摘要: 利用岩心、薄片、测井和压汞等资料,对枣35块火成岩储层的岩性岩相、裂缝和孔洞发育情况进行了研究,确定了火成岩储集空间的类型,建立了火成岩双重介质储集渗流模式,并结合测井解释、CT扫描和核磁共振等技术对储层基质和裂缝的有效性进行了评价.在此基础上,对火成岩裂缝性稠油油藏的开发方式进行了优选,并对蒸汽吞吐开采的可行性进行了论证,对井网部署和注采参数进行了优化.利用裂缝性双重介质热采数值模拟软件对蒸汽吞吐的应用效果进行了模拟计算,6年可提高采出程度6.4%,具有较好的经济效益.蒸汽吞吐法可作为火成岩裂缝性稠油油藏的有效开发方式.

Abstract: The data of drilling core,thin section,well logging and mercury penetration were used to investigate lithology,lithofacies and the development status of fractures,pores and abscess of igneous rock in Zao 35 Block.The reservoir space types were classified,and the double-medium storage-flow models were established.The validities of reservoir matrix and fractures were evaluated with well logging,such as CT scanning and nuclear magnetic resonance.Based on those research results,the excellent model for development of igneous fractured heavy oil reservoir was selected.The feasibility of steam huff and puff were investigated.The reasonable well pattern,injection and production parameters were optimized.The recovery performances of steam huff and puff were predicted with fractured double-medium thermal numerical simulator.The recovery percent of steam huff and puff grows 6.4% in six years.The steam huff and puff is the effective model for development of igneous fractured heavy oil reservoir.

Key words: igneous rock, fractured heavy oil reservoir, development model, steam huff and puff, numerical simulation
