摘要： Zoeppritz方程模型正演、AVO油气检测需要提供准确的储集层物性参数。这些参数在野外不可能精确获得,而实验室对岩心进行模拟测试可弥补此不足。本研究利用实验区钻孔取心岩样,在模拟地下真实温压条件下测试其弹性参数,并用精确的测试参数经Zoeppritz方程做模型正演,以获取储集层有否响应机制,再进行有针对性的AVO特殊处理。经准噶尔盆地西部地区实际资料检测,效果明显。此项工作可作为利用地震资料进行碳氢检测的一种补充。

Abstract: Forward modeling with Zoeppritz equation and AVO hydrocarbon detection require the accurate reservoir properties. However, it is unlikely to obtain them with high accuracy outdoors. Laboratory simulation test in cores can solve this problem. In this study the elastic parameters are measured in the drilling ores from the pilot area under simulated subsurface temperature and pressure, and then used to carry out forward modeling with Zoepprit equation to test the hydrocarbon indication of reservoir and to conduct special AVO processing. It can be used as a supplementary tool for hydrocarbon detection seismic data.
