摘要
本文在用VSP资料标定鄂尔多斯盆地中部奥陶系风化壳储层段反射层的地质层位基础上,采用模型正演研究了储集层反射特征的变化,提出频率、速度是影响波形特征的主要因素,进而根据地震剖面结合地质资料,预测了盆地中部储集层的平面展布和厚度变化,为风化壳气藏的勘探部署提供了依据。
Based on demarcating the geological position of the reflection horizon of the reservoir member in the weathered crust of Ordovician in the central part of Eerduosi Basin by use of VSP data,this paper researches the change of the reservoir reflection characters,applying the forward modeling and proposes that the frequency and velocity are the main factors affecting the waveform characters,then forecasts the lateral distribution and thickness change of the reservoir in the central part of the basin in the light of seismic sections and combining with geological data, which provides some bases for disposing the exploration of gas reservoirs in the weathered crust.
