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。 The volcanic reservoirs at the bottom of the Permian Fengcheng Formation in the X72 well region, Wuxia area, northwestern margin of the Junggar Basin, are subject to complicated factors such as burial depth and seismic data. It is very difficult to identify and predict volcanic reservoirs. Based on the fine calibration of volcanic reservoirs, two different geological models are designed. By using forward modeling technique, the seismic response characteristics of volcanic reservoirs are qualitatively demonstrated as continuous low-velocity and strong amplitude reflection. Meanwhile, The existence of sets of volcanic reservoirs provides strong evidence for the prediction of volcanic reservoir distribution and well location selection in this area.
