摘要
三叠系延长组是长庆油田重要的油气储集层位,该套地层中存在启动压力现象。文中对该现象产生的原因作了初步探讨,认为启动压力的出现是多种因素综合作用的结果。同时以侯市地区的具体井位为例进行了分析测试。结果表明,侯市地区三叠系延长组地层存在明显的启动压力现象,且初步确定该地区启动压力梯度为0.327MPa/m。
The Triassic Yanchang Formation is an important reservoir in Changqing Oilfield, with obvious starting pressure phenomenon. After the discussion on the cause, it is believed that the phenomenon was resulted from multifactors. The analysis testing is carried out in Houshi area, and the result shows that the Triassic Yanehang Formation in Houshi area has obvious starting pressure, with a starting pressure gradient of 0.327 MPa/m.
