| 在研究储层形态特征和地层分布状况的过程中,精细地层划分与对比是经常用到的手段之一。同时,它也是进行油藏描述的前提与基础。地层对比结果的准确与否将会直接影响到其它方面研究的可靠性,如小层顶面构造解释、沉积微相的认识,砂体及油层分布特征的认识,以及地质模型的建立和剩余油分布的认识等等。本次研究,综合利用了地震、测井、岩性等资料,采用“井震结合”的方法,对研究区能够钻遇沙四段的113口井的岩、电性进行分析,对辽河油田欢喜岭采油厂沙河街组沙四段进行了精细化分与对比,并将沙四段由上至下划分为和Te 、DuⅠ、DuⅡ、DuⅢ4个地层单元。 沙四段的精细地层划分与对比,为油田在开发期研究砂体展布、沉积微相等提供了地质基础数据,对油田的开发具有一定的指导意义。 |

| In the process of studying the reservoir characteristics and formation distribution, fine stratigraphic classification and correlation is a kind of the common used means, at the same time, it is also the prerequisite and foundation for reservoir description. the accuracy of Stratigraphic correlation results ｗill directly affect the reliability of the other aspects of research,such as Small layer of the top surface structural interpretation,cognition of microfacies,the understanding of sand body and the characteristics of reservoir distribution,the establishment of geological model and the understanding of the remaining oil distribution, etc．This study comprehensive used seismic, logging, and lithology information,ａdopt the method of ＂Wells and seismic＂according to the drilling through four segment sand , it searches the rock and electricity of 113 wells, it also divides and analyses subtly the four segment sand in the formation of Sha He street, Oil Factory in Huan Xi Ling, Liao He oil field. It divides the four segment sand into four stratigraphic units: Te 、DuⅠ、DuⅡ、DuⅢ. The partition and comparison of four segment sand, provides basic Geological data to the researches of sand distribution and sedimentary microfacies during the oilfield development, so it is of guiding significance to the oilfield development. |
