【摘要】 致密碎屑岩裂缝性油气藏储量在低渗透储层总储量中占很大比例。致密碎屑岩裂缝性储层成为油气勘探开发研究的重要对象。当前,致密碎屑岩裂缝性油气藏勘探开发的最大难点在于如何对储层裂缝的发育程度和分布范围进行预测。准确进行裂缝预测对致密碎屑岩裂缝性储层的油气开发具有重要意义。本文对致密碎屑岩裂缝预测的方法进行了系统分析,从地质分析法、曲率法及构造应力场模拟、地震裂缝识别技术、测井裂缝识别技术和生产动态分析法5个方面对当前致密碎屑岩裂缝预测的主要研究方法现状进行了详细阐述,简要描述了各种方法的优缺点和应用条件;结合当前科学技术总体进展,指出致密碎屑岩裂缝预测研究的两个方面的发展趋势:单一的裂缝预测技术需要不断创新、综合多种方法各自的优势进行系统预测。更多还原

【Abstract】 Engineering practice shows that reserves of tight fractured reservoirs of clastic rock account for a large proportion of the total reserves of low permeability reservoirs.Their researches are important for exploration and development of oil and gas.An important difficulty in exploration and development of tight fractured reservoirs of clastic rock is how to accurately predict the growth degree and distribution range of reservoir fractures.In this paper,the methods of fracture prediction for tight reservoirs of clastic rock are systematically reviewed,including geological analysis,curvature method and tectonic stress simulation,seismic fracture identification technique,log fracture identification technique and production performance analysis.It is pointed out that there are two development trends for macroscopic fracture predictions of tight reservoirs of clastic rock:the innovation in the single methods of fracture prediction and the systematical engineering method integrating advantages of different single methods for fracture prediction.更多还原
