摘要
根据储层特征及保护油气层要求，选用以油溶性和酸溶性暂堵剂为主处理剂的超高密度改性钻井完井液体系。室内试验及新疆麦盖提地区现场应用表明，在超高压、高矿化度条件下，该体系对碳酸盐岩储层有显著的保护作用。
According to the reservoir features and the requirements of protecting reservoir,a modified drilling and completion fluid system with ultrahigh density is chosen,in which oil soluble and acid soluble temprary plugging agents are the major additives.It is suggested by lab tests and field applications in Maigaiti area,Xinjiang,that this system could remarkably protect the carbonate reservoir in the condition of overhigh pressure and high salinity.
