摘要:

准噶尔盆地西北缘乌夏地区X72井区二叠系风城组底部火山岩储层发育,受埋深、地震资料等复杂因素的影响,火山岩储层识别和预测非常困难。在火山岩储层精细标定基础上,设计了2个不同的地质模型,运用模型正演技术方法,定性论证了火山岩储层地震响应特征为连续低速强振幅反射,同时预测了风城组下部另一套火山岩储层的存在,为该区火山岩储层分布预测及井位优选提供了有力证据。

Abstract:

At the bottom of the Permian Fengcheng Formation in northwest rim X72 block of the Junggar basin, the volcanic reservoir is developed. It is hard to identify and predict the volcanic reservoir because of the deep buried and complex seismic data. In this paper, we design two different geologic models to qualitatively demonstrate the seismic response characteristics of the volcanic reservoir after the fine calibration of the volcanic reservoir. We use the forward solution method to not only identify the continued, low velocity, and strong reflection, but also predict another set of volcanic reservoir under the Fengcheng Formation. This result will offer the strong evidence to predict the reservoir and plot well.

Key words: Forward modeling, Volcanic reservoir, Seismic response, Permian.
