海相碳酸盐岩储层成岩作用对岩石波速的影响
Impacts of the Diagenesis of Marine Carbonate Reservoir on Seismic Velocity
摘要
Abstract
In the conversion relationship between porosity and wave velocity, the rock wave velocity of marine carbonate rocks reservoir fluctuates distinctly under given porosity. This phenomenon arises from the complex diagenesis of carbonate rocks, which would lead to the multiplicity of inversion and interpretation for seismic reservoir. Therefore, it is of great significance to establish a predictable relationship between diagenesis and the rock wave velocity in the process of prospecting oil and gas in marine carbonate rocks. In this thesis, research findings about the relationship between diagenesis and seismic velocity home and a-broad have been collected, which lays a foundation for exploring the variation of rock wave velocity in diagenesis process. Through these research findings, we also found that differences in diagenetic history, pore type and dolomite type would give rise to distinct fluctuation of rock wave velocity under given porosity. On this base, we conducted a simulated experiment of seismic section on the Feixianguan Formation oolitic beach in Sichuan Basin. We discovered that it is feasible for us to predict reservoir diagenetic facies according to seismic data. We suggest that we intensify our research on the relationship between diagenesis and the rock wave velocity from now on, so as to provide some guidance for China's exploration of oil and gas in deep marine carbonate rocks.关键词
