XB地区火山岩岩相划分及储层精细刻画
|
摘要
本文从测井和地震响应特征入手,结合钻井和地质等资料,应用地震属性分析、构造趋势面分析、地震约束反演及三维可视化等综合地震预测方法,将松辽盆地XB地区火山岩相划分为爆发相、溢流相和火山沉积相三种亚相,并圈定了爆发相、溢流相和裂缝发育带等火山岩气藏有利储层。结合密度反演方法,本文按照多岩性、多门槛值提取储层厚度的原则,精细刻画了研究区火山口的古地貌、有效储层厚度及分布范围,并为实钻证实。
Based on the well logging and seismic response characteristics and by integrating with drilling and geological data, several integrated seismic prediction methods, such as seismic attribute analysis method, structure trend surface analysis method, seismic constraint inversion method and 3D visualization method were used to classify lithofacies of the volcanic rock in XB area of Songliao Basin. The lithofacies was classified to 3 sub-lithofacies, they are explosion facies, overflow facies and volcanic-sedimentary facies, and the explosion facies, overflow facies and fracture developed zone were enclosed as favorite volcanic rock gas reservoir. By integrating with density inversion method and based on the reservoir thickness extracted by multi-lithologies and multi-thresholds principle, the palaeogeomorphology, effective reservoir thickness and distribution range of the volcanic crater in the study area were carefully delineated and then were proven by drilling.
