摘要
裂缝是地壳上最小的构造,成因复杂,控制和影响因素多样,形成和发育具有随机性,分布具有高度非均质性,因此储层裂缝的精细描述和预测仍是目前石油地质界的一个世界性难题,至今还没有一套很好的技术方法来根本性地解决储层裂缝分布问题.笔者通过对国内外学者研究成果的总结,简单介绍了当今裂缝识别、预测、参数定量表征等方面的研究进展,着重对比分形几何、曲率、古今应力场数值模拟等裂缝定量预测手段,分析其优点及限制条件,对相对先进的古今应力场数值模拟法进行详细介绍,指出其存在的问题和发展方向,可以作为今后裂缝研究的参考,为裂缝性油气田储层评价提供依据.
Crack is the smallest structure of the crust, complex causes, variety of control and influence factors, the randomness of the formation and development, high degree of heterogeneity of distribution, therefore, the fine reservoir description and prediction of crack is still a worldwide problem of the petroleum geology industry, so far does not have very good technical way to fundamentally solve the problem of reservoir fracture distribution. Through a summary of research scholars, briefly introduced the research progress of fracture identification, prediction, parameter quantitative characterization etc. , on the score fractal geometry, curvature, numerical simulation of ancient and modern stress field, analyze the advantages and limitations, to introduce the relatively advanced method of ancient and modern stress field numerical simulation, pointed out that the existing problems and development direction, which can be used as reference for future studies of crack and provide the basis for fractured reservoir evaluation of oil and gas field.
