The multifunctional fast-assembled type cable blowout control box has the advantages that the cable blowout control box utilizes three stages of sealing bodies, each stage of the sealing body is independent, all internal accessories can be penetrated with the cable when mounting without making a headstall again, the cable blowout control box is adaptable to cables with different types, and corresponding internal accessories can be replaced fast according to the types of the cables.
Description
Technical field
The utility model relates to the oil reservoir logging technical field, the cable blowout hookup that particularly a kind of sleeve in oil field well surveying is on probation.
Background technology
At present, domestic used cable blowout prevention box is fixed blowout prevention box, and the cable of different model such as ￠ 5.6mm, ￠ 8mm, ￠ 11.8mm etc. have corresponding with it fixed blowout prevention box.But carrying out disparity items when well logging, just need choose the cable blowout prevention box that is complementary with cable size according to the model of cable, take to cut to fall head harness, the cable blowout prevention box that will not match disassembles, with the cable blowout prevention that matches box-packed on, make head harness again.Its shortcoming is:
(1) it is long to produce time, needs the fixed cable blowout prevention box of replacing and makees head harness again;
(2) often dismantle head harness, the shell of wearing and tearing head harness has shortened its application life;
(3) consume the needed accessory of head harness, cause the cost waste;
(4) fixed cable blowout prevention box body is long-pending huge, is not easy to deposit, transports and assembles;
(5) fixed cable blowout prevention box accessory is changed difficulty, can only cut off cable when accessory damages and change;
(6) fixed cable blowout prevention box overall weight is big, needs crane to cooperate when installation and removal.
The utility model content
The purpose of this utility model is: a kind of multi-functional fast assembling cable blowout prevention box is provided, can only need changes corresponding interior fittings according to the cable model, do not need the head harness of reforming when changing accessory; And volume is little, and is in light weight, easy installation and removal.The production time that overcomes the replacing fixed cable blowout prevention box that fixed cable blowout prevention box exists and do again that head harness causes is long; Often dismantle the shell of wearing and tearing head harness, reduction of service life; Again do the head harness consumption part, cause the cost waste; Bulky, be not easy to deposit, transport and assemble; Accessory is changed difficulty, can only cut off cable when accessory damages and change; Overall weight is big, needs deficiencies such as crane cooperation when installation and removal.
The technical solution adopted in the utility model is: multi-functional fast assembling cable blowout prevention box, mainly form by sealing shroud, sealing shroud lining body, pressure-bearing pad, sealing mat, grease pouring valve, relief valve, shell and following end joint, shell is a rounded cylindrical, it is characterized in that: be fixed with end joint down at the little lower end of shell screw thread.Following end joint can dock with well head, and three groups of seals that are made of pressure-bearing pad and sealing mat are arranged in the enclosure.Pressure-bearing pad and sealing are lined with centre bore, can pass cable.Between per two groups of seals, 10～50 mm distance are arranged, form hydrops chamber and resin flux chamber.The hydrops chamber is used to collect the fluid on the banded cable, and the resin flux chamber is in order to store lubricating grease.Sealing shroud lining body is arranged on the seal top of upper end, in the middle of the sealing shroud lining body sealing shroud is arranged.Sealing is with centre bore, can pass cable.
Described seal is made up of two pressure-bearing pads and a sealing mat, and pressure-bearing pad and sealing mat are cylindric, and sealing mat is between two pressure-bearing pads.
In order to release by the liquid that hydrops is indoor, on the wall of shell, be fixed with a relief valve, relief valve and hydrops chamber UNICOM.
In order on the wall of shell, to be fixed with a grease pouring valve to the indoor injection lubricating grease of resin flux.Grease pouring valve and resin flux chamber UNICOM.
In order to assemble fast, described shell is formed by connecting by three threaded cylinders in two ends and two joints.
The beneficial effects of the utility model: the multi-functional fast assembling cable of the utility model blowout prevention box has following advantage: multi-functional fast assembling cable blowout prevention box adopts three grades of seals, each grade seal all is independently, all inner accessories can both make cable pass through during installation, do not need to do again head harness; Be suitable for the cable of different model, can select for use corresponding interior fittings to change fast according to the cable model; During site operation, can carry out multistage quick assembling as required.Grease pouring valve and hand greasing pump connect, and satisfy the on-site cable lubrication needs; Volume is little, in light weight simultaneously, does not need the cooperation of working rig and crane during construction.
