基于体曲率属性的缝洞型碳酸盐岩储层预测
|
摘要
冀中坳陷霸县凹陷文安斜坡发现和探明的古潜山油气藏储层为中上元古界和古生界碳酸盐岩,其储集空间以孔洞、裂缝为主,潜山内幕有效储层与致密层并存,非均质性强,物性横向变化较大,裂缝是影响储集性能的主导因素,因此裂缝预测对该区潜山油气藏的成藏条件分析起着至关重要的作用。探讨了应用体曲率属性对碳酸盐岩缝洞型储层进行研究的思路与方法,预测和刻画了储层缝洞体系的空间分布规律,划分了储层发育有利区带。研究结果为研究区油田生产提供了地质依据,同时也为类似地区的储层预测提供了重要的参考和借鉴。
The discovered and proved buried hill reservoirs of Baxian Sag in Jizhong Depression were Upper Proterozoic and Paleozoic Ordovician carbonate reservoirs,the reservoir space was mainly of caves and fissures.Within the buried hill the effective reservoirs and compacted layers were co-existent,where existed a strong heterogeneity and lateral variation in physical property.The fissures were the dominant factors influencing the reservoirs;therefore fractural prediction played a vital role for analyzing the accumulation conditions of the buried hill reservoirs in the area.This paper discusses the ideas and methods of application of volumetric curvature attribute in studying the carbonate fracture-vuggy reservoirs,the spatial distribution rules of fractured reservoir system are predict and depicted,the favorable reservoir development zones are identified.It provides a geological evidence for oilfield production,and it also provides important reference for reservoir prediction of the similar areas.
