| 摘 要： | 针对克拉玛依油田八区下乌尔禾组油藏裂缝分布复杂、孔隙度低、非均质性强的特点，综合岩心、测井、生产动态资料分析油藏裂缝特征、控制因素及其对油藏开发效果的影响，提出了裂缝型砾岩油藏开发调整的措施建议。首先从岩心及成像测井资料分析入手，确定了砾岩储层发育的裂缝类型及特征。然后通过分析区域构造演化、应力场变化及沉积岩石类型与裂缝形成的关系，揭示了裂缝形成的主要控制因素，确定了裂缝主要走向，总结了裂缝的分布规律及平面展布形态。最后结合注采井组的生产动态资料，分析了裂缝对开发效果的影响，提出了裂缝型砾岩油藏在注采井网调整、加密井设计、注水参数选取等方面的技术政策。分析结果表明，裂缝的发育程度和分布规律既是油气富集程度和油井产能高低控制因素，又是导致油藏水淹水窜、高含水开发的主要因素。而采用注采井排与裂缝走向的夹角在45°左右、低注水量的小井距五点法线状注水的井网方式可以有效提高特低-低渗透裂缝型砾岩油藏的开发效果，具有一定的应用推广价值。
