Description

A kind of measurable well head connection sealer of pressure
Technical field
The utility model relates to a kind of measurable well heads of pressure to connect sealer.
Background technique
Traditional wellhead sealing device has no the validity that simple effective means seals wellhead sealing device after mounting Real-time live verifying is carried out, is leaked in production process, can only stop producing, carry out kill-job and plays well operations, replaces shaft bottom Wellhead sealing device can generate the operating cost of great number in this way, waste the production time and have security risk.
Summary of the invention
It is measurable convenient for the pressure that monitors, be easy to use that in view of the above problems, the object of the present invention is to provide a kind of Well head connects sealer.
The technical scheme for implementing the utility model is as follows
A kind of measurable well head connection sealer of pressure, including transfer tube, connecting tube and upper connecting tube, the transfer tube One end and connecting tube one end be tightly connected, the other end of connecting tube and upper connecting tube are formed and are tightly connected, when transfer tube, connection After pipe, upper connecting tube connection, the cable passage that current supply cable passes through is formed inside three, is set respectively in the transfer tube, connecting tube It is equipped with the cutting ferrule for being formed to cable and clamping clamping, test chamber is formed between two cutting ferrules, offers and survey in the radial direction of transfer tube The instrument connection that chamber forms connection is tried, the plug for forming sealing to instrument connection is equipped in instrument connection.
Further, the cutting ferrule is stainless steel cutting ferrule.
Further, the instrument connection is bellmouth, and bellmouth is gradually reduced inwardly on the outside of connecting tube.
Further, the test hole wall is 1/16NPT taper thread.
Further, the plug is the taper thread plug of 1/16NPT.
Further, the other end of the transfer tube is equipped with connector, and the outer peripheral surface of connector is gradually to subtract outward Small taper connection face.
Using above-mentioned technical proposal, connects sealer and installed with wellhead tee joint, cable is drawn and carries out wiring; Before connection sealer comes into operation or in use process, when normal operating condition, plug is assemblied in instrument connection to survey It tries chamber and forms closure sealing, when being tested, plug is backed out, using pressure device, through instrument connection into test chamber Injection pressure, it can wellhead sealing device is carried out to suppress test, thus can be to the effective of wellhead sealing before production Property determined, wellhead sealing device resistance to compression state is intact before guaranteeing production, to reduce security risk, and reduces rising for great number Well operations expense.
Detailed description of the invention
Fig. 1 is the use state diagram of the utility model;
Fig. 2 is the pressure device schematic diagram for suppress to the utility model test.
In attached drawing, 1 is transfer tube, and 2 be connecting tube, and 3 be upper connecting tube, and 4 be sealing ring, and 5 be cable, and 6 be cutting ferrule one, and 7 are Cutting ferrule two, 8 be test chamber, and 9 be instrument connection, and 10 be connector, and 11 be taper connection face, and 12 be seal head, and 13 be sealing ring, 14 It is wellhead tee joint for isolation cabin, 15.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer The technical solution of the utility model embodiment is clearly and completely described in the attached drawing of type embodiment.Obviously, described Embodiment is a part of the embodiment of the utility model, instead of all the embodiments.Based on described the utility model Embodiment, those of ordinary skill in the art's every other embodiment obtained under the premise of being not necessarily to creative work, all belongs to In the range of the utility model protection.
As shown in Figure 1, a kind of measurable well head of pressure connects sealer, including transfer tube 1, connecting tube 2 and upper connecting tube 3, transfer tube, connecting tube, upper connecting tube are hollow, both ends open tube body;One end of transfer tube and the sealing of connecting tube one end connect It connecing, the other end and upper connecting tube of connecting tube, which are formed, to be tightly connected, and sealed connection is used between tube body end and is threadedly coupled here, And sealing ring 4 is cooperated to form sealing.
After transfer tube, connecting tube, upper connecting tube connection, the cable passage that current supply cable 5 passes through, switching are formed inside three Pipe is respectively arranged with cutting ferrule 1, the cutting ferrule 27 for being formed to cable and clamping clamping in connecting tube, in the pipe between two cutting ferrules Test chamber 8 is formed, is offered in the radial direction of connecting tube and forms the instrument connection 9 that is connected to test chamber, is equipped in instrument connection pair Instrument connection forms the plug of sealing, and when needing to test, plug being disassembled, when without testing, plug being packed into instrument connection, with Test chamber is blocked.In specific implementation, the first cutting ferrule, the second cutting ferrule are stainless steel cutting ferrule, and cutting ferrule can be using a few days ago normal Ferrule structure realizes, not described here any more.
Instrument connection is bellmouth, and bellmouth is gradually reduced inwardly on the outside of connecting tube, in order to guarantee plug and instrument connection Between sealing performance, test hole wall be 1/16NPT taper thread, plug be 1/16NPT taper thread plug.
The other end of transfer tube is threaded with connector 10, and one end of connector is threadedly coupled and is configured with transfer tube Sealing ring is sealed, and the outer peripheral surface of the connector other end is the taper connection face 11 being gradually reduced outward, taper connection face On screw thread is distributed with, the end and wellhead tee joint 15, which are formed, to be connected, to guarantee connection sealing.
For the sealer using 1/8 " stainless steel cable as shaft bottom cable, cable uses routine 8mm cable;In transfer tube and Two-stage sealing is realized to cable connection using two group of 1/8 " metal ferrule between connecting tube, and forms hermetical testing chamber;Upper The end of adapter tube is connected with seal head 12, sealing ring 13, between connecting tube and upper connecting tube connect after inside formed it is closed every From storehouse 14;Packing seal is used between seal head, sealing ring, upper connecting tube, isolation cabin and wellhead cable 5, thus to wellhead cable Realize seal protection in part.Seal head 12, upper connecting tube 3, isolation cabin 14, connecting tube 2, transfer tube 1, is tightly connected at sealing ring 13 First 10 are sequentially connected.
The shaft bottom Fig. 2 well head connects sealer sealing validity test signal.When needing to test, the stifled of instrument connection is backed out Head can carry out wellhead sealing device suppressing test by the instrument connection using manual pressure test pump, suppress corresponding to bottom pressure Value, if pressure gauge indicating value 4 hours remain unchanged, then it is assumed that wellhead sealing device sealing is effective.
