[Abstract]:The main purpose of the study in Block 8 of Yushulin Oilfield is Fuyu reservoir, Yangdachengzi reservoir, located in the third and fourth member of Quantou formation. The understanding of sedimentary microfacies and the distribution of physical properties have become the main problems restricting the potential of remaining oil. In order to solve these problems, it is very important to establish fine reservoir model. Therefore, based on the core, logging and seismic data, this paper studies the modeling of Fuyu reservoir and Yangdachengzi reservoir by using random simulation technology, and obtains the following results and understanding. Firstly, based on core, logging and seismic data, the fine isochronous stratigraphic framework of Fuyang reservoir is established. On this basis, the distribution of sedimentary microfacies in each time unit of Fuyang oil reservoir in the study area was studied in depth, and the sedimentary environment was found to be a meandering river-shallow water delta sedimentary system. The sequence of phase transformation from Yangdachengzi reservoir to Fuyu reservoir is as follows: meandering river facies delta plain subfacies delta front subfacies and total positive cycle. Then, using the method of combining well and earthquake to describe the structural form of the study area in 3D seismic data body, and clarify the small fault, the structural form of the study area is "north high and south low, east high and west low", and the faults are developed. The inheritance of fault features is good, which provides accurate and reasonable structural information for reservoir model. Finally, based on the results of plane sedimentary microfacies and seismic structural interpretation, the top structural model of 6 reservoirs and the sedimentary facies model of 75 time units are established, and the sedimentary microfacies are used as constraints. The random modeling of pore and permeability data is carried out by using sequential Gao Si simulation method, and the reservoir physical property model in the study area is established, which can guide the further understanding of oil-water distribution, connectivity and vertical relationship in each layer of Fuyang oil layer. It provides reliable basis for the next exploration and development of oil field.
