Detailed description of the invention
For the technical characterstic of this programme can be clearly demonstrated, below by a detailed description of the invention, and in conjunction with its accompanying drawing, this programme is set forth.
As can be seen from Fig. 1 and 2: the lining of the present invention on gravel pack tools, it is characterized in that: it comprises the lining sliding sleeve 308, sliding sleeve urceolus 314, the positioning pipe 309 that connect in turn from the inside to the outside, sliding sleeve urceolus 314 lower end is connected with shearing ring 315, shearing ring 315 is provided with shear pin 310, the lower end of shear pin 310 is fixedly connected on lining sliding sleeve 308; Positioning pipe 309 lower end is connected with fixture block 300, and positioning pipe 309 upper end is connected with location lock dog 302, and location lock dog 302 is connected with positioning tube 306; Described lining sliding sleeve 308 is provided with the groove matched with described fixture block 300.Spring 305 is fixedly connected with inside positioning pipe 309; Positioning tube 306 is provided with the location locked groove holding location lock dog 302; The lower end of positioning pipe 309 is provided with positioning step, and positioning step is connected with fixture block 300.Lock dog retainer 313 is provided with between positioning pipe 309 and location lock dog 302; Spring 305 upper end is connected with back-up ring 319, and back-up ring 319 other end is connected with positioning tube 306.
The lining of the present invention on gravel pack tools, positioning tube 306 is connected with sand control ring support 312, sand control ring support 312 is provided with sand prevention ring 318; Sand control ring support 312 upper end is connected with top connection 311, is provided with inner seal liner 301 in top connection 311; Sliding sleeve urceolus 314 is connected with guide shoe 304 by sealing cylinder base 316, and sealing cylinder base 316 is provided with joint ring 303.
The lining of the present invention on gravel pack tools, when assembling, lining and seal with buss cylinder are assembled together, and now locate lock dog 302 and match with the groove 23 of top connection 21 inner chamber of seal with buss cylinder, location lock dog 302 blocks groove 23, realizes the locking of lining; Fashionable under outer tubing string, lining along with seal with buss cylinder outside tubing string enter up and down, and then under enter service aid.
The lining of the present invention on gravel pack tools coordinates with seal with buss cylinder, can realize the interior external seal of gravel pack tools.A circulation annular space is provided with between service aid and outer tubing string, washing pipe on service aid and be provided with a circulation annular space between central tube, now, the joint ring 303 of lining seals with lower contact 22 phase of the seal with buss cylinder on outer tubing string, the inner seal liner 301 of lining seals mutually with the washing pipe on service aid, ensure in whole stowing operation, the isolation on sleeve pipe (space between outer tubing string and service aid) annular space and stratum.The lining of the present invention on gravel pack tools coordinates with seal with buss cylinder, and backwash liquor when returning fluid when can also prevent filling and anti-flushing well enters stratum, avoids stratum to be polluted.
When carrying out gravel pack middle level and bottom, lining will be locked, coordinate with seal with buss cylinder the effect playing interior external seal, state is at this moment: location lock dog 302 matches with the groove 23 of top connection 21 inner chamber of seal with buss cylinder, location lock dog 302 blocks groove 23, realizes the locking of lining.
The lining of the present invention on gravel pack tools reclaims state: be exactly after all sand control treatments terminate, opened out by service aid, now also by lining along with service aid opens out, will be stayed in well by outer tubing string.At this moment need lining to reclaim that is lining and seal with buss cylinder to be departed from: above carry service aid, filling crossover tool on service aid is carried to lining, the Special threading connector 155 recovery boss 157 be positioned on filling crossover tool tangles the step on lining sliding sleeve 308, under the effect of upper lifting force, shear pin 310 on shearing ring 315 is cut off, now lining sliding sleeve 308 is carried with on filling crossover tool, lining sliding sleeve 308 moves upward relative to sliding sleeve urceolus 314, fixture block 300 is made to fall in the groove of lining sliding sleeve 308, fixture block 300 blocks the positioning step of incessantly positioning pipe 309, positioning pipe 309 loses the support of fixture block 300.Spring 305 promotes positioning pipe 309 and moves downward relative to sliding sleeve urceolus 314, sliding sleeve urceolus 314 drives lock dog retainer 313 fixture block retainer 313 to be threaded with positioning pipe 309, both move together and move downward, lock dog retainer 313 drives location lock dog 302 to move downward simultaneously, location lock dog 302 is made to fall in the groove of positioning tube 306, now, location lock dog 302 blocks the groove 23 of incessantly seal with buss cylinder, lining and seal with buss cylinder depart from, lining opens out with service aid, realizes the recovery of lining.
