海拉尔探区钻井完井过程的油气层保护技术

Oil/gas layer protecting techniques in the course of drilling and completion in Hailaer exploration area

海拉尔盆地是保持大庆油田原油稳产的主要接替区。针对海拉尔探区的地质特点、储层特性和钻井完井过程中保护储层的技术难点, 对该区的油气层保护技术及其应用效果进行了详细的总结。结果表明, 实施油气层保护技术缩短了海拉尔探区的钻井周期, 能够及时发现和保护储层, 推动了该区的勘探进程。

Hailaer basin is the main replacing area for maintaining stable oil production in Daqing oilfield.Concerning the geological characteristics,reservoir feature and difficulties of reservoir protecting technique during drilling and completion in this exploration area,the protecting technique and its application effects are summarized in detail.The study results show that the utilization of reservoir protecting technique can reduce the drilling period and discover and protect petroleum reservoirs without delay,thus the exploration process of this area can be effectively advanced.
