摘　　要：目的通过分析研究,厘清研究区长6储层油水分布特征。方法顺延砂体走向和垂直砂体走向分别制作两条油藏剖面图,通过对剖面图详细分析,得出目的层油水分布规律。结果研究区砂体呈条带状展布,纵向上层间非均质性较强,油层厚度较薄,厚度变化较快。结论研究区长6储层油水接触关系正常,但油水分异程度差,油水同层现象普遍,纯油层较少,差油层、油水同层较为发育,并且油水相变迅速,以连片层状或透镜体状为主。Purpose:Identify the oil-water distribution characteristics of the reservoir in this area by analysis and research.Methods:Follow the alignment of sand body and vertical sand body,and then make up two oil reservoir profile maps.By thorough analysis of the profile maps,draw a oil-water distribution rule of the target stratum.Result:Sand body in the target area distributes like ribbons.Besides,oil layer is thin and the thickness of it changes fast.Conclusion:Contact relation between oil and water of Chang 6 reservoir is normal in this area,whereas,differentiation of oil and water is bad.In addition,oil and water are usually in the same layer,thus,pure oil layer is rare.What's more,bad oil layer and oil-water layer are mature,meanwhile,oil and water facies switch rapidly.Most of the oil layers are slices-banding shaped or lens shaped.
