Abstract
The utility model relates to a hydraulic fishable whipstock for a branch well in an oil-water well, consisting of a lower joint, a basic pipe, a slip seat, a locking block, a locking block top sleeve, a slip, a cone body, a setting pin, a ball seat pin, a steel ball, a ball seat, a central pipe, a hydraulic cylinder, a variable fastening joint, a whipstock, a release pin, a feeding rod and an upper joint; the lower joint is connected with the basic pipe by threads; the basic pipe is connected with the slip seat by the locking block; the slip is clamped in the slip seat; the cone body is sheathed on the basic pipe and fixed with the setting pin; the central pipe is connected with the basic pipe by threads; the ball seat is sheathed in the central pipe and fixed with the ball seat pin; the steel ball is placed in the ball seat and tightly supported by a spring; the hydraulic cylinder is sheathed on the central pipe and the variable fastening joint; the variable fastening joint and the central pipe, the variable fastening joint and the whipstock, and the upper joint and the feeding rod are respectively connected by threads; and the whipstock is sheathed on the feeding rod and fixed with the release pin. The whipstock solves the problem that in the prior art, the fishing out of the well can be realized by needing milling or the procedure is complex, and can be used for operation of the branch well in the oil-water well.
Description
Technical field:
The utility model relates to a kind of hydraulic pressure that Multilateral Wells is used in oil, the well can drag for whipstock.
Background technology:
Multilateral Wells has become the frontier technology of world's oil extraction with its higher oil well well yield, lower oil extraction cost, the first step of boring Multilateral Wells is exactly to leave the window that bores Multilateral Wells on former casing, this work is by whipstock and mill awl and finish jointly, existing with the whipstock of windowing mainly by hanging and split type two kinds of one seat.One seat extension whipstock need overlap to mill just can salvage well; Though and the split whipstock can be salvaged, but working procedure is complicated: be lowered to earlier base again orientation descend whipstock again, the design's hydraulic pressure can drag for the shortcoming that whipstock overcomes above-mentioned whipstock, can once go into the well and finish positioning and directing, can salvage well simultaneously after use.
The utility model content:
The purpose of this utility model provides a kind of hydraulic pressure can drag for whipstock, mills and just can salvage well or can salvage operation than complicated problems though this whipstock has solved the needs cover that exists in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of hydraulic pressure can drag for whipstock, by lower contact, parent tube, slip spider, lock dog, lock dog top cover, slips, cone, set pin, ball seat pin, steel ball, ball seat, central tube, fluid cylinder, change snapping head, whipstock, the pin of giving up, send into bar, top connection is formed; Lower contact is threaded with parent tube, parent tube is connected with lock dog with slip spider, the lock dog top is enclosed within the parent tube uses dowel fixes, slips is stuck in the slip spider seat, cone is enclosed within on the parent tube with setting dowel fixes, central tube is threaded with parent tube, ball seat is enclosed within and uses the ball seat dowel fixes in the central tube, steel ball put into use spring top clamping in the ball seat, fluid cylinder is enclosed within central tube and becomes on the snapping head, become snapping head and central tube, change snapping head and whipstock, top connection and send into bar and be and be threaded, whipstock is enclosed within to be sent on the bar with the dowel fixes of giving up.Be achieved in that lower contact can connect as required or bonding tool not, instrument be connected on to send into by top connection transfer to precalculated position in the well under the drilling tool, (because steel ball heads on spring, so can be from mud grouting.) turn on pump suppresses 7Mpa, cuts off and sets pin, hydraulic drive fluid cylinder, cone are descending, slips along cone inclined-plane layman up to the chucking casing wall.Realize the seat extension of whipstock; Continue to suppress 12Mpa, cut off the ball seat pin, at this moment descending the and pressure release of ball seat presses down again and sends into drilling tool and cut off the pin of giving up on the whipstock, and makes to send into drilling tool and whipstock breaks away from, and the seat of finishing whipstock is hung and given up.After treating that casing sidetracking is finished, special-purpose fishing tool is connected on the drilling tool lower end transfers to whipstock position in the well, utilize the sealing device shutoff whipstock centre bore on the fishing tool, suppress and cut off the pin that the lock dog top puts, lock dog top cover is descending, and lock dog skids off in slip spider, at this moment carry fishing tool on, slip spider and slips are descending along parent tube, remove slips and hang, and whipstock is salvaged well.
The beneficial effects of the utility model are that this whipstock can realize once being lowered to whipstock, and can salvage well after use; This whipstock is not limited by hole deviation; Adopt the whole seat extension of hydraulic pressure, machinery to give up, once finish positioning and directing, adopt hydraulic pressure to salvage, improved operating efficiency.
Description of drawings:
Accompanying drawing is the utility model overall structure schematic diagram.
Among the figure 1, lower contact, 2, parent tube, 3, slip spider, 4, lock dog, 5, lock dog top cover, 6, slips, 7, cone, 8, set pin, 9, the ball seat pin, 10, steel ball, 11, ball seat, 12, central tube, 13, fluid cylinder, 14, become the snapping head, 15, whipstock, 16, the pin of giving up, 17, send into bar, 18, top connection.
The specific embodiment:
In the accompanying drawings, kind divide hydraulic pressure can drag for whipstock, by lower contact 1, parent tube 2, slip spider 3, lock dog 4, lock dog top cover 5, slips 6, cone 7, set pin 8, ball seat pin 9, copper ball 10, ball seat 11, central tube 12, fluid cylinder 13, become snapping head 14, whipstock 15, the pin 16 of giving up, send into bar 17, top connection 18 is formed; Lower contact 1 is threaded with parent tube 2, parent tube 2 is connected with slip spider 3 usefulness lock dogs 4, lock dog top cover 5 is enclosed within the parent tube 2 uses dowel fixes, slips 6 is stuck in 3 of the slip spiders, cone 7 is enclosed within on the parent tube 2 fixing with setting pin 8, central tube 12 is threaded with parent tube 2, ball seat 11 is enclosed within the central tube 12 fixing with ball seat pin 9, steel ball 10 put in the ball seat 11 use spring top clamping, fluid cylinder 13 is enclosed within central tube 12 and becomes on the snapping head 14, become snapping head 14 and central tube 12, become snapping head 14 and whipstock 15, top connection 18 is and is threaded with sending into bar 17, whipstock 15 be enclosed within send on the bar 17 fixing with the pin 16 of giving up.
