Further, it is fixedly installed hydraulic anchoring device at the top of screw pump, crosses the lower part that pump installation is located at hydraulic anchoring device.
Further, the lower contact for crossing pump installation bottom end is the guide head of back taper, and the second centralizer is located at guide head, outside
Edge is fixed on the internal face of casing, is swung for preventing pump installation and crossing the lengthening oil pipe of pump installation bottom, to ensure
The both ends of pump installation are in stationary state.
Further, the bottom of the second centralizer is connected with oil pipe is lengthened, to improve the mixture effect of dilute viscous crude.
Further, the bottom for lengthening oil pipe is connected by screen casing with sedimentation pipe, by screen casing to prevent viscous crude block from entering
In screw pump.
The advantages of mixture tubing string, is under a kind of pump of submersible screw pump of the utility model：
1) it is suitable for mixing dilute or mixes chemical agent etc. and carry out the submersible screw pump of viscosity reduction and need to be promoted the oil of mixture effect
In well；
2) it changes pump under the conditions of the prior art to hang and to mix dilute mixture point co-located, passes through mistake pump installation and lengthening
Oil pipe realizes that pump is hung and mixes dilute mixture point phase separation, and pump, which is hung, is located at 2000m, and 4000m can be reached deeply under oil pipe by lengthening, and be improved
The effect of dilute viscous crude mixture, reduces thin oil dosage；
3) the mixture effect for improving the dilute viscous crude of submersible screw pump, the depth for mixing dilute mixture point are promoted to by 2000m
4000m, temperature increase 40 DEG C, effectively increase dilute viscous crude mixture effect, reduce thin oil dosage, reduce Anomalies of Oil Wells, improve
Operating condition.
Description of the drawings
Fig. 1 is that the screw pump of the utility model installed the structural schematic diagram before pump installation；
Fig. 2 is that the screw pump of the utility model installed the structural schematic diagram after pump installation.
Specific implementation mode
In order to be better understood by the purpose of this utility model, structure and function, below in conjunction with the accompanying drawings, to the utility model
Mixture tubing string does further detailed description under a kind of pump of submersible screw pump.
As shown in Fig. 2, it is shown as mixture tubing string under a kind of pump of submersible screw pump of the utility model, it is set in casing 1
It between screw pump 5, including crosses pump installation 4 and lengthens oil pipe 10, the top for crossing pump installation 4 is connected with upper oil pipe, crosses pump dress
It includes top connection, small casing and the lower contact for from top to bottom connecting setting successively, internal thread and the screw rod pump assembly of top connection to set 4
It is connected, lengthens oil pipe 10 and be connected with the bottom for crossing pump installation 4 by lower contact, by the lengthening oil pipe 10 of long range to real
Now deepen to mix dilute mixture point, improves mixture effect.
Further, since the vibration of screw pump 5 at runtime is larger, in order to reduce the Oscillation Amplitude of screw pump 5, screw pump
5 top is fixedly installed hydraulic anchoring device 2, i.e., pump installation 4 be located at the lower part of hydraulic anchoring device 2.
Further, the top interior for crossing pump installation 4 is fixedly installed the first centralizer 6, to prevent from terminating on pump installation 4
Screw rod pump assembly inside head is swung.
Further, it crosses in pump installation 4 and is provided with protector 8, motor, to realize the purpose of unit not load-bearing.
Further, the lower contact for crossing 4 bottom end of pump installation is the guide head of back taper, and the second centralizer 9 is located at guide head,
The outer rim of second centralizer 9 is fixed on the internal face of casing 1, for preventing pump installation 4 and crossing the lengthening of 4 bottom of pump installation
