Manufacture Procedure for Steam-lift Tower Introduction to EPTA Technology

汽提塔的制造EPTA工艺技术

The Effect of Level distributed Force Occurred in the Steam Drum Lift-up on Lift ing

汽包抬吊中水平分力对吊装的影响

The advantages of steam-pig lift technology are obvious: firstly, the injected steam can reduce viscosity of thick oil by heat up wellbore and reservoir, secondly, steam mixes up with oil formation liquid to reduce the density of lifting liquid;

其优势体现在：蒸汽向井筒和地层传热，能有效降低稠油粘度；蒸汽与进入举升通道的地层液混合，能降低举升液柱密度、减小了井筒压力梯度；

The law of flow coefficient affected by valve lift, refrigerant inlet density and refrigerant outlet steam quality was investigated based on quick-open ball thermal expansion valve.

以球型快开热力膨胀阀为对象，采用试验方法研究阀开度以及进口制冷剂密度、出口干度对膨胀阀流量系数CD的影响规律。
