中文摘要:
      岩性油藏主要指圈闭由于自身储层的岩性变化而成藏的一种油藏类型,其特点主要是砂体规模小、储层物性差、非均质性强、油水分布复杂等,这些特点造成了储层砂体间的连通关系更加复杂,砂体展布规律性不明显。油田开发研究中,一般通过“旋回对比、分级控制、不同相带区别对待”的单油层对比方法确定井间砂体的连通关系。本次研究主要通过高邮凹陷黄珏油田戴南组的砂体连通性研究,提出“对、拆、统、验”四步法的技术,提高砂体连通性研究的准确度,为岩性油藏的油田注采层系调整、流线场调整等措施提供地质依据。
英文摘要:
      Lithologic reservoir, mainly refers to a reservoir type formed by the lithologic change of its own reservoir. Its main characteristics are small sand body size, poor reservoir physical properties, strong heterogeneity, complex distribution of oil and water, etc. These characteristics result in a more complicated connection between reservoir sand bodies, and the distribution regularity of sand bodies is not obvious. In oil field development research, it is generally controlled by "cyclic correlation, grading control," The single reservoir correlation method with different facies zones is used to determine the connectivity of sand bodies between wells. This study is mainly based on the study of sand body connectivity in Dainan formation of HuangJue Oilfield in Gaoyou Sag. This study puts forward the technology of "correct、disassembly、series and verification" four-step method to improve the accuracy of sand body connectivity research and provide geological basis for the adjustment of injection-
