摘要

在系统梳理国内外致密油勘探生产与资源评价方法研究现状、总结中国石油第四次油气资源评价研究成果的基础上,归纳了适合于我国的致密油资源评价方法、工作流程,介绍了最新评价软件的结构、模块和功能,改进了小面元法,形成了GS预测技术,并根据各种评价方法在中国石油第四次油气资源评价中的使用情况,分析了评价软件的应用效果。应用实例展示该技术在鄂尔多斯盆地延长组长7段致密油资源分布预测中效果明显,预测出优质资源主要分布在姬塬的北部和南部、环县东部、长官庙南部、城壕西北部和东部以及塔儿湾等地区,为下一步勘探生产提供参考。

Abstract

Based on the analysis of the status of global exploration and production,and studies on resources assessment methods of tight oil,and the research results of the fourth round of petroleum resources assessment of PetroChina,this paper summarizes the methods and work flow of tight oil resources assessment suitable for China,and introduces the structure,modules and functions of the latest evaluation software system.The application of various assessment methods in the fourth round of petroleum resources assessment of PetroChina was studied,and the application effect of this assessment software system was analyzed.In this paper,the small bin method was improved,forming GS prediction technique.The application instance shows that this technique has apparent effect on tight oil resources distribution prediction in the 7th member of the Yanchang Formation in the Ordos Basin.According to the research results,the high-quality tight oil resources are mainly distributed in the following regions:North and south of Jiyuan area,east of Huanxian area,south of Changguanmiao area,northwest and east of Chenghao area,and Taerwan area,etc.The study results can provide useful reference for future tight oil exploration and production in this region.
