摘要
通常,试井分析方法基于单相渗流基础上,但在实际生产中,尤其是凝析油气田开发中后期,地层和井底附近经常发生两相或三相同时流动的多相渗流情况,需要对单相流试井理论方法加以实用有效的修正。从凝析气藏相态变化与渗流机理、产能和压力分析三个方面,对油气两相试井研究现状进行了总结和评述。对开展和推广多相流试井解释具有重要意义。
Conventional well testing analysis method is based on single phase flow,but during practical production,especially at the middle-late exploiting stage for oil and gas field,for multiphase percolation situation with two or three phases flowing at the same time often existing in the formation and nearby bottom hole,it is needed to effectively correct well test theory and method of single phase flowing.Summation and evaluation are given about present situation of well testing analysis from three aspects of variation of phase for condensate gas reservoir,percolation mechanism and productivity and pressure analysis.It has an important significance to develop and spread well test interpretation about multiphase percolation.
