摘要
最近几年里,页岩气已经进入商业勘探开发阶段,但是页岩气作为非常规油气,需要利用水平井及大规模压裂,获得较高产量.为了对页岩气藏的可改造性进行评价,从单井岩石物理分析入手,优选拉梅常数*密度参数指示页岩层脆性矿物含量,开展叠前AVO同步反演,预测页岩层脆性矿物含量,进而优选页岩气藏工程"甜点区".
In recent years,shale gas exploration and development has entered to the commercial stage,but as unconventional oil and gas shale gas requires the use of horizontal wells and large-scale fracturing,get a higher yield. In this paper,in order to transform the shale gas reservoirs can be evaluated,starting from a single well petrophysical analysis,preferably Lame constants＊density parameter indicates brittle shale mineral content,to carry out pre-stack AVO inversion synchronization,forecasting brittle shale mineral content,and more preferably shale gas reservoir engineering“sweet zone”.
