中文摘要:
      针对迪那气田存在的平面非均质性强、气藏层间动用程度不清等难题,在前人研究基础上,参考区域地层资料,采用“旋回对比,分级控制,井震结合”的油气层对比方法,对迪那气田古近系的苏维依组和库姆格列木群进行精细地层对比,气层组的划分主要依据稳定分布的一级标志层,砂层组的划分依据二级标志层及沉积旋回特征,小层的划分依据沉积旋回及岩性变化特征。根据以上地层划分对比原则将迪那气田古近系含气层系共划分为2个气层组,8个砂层组和38个小层。同时结合地震资料,识别了过井断层11条,有效的解决了过井断层识别难的问题,也为迪那气田合理开发技术政策的制定奠定了基础。
英文摘要:
      Complex Horizontal heterogeneity and unclear reservior producing level are two of the problems in Dina gas field. On the basis of an adequate understanding of previous research the characteristics of the regional stratigraphic, the reservoir comparison methods “cycle comparison, step control, combination of well drilling and seismic” were used to carry out detailed comparative study on Paleocene Suweiyi Formation and Kumugeliemu group. The division of gas –bearing formation was mainly based on the stably distributed primary marker bed, and the division of sand formation was based on secondary marker bed together with the characteristics of sedimentation cycle, and the division of subzone is based on characteristics of sedimentation cycle and lithological change. Following the presented stratigraphic division and comparison principle, the gas bearing reservoir of Paleocene in Dina oil field were divided into 2 gas formations, 8 sand formations and 38 subzones. And by combination of seismic data, 11 cross-well faults were identified, so the difficulty to identification of cross-well faults was effectively handled, and this also set the foundation of policy making of reasonable development techniques.
