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。

The Lower Urho reservoir of NO. 8 district of Karamay oil-field is characterized by complicated fracture distribution, low porosity, and strong heterogeneity, etc. In view of these characteristics, by using core, well log, dynamic production data, these contents are analyzed, which are the fracture characteristics, main control factors of fracture formation, and influence on development effectiveness, etc. Development adjustment proposal measures of fracture conglomerate reservoir were put forward based on the fracture research. The concrete steps are as follows: Firstly, the types and characteristics of fracture conglomerate reservoir are defined on the basis of reservoir cores analysis and imaging logging data interpretation. Secondly, the main control factors of fracture formation is revealed, the major fracture strike is determined, and the fracture distribution and plane extension in the oil reservoir are summarized by analyzing the relation among regional tectonic evolution, the change of stress fields, and the types of sedimentary and fracture formation. Finally, by combining dynamic production data of injection-production well group, the influence of fracture identification on development effectiveness is analyzed. And technology policies on fractured conglomerate reservoir development are pointed out; the policies effectively apply the fracture research results on the adjustment of injection production well pattern, the adjustment of well design, and selection of injection parameters. The practical results show that both the deliverability of oil well and water flooding, water breakthrough, and high water content in well are controlled by fractures development degree and distribution pattern. And a good spatial disposition relationship between injection production wells and fracture is about 45°. High efficiency development for the low-permeability fractured conglomerate reservoir is obtained by the close spacing development, whose characteristics are low water injection rate, five points well pattern form of law, and linear injection. And they could be certainly applied to other similar reservoirs.
