长期以来,人们在大范围内进行了从储层内有效采收急于开发的石油天然气资源的基础研究,本文就此做了叙述。其内容包括:目前在美国以非原生型天然气而引人注目的煤层气的扩散排出速度的测定,并对日本主要煤矿煤层进行了调查研究,进而针对储层的气体渗透性,建立了通过岩石的毛细管压力、孔隙径分布测定等来测算渗透率的方法,还研究了由于封闭压力对岩石的影响、气体压力、气体组成的变化而引起的渗透率变化。在关于EOR(三次采油)的研究中,探讨了表面活性剂的化学结构与采收能力的关系。及水蒸汽驱油法中的化学药品使用效果,获得了很有参考价值的成果。
For a long time, people carried out a wide range of basic research on the effective recovery of oil and gas resources that are eager to be developed from the reservoir. This article describes this. The contents of this study include the determination of the diffusion rate of coal-bed methane, which is currently attracting attention in the United States with non-native gas, and the investigation of coal seams in major coal mines in Japan. Based on the gas permeability of the reservoir, Capillary pressure, pore size distribution measurement to measure the permeability of the method, but also studied the closure of the pressure on the rock, gas pressure, gas composition changes caused by changes in permeability. In the study of EOR (tertiary recovery), the relationship between the chemical structure of the surfactant and its ability to recover was discussed. And water vapor oil displacement method in the use of chemicals, access to a lot of reference value of the results.
