【摘要】 随着勘探程度的提高,裂缝型油气藏在新增储量中将会占有更大的比重。准确预测裂缝发育带是评价裂缝型储层的前提,对裂缝型油气藏的认识起着举足轻重的作用,亦是裂缝型油气藏提高勘探效率和开发水平的关键。在文献调研的基础上,研究了国内外关于储层裂缝预测研究的现状,分析论述了常规测井、成像测井法、地震预测方法及其他一些定性预测方法、构造应力分析法、曲率分析法及生产中应用的方法,提出构造应力法及曲率分析法是较为有效的裂缝预测方法;岩心及测井资料虽对裂缝的识别较为准确,但其控制点有限;要对整个油气田裂缝分布进行预测,需要以岩心及测井资料为约束,对地震资料进行刻度,以准确预测全区裂缝分布规律。更多还原

【Abstract】 As the improvement of exploratory level, fractured reservoirs will contribute more to newly increased reserves. Effective prediction of fractured belt is crucial in evaluation and understanding of fractured reservoirs and improvement of exploration efficiency and exploitation level. Based on literature investigation, this paper studies the present status of reservoir fracture prediction at home and abroad, analyzes and discusses methods of conventional logging, image logging, seismic prediction and other qualitative prediction, tectonic stress analysis, curvature analysis, and other practically applied methods. It is suggested that tectonic stress method and curvature analysis method are more effective in fracture prediction; although core and logging data are more reliable in identifying fractures, their control points are limited. To predict fracture distribution in whole oilfield, core and logging date shall be used as constraints to calibrate seismic data and give a precise prediction for the whole area.更多还原
