王家岗地区主要发育沙四上亚段滩坝砂岩、浊积岩油藏。在沙四上亚段沉积时期,受古地貌控制,区内发育滩坝、浊积岩等多种沉积体系,不同类型岩性体叠置关系复杂,导致储层预测难度较大,影响了研究区油气勘探与开发。为了获取储层展布,本文应用地震储层反演技术,针对该区地质特点进行了声波曲线重构,对反演模型进行地震储层反演,并通过误差分析验证,得到较好的反演效果,完成了沙四上亚段各个砂层组储层平面分布的预测,对明确油气分布规律具有指导作用。 The Wangjiagang area mainly develops sand dam and turbidite reservoirs with sandbodies and sandstones in the Upper Shahejie Formation. During the sedimentary period of the Upper Es4, controlled by paleogeomorphology, many sedimentary systems such as beach dams and turbidites developed in this area. The stacking of different types of lithologic bodies is complex and leads to the difficulty of reservoir prediction and affects the research District Oil and Gas Exploration and Development. In order to get the reservoir distribution, this paper uses the seismic reservoir inversion technology to reconstruct the acoustic curve according to the geological characteristics of the area, and performs the reservoir inversion on the inversion model. The error analysis shows that the inversion is good The result of the prediction shows that the prediction of the plane distribution of various sandstone reservoirs in the Upper Member of the Fourth Member of the Fourth Member of the Shahejie Formation plays a guiding role in defining the law of oil and gas distribution.
