胜利油区埕北30潜山储集性裂缝预测方法

PREDICTION METHOD OF RESERVOIR FRACTURES IN THE CHENGBEI 30 BURIED HILL OF SHENGLI OILFIELD

古潜山油藏的岩性复杂 ,又经历过风化淋滤和多次构造运动 ,因此它的储集空间的识别和评价一直是有待攻克的地质难题 ,尤其是古潜山裂缝性储层的评价更困难。作者以埕北 30古潜山的下古生界碳酸盐岩和太古界片麻岩储层为研究对象 ,通过定量化的岩心描述、实验室分析、测井分析、地震的相关分析及速度分析等方法进行综合研究 ,创造性地提出了一套潜山裂缝性储层的评价和预测方法。

As fossil buried hill reservoirs have complex lithology and have experienced weathering and leaching as well as multiple tectonism, the identification and evaluation of their housing space is always a geological puzzle to be overcome. The evaluation of fossil buried hill fracture reservoirs is especially difficult. Taking the Lower Paleozoic carbonate rocks and the Archaeozoic gneiss reservoirs in the Chengbei 30 Fossil Buried hill as objects of study, the authors presented creatively a set of evaluation and prediction methods for buried hill fracture reservoirs through comprehensive study by means of the quantitative core description, the laboratory analysis, the logging analysis, the seismic correlation analysis and velocity analysis, etc. These methods have directive significance for the study of the same kinds of reservoirs.
