The specific embodiment
This cable transfer secondary oriented perforation device of going into the well comprises that the first pipe string descend well operations and the second pipe to go here and there for the first time and descends for the second time well operations.
As shown in Figure 1, the first pipe string comprises top positioner 1, releasing device 3, the bottom hanging and locating device 2 that is threaded successively;
Wherein, top positioner 1 is the first torpedo 11, the first cable 12, the first head harness 13, the first magnetic orientator 14, upper centralizer 15, gyroscope 16, lower centralizer 17, the upper positioning key 18 that connects successively.
Bottom hanging and locating device 2 comprises connection successively lower positioning key 21, fishing head 22 and hanger 23.
As shown in Figure 3, releasing device 3 comprises upper bush 31, middle sleeve 32, plays corpus unguis 33, lower sleeve 34, is used for connecting the first transition joint 35 that upper bush 31 is connected with middle sleeve, is used for connecting middle sleeve 32 and plays the second transition joint 36 of corpus unguis 33 and pass the first transition joint 35 and the second transition joint 36 and be installed on and play central axis 37 on corpus unguis 33.
In addition, the bullet pawl 331 that plays corpus unguis 33 is between hypomere axle 373 and lower sleeve 34 and be stuck in the groove 341 of lower sleeve 34 inwalls;
when the first pipe string is implanted underground work, the degree of depth that the first 14 pairs first of magnetic orientators pipe string is implanted detects, when detecting the arrival precalculated position, hanger 23 is suspended on whole the first pipe string in well, after suspension is completed, make gyroscope 16 energising detect upper in the first pipe string, the position of lower positioning key and orientation, whole releasing device 2 energisings subsequently, produce blast after blasting bolt 3711 energisings, blasting bolt ruptures from the V-type groove, well liquid enters central axis 37 piston 3721 bottoms by the central blind hole 374 in central axis 37 and flows out through the small through hole 375 that central blind hole 374 vertically connects, thereby generation pressure reduction, pushing piston 3721 makes on central axis 374 and moves, making bullet corpus unguis 33 lose to rely on retracts, the locking of releasing to lower sleeve 34, lower sleeve 34 falls, top positioner 1 can propose outside well smoothly simultaneously, thereby realize the work of giving up.
Owing to having recorded position and the orientation of upper and lower positioning key after the first lower well operations of pipe string, then implant the second pipe string and carry out underground work for the second time.
Wherein, as shown in Figure 2, the second pipe string comprises the second torpedo 38, the second cable 39, the second head harness 40, the second magnetic orientator 41, perforating gun 42, compensation pipe nipple 43, guiding device 44 and the fishing device 45 that connects successively.In the first pipe string that detects during according to the first operation, the guiding device 44 of the second pipe string is adjusted in the position of upper and lower positioning key, make lucky aligning the in orientation of the perforating gun 42 of the second pipe string treat perforation orientation, the fishing device 45 of the second pipe string directly is inserted in the fishing head 22 of the first pipe string, upper portable cable after the igniting perforation, can take out whole pipe strings, complete the oriented perforation operation.
The adverse effect of blast to gyroscope and the first magnetic orientator when further cutting down blasting bolt filled damper 46 at the front end of the blasting bolt 3711 of releasing device, and this damper 46 adopts multi-pin formula new constructions, and damping effect is better than conventional damper.
The fortuitous event that the stuck while of hanger 23 can not give up again may appear after the first pipe string is gone into the well, for being provided with safety joint 47 in the first pipe string that avoids this type of circumstances from happening, in order to can break cutting off of safety joint 47 when card well accident occurs, thereby valuable gyroscope and other strings are taken out well head, the loss when reducing something unexpected happened.
Because the utility model the first pipe string is to realize giving up by the mode that blast perforate, hydraulic drive, machinery are given up, be the accuracy rate that further guarantees to give up and locate, the utility model also the first pipe string releasing device below be provided with and shortly increase the weight of 48 and longly increase the weight of 49, making gives up makes active force larger, and effect is better.
