EPS^(TM) reservoir软件在盐湖盆地储层预测中的应用

Application of EPS^(TM) reservoir software system in the reservoir prediction of salt lake basin

江汉盐湖盆地沉积由盐岩、砂岩、泥岩等混合岩相组成,在储层预测中容易造成层位标定的不确定性和波阻抗反演的多解性。EPSTMreservoir解释软件系统把地震反演技术、地震属性技术等引入到江汉含盐盆地的滚动勘探开发中,解决了上述难题。利用地震信息,结合动静态资料预测储层平面分布、厚度变化和物性参数等,是减少钻探风险,增加江汉油区原油地质储量的有效方法。

Jianghan salt lake basin is composed of impure lithofacies such as salt rock,sand stone, mud stone. So,it is easy to make demarcating horizon uncertainty and more commentaries of acoustic impedances inversion in the reservoir prediction. The seismic inversion and the seismic attribute techniques have been adhibited in rolling exploration and development by the software system of EPSTM Reservoir in Jianghan salt lake basin,it has solved difficult problems mentioned above. Using seismic information and combining dynamic material with static material information to predict horizontal distribution、thickness variation and rock physical parameters of the reservoir,which is an effective method for reducing drilling risk and increasing OOIP in Jianghan Region.
