摘要： The invention pertains to the oil production and can be used in wells equipped with electric pumps namely electric submersible pumps. The method of exploitation of well by pumping unit with variable-frequency drive comprises periodic repetition of the cycles including pumpdown, search for frequency when delivery stops and accumulation and at the same time to ensure such extraction of fluid from well which is equal to its inflow it is necessary to choose unit with higher capacity in comparison with inflow of fluid from formation into well and during the cycles the pumpdown-accumulation ratio is corrected depending on the results of the previous cycles until the pumpdown-accumulation time ratio stops to change and the torque at which the delivery stops is determined based on the equality of the current torque of the downhole motor shaft and check torque which is pre-determined based on stepwise drop of torque of the downhole motor shaft in the point when delivery stops when supply voltage is decreased. The device for implementation of the method contains pumping unit placed in the production casting string consisting of electrical submersible pump and downhole motor suspended on the downhole pipe string and the is linked with frequency converter and controller located on surface.

摘要： A pump system for producing fluids from a reservoir using a well bore having a vertical section with a easing defining an annulus, a transitional section and a horizontal section, and a production tubing having a vertical section and a horizontal section, wherein the system includes a completion with an isolation device in the annulus near the bottom of the vertical section, a gas/liquid separator for receiving produced fluids from the horizontal section, and a vertical lift pump; a continuous flow path from the terminus of the production tubing to the vertical section; a plurality of horizontal pumps in the horizontal section, each having an intake exposed to the reservoir and an outlet in the continuous flow path. The horizontal length of the production tubing is closed to the reservoir except through the horizontal pumps. A method of producing fluids includes isolating a vertical section of a wellbore from a horizontal section; isolating the production tubing from the reservoir; pumping fluid from the reservoir adjacent a toe segment into a production tubing toe segment and towards the heel segment; and pumping fluid from the reservoir adjacent a heel segment into the production tubing heel segment and towards the vertical section, and pumping fluid up the vertical section to the surface.

摘要： A pump can include two pistons, each piston having one side exposed to a support pressure and another side exposed to a respective annular chamber, the chambers being pressurized greater than the support pressure. Fluid can be discharged from one annular chamber and received into the other annular chamber by displacement of the pistons. A method of testing a fluid can include pressurizing the fluid in response to increasing a support pressure exposed to one side of each of two pistons, thereby increasing pressure in chambers exposed to respective other sides of the pistons, and then displacing the pistons, thereby flowing the fluid through a test manifold assembly. A fluid test system can include a pump having a support pressure exposed to sides of two pistons, and another side of each of the pistons being exposed to a respective annular chamber. Each annular chamber can be connected to a sensor.

摘要： An electrical submersible pumping system (ESP) for use in pumping fluids from a wellbore. The ESP includes fins on an outer portion of the ESP that transfer heat from a motor in the ESP to fluid flowing past the fins. A self removing material is provided over the fins when the ESP is deployed into the wellbore to protect the fins against being damaged when the ESP contacts a wall of the wellbore. The material can corrode, erode, melt, dissolve, disintegrate, or otherwise automatically decouple from the fins when the ESP is disposed in the wellbore.
