摘要

摘要: 我国中西部地区前陆盆地山前逆冲构造带挤压应力异常强烈.强烈的构造应力不仅改变了储层的性质, 而且还直接控制着油气的聚集和分布.研究发现, 泥岩对地应力的响应十分灵敏, 通过泥岩的测井响应可建立对地应力进行定量评价的方法, 计算结果与实验结果进行了对比, 表明该方法具有较好的可靠性.在对单井地应力分析的基础上, 确定了地应力的分布, 研究了地应力对储层物性的影响, 并分析了地应力与构造样式的关系, 为前陆盆地山前构造带的油气勘探与评价提供了新的思路与方法.

Abstract: Compressive tectonic stress is extremely strong in the piedmont thrust belt of the median-west of China. The strong tectonic stress not only changes the reservoir properties but also directly controls hydrocarbon accumulation and distribution. The characteristics of shale, particularly shale resistance, can easily reflect the state of terrestrial stress. This characteristic can be used to evaluate the stress quantitatively, which was proved to be reliable by a comparison of the data from an acoustic emission experiment. Based on the in-situ stress analysis of many wells, in-situ stress distribution has been determined. The effect of terrestrial stress on reservoir property was studied and the relation of local terrestrial stress with structural styles was analyzed.Resultsshow that the high-quality reservoir always coincides with relatively low terrestrial stress belts.
