柴达木盆地油砂山油田油砂体分布及其控制因素

Distribution and Controlling Factors of Oil Sand Bodies of Youshashan Oilfield in Qaidam Basin

柴达木盆地油砂山油田为一典型的复杂断块油藏,该类油藏构造复杂、油砂体分布零散,开发难度较大。鉴于此,综合利用地质、测井以及开发动态资料,开展了油砂体分布及其控制因素等研究。研究成果不仅对该油藏今后注采完善、提高区块的水驱动用具有重要的实际意义,而且为同类油藏的勘探开发提供了相应的参考和借鉴。

Youshashan oilfield is a typical complex fault block reservoir; this kind of reservoirs have a lot of characteristics, such as complex structure, loosely scattered oil sand bodies, and difficulty in developing fault block reservoir. In this paper, based on geology, logging and developing dynamic data, distribution and controlling factors of oil sand bodies were synthetically studied. The research results not only have an important practical significance for future perfection of injection-production of the reservoir and improving waterflooding production of blocks, but also provide corresponding reference for exploration and development of the same type of reservoirs.
