地震多属性反演在巴喀气田八道湾组储层预测中的应用
|
摘要
巴喀气田位于吐哈盆地台北凹陷,下侏罗统八道湾组致密砂岩储层是巴喀气田重要的产气层位。选择地震多属性反演方法,建立已钻井点储层参数与多种优势地震属性之间的函数关系,进而依据其关系反演得到储层参数数据体。该方法精度高,可以精细刻画储层空间分布特征。将该方法应用于巴喀气田八道湾组的储层预测研究,通过反演得到目标储层的自然伽马和孔隙度信息,预测出了储层含气砂体的分布规律及范围,统计分析表明预测结果与实际钻井油气显示吻合度较高。
Baka gas field is located in Taibei sag of Tuha Basin , of which the tight sandstone reservoir of lower Jurassic Badaowan formation is the important gas production horizon.In this paper we chose seismic multi-attribute inversion method to establish the function relationship between the reservoir parameters of drilled wells and the optimized seismic attributes , by which a data volume of reservoir parameters can be obtained.This method has a high precision and can be used to describe the distribution characteristics of reservoir space in detail.The method was applied to reservoir prediction research of Badaowan formation in Baka gas filed , through the inversion we obtained the information of natural gamma and porosity of target layer , predicted the gas-bearing sand body distribution regularity and its distribution area of reservoirs ; statistical analysis showed that there is a high coincidence degree between the prediction and the drill.
