| 摘 要： | 岩性油藏砂体规模小、非均质性强、油水分布复杂等特点造成了砂体间的连通关系复杂,砂体展布特征不明显。在"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连通关系,研究"对、拆、统、验"四步法,提高了高邮凹陷黄珏油田戴南组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。

| Abstract: | The lithologic reservoir is characterized by small scaled sand bodies, strong heterogeneity and complex oil-water distribution, which results in the complicated connection between reservoir sand bodies and unclear distribution regularity of sand bodies. Based on the single reservoir correlation method with "Cyclic Correlation, Grading Control, Different facies zones are differently treated" is used to determine the connectivity of sand bodies between wells. "Correct, Disassembly, Series and Verification", the four-step method was used to improve the accuracy of sand body connectivity research in Dainan formation of Huangjue oilfield in Gaoyou sag and provide a geological basis for the adjustment of injection-production series and streamline field in lithologic reservoirs. |
