摘要
Abstract
With the deepening of research and drilling,complex geological background and reservoir heterogeneity are awarend in Dengying Formation in the PLN area of Sichuan Basin.Reflection characteristics is changeable in Dengying Formation of the Sinian System.There are low-velocity siliceous dolomite,which is close to the reservoir in P-wave impedance,so using the P-wave impedance cannot distinguish between siliceous dolomite and reservoir,the reservoir prediction is difficult.In this paper,through the statistics of well logging data and the model forward,it is concluded that the shear wave impedance can be effectively used to identify the reservoir and the siliceous dolomite.Through the layers calibration and layers matching of real multiwave data,the interpretation of P-wave and converted wave seismic section can effectively identify the reservoir,improve the reservoir prediction accuracy.关键词
