胡状集油田位于东濮凹陷西部斜坡带。该油田非均质性严重，在注水开发过程中，储层参数发生变化，油水井间形成优势渗流通道，加剧了层内、层间矛盾。文章从油藏沉积环境、岩性特征及脱胶结作用等地质特征方面入手，分析了优势渗流通道的形成机制和分布规律；结合油田开发动态，分析了注水开发前后优势渗流通道对油水井开发的影响，提出了相应的开发对策。

Huzhuangji Oilfield is located at the west slope belt of Dongpu Depression and is very heterogeneous. During the development of water injection, reservoir parameters changed greatly, and advantage percolating channel has been formed between the wells of production and injection, which makes the contradictions within or between formations intensified. This paper analyzes the forming mechanism and distributing regulation of the advantage percolating channels according to the geologic characteristic of the depositional environment, lithological characteristic and decementation etc. Combined with the dynamic state of the development,
the paper also analyzed the influence of the advantage percolating channels to the oilfield development before and after water flooding. And corresponding plan is put forward for the further development.
