摘要：

针对二连盆地乌兰花凹陷安山岩储层的特性认识不清、有效储层划分不准确的问题，利用岩心薄片、黏土矿物分析、物性测试以及核磁共振实验等手段开展了岩石储集空间特征、岩石蚀变程度、测井响应特征分析。在此基础上，重点开展了基于核磁共振实验的安山岩储层有效孔隙度计算模型研究，开发了相适应的测井解释评价模块，并结合常规测井和试油结果建立了安山岩储层的分类标准。结果表明：安山岩储集空间具有发育"微孔"、"杏仁孔"双孔隙的特征，且以微孔为主；根据不同蚀变程度所建立的安山岩有效孔隙度计算模型具有很高的精度，平均绝对误差为0.16%，平均相对误差为19.40%；新测井解释储层分类标准在实际应用中与试油结论具有很好的一致性，有利于乌兰花凹陷安山岩有效储层的精确划分，并为该地区开发方案的设计及可采储量评价提供技术支持。

Abstract:

Aiming at the problems of unclear understanding of the characteristics of andesite reservoirs in Wulanhua sag, Erlian Basin and inaccurate classification of effective reservoirs, this paper analyzes the characteristics of reservoir spaces, rock alteration extents, and logging response characteristics by means of the thin sections of core samples, clay minerals, physical properties and nuclear magnetic resonance experiments. This study focuses on the calculation model of effective porosity of andesite reservoirs based on nuclear magnetic resonance experiments, develops a suitable logging interpreting evaluation module, and establishes the classification standard of andesite reservoirs based on the results of conventional logging and oil testing. The results show that the reservoir space of andesite has dual pore characteristics of developing "micropores" and "amygdales", and micropores are dominant. The calculation model of effective porosity of andesite established according to different alteration extents has high accuracy. The average absolute error is 0.16%, and the average relative error is 19.40%. The new classification standard of reservoir based on logging interpretation is in good agreement with the results of oil testing in applications, which is conducive to the precise classification of effective andesite reservoirs in Wulanhua sag, and provides technical support for the design of development program and the evaluation of recoverable reserves in this area.

Key words: Wulanhua sag, altered andesite, nuclear magnetic resonance, effective porosity, effective reservoir
