摘要
在气井临界携液流量计算中,Turner模型计算结果偏高,应采用修正模型计算。沙坪场气田天东82、天东29井曾经因为产量低于临界携液流量而产生井底积液,根据两口井的生产数据计算得到模型中的修正系数α=0.66。将修正模型成功试用于天东91井的临界携液流量计算后,应用该模型对沙坪场气田所有气井进行了井口、井底临界携液流量分析,并得出结论:在相同管柱内径下,高压气井最大临界携液流量易出现在井口,而低压气井最大临界携液流量易出现在井底。
A higher critical liquid-carrying flow rate is calculated by Turner model,so a correction model should be adopted in this calculation.Bottom-hole accumulation ever occurred in both Tiandong 82 well and Tiandong 29 well of Shapingchang gasfield because the production was lower than the flow rate of critical liquid carrying.Through production data of the two wells,a correction factor of the model,α=0.66,is obtained.The correction model is successfully applied to the calculation of critical liquid-carrying flow rate of Tiandong 91 well.Subsequently,the wellhead and bottom-hole flow rate of all wells in Shapingchang gasfield has been analyzed by the model.Results indicate that with the same inner diameter of pipe string,the maximum critical liquid-carrying flow rate of high-pressure well usually appears at wellhead,whereas that of low-pressure well appears at bottom hole.
