老爷庙油田是冀东石油勘探开发公司重点勘探靶区,油气分布于由西南庄边界断裂导生的庙北背斜和庙南断鼻构造的高部位。本文结合三维地震解析成果、钻井和野外构造研究资料,利用有限元数值模拟对研究区古近系东营组东一段、东二段、东三段、新近系明化镇组四个目的层位古、今构造应力场分布及演化进行系统研究,并剖析不同层位古、今应力低值区分布特点,断裂和旁侧应力场分布以及同一断裂不同部位应力变化特点,提出了有利于油气运移聚集的有利构造样式,预测了有利的含油区块,为该区今后油气藏的勘探与合理开发提供了一定的科学依据。
Laoyemiao Oilfield is the key exploration target of Jidong Petroleum Exploration and Development Company. The oil and gas are distributed in the high part of the Miaobei anticline and Miaonan nose structures, which are derived from the boundary fault of the Southwest Zhuang Autonomous Region. Based on the data of 3D seismic analysis, drilling and field research, the authors use finite element numerical simulation to study the evolution of the four target layers of the Dongyi Section, the Dong’er Section and the Dongsan Section of the Paleogene Dongying Formation in the study area , The current tectonic stress field distribution and evolution of systematic research, and analysis of the different layers of palaeo-modern low stress area distribution characteristics, fracture and lateral stress field distribution and stress characteristics of different parts of the same fault, proposed in favor of hydrocarbon migration The favorable tectonic pattern of the congregation predicted the favorable oil-bearing blocks and provided some scientific evidences for the exploration and rational development of the reservoir in the future.
