| 摘 要： | 根据渗流理论考察了钻井过程中泥浆滤液对含油气储层的侵入过程，研究了不同条件下侵入剖面的特点，计算了各种侵入剖面的补偿密度和补偿中子测井响应，并提出了新的解释模型．研究结果表明，侵入改变了近井区地层的物性参数和地球物理特征，给测井地层评价带来许多问题，但又为储层动态特性研究提供了良好的条件．

| Abstract: | According to the theory of tWo-phase imAnscible Percolation, the processes of mud filtration invading into oil and gas reservoir layers while drilling are examined,then the characteristics of invasion profiles are inveshgated, and the responses of compensated density and neutron logs to the profiles under different conditions are calculated, finally an improved interpretation model is created. The resultS show that the changes of physical and logging parameters of the reservoir rock around the borehole give rise to many difficulties for quantitative interpretation but create favorable conditions for dynamic analyses of reservoirs. |
