微构造对油水运动规律的影响

A STUDY ON THE RELATIONSHIP BETWEEN THE MINI-STRUCTURE AND THE RULES OF THE FLUIDS MOVEMENT

对微构造的成因和分类进行了论述,并以张天渠油田为例,就各种微构造组合方式对油水运动规律的影响进行了说明,得出结论:正向微构造为油气富集区,负向微构造为低含油气或严重水淹区。在确定加密井井别时,应尽可能地把生产井钻在正向微构造区,把注水井钻在负向微构造区。

This paper briefly discusses the genesis mechanism and classification of the mini-structure.The distribution and mechanism of the remaining oil that the mini-structure caused are studied in the paper,and also effect that the types of mini-structure had brought about on the fluids movement rules as an example of the Zhangtianqu Oilfield.The conclusion is that the positive mini-structure is regions of oil and gas enrichment,the negative mini-structure is regions where severe water invasion occurs.In the designing of well locations,according to mini-structure,infill wells should be drilled on the positive mini-structure areas and only injection wells are drilled in the negative mini-structure areas.
