复杂断块油藏河31断块开发后期油藏描述及剩余油分布规律研究
|
摘要
以石油地质学,沉积岩石学,构造地质学为理论指导,充分吸收最新的理论和技术方法,对研究区的构造,储层,流体特征及油藏开发特征进行研究,利用计算机等先进手段对剩余油的分布进行定量描述,为油田开发下一步的措施提供地质依据,并总结出复杂断块油气田开发中后期剩余油分布的一般规律,形成剩余油定量表征的一套工作方法和工作流程。复杂断块油气田开发中后期,应在三维地震基础上结合钻井资料、测井资料,利用数值模拟等定量化描述手段,对油田开发中后期的剩余油分布作定量描述。
With the petroleum geology,sedimentary petrology,structural geology as theoretical guidance,the structure,fluid characteristic and reservoir development characteristics of the complex fault block oil reservoir He-31 block were studied.By using computer technology and other advanced means,the distribution of remaining oil was quantitatively described,the general laws of remaining oil distribution in middle-later development of complex fault block oil/gas field were summed up,and a set of working methods and working paths of remaining oil quantitative characterization were formed.In the middle-later development of complex fault block oil /gas field,in order to quantitatively depict remaining oil distribution,the numerical simulation and other quantitative description methods should be applied based on 3D seismic date,drilling and logging data.
