摘　　要：碎屑岩储集层的非均质性研究是油田勘探和开发阶段的一项重要工作。利用综合测井资料研究了CH油田长6油层组储集层的岩性、物性、含油性等的非均质性,认为利用测井资料定量化地研究储采层的非均质性是一种行之有效的方法。分析了非均质性和产能之间的关系:岩性与产能——粒度粗、砂体均质和后生成岩作用弱,产能高,而粒度细、非均质性强烈和连通性差,产能低;物性与产能——油层内孔隙度大、渗透率高和非均质性弱,产能高,而孔隙度小、渗透率低和非均质性强,产能低。认为通过对油田非均质性的研究可以有效地预测油气藏和指导油气田开发,通过对非均质性研究和生产动态资料相结合并分析二者之间的关系,还可以发现,油气田非均质性是影响油气产能的主要因素。The study for the non-uniform feature of oil/gas reservoirs is necessary in the exploration and exploitation of oil field. This paper uses comprehensive logging information to research the lithological, geophysical and oil-bearing non-uniform feature of the Chang-6 oil layer in CH oil field. By detail interpretation to logging information, multidisciplinary analysis and calculation. Conclusion: the non-uniform feature of the Chang-6 oil layer is varied. Result: studying relation between the non-uniform feature and dynamic production considers that the non-uniform feature of oil/gas reservoirs is key effect factor in oil production.
