Abstract

The invention belongs to the field of tertiary recovery oil recovery in oil field oil recovery engineering, and relates to a novel electric pressure measuring and regulating device for a chemical flooding separate injection well. The device is designed aiming at the problems of repeated throwing and fishing, higher testing labor intensity, lower working efficiency and the like, and consists of an adjusting rod 1, a spring 2, an O-shaped sealing ring 3, a sliding outer sleeve 4, a main body outer sleeve 5, a plug 6, an adjusting element 7, a stop lever 8, an anti-falling bottom plug 9 and a lower connector 10; the invention is mainly applied to the measurement and adjustment of the chemical flooding separate injection well, and has the advantages of simple structure, light weight, convenient use, reduced construction strength, high measurement and adjustment efficiency and the like.

Description

A kind of chemical flooding divides annotates well electric survey pressure regulation apparatus for adjusting force
Technical field: the invention belongs to oil field petroleum production engineering three oil recovery fields, is that a kind of chemical flooding divides the notes well to survey the pressure regulation apparatus for adjusting force with electric.
Background technology: at present, chemical flooding branch matter dividing potential drop injection technique is to control the injection pressure of each interval through the length of regulating injection allocation core in the eccentric injection allocation device, controls the injection rate of each interval chemical flooding solution, thereby realizes the dividing potential drop injection.Because chemical flooding divides notes well adjustment layering injection rate to need tentative pulling blanking plug; Change throttling components and parts pulling blanking plug repeatedly; Pulling out to assemble in the next blanking plug duct has impurity, to next pulling formation obstacle, therefore exists problems such as test labour intensity is big, survey accent efficient is lower.
Summary of the invention: the objective of the invention is to exist and change throttling components and parts pulling blanking plug repeatedly to above-mentioned existing device; Test problems such as labour intensity is bigger and design need not repeat pulling; And the reduction construction intensity improves to survey and transfers a kind of chemical flooding branch notes well electric of efficient to survey the pressure regulation apparatus for adjusting force.
The present invention mainly is made up of stifled at the bottom of adjusting rod, spring, " O " RunddichtringO, sliding outer cover, main body overcoat, plug, regulating element, pin, the anticreep and lower contact; The mode of adjusting rod through screw thread is connected with sliding outer cover; Pin passes from the centre bore of regulating element, and spring housing is contained on the pin, and pin is through the mode of welding and stifled connection the at the bottom of the anticreep; Plug is installed to the upper end of regulating element; And be connected with regulating element through the mode of welding, regulating element and sliding outer cover are connected through the mode of welding, and " O " RunddichtringO is sleeved on the sliding outer cover; With blocking up integral assembling at the bottom of adjusting rod, spring, " O " RunddichtringO, sliding outer cover, plug, regulating element, pin, the anticreep in the main body overcoat; Suit in main body overcoat and the lower contact " O " RunddichtringO, the main body overcoat is connected through screw thread with lower contact, and seals through " O " RunddichtringO.
Regulating element is annular relief groove structure, and the number of annular relief groove is 7.
The present invention compared with prior art has following advantage:
(1), need not repeat pulling; And reduced construction intensity, shortened the engineering time, improved to survey and transferred efficient.
(2), the throttling components and parts be difficult for to stop up, and are and simple in structure, in light weight, easy to use.
Description of drawings: Fig. 1 is a structural representation of the present invention.
The specific embodiment: the present invention is made further explanation below in conjunction with accompanying drawing: the present invention by adjusting rod 1, spring 2, " O " RunddichtringO 3, sliding outer cover 4, main body overcoat 5, plug 6, regulating element 7, pin 8, anticreep at the bottom of stifled 9 and lower contact 10 form; The mode of adjusting rod 1 through screw thread is connected with sliding outer cover 4; Pin 8 passes from the centre bore of regulating element 7, and spring 2 is sleeved on the pin 8, pin 8 through the mode of welding with block up 9 at the bottom of the anticreep and be connected; Plug 6 is installed to the upper end of regulating element 7; And be connected with regulating element 7 through the mode of welding, regulating element 7 and sliding outer cover 4 are connected through the mode of welding, and " O " RunddichtringO 3 is sleeved on the sliding outer cover 4; With blocking up 9 integral assemblings at the bottom of adjusting rod 1, spring 2, " O " RunddichtringO 3, sliding outer cover 4, plug 6, regulating element 7, pin 8, the anticreep in main body overcoat 5; Suit " O " RunddichtringO 3 in main body overcoat 5 and the lower contact 10, main body overcoat 5 and lower contact 10 are connected through screw thread, and seal through " O " RunddichtringO 3.
Regulating element 7 is annular relief groove structure, and the number of annular relief groove is 7.
During The field; At first utilize throw in catcher to arrive predetermined level to the present invention down, drive sliding outer cover 4 through rotation adjusting bar 1 and in main body overcoat 5, slide, after polymer solution gets into from inlet opening B with regulating element 7; Flow through behind the regulating element 7, after fluid hole A flows out, enter into the stratum.
