埕海油田不同沉积储层砂体精细预测研究——以埕海一区庄海8断块为例
|
摘要
埕海油田地质条件复杂,沉积类型多,储层纵横向变化快,油藏类型复杂多样,储层精细预测难度大。针对储层预测的难题,使用多种技术手段来解决储层研究的多解性,如应用地震属性分析技术圈定有利储层范围,利用频谱成像技术提高储层空间横向识别能力,利用测井约束地震反演技术提高储层垂向分辨率,利用河道边缘检测技术,描述末期河道,通过综合应用各种技术的优点,从而实现对单砂体由点到面再到体的识别与追踪。
Fine reservoir prediction is difficult in Chenghai oilfield,which has complex geological conditions,multi sedimentary types,and diverse reservoirs with rapid changes in vertical and horizontal.For the problem of reservoir prediction,a variety of technical means is used to solve the multiple solutions of reservoir research,such as using seismic attribute analysis techniques to delineated the scope of favorable reservoir,spectral imaging technology to improve the horizontal recognition of the reservoir,logging constrained seismic inversion technology to improve the vertical resolution of reservoir,and river edge detection to describe the end of river.Through the integrated application of various technical advantages,we can achieve the identification and tracking of a single sand from the point to the plane then to the body.
