高阳地区下第三系油藏描述与评价
|
摘要
薄层砂体横向预测是油藏描述的关键性技术环节，运用地质、测井约束条件下的地震综合反演技术，提高了波阻抗剖面的分辨率和砂岩储层物性参数的预测精度，对高阳三维地震区下第三系薄层砂岩储集岩系进行了以构造解释和储层预测为主要内容的油藏描述与评价，综合分析并初步预测了该区下第三系油藏的圈闭类型、富集规律及其有利勘探方向。
Thin layer sandstone prediction is the key problem in reservior description.In this paper,the structure,physical parameters,lateral variation of a reservoir could be accurately predicted by the technology of comprehensive constrained seismic inversion.This method improved the resolution of the impedance profile and the reservoir prediction.This method was used in the reservoir description and assessment of Eogene thin layer sandstone reservoirs in Gaoyang Region and was proved to be effective.The reservoir trap types,accumulation regularities as well as exploration targets in the area were predicted.
