Description
Technical field
The present invention relates to a kind of oil reservoir logging instrument accessory, be specifically related to a kind of horizontal well female joint limit body.
Background technology
nullLimit body is an indispensable part on horizontal well instrument，When surveying horizontal well，When male joint and female joint are docking together，The copper ring buckled links up with the two halves copper ring just tangling on limit body，After surveying completion，Logging winch on uphole instruments car will promote instrument to well head，When promoting instrument，Two halves copper ring will draw the copper ring hook buckled deformation until copper ring hook departs from two halves copper ring，So often surveying a bite well will damage a two halves copper ring，Two halves copper ring will be changed after well logging，When changing two halves copper ring，Need first the locking cap being pressed on two halves copper ring to be turned，Leave two halves copper ring，Two halves copper ring could be disassembled，But often due to during well logging，There is oil in shaft bottom、Mud，Also has hydrogen sulfide gas，There are these factors that locking cap can be caused viscous dead on the screw thread of limit body，And twist motionless，Sometimes can not need to destroy locking cap，The biggest trouble is brought to apparatus guarantee，The threaded connection place also having limit body and weighted lever also it is frequently necessary to take apart，Instrument is maintained，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 joint limit body.
Summary of the invention
The technical problem to be solved is to provide a kind of horizontal well female joint limit body, is improved the locking cap on limit body, is also provided with sealing ring at the connection screw thread of limit body and weighted lever, solves limit body and keeps in repair the difficulty run into.
For solving above-mentioned technical problem, the present invention provides techniques below scheme: a kind of horizontal well female joint limit body, fixed first sealing ring, the second sealing ring are distinguished in and threaded connection place both sides threaded including weighted lever, limit body, locking cap, two halves copper ring, described weighted lever and limit body right-hand member；Copper ring groove, the first outer six sides are offered on described limit body, described two halves copper ring is placed in copper ring groove, described locking cap is removably connected by two and half locking caps and forms, described locking cap is threaded on limit body, silicone grease groove is offered with locking cap threaded connection place on described limit body, offering the oil filler point communicated with silicone grease groove on described locking cap, described oil filler point female thread connects plug；Described limit body left end is fixedly connected with joint by fixing post.
On the basis of such scheme, described fixing post and limit body offer jump-ring slot, have jump ring to be stuck in the jump-ring slot of fixing post and limit body.
On the basis of such scheme, described locking cap one end is provided with the second outer six sides, and described half locking cap is provided with screwed hole, is provided with lock screw and is fixed together by two and half locking caps in described screwed hole.
The present invention compared with prior art has the beneficial effect that a kind of horizontal well female joint limit body, make the locking cap of one into two and half locking caps, when two and half locking cap thread gluings are twisted and are not got off, directly dismantle the lock screw on two and half locking caps, just two and half locking caps can be lifted down, it not be used in and use the mode destroyed, connect screw thread two ends at limit body and weighted lever and be respectively arranged a sealing ring, during well logging, will not allow oil again, mud, other impurity such as hydrogen sulfide gas are in entering connection screw thread, just can remove the most easily during dismounting, the biggest convenience is brought to apparatus guarantee work.

Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
In describing the invention, it will be appreciated that, term " longitudinally ", " laterally ", " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, it is for only for ease of the description present invention, rather than instruction or hint indication device or element must have specific orientation, with specific azimuth configuration and operation, be therefore not considered as limiting the invention.
Understand referring to figs. 1 through Fig. 3: a kind of horizontal well female joint limit body; including weighted lever 1, limit body 2, locking cap 3, two halves copper ring 4; described weighted lever 1 and limit body 2 right-hand member is threaded and both sides, threaded connection place respectively fixed first sealing ring the 203, second sealing ring 204; first sealing ring 203 and the second sealing ring 204 coordinate with limit body 2 cylindrical, weighted lever 1 inner wall sealing, and the connection screw thread of limit body 2 and weighted lever 1 can be protected not enter other material.Outer six sides 202 of copper ring groove 205, first are offered on described limit body 2, described two halves copper ring 4 is placed in copper ring groove 205, described locking cap 3 is removably connected by two and half locking caps 306 and forms, described locking cap 3 is threaded on limit body 2, for two halves copper ring 4 is pressed in copper ring groove 205, offer silicone grease groove 201 with locking cap 3 threaded connection place on described limit body 2, described locking cap 3 offers the oil filler point 301 communicated with silicone grease groove 201.Described limit body 2 left end is fixedly connected with joint 5 by fixing post 6, and described fixing post 6 and limit body 2 offer jump-ring slot, has jump ring 7 to realize connecting in being stuck in the jump-ring slot of fixing post 6 and limit body 2, the very convenient dismounting of this fixed form.
Described locking cap 3 is provided with oil filler point 301, can be toward note silicone grease in the silicone grease groove 201 of limit body 2 by oil filler point 301, and protection does not enter other material in connecting screw thread；Described oil filler point 301 female thread connects plug 302, described locking cap 3 one end is provided with the second outer six sides 303, second outer six sides 303 are used for tightening and unclamping locking cap 3, described half locking cap 306 is provided with screwed hole 305, is provided with lock screw 304 and is fixed together by two and half locking caps 3 in described screwed hole 305.
The principle of the present invention and advantage: before being different from, the locking cap thread gluing on former horizontal well female joint limit body takes to get off later, it is necessary to using destructive mode to take off, the most always thread gluing of the screw thread of limit body and weighted lever junction is torn open not open.The present invention changes the structure of old-fashioned limit body locking cap, locking cap is allowed to become two halves formula, when locking cap 3 thread gluing is not torn open not fall, directly the lock screw 304 on two and half locking caps 306 can be removed, just two and half locking caps 306 separately can be taken off, after cleaning, can also continue to use, save cost, a sealing ring is respectively added at the connection screw thread two ends of limit body 2 and weighted lever 1, when underground logging, oil, the material such as mud and hydrogen sulfide gas will not enter in connection screw thread again, when apparatus guarantee maintains, limit body 2 and weighted lever 1 can be dismantled the most easily, it is greatly improved the efficiency of apparatus guarantee maintenance.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
