鄂尔多斯盆地塔巴庙区块下石盒子组砂岩储层含气性预测
摘要
针对鄂尔多斯盆地塔巴庙区块下石盒子组砂岩储层预测的重点和难点,结合其地质、地球物理特征,采用地震属性提取技术、地震测井联合反演技术、可视化解释技术等,初步建立了一套适合该区地质特征的三维储层预测的技术方法。查明了下石盒子组目的层段储集体的空间展布特征,预测了目的层段含气性特征。在此基础上,对研究区进行了评价,划分了有利储层发育带及有利含气储集带。对本区的天然气勘探开发起了重要指导作用。
A set of techniques of prediction of 3D sand reservoirs suitable to the geological characteristics of the Lower Shihezi Formation in the Tabamiao area,Ordos basin,has been preliminarily established according to the key and difficult points of prediction in the area,combined with its geological and geophysical characteristics,and based on the seismic attribute extraction technique,seismic and well logging inversion technique and 3D visual interpretation technique.By using this set of techniques,the authors have ascertained the spatial distribution characteristics of the sand reservoirs of the target zone of the Lower Shihezi Formation and predicted the gas-bearing features of the target zone.On that basis,the study area is evaluated and the favorable reservoir zone and gas accumulation zone are determined.This study may guide gas exploration and exploitation in the area.
