摘要
Abstract
Influenced by the small number of exploratory wells in the HK gas field of Xihu Depression and the similarity of AVO types of different fluids,the fluid properties of the reservoir in the study area cannot be effectively identified using the traditionally derived hydrocarbon detection attributes,and there is an urgent need to search for an effective hydrocarbon detection method suitable for this area.Through the single-point pre-stack AVO forward simulation of the drilled wells in HK gas field,we establish the intercept and gradient intersection volume plate for fluid identification in the study area,and the gas-bearing sandstones show obvious AVO characteristics of Class Ⅱ～Ⅲ,and different fluid types are basically distinguishable in the volume plate.Based on this,we propose the scalar Poisson's ratio attribute by borrowing the idea of Poisson impedance,which can enhance the sensitivity of the identification of gas-bearing nature in the study area in medium-depth hydrocarbon detection in the Xihu Depression has achieved good application results.关键词
