摘要
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。
Drilling fluid system with the function of temporary shielding plugging is applied in well Pushen-15, for formation protection and locating more oil/gas reservoir in this block. The drilling fluid design, its formulation, and field maintenance and treatment are described in this paper. The use of this system in well Pushen-15 is successful, and the average return permeability reaches 90. 2%, and skin factor as low as 0. 073.
