Detailed description of the invention
As shown in Figure 1, tubing string water booster system of the present invention is made up of Fang Shangding mechanism, hydraulic cylinder assembly and anti-reverse mechanism, and Fang Shangding mechanism is primarily of the flange 10 of slotting with L shape and locking component composition, and locking component has 4, fluting flange 10 is evenly arranged, and its main body is trapezoid seat 6.Trapezoid seat 6 inner vertical direction is provided with the oblique hole that cross section is rectangle, the oblique of hole is from bottom to up gradually near entering well casing post 17, loads roller bearing 1, spring I 5 successively, and block with block 7 in hole.Roller bearing 1 close to enter well casing post 17 time expose from trapezoid seat 6, after in-site installation, roller bearing 1 can be adjacent under spring force into well casing post 17, when entering the relative lockable mechanism of well casing post 17 and producing upwards generation displacement, roller bearing 1 can be driven upwards to rotate, and under the effect of trapezoid seat 6 inclined hole medial surface, roller bearing 1 inwardly heads into well casing post 17 diametrically, until locking enters well casing post 17, prevent into well casing post 17 to top offset.
Hydraulic cylinder assembly is the power source of tubing string water booster system, by end cap 13, sealing ring 12, cylinder body 16, piston 18, sealing ring 19, fluid cylinder flange 21, bend pipe 11, valve 14 and hydraulic pump adapter 15 form, wherein piston 18 and fluting flange 10 are fixedly connected, when injecting highly pressurised liquid in hydraulic cylinder, piston 18 can drive Fang Shangding mechanism to move down, and feeds well casing post 17 and pressurizes downwards.
The effect of anti-reverse mechanism prevents from reversely rotating into well casing post 17, and its main body is rotary handle 25, and its one end is enclosed within locating shaft 24, can rotate around locating shaft.Locating shaft 24 upper end embeds in fluid cylinder flange 21, and lower end embeds in base flange 23.They have 3 respectively, are distributed on around well casing post.
Rotary handle 25 is provided with lateral aperture, in hole, loads steel ball 26, spring III 27 successively, and with plug 28 shutoff.The track in hole makes steel ball 26 gradually near entering well casing post 17 under spring III 27 promotes, and hole is being incomplete near entering a section of well casing post, and object makes steel ball 26 expose rotary handle 25 gradually, and with enter well casing post 17 and contact.
When entering well casing post 17 and reversely rotating, drive steel ball 26 to roll, under the effect of rotary handle 25 lateral aperture inner headed face, steel ball 26 holds out against diametrically into well casing post 17, prevents and reversely rotates into well casing post.
The bottom of trapezoid seat 6 is J-shaped rod-like structure, and J-shaped bar has radial blind holes K.
Fluting flange 10 is processed with L shape groove along the cylindrical tangential direction entering well casing post 17, and the J-shaped bar of the bottom of trapezoid seat 6 can be installed in L shape groove; The radial hole of level is provided with in fluting flange 10, lead in L shape groove from the outer circumference surface of flange, in-built backstay 8 and spring II 9, spring II 9 gives backstay 8 to the thrust of flange center, backstay embeds in the blind hole K of J-shaped bar, and trapezoid seat 6 is fixed on fluting flange 10.
Rotary handle 25 is fixedly connected with auxiliary rod 30, when rotary handle 25 is covered by fluid cylinder flange 21, pulls auxiliary rod 30 that rotary handle 25 can be made to rotate around locating shaft 24.
Wedge 31 top is wedge shape, and bottom is square, and is provided with screwed hole.
In base flange 23, be provided with the oblique hole of level, in-built pull bar 32 and spring IV 33, pull bar 32 end is processed with screw thread.End in oblique hole, vertical flange face are processed with square opening, and the inside embeds the projected square part of wedge 31, the thread connection of the screwed hole in projected square part and pull bar 32 end.In its natural state, under the promotion of spring IV 33, wedge 31 is in inner dead centre position.
In base flange 23, being radially processed with screwed hole, in-built jackscrew 29, can holding out against with entering well casing post 17.
Tubing string water booster system is when well head is installed, the locking component of Fang Shangding mechanism, as shown in Figure 3, first be not installed on fluting flange 10, anti-reverse mechanism is in release conditions, as shown in accompanying drawing 2 (b), hydraulic cylinder piston 18 is when lower dead point position, valve-off 14, hydraulic cylinder chamber is airtight, just can not produce displacement between hydraulic cylinder piston 18 and cylinder body 16.
The tubing string 17 that last root will be entered well passes in the middle of water booster system, inside rotation jackscrew 29, with enter well casing post 17 and hold out against, then be installed lockable mechanism: first upwardly compressing tablet 4, make it overcome torsionspring 3 elastic force, rotate around bearing pin 2, to lower press rolls axle 1, in the inclined hole of roller bearing 1 indentation trapezoid seat 6, so that trapezoid seat 6 is installed on fluting flange 10, as shown in Figure 1.
Rise and hang in well casing post 17 with tubing string water booster system to well head, after oil pipe is linked, lower drain line, makes the flange of tubing string water booster system and wellhead blowout preventor align, and connects with bolt 22, then unclamp jackscrew 29.
When oil pipe arrives precalculated position 17 times, promote auxiliary rod 30, rotary handle 25 is inwardly rotated, when encountering the inclined-plane of wedge 31, promote wedge 31 outwards to move back, when rotary handle 25 turns over wedge 31 completely, wedge 31 can move inward under the effect of spring IV 33, thus prevents rotary handle 25 outwards to turn round.After three rotary handles all inwardly rotate in place, its state, as shown in accompanying drawing 2 (a), just can realize stoping reversely rotating into well casing post 17.
Hydraulic pump adapter 15 is connected with hydraulic pump pipeline outlet, unclamp valve 14, on carry into well casing post 17, due to the unidirectional locking function of Fang Shangding mechanism, enter well casing post 17 can drive on Fang Shangding mechanism and piston 18 and move, when piston 18 moves to close to upper dead center position, valve-off 14, well casing post 17 is put into slowly, when drill bit arrives precalculated position, open valve 14, primer fluid press pump, suppress in the fluid cylinder of tubing string water booster system, hydraulic drive piston 18, drive Fang Shangding mechanism feed well casing post 17 and apply downward thrust.
After hydraulic cylinder covers a stroke, close hydraulic pump, repeat above-mentioned: above carry well casing post 17, valve-off 14, slowly under put into well casing post 17, open valve 14, the step such as primer fluid press pump is suppressed, realize creeping into continuously.
When enter well casing post 17 has box cupling will locking component through Fang Shangding mechanism time, then to take off the locking component of Fang Shangding mechanism, adjust up and down into well casing post 17, make box cupling pass locking component, and reinstall locking component; When box cupling will pass anti-reverse mechanism, then first pull out pull bar 32, drive wedge 31 outwards movement, then pull auxiliary rod 30, make rotary handle 25 to inner rotary, release anti-reverse mechanism, position between adjustment anti-reverse mechanism and box cupling, box cupling, through after anti-reverse mechanism, makes anti-reverse mechanism relock into well casing post 17, like this when drilling distance is longer, do not need dismounting tubing string water booster system can realize creeping into continuously yet.
