Study On Inversion Method Of Carbonate Reservoir

Carbonate reservoirs are a very important component of the world's oil and gas reservoirs,and half of the world's oil and gas reserves come from carbonate reservoirs.Carbonate reservoirs are different from traditional sandstone reservoirs,and diagenetic effects are greatly affected by diagenesis.Leading to its complex structure of oil and gas,underground geological structure.Although carbonate rock has long been a hotspot in exploration and inversion,the method of high precision prediction of carbonate reservoir is still being studied.In the process of carbonate reservoir prediction,three different key technologies are proposed for different types of carbonate reservoirs,seismic inversion,fluid detection and fracture detection.Reservoir prediction based on post stack inversion,The fluid detection technology is the key to predict the potential of traps and the distribution of oil and gas,while the crack detection is to provide a support for fine prediction of reservoir space.In this paper,the Carboniferous carbonate gas reservoirs in the Asa study area of the southern Hanchu-Sarethu basin are discussed from the carbonate reservoir formation type,and the "fractured-porosity" reservoir characteristics are combined with fine structural interpretation The results show that the carbonate reservoirs are described and evaluated by post-stack seismic inversion,fluid detection and fracture detection,and the characteristics of carbonate reservoirs,fluids and fractures are comprehensively analyzed.A New Method for Predicting Seismic Reservoirs of Targeted Carbonate Rocks.The prediction method is applied to the actual data,and carbonate carbonate reservoir model is analyzed from four perspectives to evaluate the favorable target of the carbonate reservoir in the study area.
