Abstract
A separate layer oil production screw pump is characterized in that an upper pump body 4 is connected with a lower pump body 10 through a connecting tube 5 which has a pored tube wall and the outerwall provided with a packer 7; the lower end of the lower pump body 10 is also connected with a tail pipe 13 which has a pored tube wall and the outerwall provided with an anchor 11; an upper rotor 3 is connected with a lower rotor 9 through a connection shaft 8; moreover, the upper end of the upper rotor 3 is provided with a connecting-tripping device 2. With reasonable design, a simple structure, convenience for use and reliable operation, the utility model has better sand-protection and anti-gas functions and energy conservation effect, thereby having widespread use in separate oil production of various oil wells.
Description
Technical field:
The utility model relates to a kind of oil field downhole tool, especially for the layered oil producing screw pump of oil well.
Background technique:
Before the utility model, general oil field is for solving the screw pump that special lifting problems such as sand production are used, be used for all that individual layer recovers the oil or multilayer is mixed and adopted, because not possessing branch adopts function, so can't solve the special lifting problems such as sand production that need oil production by layer, also limit the Applicable scope of screw pump simultaneously.
Summary of the invention:
The purpose of this utility model is: for the oil field provides a kind of layered oil producing screw pump that is used for oil well, because this device has the oil production by layer function, can solve the special lifting problems such as sand production that need oil production by layer preferably, also enlarge the Applicable scope of screw pump simultaneously.
The purpose of this utility model realizes by following measure: a kind of layered oil producing screw pump, comprise disjointed device, upper rotor part, upper pump casing, packet, lower rotor part, lower pump body, anchor and tail pipe etc., it is characterized in that upper pump casing and lower pump body are to be connected by the connecting tube that tube wall belt hole, pipe outer wall are equipped with packet, and the lower pump body lower end also connects the tail pipe that a tube wall belt hole, pipe outer wall are equipped with anchor; Be to be connected between the upper rotor part of corresponding installation and the lower rotor part in upper pump casing and the lower pump body, and the upper rotor part upper end also is equipped with a disjointed device by shaft-like coupling shaft.
The utility model is reasonable in design, simple in structure, easy to use, reliable operation, has sand control, anti-airway dysfunction and energy-saving effect preferably, and the branch that can be widely used in all kinds of oil wells is adopted operation.
Description of drawings:
Fig. 1 is the structural representation of layered oil producing screw pump.
Embodiment:
As shown in Figure 1, layered oil producing screw pump is made up of disjointed device 2, upper rotor part 3, upper pump casing 4, connecting tube 5, packet 7, coupling shaft 8, lower rotor part 9, lower pump body 10, anchor 11 and tail pipe 13 etc.
Upper pump casing 4 and lower pump body 10 are to be connected by the connecting tube 5 that tube wall belt hole, pipe outer wall are equipped with packet 7, and lower pump body 10 lower ends also connect the tail pipe 13 that a tube wall belt hole, pipe outer wall are equipped with anchor 11; Be to be connected between the upper rotor part 3 of corresponding installations and the lower rotor part 9 in upper pump casing 4 and the lower pump body 10, and upper rotor part 3 upper ends also are equipped with a disjointed device 2 by shaft-like coupling shaft 8.
The working principle and the using method of layered oil producing screw pump are: with the layered oil producing screw pump that assembles by upper pump casing 4 with incorporate the precalculated position, down-hole under tubing string 1 is connected, discharge packet 7 and anchor 11 and make it all in running order; Be lowered to the beam hanger post again in tubing string 1, and be connected with upper rotor part by disjointed device 2, just can start rotation beam hanger post and drive upper rotor part 3, lower rotor part 9 rotation works this moment on ground.After layered oil producing screw pump entered working state, the output liquid of bottom oil reservoir 12 can enter lower pump body 10 by tail pipe 13, entered in the tubing string 1 after the pumping by lower rotor part 9 and upper rotor part 3 again; The output liquid of top oil reservoir 6 then directly enters upper pump casing 4 by connecting tube 5, and enters in the tubing string 1 after the pumping by upper rotor part 3.Layered oil producing screw pump when work, because the sealing process of packet 7 and lower pump body 10, avoided the mutual interference mutually between top oil reservoir 6 and the bottom oil reservoir 12, thereby realized the purpose of oil production by layer.
