致密砂岩裂缝储层形成的复杂油气藏,已经成为国内外油气勘探开发的焦点,常规勘探理论和方法在裂缝型油气藏评价中面临许多挑战,本文从砂泥岩裂缝型油气藏储层评价出发,分析各种常规预测裂缝有利发育带方法的优势和局限性,针对砂泥岩裂缝性储层识别这一难点,提出利用测井方法综合预测裂缝发育带的方法,指出储层裂缝预测研究存在的问题及发展趋势。
Complicated reservoirs formed by tight sandstone fractured reservoirs have become the focus of oil and gas exploration and development both at home and abroad. Conventional exploration theories and methods face many challenges in the evaluation of fractured reservoirs. Based on the evaluation of fractured reservoirs of sand and shale fractured reservoirs, In order to identify the difficulties of discriminating sandstone and shale fractured reservoirs, a method of comprehensively predicting the zone of fractures developed by well logging is proposed, and the problems existing in the research of reservoir fractures prediction are pointed out And the development trend.
