| 摘 要： | 文中针对阿姆河盆地A区块碳酸盐岩储层对纵波属性敏感的特性,以地质、测井信息为约束条件,通过拾取三维地震波的速度、有效振幅、频率等信息,应用地震相控非线性随机反演,对A区块主要目的层的储层分布特征进行了预测,获得以下认识:①阿姆河盆地A区块碳酸盐岩具层状反射特征,顶、底界为两组强反射,内部可以看到成层性较好、连续分布的反射波,碳酸盐岩储集空间主要以孔隙型为主,裂缝不发育,偶见微型溶孔、溶洞;②在研究区平面上的低速异常区为碳酸盐岩储层发育区带,低速异常区主要位于工区偏南部的东、西两端,其余大部分为较高的速度发育区,在构造高部位的低速异常带为有利钻探位置;③垂向上不同岩性在反演剖面上表现为不同的速度特征,即浅部的碎屑岩速度最低,中部膏盐层速度明显高于上部碎屑岩,下部碎屑岩层受压实作用影响速度高于上部碎屑岩层,主要目的层碳酸盐岩的速度最高。根据预测结果部署的两口探井均产出高产天然气流,证明地震相控非线性随机反演的预测结果准确、可靠。

| Abstract: | Focus on carbonate reservoir characteristics sensitive to P-wave attributes in Block A of Amu-darya Basin,we picked the velocity,amplitude and frequency from 3D seismic data constrained by geological and logging data,and then we applied facies-controlled nonlinear random inversion for carbonate reservoir prediction in Block A of Amu-darya Basin.The following observations were obtained.First,carbonate rocks have bedded features in Block A of Amu-darya Basin.Two strong reflections were found at the top and th... |
