Abstract
A mechanical and hydraulic double action releasing tool is used for the completion drilling operation of the oil and gas field. A body cavity of an external cylinder assembly is provided with an annular flute, which is matched with a claw sleeve of a feeding tool. A lower sliding sleeve is in sliding clearance fit with a lower contact. A hydraulic chamber is formed by a lower sliding sleeve cavity step and the lower contact. A plurality of radial through holes is arranged on a center rod, in communication with the hydraulic chamber. An upper sliding sleeve and middle sliding sleeve are secured together by a shear pin. The external surface of the upper sliding sleeve is equipped with a step, which is matched with the cavity step of the claw sleeve. The middle sliding sleeve is fastened on the center rod by the shear pin. An anti-rotation mechanism is positioned between the external cylinder assembly and the feeding tool assembly. The releasing operation in mechanical or hydraulic mode can be realized by the utility model through the structural improvement of the tool, so as to solve the problem that the releasing cannot be carried out in regular reverse mode due to the disallowance of the rotation of the completion pipe string and the other special reasons, and the opposite rotation of the blocking piece and the body can be prevented by the special matching structure.
Description
Technical field
The utility model relates to the releasing tool of oilfield drilling, completion practice, particularly a kind of machinery and hydraulic double-acting releasing tool.
Background technology
At present, one of key technology in solid both at home and abroad, the completion practice in sidetracked hole, horizontal well, Multilateral Wells etc. be exactly the tail pipe string can be smoothly, accurately give up.Existing releasing tool mainly is divided into mechanical type and fluid pressure type dual mode, for the mechanical type releasing tool, owing to adopt the mode of giving up of back-off, thereby can't realize the rotation of completion tubular column, when in case tubing string is hampered, can only by on put and put tubing string and solve blocked portion, but poor effect often.For the fluid pressure type releasing tool, too much because of its Hydraulic Elements, after tubing string is gone into well, through regular meeting for various reasons, when down to predetermined well section, but can't realize effectively giving up.
Summary of the invention
The purpose of this utility model is to provide a kind of completion tubular column rotation of can realizing, and can adopt machinery and hydraulic pressure dual mode give up effectively assurance the give up machinery and the hydraulic double-acting releasing tool of job success.
The utility model mainly is made up of outer barrel assembly and running tool assembly, outer barrel assembly is made up of tieback tube 1 and body 2, tieback tube 1 adopts with body 2 and is threaded, running tool assembly and outer barrel assembly link together, running tool center-pole 9 two ends are threaded with top connection 3, lower contact 18 respectively, wherein:
Body 2 inner chambers designs has an annular groove with certain width;
It is polygonal annular for being reserved with a cross section that the pawl of running tool overlaps 13 bottoms, on the leap loop configuration, be reserved with circumferentially uniform saturating groove of some, and its polygonal cross-section matches with the outer step of lower contact 18 and the body 2 interior steps of outer barrel assembly respectively;
Some circumferentially uniform axial step shape steps are arranged at top connection 3 bottoms, and the stepped groove that matches with top connection 3 axial step shape steps is arranged at urceolus 4 tops;
Center-pole 9 inner surfaces, upper sliding sleeve 10 external surfaces have all designed pawl, and all cooperate with two-way pawl ring 12 formation;
Design has rotation-preventing mechanism between outer barrel assembly and the running tool assembly.
The utility model can make corresponding shear pin cut off respectively by building the pressure or pressing down the tubing string mode, deviates from from outer barrel assembly thereby drive the pawl cover, realizes giving up.The utility model is by the improvement on the tool construction, having realized can be by the operation of giving up of machinery or hydraulic pressure dual mode, solved because of the completion tubular string and the problem that cause specific can not adopt conventional back-off mode to give up such as do not allowed to rotate, simultaneously by adopting the special fit structure of fixture block and body, prevent relatively rotating between the two.

The specific embodiment
The utility model is described in more detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model mainly is made up of outer barrel assembly and running tool assembly, outer barrel assembly is made up of tieback tube 1 and body 2, tieback tube 1 adopts with body 2 and is threaded, running tool assembly and outer barrel assembly link together, running tool center-pole 9 two ends are threaded with top connection 3, lower contact 18 respectively, wherein:
Body 2 inner chambers designs has an annular groove with certain width;
It is polygonal annular for being reserved with a cross section that the pawl of running tool overlaps 13 bottoms, on the leap loop configuration, be reserved with circumferentially uniform saturating groove of some, and its polygonal cross-section matches with the outer step of lower contact 18 and the body 2 interior steps of outer barrel assembly respectively;
Some circumferentially uniform axial step shape steps are arranged at top connection 3 bottoms, and the stepped groove that matches with top connection 3 axial step shape steps is arranged at urceolus 4 tops;
Center-pole 9 inner surfaces, upper sliding sleeve 10 external surfaces have all designed pawl, and all cooperate with two-way pawl ring 12 formation;
Design has rotation-preventing mechanism between outer barrel assembly and the running tool assembly.
As further improvement of the utility model, can adopt following anti-rotation structure: some is arranged along circumferentially uniform axially saturating groove in body 2 tip designs, there is the circumferential uniform groove of some at urceolus 4 middle parts, compression spring 5, snap ring 6, upper sliding sleeve 10, middle sliding sleeve 15 are sleeved on the center-pole 9 successively with low sleeve 17, compression spring 5 is between top connection 3 and snap ring 5, snap ring 6 links into an integrated entity by bolt 8 with fixture block 7, and fixture block 7 cooperates with circumferentially saturating groove formation on the urceolus 2.
In addition, when preventing to adopt mechanical system to slip out of the hand, the pawl cover is deviate from from upper sliding sleeve, can also take following structure: have annular groove at the upper sliding sleeve external surface, back-up ring 11 is installed in the groove.
The utility model operating principle is as follows: be lowered in the process at tubing string, outer barrel assembly is connected with bottom tail pipe string, utilizing the groove of body 2 inside of outer barrel assembly to form with running tool median claw cover 13 between outer barrel assembly and the running tool cooperates, thereby realize suspension to the tail pipe string, and can utilize the lower contact 18 of running tool to connect suitable interior pipe string according to actual conditions.Be lowered to when being hampered at tubing string, can utilize fixture block 7 on the running tool to drive outer barrel assemblies and together rotate, thereby guarantee being lowered to smoothly of tubing string.When completion tubular string during down to the precalculated position, build the pressure by in managing, can cut off the middle sliding sleeve 15 of running tool and the shear pin 14 between the center-pole 9, under the effect of hydraulic pressure, pawl cover 13 is together up with upper sliding sleeve 10, middle sliding sleeve 15, low sleeve 17, the elastic claw that pawl overlaps 13 bottoms will break away from the groove of outer barrel assembly inside and enter the inside of urceolus 4, thereby realize giving up of tail pipe string.After hydraulic pressure is given up inefficacy, can directly press down tubing string, cut off the shear pin between upper sliding sleeve 10 and the middle sliding sleeve 15, pawl cover 13 is together up with upper sliding sleeve 10, and the elastic claw that pawl overlaps 13 bottoms can enter the inside of urceolus 2, thereby realizes giving up of tail pipe string.
