摘　　要：随着油气田勘探开发的深入,地质专家对探区地质认识水平的不断提高和难采储量的动用,低孔、低渗油气藏有效开发逐渐成为石油地质工作者攻关的重要课题之一。镇泾油田属于低孔、低渗油藏,统计分析各项录井数据中对低孔、低渗油藏敏感的参数,并把描述性的录井资料数字化,根据每一项资料所起作用的大小赋予不同的权重,得出每一项参数分量,各分量之和即为地质综合评价参数,进而将地质综合评价参数和测试产油量进行拟合,则可形成现场利用常规地质录井参数快速评价低孔、低渗油藏的方法。在此基础上引入测井相关参数,通过对储集层物性和含油丰度与录、测井参数相关性的综合研究,结合试油测试结果,建立录、测井油气水层综合解释评价图板,形成了现场半定量化快速综合评价方法。应用实践表明,该方法准确可靠,解决了低孔、低渗油藏储集层解释评价难的问题,对于其他油田同类油气水层评价也具有借鉴作用。With oil and gas field exploring and developing in deep,the ge- ological acreage recognition level of geologic experts continuously deepening,unrecoverable reserves' producing,the efficient develop- ment of hydrocarbon reservoir with low porosity-low permeability, has gradually become one of important research topics for oil geolo- gist.Zhenjing Oilfield belongs to low porosity & low permeability reservoir,the parameters from various mud logging data,which are sensitive to low porosity & low permeability reservoir,were made for statistical analysis,the description for mud logging data were digitized,each data,according to its function,big or small,is as- signed a right weight and a parametric component.The sum of each component is geologic comprehensive evaluation parameter,and then through matching the geologic comprehensive evaluation pa- rameter with test oil produetion,a quick evaluation method for low porosity & low permeability reservoir can be formed with use of conventionai geologging data.Based on this,the mud logging and wireline logging water-oil-gas comprehensive interpretation & eval- uation chart was set up by using wireline logging correlation param- eter,through making comprehensive correlatability studies between reservoir physical properties and oil bearing richness and geologging and wireline logging parameter,and combining with oil testing re- sults,therefore forming on—site semi-quantitative quick compre- hensive evaluation method.This method is accurate and reliable, solves the difficult interpretation & evaluation problem for hydro- carbon reservoir,and can be used as reference for the other oilfields to evaluate the same type of water-oil-gas layers.
