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.
The Zoeppritz equation model forward and AVO oil and gas surveys need to provide accurate reservoir property parameters. These parameters cannot be accurately obtained in the field, and laboratory simulation tests on the core can make up for this deficiency. This study uses borehole coring in the experimental area. Rock samples are tested under simulated real-world temperature and pressure conditions and their elastic parameters are tested. The precise test parameters are used to model the Zoeppritz equation to obtain the response mechanism of the reservoir and then to perform targeted AVO special treatment. The actual data detection in the west of Junggar Basin has obvious effects. This work can be used as a supplement to hydrocarbon detection using seismic data.
