渤海油田稠油井优快测试技术

优快测试技术是针对渤海地区海上一些稠油层原油粘度高、地层出砂严重等特点设计出的一项新工艺 ,它将常规 DST工具与螺杆泵稍作改动后组成多功能测试管柱 ,一次下井完成DST测试和螺杆泵机采两项作业 ,既能取得完整的井下压力资料 ,又能了解地层的产能和液性。现场应用证明 ,该测试技术效率高、效果好

High Quality and Quick DST Technique of Viscous Oil Wells in Bohai Oilfield.

High quality and quick DST technique is a new technology designed in accordance with high oil viscosity,largevolume sand production and other features of some viscous oil formations on Bohai offshore, it combinesconventional DST tools and screw pump slightly modified to form a multi-function DST string,once the string isrun into the well, two operations of DST test and mechanical oil production with a screw pump will becompleted,it may not only obtain complete downhole pressure data,but understand formation productivity andflow properties. Field application proves that the DST technique has high efficiency and good results.
