【摘要】 天然气水合物是天然气与水在高压低温条件下形成的类似冰状的结晶物质,其分布广、资源量巨大、能量密度高,极具开发前景。以神狐海域为例,介绍了在无井约束的情况下,如何应用地震反演方法。通过分析阻抗值的差异及分布特征,预测神狐海域水合物的展布。整体预测效果较好。总结了预测流程及预测的成功经验,为海域水合物矿产的预测及勘探和开采提供了借鉴。更多还原

【Abstract】 Gas hydrate is a crystalline material like ice formed by natural gas and water under high pressure and low temperature.It has great development prospects for the wide distribution,huge amount of resources and high energy density.This paper introduces how to use seismic inversion to forecast the hydrates distribution without well constraint in Shenhu area by analyzing the differences of impedance values and its distribution characteristics.The forecasting results are tested well.Thus the paper will provide a basis for hydrates exploration and exploitation.更多还原
