摘要:

根据岩石物理的分析方法,针对青藏高原木里地区DK1井孔143.40~144.20m含水合物层段和DK4井孔165.80~166.35m含水合物层段,分析水合物在岩层孔隙中的填充模式。首先采用时间平均公式估算含水合物粉砂岩的物性参数,然后依据弹性模量模型方法构建岩石物理模型,其中模式一是将水合物看作孔隙充填物的一部分,模式二是将水合物看作岩石骨架的一部分,分别基于不同的模式计算含水合物岩层的纵波速度和横波速度,并比较2种模式的速度差异。最后通过理论计算的曲线与实际采样点数据对比,推测该地区岩层中水合物的填充赋存方式符合模式二,认为将该层段水合物作为骨架的一部分进行分析,更能反映真实含水合物地层的物性特征。

Abstract:

Based on the rock physical method,filling-models of natural gas hydrate was analyzed in the Muli region of Qinghai-Tibet plateau.The primary data contain different kinds of logging data of DK1 and Dk4,in the depth of 143.40-144.20m and 165.80-166.35m,respectively.Firstly,we estimate several physical properties of siltstone of hydrate by Time average equation.Secondly,rock physical models of gas hydrate are established by the method of Elastic modulus model.According to rock physics,we use two assumptions: Model 1,the gas hydrate is taken as a part of the infilling in pore;Model 2,the gas hydrate is taken as a part of the rock matrix.We calculate the velocities of the layer model on the Model 1 and Model 2 respectively to compare the differences.Thirdly,on the basis of the velocities curves by the theoretical calculations and the sampling data in situ,we suggest that the filling-model of the siltstone is in accord with Model 2 in the DK4 of the depth of 165.80-166.35m.

Key words: Natural gas hydrate, Filling-models, Rock physics, Velocity, Elastic modulus
