CN203547533U - Anchoring and orientation integration whipstock base tool - Google Patents

Abstract

The utility model relates to the technical field of oil field drilling completion, in particular to an anchoring and orientation integration whipstock base tool. A lower joint, a center tube and an orientation sleeve are sequentially connected from bottom to top; a slip bowl is sleeved outside the center tube; a slip is mounted onto the slip bowl; a cone is arranged on the upper portion of the slip and is fixed onto the center tube through a cone pin; an anti-inverting ring sleeve is sleeved outside the upper end of the cone; an anti-inverting ring is mounted on the anti-inverting ring sleeve; the anti-inverting ring sleeve, a force transmission casing and an expandable bell mouth are sequentially connected from bottom to top; the inner wall of the lower joint is connected with a clamp spring; the inside of the clamp spring is connected with a ball seat cover, the inside of the ball seat cover is connected with a ball seat; the ball seat cover, an inlet pipe I, an inlet pipe II, an inlet pipe III and a hydraulic cylinder are sequentially connected from bottom to top. According to the anchoring and orientation integration whipstock base tool, the base anchoring closing and the orientation sleeve direction measurement can be achieved through one-step drilling, so that the drilling cost is saved and the operational risk is reduced. The shortcoming of two-step drilling for the base anchoring closing and the orientation sleeve direction measurement as well as time-consuming and effort-consuming deficiencies are overcome.

Description

A kind of grappling and directed integrated whipstock base means

Technical field:

The utility model relates to a kind of oil field drilling completion technique field, particularly a kind of grappling and directed integrated whipstock base means.

Background technology:

The on-the-spot method that the definite location of windowing of straight well section (5 ° of hole deviation <) is used is comparatively loaded down with trivial details at present, for example, is first lowered to grappling whipstock base to precalculated position, and realization sets; Be lowered to again gyro to measure instrument to lower bevel position measurement base orientation, according to design bearing meter, calculate whipstock orientation.These action needs are lowered to twice and bore, and not only expend man-hour, and increase construction risk.

Utility model content:

The technical problems to be solved in the utility model is to provide a kind of grappling and directed integrated whipstock base means, and this device has been realized base grappling is set with surveying orienting cover orientation and bored for one time, saves drilling cost, reduces operating risk.Having overcome existing base grappling sets and surveys orienting cover orientation and need to be lowered to twice and to bore, the deficiency taking time and effort.

Technical solution adopted in the utility model is: a kind of grappling and directed integrated whipstock base means, comprise lower contact, central tube, power transmission shell and inflatable horn mouth, lower contact, central tube, orienting cover connects from bottom to up in turn, on central tube, be set with slip spider, slips is installed on slip spider, cone is placed in slips upper end and is fixed on central tube by cone pin, inverted-proof ring is placed on cone upper end, inverted-proof ring puts installation inverted-proof ring, anti-down ring set, power transmission shell, inflatable horn mouth connects from bottom to up in turn, lower contact inwall connection circlip, jump ring inner side connects ball seat cover, ball seat cover inner side connects ball seat, ball seat cover, send into pipe I, send into pipe II, send into pipe III, fluid cylinder connects from bottom to up in turn, send into pipe II outside and be set with sleeve, send between pipe II and sleeve retainer spring is installed, on sleeve, be designed with positioning key, positioning key extend in the fluting of power transmission shell under the effect of retainer spring, piston is arranged in fluid cylinder.

The beneficial effects of the utility model are: the utility model is owing to having adopted the mode of Design Orientation key, thereby have base grappling is set and the function of surveying orienting cover orientation and having bored for a time, save drilling cost, reduce operating risk.

Accompanying drawing explanation:

Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.

Fig. 1 is structural representation of the present utility model.

The specific embodiment:

As shown in Figure 1, a kind of grappling and directed integrated whipstock base means, comprise lower contact 1, central tube 5, power transmission shell 13 and inflatable horn mouth 20, lower contact 1, central tube 5, orienting cover 14 connects from bottom to up in turn, on central tube 5, be set with slip spider 6, slips 7 is installed on slip spider 6, cone 9 is placed in slips 7 upper ends and is fixed on central tube 5 by cone pin 10, anti-down ring set 11 is placed in cone 9 upper ends, on anti-down ring set 11, inverted-proof ring 12 is installed, anti-down ring set 11, power transmission shell 13, inflatable horn mouth 20 connects from bottom to up in turn, lower contact 1 inwall connection circlip 2, jump ring 2 inner sides connect ball seat cover 3, ball seat overlaps 3 inner sides and connects ball seat 4, ball seat cover 3, send into pipe I 8, send into pipe II 15, send into pipe III 19, fluid cylinder 22 connects from bottom to up in turn, send into pipe II 15 outsides and be set with sleeve 16, send between pipe II 15 and sleeve 16 retainer spring 18 is installed, on sleeve 16, be designed with positioning key 17, positioning key 17 extend in the fluting of power transmission shell 13 under the effect of retainer spring 18, piston 21 is arranged in fluid cylinder 22.

Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; As long as meet, use needs, all within protection domain of the present utility model.
