摘要
平湖油气田是一个受构造和岩性共同控制、边底水活跃的中型油气田,部分层位的油气水关系和接触关系比较复杂。其主要含油层花港组地层为陆相沉积,埋藏较深、连续性较差、岩性物性各向异性变化大,各小层的砂体平面分布、相互接触关系和物性分布规律还不太清楚。文章从精细构造解释、储层反演、物性随机模拟、地震频谱分解等工作入手对花港组地层的构造、储层特征、非均质性进行了精细研究和描述,取得了很好的效果,为该区的储量计算及油藏模拟工作奠定了基础。
Pinghu gas field is a middle-sized gas field controlled by the structure and lithology with active edge and bottom water,so the relationship among oil,gas and water in part of the layers and their contact relationship are more complex.The main oil-bearing formation in Huagang group is terrestrial deposit,which is buried deeply with poor continuity,heavy anisotropy in lithology and physical property.It is not clear that how the sand body planes in each small layer distribute and what the mutual contact relation and physical property regularities of distribution are.The paper describes the stratal structure,reservoir properties and heterogeneity in Huagang group from fine structural interpretation, reservoir inversion,stochastic simulation of physical property and seismic spectrum decomposition,etc.It has gained good result. It laid a foundation for reserves calculation and reservoir modeling in this area.
