A区块葡萄花油层油藏富集规律研究

Study on the Accumulation of Putaohua Reservoir in Block A

A区块葡萄花油层断层密度大、砂体厚度薄、油水关系复杂、油藏规模小,有利含油富集区优选难度大。通过开展井震结合精细构造解释识别小断层及微幅度构造;通过小时窗地震属性及高精度相控地震反演结合落实砂体展布范围;应用钻井、测井、录井及试油资料开展综合地质研究,明确成藏主控因素,落实含油富集区。

The Putaohua reservoir in Block A has a large fault density, a thin sand body and a complex oil-water relationship.The reservoir size is small and the favorable oil-rich area is more difficult to select.Identifying small faults and micro-amplitude structures by well-well combination with fine structure interpretation： Implementing sandbody distribution through combination of small-window seismic attributes and high-precision phase-controlled seismic inversion ; Applying drilling, well logging, logging and oil testing data Comprehensive geological research, a clear main controlling factors of accumulation, the implementation of oil-rich area.
