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 characteristics of reservoirs and the requirements of protecting oil and gas layers, the ultra-high density modified drilling and completion fluid system with oil-soluble and acid-soluble temporary plugging agent as the main treatment agent is selected. Laboratory tests and field application in the Maigaiti area of Xinjiang show that this system has a significant protective effect on carbonate reservoirs under conditions of ultra-high pressure and high salinity.
