M气田嘉陵江气藏的显著特点是压力高、产量低,针对这一特点,我们着重在集输工艺、设备选型上予以认真考虑,即在进行工艺设计时,改水套加热炉上针形节流阀为油嘴控制生产,从而保证了这一超高压气藏的顺利开发。 1986年2月,M5井嘉陵江气藏试油资料为:原始地层压力(推算值)65.86MPa,井口油、套压分别为25.48MPa、35.28MPa时,日产天然气10.86×10~4m~3/d,井口流动温度为17℃。按过去工艺设计,加套 M gas field Jialing River gas reservoir is characterized by high pressure, low output, in view of this feature, we focus on the gathering process, equipment selection to be seriously considered, that is, during process design, change the water heater on the needle Throttle control nozzle for the production, thus ensuring the smooth development of this ultra-high pressure gas reservoir. In 1986 February, M5 well Jialingjiang gas reservoir oil test data: the original formation pressure (estimated value) 65.86MPa, wellhead oil, casing pressure were 25.48MPa, 35.28MPa, Nissan natural gas 10.86 × 10 ~ 4m ~ 3 / d Wellhead flow temperature of 17 ℃. According to the past process design, add sets
