Description
Technical field
The present invention relates to a kind of oil reservoir logging instrument accessories, are specifically related to a kind of horizontal well female connector limit body.
Background technology
Limit body is an indispensable part on horizontal well instrument, when surveying horizontal well, when pin end and female connector pair
It is connected together, becomes the copper ring buckled and link up with the two halves copper ring just tangled on limit body, after completion is surveyed, the survey on uphole instruments vehicle
Well winch will promote instrument to well head, when promoting instrument, become the copper ring hook buckled two halves copper ring will be drawn deformation until
Copper ring hook is detached from two halves copper ring, so a two halves copper ring will be damaged by often surveying a well, two will be replaced after well logging
Half copper ring when replacing two halves copper ring, needs first to turn the locking cap being pressed on two halves copper ring, leaves two halves copper ring, ability
Two halves copper ring is disassembled, but often due to when logging well, there are oil, also mud, hydrogen sulfide gas in shaft bottom, there are these factors that can lead
Locking cap is caused to be glued on the screw thread of limit body dead, and it is stubborn motionless, it can not sometimes need to destroy locking cap, instrument is given to tie up
It repaiies and brings very big trouble, also the threaded connection place of limit body and weighted lever is also frequently necessary to dismantle, and instrument is tieed up
Maintenance is repaiied, there is also the situation that thread gluing is twisted not open, so for above-mentioned two problems, we provide a kind of horizontal well female connector and use
Limit body.
Invention content
The technical problems to be solved by the invention are to provide a kind of horizontal well female connector limit body, to the lock on limit body
Tight cap is improved, and sealing ring is also provided at the connection screw thread of limit body and weighted lever, solves limit body repair institute
The difficulty encountered.
In order to solve the above technical problems, the present invention provides following technical scheme：A kind of horizontal well female connector limit body, packet
Include weighted lever, limit body, locking cap, two halves copper ring, the weighted lever and limit body right end is threadedly coupled and threaded connection place two
Distinguish fixed first sealing ring, the second sealing ring in side；Copper ring groove, the first outer six sides are offered on the limit body, it is described
Two halves copper ring is placed in copper ring groove, and the locking cap is detachably connected by two and half locking caps and formed, the locking cap spiral shell
Line is connected on limit body, is offered silicone grease slot with locking cap threaded connection place on the limit body, is opened up on the locking cap
There is the oil filler point communicated with silicone grease slot, the oil filler point internal thread is connected with silk plug；The limit body left end is consolidated by fixed column
Surely it is connected with connector；Jump-ring slot is offered on the fixed column and limit body, there is the clamp spring that clamp spring is stuck in fixed column and limit body
In slot；Described locking cap one end is equipped with the second outer six sides, and half locking cap is equipped with threaded hole, lock is equipped in the threaded hole
Two and half locking caps are fixed together by tight screw.
The present invention has an advantageous effect in that compared with prior art：A kind of horizontal well female connector limit body, will one
Locking cap made two and half locking caps into, when two and half locking cap thread gluings are twisted to get off, two and half locking caps of directly dismantling
On lock screw, it is possible to two and half locking caps are lifted down, without using destroy by the way of, limit body and plus
Weight bar connection screw thread both ends are respectively arranged a sealing ring, during well logging, will not allow oil, mud, hydrogen sulfide gas and other impurities again
Entering in connection screw thread, when dismounting just can easily remove very much, and very big convenience is brought to apparatus guarantee work.

Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
In the description of the present invention, it is to be understood that term " longitudinal direction ", " transverse direction ", " on ", " under ", "front", "rear",
The orientation or position relationship of the instructions such as "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " is based on attached drawing institutes
The orientation or position relationship shown is for only for ease of the description present invention rather than instruction or implies that signified device or element must
There must be specific orientation, with specific azimuth configuration and operation, therefore be not considered as limiting the invention.
It is understood referring to figs. 1 to Fig. 3:A kind of horizontal well female connector limit body, including weighted lever 1, limit body 2, locking cap
3rd, two halves copper ring 4, the weighted lever 1 and 2 right end of limit body are threadedly coupled and threaded connection place both sides difference fixed first is close
Seal 203, the second sealing ring 204, the first sealing ring 203 and the second sealing ring 204 and 2 outer circle of limit body, 1 inner wall of weighted lever are close
Envelope cooperation, can protect the connection screw thread of limit body 2 and weighted lever 1 not into other materials.It is recessed that copper ring is offered on the limit body 2
Outer six sides 202 of slot 205, first, the two halves copper ring 4 are placed in copper ring groove 205, and the locking cap 3 is by two and half lockings
Cap 306 is detachably connected composition, and the locking cap 3 is threaded on limit body 2, for two halves copper ring 4 to be pressed on copper ring
In groove 205, silicone grease slot 201 is offered with 3 threaded connection place of locking cap on the limit body 2, is offered on the locking cap 3
The oil filler point 301 communicated with silicone grease slot 201.2 left end of limit body is fixedly connected with connector 5, the fixation by fixed column 6
Jump-ring slot is offered on column 6 and limit body 2, has clamp spring 7 to be stuck in the jump-ring slot of fixed column 6 and limit body 2 and realizes connection, it is this
The very convenient dismounting of fixed form.
The locking cap 3 is equipped with oil filler point 301, and silicon can be noted in the silicone grease slot 201 of limit body 2 by oil filler point 301
Fat is protected in connection screw thread not into other materials；301 internal thread of oil filler point is connected with silk plug 302, the locking cap 3 one
