摘要
为了掌握地层流体的渗流规律 ,基于超声波测试技术 ,建立了一套可用于多孔介质中相态研究的测试装置。用石英砂作多孔介质 ,研究了在多孔介质中的露点 ,对CO2 的露点压力进行了测试 ,发现多孔介质对露点压力存在影响 ,离临界点越远 ,这种影响越大。
The process of producing oil and gas is that oil and gas seep under the stratum pressure in porous media. The high pressure character under the stratum liquid is an important parameter. To grasp seepage flow rule of stratum fluid,a set of test device for porous medium phase state reasearch based on ultrasonic technology is developed. Using Quartz sand as porous medium,the dew point of carbon dioxide in quartz sand is investigated. The experiment show porous medium has influence on the dew point of carbon dioxide,and leave the critical point of carbon dioxide the farther,this kind of influence the bigger.
