摘　　要：川中磨溪气田嘉陵江组属异常高压气藏,埋藏深度3100m,地层压力67.67MPa,现有成熟井下节流工艺只适用于节流压小于35MPa的气井,不能用于这类超高压气藏,为此,针对嘉二气藏特征,开展了高压井下节流工艺应用研究,通过工具的研制、改进以及室内试验后,在磨41井投入了现场应用,取得了很好的效果。文中拟通过对磨41井高压节流效果的跟踪,进行高压井下节流工艺在磨溪嘉二异常高压气藏的适应性分析。The pressure is abnormal high in Jialingjiang reservoir of center Sichuan area, in which the depth is 3100m, the formation pressure is 67.67 MPa. The current downhole choke technology can only be used in gas well under the condition of below 35MPa, it isn't suitable for superhigh pressure reservoir. So, based on the feature of Jia'er reservoir, applied research of the downhole choke technology for high pressure wells is carried out. The corresponding tools have been developed and improved. After the tools were tested in lab., they were successfully used in Moxi 41 well. Meanwhile, the adaptability study of the technology in Moxi high pressure reservoir is been carrying out by analyzing the throttling effect of well Moxi 41.
