摘　　要：对于井深超过6000 m、地层压力超过105 MPa、地层温度大于150℃的超高压油气井,井口压力控制难度大,携砂流体对设备冲蚀严重,使得测试难度大,对地面测试装备及配套工艺技术和除砂等工艺提出了更高要求。经多年的研究和现场试验,形成了一套140 MPa超高压油气井地面测试工艺流程和旋流除砂器、MSRV、高/低压导向阀等关键设备。实践证明,这套超高压油气井地面测试技术能够满足各种超高压井的测试需要,取全取准各种测试数据。To ultra-high pressure oil & gas wells whose depth is over 60000 m,formation pressure is more than 105 MPa,and temperature is over 150℃,being difficult of pressure control for wellhead and serious erosion to equipment of carrier fluid makes well test to be hard,which puts forward higher requirements for processes of surface testing equipments and the matching technologies,and desanding,etc. Through many years of development and field test,a set of surface testing process of 140 MPa ultra high pressure oil and gas wells,cyclone desander,MSRV,high or low pressure guide valve. The practice proves can meet the needs of the testing of ultra high pressure wells,acquire a complete and correct test data.
