Abstract
The invention provides an integrated well cleaning and sand controlling technology string, comprising an upper ball valve and a suspending mechanism, a lower adapter, a collar, a sand-controlling screen, a flushing pipe, a centralizer, a connecting sleeve, a sealing body, a seal plug, a well cleaning valve and a plug, the upper ball valve comprises a valve body as well as the upper valve ball, a hole ball board, an upper spring and a plug arranged in the valve body, the well cleaning valve comprises a well cleaning valve body and a lower spring, a spring seat and a lower valve ball arranged in the well valve body, the upper valve ball and the suspending mechanism are connected with the lower adapter, the collar, the sand-controlling screen, the connecting sleeve, the well cleaning valve body and the plug below in sequence outwards, and are connected with the flushing pipe, the centralizer and the sealing plug of the well cleaning valve in sequence inwards; the sealing body is arrangedbetween the seal plug and the well cleaning valve body; the lower valve ball, the lower spring and the spring seat are arranged under the sealing plug in sequence. The technology string has double functions of sand controlling and well cleaning, can be widely applied in sand-controlling technology of oil exploitation.
Description
One, technical field
The present invention relates to oil exploitation underground work tubing string, particularly a kind of well-washing sand prevention integrated technique tubular pile.
Two, background technology
Traditional well-flushing sand control pipe finds to exist following shortcoming or deficiency in job execution: 1. the sand control treatment tubing string does not have the well-flushing function, need other Flushing tubular column down during well-flushing, cause construction operation complicated, both wastes of manpower, material resources, financial resources prolong the activity duration again; 2. especially in shake out serious horizontal well, high angle hole, when being lowered to big latus rectum screen casing, sand plug, sand card phenomenon often take place, make sand control pipe be difficult to put in place smoothly, even cause damage, give up midway until fishing to sand control pipe, increase task difficulty, improved operating cost.
Three, summary of the invention
The purpose of this invention is to provide a kind of improved well-washing sand prevention integrated technique tubular pile, employing is provided with a cover well washing apparatus and the automatic positioning mechanism and the system of giving up in the sand control screen bottom, both had the well-flushing function, what guarantee to give up piston and washing pipe again removes the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art smoothly.
Well-washing sand prevention integrated technique tubular pile of the present invention, comprise upper ball valve and hitch, lower contact, box cupling, sand control screen, washing pipe, centralizer, adapter sleeve, seal, sealing plug, flushing valve and plug, described upper ball valve comprises the upper valve ball of valve body and interior installation thereof, ball plate with holes, upper spring and plug, described flushing valve comprises the lower spring of well-flushing valve body and interior installation thereof, spring base and lower valve ball, described upper valve ball and hitch down outer in turn with lower contact, box cupling, sand control screen, adapter sleeve, the well-flushing valve body is connected with plug, in in turn with washing pipe, centralizer is connected with sealing plug, between sealing plug and the well-flushing valve body seal being installed, is lower valve ball in turn under the sealing plug, lower spring and spring base.
Wherein, on the valve body on the described upper spring plug is installed.Described hitch and valve body are fixed by pin.Described sealing plug bottom is provided with through hole.Described well-flushing valve body top was provided with opening, and this is crossed opening and is connected with the through hole of sealing plug.Be provided with annular space between described washing pipe and the sand control screen, centralizer is installed therebetween.
The present invention has the following advantages compared with prior art:
1, well-flushing and sand control pipe integrated design had both had the sand control function, had the well-flushing function again.
2, design automatic positioning mechanism, the unlatching effect of assurance flushing valve.
3, optimal design releasing gadget guarantees that tubing string removes smoothly.
Four, description of drawings: accompanying drawing is a kind of structural representation of the present invention.
Five, the specific embodiment
Consult accompanying drawing, a kind of well-washing sand prevention integrated technique tubular pile, comprise upper ball valve and hitch, lower contact, box cupling, sand control screen, washing pipe, centralizer, adapter sleeve, seal, sealing plug, flushing valve and plug, upper ball valve comprises the upper valve ball 5 of valve body 7 and interior installation thereof, ball plate 4 with holes, upper spring 3 and plug 1, flushing valve comprises the lower spring 17 of well-flushing valve body 16 and interior installation thereof, spring base 18 and lower valve ball 15, upper valve ball 5 and hitch 2 times outward in turn with lower contact 6, box cupling 8, sand control screen 9, adapter sleeve 12, well-flushing valve body 16 is connected with plug 19, in in turn with washing pipe 10, centralizer 11 is connected with sealing plug 14, between sealing plug 14 and the well-flushing valve body 16 seal 13 is installed, sealing plug is for 14 times lower valve ball 15 in turn, lower spring 17 and spring base 18.
On the valve body 7 of upper spring 3 upper ends plug 1 is installed.Hitch 2 is fixed by pin 21 with valve body 7.Sealing plug 14 bottoms are provided with through hole 20.Well-flushing valve body 16 tops were provided with opening 20, and this is crossed opening and is connected with the through hole of sealing plug.Be provided with annular space between washing pipe 10 and the sand control screen 9, centralizer 11 is installed therebetween.
