复杂断块油田滚动开发技术研究
Because some complex fault-blocks found in Zhongyuan Oilfield during progressive exploration in recent years aren't known fully,it brings some difficulties for waterflooding development.
近年来,中原油田在滚动勘探中发现了一些复杂小断块,由于开发初期构造认识程度低,给注采完善工作带来了一定困难。
During the course of logging on site in Jie Faulted Block 2 in Yingzijie Area,due to various reasons,the values of TOC and abnormal multiple re- corded by gas logging are lower and there exits great deference between the result interpreted on site and the result by comprehensive interpretation in the later.
气测录井是钻井过程中发现油气层的重要手段,营子街地区街2断块现场录井过程中,由于各种原因的影响,导致气测录井录取的全烃值及异常倍数偏低,现场解释结果和后期综合解释结果出入较大;通过对各种影响因素综合分析后认为:导致该区目的层段气测值偏低的主要原因是沙三上段目的层的低孔低渗储层加上钻井液密度偏大,粘度过高影响及钻速较慢等因素的影响,对此采取相应的恢复手段,取得了较好的效果。

Through the research on the reservoir-forming conditions of complex fault-block oil reservoirs in Jizhong Depression, the results show that its reservoir-forming condition is relatively good.
冀中坳陷复杂断块油藏形成条件的研究结果表明,该油藏成藏条件优越,其构造背景、断层的封堵性、成油组合、砂体类型等是控制成藏的主要因素,并具有背斜型、斜坡型、断阶型等成藏模式,每一种成藏模式的控藏要素、富集程度及油藏分布差异较大,是复杂断块油气勘探中值得关注的主要问题。
