摘要
由凝析气恒容衰竭试验实测出的PVT数据,推算出每压力级下各组分的相平衡常数,用该常数判断实测的PVT数据质量。对10组凝析气样品进行了实测数据检验。应用表明,该方法比较简便、可靠。通过调节每级排放气体的压缩因子、前两级反凝析液体量和汽相组成,能使实测PVT数据满足检验要求。
This paper presents a method for evaluating PVT data during constant volume depletion (CVD) process for gas condensate. Ten samples were tested. Results show that the method is simple and reliable. For the purpose of obtaining satisfactory PVT data, it is recommended to tune measured gas compressibility factor of each pressure stage, retrograde condensation liquid volume of the first and second stages and vapor composition.
