利用岩心、测井、录井、粒度和分析化验等资料,分析认为东营凹陷永安镇油田永3断块沙二段发育一套典型的进积三角洲沉积体系。通过对岩性、粒度概率累积曲线及电性特征等的研究,建立了永3断块进积三角洲的沉积体系,分析了研究区内三角洲的填充序列,通过对典型小层沉积微相的研究,明确了储层的分布规律,为开发中后期油气藏的沉积微相研究提供了较好的地质基础。
Based on the data of core, well logging, logging, grain size and analysis, a typical sedimentary system of sedimentary delta was developed in the second member of Shahejie formation of Yong 3 fault block in Yonganzhen Oilfield, Dongying Depression. Through the study of lithology, cumulative probability curve of grain size and electrical characteristics, the depositional system of the delta of the Yong 3 fault block has been established, and the filling sequence of the delta in the study area has been analyzed. Through the study of typical small sedimentary microfacies , Clarified the distribution of reservoirs and provided a good geological basis for the study of sedimentary microfacies in the middle and late stages of oil and gas reservoir development.
