摘要
马井气田蓬莱镇组(J3p)气藏为低致密砂岩气藏,其储层具极强的非均质性,对该气藏的勘探如何入手,储层如何识别,这是一直在探索的难题。针对这类特殊的低致密砂岩储层,探讨了含气储层判识的方法,提取了不同含气级别的测井标志和地震识别标志,大大提高了判识储层品位的能力,有效地解决了对该气藏识别的问题,该技术对进一步评价和开发该气藏提供了技术保证。
Abstract
The gas reservoir of Penglaizhengmember(J3p) is a low tight sandstone reservoir with strong heterogeneity. How to distinguish such a gas reservoir has been a puzzling question for a long time. In this paper, the author discussed amethod designed for identification of such low tight sandstone reservoirs. By extracting features from logging and seismic data for gas reservoirs of different sizes, themethod can effectively recognize this kind of gas reservoirs. Themethod provides a basis for further assessment and development of this kind of gas reservoirs.
