摘　　要：普光礁滩储层非均质性强,储层内含流体性质复杂,使得钻遇干井和水井的风险很大,地震识别流体难度较大。针对这一问题,本文依据普光长兴组岩石物理模型,开展了地震含气性影响关键因素与储层参数的关系研究,通过地震叠前道集正演结果,表明利用单一参数(拉梅常数)预测流体性质存在多解性,为此需要构建不同类型储层流体敏感因子气检方法,综合利用多种方法来预测长兴组生物礁的储层含气性。Puguang reef beach reservoir has strong heterogeneity and complex fluid properties.The risk of drilling dry and water wells is very high,and it is difficult to identify fluid by seismic method.In view of this problem,this paper is based on the rock physical model of Puguang Changxing Formation.The relationship between key factors affecting seismic gas-bearing property and reservoir parameters is studied.The results of seismic prestack gather forward modeling show that there are multiple solutions for predicting fluid properties by using a single parameter(Lame constant).Therefore,it is necessary to construct gas detection methods for fluid sensitive factors of different types of reservoirs,and synthetically use various methods to predict reservoir gas-bearing property of reefs in Changxing Formation.
