探明中原油田东濮凹陷深层气储量相当丰富,但勘探开发工作一直没有取得新的突破。为找到后继资源,濮深15井在改进钻井液工艺的基础上采用屏蔽暂堵型钻井液体系保护储层。结果表明,储层平均渗透率恢复值为90.2％,损害半径小,表皮系数仅为0.073,屏蔽暂堵型钻井液在濮深15井应用达到了保护储层的目的。
It is proved that deep gas reserves in Dongpu Depression of Zhongyuan Oilfield are quite abundant, but no new breakthrough has been made in exploration and development work. In order to find the successor resources, Pu-Shen-15 well protected the reservoir by using the temporary shield plugging drilling fluid based on the improvement of drilling fluid technology. The results show that the recovery value of reservoir average permeability is 90.2%, the damage radius is small and the skin coefficient is only 0.073. The application of shield temporary plugging drilling fluid in Pu-Shen-15 well achieves the goal of reservoir protection.
