摘要
It is very difficult to predict of deep high-porosity and high-permeability reservoirs in Puguang Gas Field by seismic data due to their complex lithology, lithofacies and strong anisotropy. Based on logging data of 10 wells in the gas field, two categories of reservoirs exists, which include nine kinds of reservoirs, among of which oolite subfacies, sand-gravel subfacies and reef subfacies are beneficial reservoir types of high porosity and high permeability. In this work, a lithofacies identification model for deep high-porosity and high-permeability reservoir is proposed based on high-accuracy inversion.
