Abstract
The utility model relates to an electric submersible screw pump which comprises a screw pump and a motor. The utility model is characterized in that a submersible motor is arranged in an oil pipe; a rotor of the screw pump is directly connected with a motor shaft; the motor is connected with a power supply on the ground by a cable arranged outside the oil pipe. The submersible motor which can work in the oil is adopted and the submersible motor is directly arranged underground and connected with the rotor of the screw pump, the utility model saves a sucker rod; therefore, the utility model can save the electricity, and provides conditions for the wide application in deep oil wells, scaling wells and heavy oil wells.
Description
One, technical field: the utility model relates to a kind of oil production equipment, particularly a kind of electric oil submerged screw pump.
Two, background technique: the screw pump oil production technology is used already, because the motor of drive screw pump is located on the well head on ground, by the sucker rod transferring power, when oil well is more shallow, has lot of advantages between motor and the pump, but, when oil well was dark, motor need drive very long sucker rod, and energy consumption is also big, the easy bending deflection of sucker rod, rupture and come off, in addition, it is not suitable for sand drain, thick oil well, fouling well etc., and its service condition is restricted.
Three, summary of the invention: technical problem to be solved in the utility model is, motor is arranged on the down-hole directly is connected with screw pump, overcomes above-mentioned shortcoming.The technical solution of the utility model is such, and it includes screw pump and motor, it is characterized in that: oil-submersible motor is located in the oil pipe, and the rotor of screw pump directly is connected with motor shaft, and motor is connected by being located at the outer cable of oil pipe with ground power supply.The utility model has been owing to adopted the oil-submersible motor that can work in oil, oil-submersible motor is directly arranged in the down-hole and is connected with the rotor of screw pump, so compare with existing screw pump oil pumping, has energy-conservation and the wide remarkable advantage of using scope.
Four, description of drawings: Fig. 1 is an electric oil submerged screw pump structural representation of the present utility model.Among the figure, 1. oil pipe 2. screen casings 3. screw pumps 4. tubing centrilizers 5. oil-submersible motors 6. cables
Five, embodiment: the lower end of screw pump 3 is connected on the screen casing 2, the rotor of screw pump 3 is connected with the axle of oil-submersible motor 5, the oil pipe 1 outer cable 6 that is provided with, its two ends are connected with ground power supply with oil-submersible motor respectively, and oil pipe 1 is supported in the oil well by tubing centrilizer 4 and makes it to keep vertical state.The difference of the utility model and existing screw pump is that the motor that is adopted is an oil-submersible motor, and cable is an oil-submersible cable, no longer connects part by sucker rod between motor and the screw pump, and its working principle is identical.
