- 摘要:
- 为深化浅水三角洲沉积储层非均质性精细表征与分析,在浅水三角洲沉积砂体叠置的基础上,对浅水三角洲沉积约束下的6种河道接触建立精细地质模型。在此基础上搭建数值试井模型,建立了衰竭开发模式和注水开发模式下相应的水平井试井响应图版,并以此确定各类叠置模式下储集层的连通能力。通过河道叠置模式试井分析,明确不同叠置模式的试井响应特征,在基于地震、测井、沉积等研究的地质构型成果基础上,结合实际井试井分析,进一步完善了构型研究成果,成功指导了调整井井位部署,并取得了良好的开发效果。该研究成果可为浅水三角洲沉积储层及其地质模式研究和井位部署提供依据。
In order to deepen the fine characterization and analysis of the heterogeneity of shallow-water delta sedimentary reservoirs, the fine geological model of six kinds of river channel contact constrained by the deposition of shallow water delta is established based on the superimposition of sand bodies in shallow water delta reservoir. On this basis, the numerical well test model is built, and the corresponding horizontal well test response charts under depletion development and water injection development are established, upon which the connectivity of reservoirs under various contact modes is determined. Through the well test analysis of superimposition mode, the well test response characteristics of different modes are clarified. On the basis of geological configuration results from seismic, logging and sedimentation studies, combined with well test analysis of actual wells, the research results of configuration are further improved, which successfully guides the well location deployment and achieves good development effect. The research results provide the basis for the study of shallow water deltaic sedimentary reservoirs, and its geological model and well location deployment.
