Device and method for pumping a viscous liquid comprising injecting a thinning product, application to horizontal wells |
摘要 |
A device for pumping a fluid of high viscosity containing a gas and a liquid phase which includes a pump connected to a lower end of a tubular string at the bottom of a well and a device for separating free gas from the liquid phase and for injecting a thinner into the fluid to reduce the viscosity. Injection of the thinner is effected at fluid inlet ports of an inlet device for separating the free gas via a pipe leading to the surface of a geological formation in which the well is positioned. Also, a pumping method using the device involves injecting the thinner into the fluid of high viscosity near an inlet of the pump.
