摘要
本文对微构造的定义、成因及分类进行了概述。并以张天渠油田长2油层为例,分析了不同类型的微构造对油田开发的影响。得出结论:位于正向微构造区的油井生产状况较好,位于负向微构造区的油井生产状况不理想。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,为油田下一步调整挖潜、完善注采井网服务。
This paper briefly discusses the genesis mechanism and classification of the micro-structure,and the relationships between the types of microstructures and the oilfield development of Chang 212 layer in Zhang tian qu Oilfield are studied. It is shown that,the positive micro-structure is regions of oil and gas enrichment, the negative micro-structure is regions where severe water invasion occurs. In the designing of well locations, according to micro-structure, infill wells should be drilled on the positive micro-structure areas and only injection wells are drilled in the negative micro-structure areas. This study work can provide the guidance for the further development of Zhang tian qu Oilfield .
