中文摘要:
      绥中S油田位于辽西低凸起中段,东营组二段下(E3d2L)I油组为主力油层,开发多年目前已进入高含水期。为完善海上高含水期油藏精细描述技术,该文以河流沉积学理论为依据,对S油田东营组二段下I油组各时间单元进行沉积相展布特征进行研究。在精细地层格架研究基础上,综合前人研究成果、岩芯及测井资料,结合辫状河三角洲沉积环境,详细分析各时间单元测井响应特征,并细致分类,建立测井微相模式,识别1种亚相11种微相。绘制13沉积时间单元沉积相带图,归纳总结3种沉积相模式(分枝状、朵状、片状)。由沉积演化模式分析,研究区目的层处于地层上升期对应的储层沉积沉积模式,并且研究区内主要发育分支条带形河口坝沉积。本次研究可合理有效指导后期开发调整措施。
英文摘要:
      Suizhong S Oilfield is located in the middle section of low uplift in western Liaoning.The lower I oil layers of E3d2L is the main oil reservoir.The oilfield has been developed for many years, and now it has entered a high water cut stage.In order to improve the fine description technology of offshore high water cut reservoirs, this paper, based on the fluvial sedimentology theory, studies the sedimentary facies distribution characteristics of each time unit of the lower I oil formation of the second member of Dongying Formation in S Oilfield.On the basis of fine stratigraphic framework study, this study combines previous research results, core and logging data, combined with braided river delta sedimentary environment, combined with detailed analysis of logging response characteristics of each time unit, establishes logging microfacies mode, and finally identifies one subfacies and 11 microfacies.In this study, a total of 13 sedimentary time unit sedimentary facies belts are drawn. On the basis of sedimentary facies map, three sedimentary facies models (branching, petaling and flaky) are summarized.According to the analysis of sedimentary evolution model, the target layer in the study area is in the corresponding sedimentary model of reservoir in the period of stratum rising, and the main branch of the study area is strip-shaped estuary bar deposit. This study can reasonably and effectively guide the later development and adjustment measures.
