应用于南海东部压裂井。Since 2021,the focus of exploration and development in the eastern part of the South China Sea has shifted,and buried hills and deep low-porosity permeability reservoirs have gradually become the battlefield of exploration.Cementing faces many difficulties and challenges,such as high pressure and low permeability of fractured Wells,gas breakthrough prevention and cement toughening.This paper studies a tough elasticity cement slurry system,which has been successfully applied to fracturing wells in the eastern South China Sea.
