稠油高凝油井电加热螺杆泵与地层测试器联作试油工艺

The technology of joint work of electric heat screw pump and formation tester is an advanced one for production test in heavy oil well or in well where oil is with high freezing point. It better solves the problems of production test and draining in the particular reservoirs. The draining of the screw pump can actually reflects the liquid property and productivity of the formation; special cable in the hollow rod can increase the fluid’s temperature, reduce its viscosity, and therefore enhance the mobility; the formation tester can be used for acquiring formation pressure, temperature and so on. Field application indicates that this technology is with better application future.

试油提升设备及其游动系统的改进方法探讨

在深井试油作业过程中 ,TJ2 0型通井机与目前油田拥有的井架及游动系统配合使用时 ,由于游动系统的穿绳数以及绞车滚筒与水刹车之间的传动比不合适 ,导致作业效率低。现场使用中 ,存在为提高效率而不挂水刹车的现象 ,致使刹车副磨损严重 ,而且还存在环境污染和安全问题。文章分析了不同绳数游动系统的速度和载荷提升能力 ,为提高TJ2
