基于地震沉积学的河流相储层砂体研究
Study on Fluvial Reservoir Sand Body Based on Seismic Sedimentology
摘要: 研究区主要发育辫状河沉积，储层厚度薄，横向变化快，导致对砂体边界及砂体之间的连通性认识不清，制约了油气藏的勘探开发和剩余油的挖潜，本文以孤岛油田中一区河流相整装油藏为研究目标，以地震沉积学为基础，分析了90˚相位转换、地层切片技术、分频解释技术等关键技术的应用条件，同时结合地质、地震及测井资料研究河流相砂体分布情况，利用地震波形特征识别辫状河砂体分布及叠加结构，对类似油田储层精细研究研究具有较好的借鉴作用。
Abstract: The research area is mainly developed with braided river sedimentation, the reservoir thickness is thin, and changes rapidly in the lateral direction, which has resulted in a poor understanding of the boundaries of sand bodies and the connectivity between them, restraining the exploration and development of oil and gas reservoirs and the potential of leftover oil. This paper focuses on the braided river facies in Zone One of the Gudao Oil Field as the research target. Based on seismic sedimentology, it analyzes the application conditions of key technologies such as 90˚ phase conversion, stratum slicing, and frequency interpretation. Additionally, combining geological, seismic and well logging data to study the distribution of fluvial sand bodies, it uses seismic waveform characteristics to identify the distribution and superimposition structure of braided river sand bodies. This study is of great reference value to the fine research of similar oil field reservoirs.
