岩性油气藏的储层预测及评价技术研究

针对岩性油气藏的储层预测及评价所面临的问题，提出了岩性油气藏的储层预测及评价技术思路和配套技术。其分4个层次：①基于层序地层学分析的小层对比、构造解释；②基于地震属性提取的岩性油气藏的定性识别技术；③基于地震波阻抗反演、拟测井参数反演的岩性油气藏定量(静态)评价技术；④基于多井拟测井参数反演的岩性油气藏定量(动态)评价技术。根据岩性油气藏的储层预测及评价技术，可以有目的地进行岩性地层油藏的勘探和开发。将岩性油气藏的储层预测和评价技术应用于准噶尔盆地石南31油田岩性油气藏勘探和大港周清庄岩性油气藏开发，获得了很好的应用效果。根据预测和评价结果部署的多口开发井不仅获得了高产油气流，且新井数据为油田的滚动开发提供了进一步储层预测及评价的依据。

Research on Technique of Predicting and Appraising Lithologic Deposit

It is presented that log layer interpretation and 3D seismic structure interpretation in terms of principle of sequence stratigraphy, which is important basis work; qualitative appraising technique of identifying lithological reservoir by seismic attribute; quantitative static appraising technique of Hthological reservoir by seismic impedance inversion and log parameters inversion; quantitative dynamic appraising technique of lithologlcal reservoir by log parameters inversion in many wells. According to technique of predicting and appraising lithology deposit, we can consciously make exploration and development of lithology deposit oilfield. Finally, this technique is successful in the exploration of SN31 lithology deposit oilfield and in the development of Zhou Qingzhuang lithological reservoir oilfield.
