In example, the axis of nozzle 9 and playpipe 1 is vertically arranged.
The use of the abrasive perforating instrument refers to following steps：
1), when abrasive perforating instrument in use, one end of its one end and tubing string is connected first, such as by the first righting
Joint 51 is connected with tubing string, the other end connection ground abrasive blast equipment of tubing string.
2) after, instrument is by oil pipe tripping in place, enter before horizontal well, ground abrasive blast equipment is not turned on, without pressure fluid
Into the sand perforation tool.When first hollow rotating shaft component 2 and the second hollow rotating shaft component 3 are in first position.This first
Put in finger, the first hollow rotating shaft component 2 and the second hollow rotating shaft component 3 and close in playpipe 1, on each hollow rotating shaft 4
Two sealing rings 72 are not entered into respective adapter sleeve 6, can freely be rotated between upper and lower joint, are entered during well, are relied on
Gravity eccentricity principle, playpipe 1 is turned to vertically upwardly-directed, so as to realize automatic upwardly-directed.
3), tubing string in place after, the abrasive perforating instrument is in horizontality, and adjustment tubing string length is to ensure that nozzle 9 is just right
Spray well section；The pump pressure of ground abrasive blast equipment gradually rises during construction, and tubing string internal pressure power acts on the end face of two hollow rotating shafts 4
On, promote the first hollow rotating shaft component 2 and the second hollow rotating shaft component 3 of the both sides of playpipe 1 to be respectively facing away from playpipe 1
Direction is slided until the second sealing ring 72 is slipped into corresponding adapter sleeve 6.Now, the first hollow rotating shaft component 2 and second is hollow
Rotating assembly 3 is in the second place, and each second sealing ring 72 is squeezed between each self-corresponding adapter sleeve 6 and hollow rotating shaft 4,
It is mutually stuck sealed between first hollow rotating shaft component 2 and the second hollow rotating shaft component 3 and playpipe 1, it is impossible to realize relative fortune
It is dynamic.Pressure fluid thrust keeps realizing Y type sealing functions between playpipe 1 and two hollow rotating shafts 4.
4) after, first paragraph construction terminates, pump pressure falls zero, and thrust disappears, between playpipe 1 and two components of hollow rotating shaft 4
Y types sealing function disappear.Occurs phase due to being acted on without seal friction force between playpipe 1 and two components of hollow rotating shaft 4
To rotating, affranchise rotary state again each other.Tubing string can now be carried to the second jet segment, above-mentioned action is repeated,
Complete to orient abrasive perforating construction on a well multistage.
The abrasive perforating instrument, the instrument of realizing locks when entering underground automatic orientation after well, construction and terminates extensive after construction
The three zones oriented again.
The abrasive perforating instrument can be applied to horizontal well later development, due to oil reservoir yield reduction, aqueous rise even water
The problems such as flooding.The abrasive perforating instrument can meet in horizontal well perforating and fracturing only up, it is ensured that lower wellbore is intact, stores up bottom
Oil only flows into pit shaft, and bottom bottom is not scurried into, improves recovery ratio, and avoids bottom bottom water outlet, reduces water rate.
In addition, the abrasive perforating instrument can be applied to the Oil/gas Well of nearly all abrasive perforating operation, at home and abroad have
Extremely wide application prospect.
