裂缝性潜山油藏储集层识别与预测

Identification and Prediction for the Fractured Buried Hill Oil Reservoir

埕北30太古宇为裂缝性潜山油藏,裂缝是其主要的储集空间和流体运移通道。裂缝性储集层识别与预测是这类油藏描述的核心和关键。为此,岩心、录井、测井、试井结合建立了储集层划分和分类标准,识别描述了井点储集层的分布;以井点储集层为约束条件,应用三维地震反演技术,预测了埕北30潜山太古宇油藏的储集层三维空间展布。

The Archaeozoic reservoir of Chengbei-30 is a fractured buried-hill oil pool.The fractures are major reservoir space and fluid course.The core and key in describing the fractured reservoir is to identify reservoir and predict their distribution.Thus,the standard for reservoir dividing and sorting is established combining with the data as core experimental analysis,logging,well log,well testing and geologic studying. This paper describes the reservoir distribution in wells and predicts 3-D reservoir distribution of Archaeozoic reservoir in the Chengbei-30 hurried hill with 3-D seismic inversion.
