Specific embodiment
Embodiment 1：
As shown in figure 1, present embodiments providing a kind of horizontal well every tubing string, including oil pipe 18 is adopted, the oil pipe 18 is under
And on be connected to be oriented to plug 20, screen casing 21, packer 22, every adopting switching valve 19 and oil well pump 24.
Horizontal well every the operation principle and the course of work for adopting tubing string is：
Conscientiously check before lower brill shown in accompanying drawing 2 every adopting switching valve 19, it is ensured that through-flow in master shown in Fig. 2 every switching valve 19 is adopted
Road is unimpeded, the state that bypass flow channel is closed, lower after the good tool string that is correctly linked in sequence to bore, when packer 22 be lowered into it is estimated every
When adopting position, tubing string operation set packer 22 is put by above putting, horizontal well production section artificial is divided into into upper and lower two portions
Point.Now, by automatic drain or oil well pump pumping discharge opeing, the liquid-liquid Jing screen casing of the simply packer bottom interval of output
After 21 filter, by the interior latus rectum of packer 22, it is then passed through every the main passage flow duct for adopting switching valve 19, finally inside oil pipe 18
It is discharged to ground.After the Fluid Producing Property of 22 bottom of correct understanding packer, in the case of fixed tubular column, can be by pitching in pipe
The mode for building the pressure starts shown in accompanying drawing 3 every the sliding sleeve 8 for adopting switching valve 19 so that every main passage flow duct closing, the side of adopting switching valve 19
Passage flow duct opens state shown in accompanying drawing 3, has thus quickly blocked the passage that 22 lower liquid of packer is flowed in oil pipe 18,
Ensuing automatic drain or pumping discharge opeing, discharge is that the 22 top interval of product liquid packer of 22 top interval of packer produces liquid
Flow through every the bypass flow channel for adopting switching valve 19, into inside oil pipe 18, ground is discharged along oil pipe 18.By above-mentioned technique side
Method, in the case of fixed tubular column, is only built the pressure operation by pitching in pipe, you can sealing up for process pipe string is adopted lower work(quickly
Can be converted under envelope, adopting function, operation is efficiently simple.
It should be noted that it is all existing ripe well to be wherein oriented to plug 20, screen casing 21, packer 22, oil well pump 24
Lower instrument, concrete structure do not do especially narration, and the oil pipe 18 that oil pipe string is used is also the conventional oil pipe that recovers the oil, only every adopting conversion
Valve 19 is the newly-designed instrument of this utility model.The function and usage of the ripe instrument matched in this is to process pipe string is simply situated between
Continue：1. the effect for being oriented to plug 20 is plugging tubing string bottom, and plays a part of to be oriented to introducing in going down process；2. screen casing
21 is the necessary channel that 22 bottom liquid stream of packer is entered in pipe, while the large granular impurity in filtrate stream, prevents bulky grain
Impurity is entered in pipe, is affected every the normal work for adopting switching valve 19 or oil well pump 24；3. packer be a one-way slip support,
On put the compression packer for putting that tubing string sets, unseals, play packer oil jacket annular space after setting, packer 22 it is interior
Latus rectum remains unimpeded；4. oil well pump 24 be used for stratum energy it is not enough when, liquid be when cannot be flowed up by the interior blowing of pipe
Pumping discharge opeing instrument, its wheel cylinder shell and pump core two large divisions will enter pump case, ground oil pumper under pump core when needing pumping discharge opeing
The lower work discharge opeing of effect, it is not necessary to pump core is can be taken off during pumping discharge opeing, makes latus rectum in tubing string keep unimpeded.
Embodiment 2：
On the basis of embodiment 1, as shown in Figures 2 and 3, it is described every adopting switching valve 19 from top to bottom by top connection 1, shell
Body 2, lower contact 15 are sequentially connected composition；2 upper inside wall of the housing is provided with two undergauge steps, in first undergauge step 17
Grommet 3 is provided with, C-shaped lock ring 5 in second undergauge step 23, is provided with, C-shaped lock ring 5 is located at below grommet 3,2 middle part barrel of housing
On offer housing by-pass prot 9；Sliding sleeve 8 is provided with the housing 2, the outer wall of sliding sleeve 8 is connected with housing 2 by shear pin 10, it is sliding
The external wall of upper portion of set 8 is provided with sawtooth 11, and middle part outer wall offers sliding sleeve by-pass prot 6, and bottom outer wall offers the main passage flow duct of sliding sleeve
Side opening 12, the lowermost end of sliding sleeve 8 is blind plugging；The inwall of the lower contact 15 is provided with sealing member 4.
It is as follows every the operation principle for adopting switching valve 19：
Every 19 times brill states of switching valve are adopted as shown in Figure 2, sliding sleeve 8 is fixed on above housing 2 by shear pin 10, housing bypass
The sealing mechanism sealing that hole 9 is constituted by sliding sleeve 8 and the O-ring seals 7 above which, is connect from above every the main passage flow duct for adopting switching valve 19
Latus rectum, the main passage flow duct side opening 12 of sliding sleeve, 13 endoporus of pressure cap, 14 endoporus of v-seal packing group, lower contact in 1 endoporus, sliding sleeve 8
15 endoporus are constituted；Every adopting in the coincidence passage of the bypass flow channel by sliding sleeve by-pass prot 6 and housing by-pass prot 9 of switching valve, sliding sleeve 8
Latus rectum, the endoporus composition of top connection 1.
Such as Fig. 2, in the case where sliding sleeve 8 is fixed by shear pin 10, it is unimpeded every the main passage flow duct for adopting switching valve 19, needs
Runner change when, as shown in figure 3, by pipe in deliver steel ball 16, when steel ball 16 is seated in 8 upper end of sliding sleeve, build the pressure generation to
Under thrust, first cut off the shear pin 10 of fixed sliding sleeve under down thrust effect, then sliding sleeve 8 is moved down, until the lower end of sliding sleeve 8 it is blind
The endoporus of the fully-inserted v-seal packing group in stifled part 14,8 upper end of sliding sleeve strut C-shaped lock ring 5 by force and are fitted completely, this
When 8 lower end of sliding sleeve will withstand on the endoporus upper surface of lower contact 15, no longer move down state now as shown in Figure 3.
Complete pitching promotion is built the pressure after the operation for adopting switching valve sliding sleeve 8, as shown in figure 3, due to 8 lower end blind plugging of sliding sleeve
Partial insertion v-seal packing group 14, this after adopting, the main passage flow duct of switching valve is no longer unimpeded to prevent liquid from lower contact 15
Endoporus flow through the endoporus of v-seal packing group 14, but due to every adopting switching valve sliding sleeve by-pass prot 6 with housing by-pass prot 9
Overlap, while opening every the bypass flow channel for adopting switching valve.Steel ball 16 can be only formed unidirectional valve action in 8 endoporus upper end of sliding sleeve,
Will not prevent liquid by every adopt switching valve bypass flow channel from oil jacket annular space flow into oil pipe in.Sliding sleeve 8 is in sliding sleeve upper end sawtooth 11
Intend to cooperate with C-shaped lock ring 5 and locked with the locking mechanism of lower composition, will not be moved up due to the bottom build-up of pressure of sliding sleeve 8.
By adopting every switching valve 19 is adopted, in the case of fixed tubular column, only built the pressure operation by pitching in pipe, you can soon
Sealing up for process pipe string is adopted lower power and energy and adopts upper function under envelope by speed, and operation is efficiently simple.
