Abstract
The invention relates to an auxiliary tool for running instruments and cables in a vertical well, and is applicable to the field of oil gas drilling and coal drilling. The auxiliary tool comprises a tool body, an annular plate, a support, a dowel, a pulley, a cross beam and force-augmenting rods. The auxiliary tool is characterized in that the tool body is a cylinder member, the lower end of the tool body is provided with a casing screw-joint pin, and the upper end of the tool body is welded with the annular plate and the force-augmenting rods. The support is welded on the annular plate, one end of the support is hinged with the cross beam, and the pulley is welded in the middle of the cross beam. The other end of the cross beam is fixed through the dowel, and the pulley is disposed on the central line of the annular plate. The casing screw-joint pin is mounted at the lower end of the auxiliary tool, and one force-augmenting rod is mounted on each side of the auxiliary tool, so that the auxiliary tool is convenient to abut with a vertical well casing and dismount from the same. The auxiliary tool is simple in structure and convenient to mount and dismount, and is a simple and reliable tool for running instruments in the vertical well, and further, can guarantee centralizer of the instruments and prevent the instruments and the vertical well casing from colliding so as to reduce damage risks of the instruments.
Description
Technical field
The present invention relates to a kind of aid that removes for instrument in peupendicular hole and cable in the downhole tool field, be applicable to oil gas, coal drilling well field.
Background technology
Along with expanding economy, the demand of the various energy and mineral products increases day by day.The exploitation of underground mine also more and more comes into one's own, and except the oil and natural gas resource of routine, the production technique of the mineral products such as coal bed gas, salt mine, natural alkali mine is development also.For example, coal-bed gas exploitation has successively passed through straight well (being peupendicular hole) pattern and horizontal well pattern and multi-branched horizontal well pattern, and the purpose of horizontal well pattern is the leakage area that increases reservoir.Because well yield is low, of poor benefits, the exploitation of coal bed gas at present is mainly to exploit by the mode of straight well and horizontal well or multi-branched horizontal well connection composition well group.In the process of two wells or the connection of many wells, subdrilling a bite straight well, and be lowered to glass reinforced plastic sleeve at target zone after the straight well finishing drilling, carry out reaming.Then carry out the construction of horizontal well, when creeping into after straight well, be lowered to the orientation construction of measuring apparatus guiding horizontal well in straight well, guarantee the smooth connection of two wells.Equally, in the exploitation of the soluble minerals such as underground salt mine, natural alkali mine and geothermal energy, the technology that straight well is communicated with horizontal well also is used widely and has been obtained good development effectiveness.
In view of the above-mentioned state of the art, need to remove measuring apparatus and cable in peupendicular hole, and the bore of down-hole casing is less, owing to lacking necessary aid, certainly will cause like this collision that removes to go out in the measuring apparatus process between instrument and sleeve pipe, cause instrument with bad, and cable also is difficult between two parties.
Summary of the invention
Purpose of the present invention is exactly the problem that exists for prior art, propose a kind of simple in structure, be convenient to installation and removal and can guarantee instrument and cable centralizer, prevent the collision of instrument and straight well sleeve pipe, the aid that removes that is used for instrument and cable in peupendicular hole of the risk that lowering apparatus damages.
Technical scheme of the present invention is: the top at tubular body upwards connects firmly annular slab, support successively, the upper level of support arranges crossbeam, the intrinsic pulley in the middle part of crossbeam, crossbeam one end and a side stand hinge, the support of the crossbeam other end and opposite side locks by pin, and wherein, the annular slab internal diameter is less than the internal diameter of tubular body, and greater than matching used instrument external diameter, pulley and crossbeam are arranged on the shaft horizontal line of body.
Described tubular body lower end is processed with screw buckle, and upper-outer circumference is fixed with boosting-rod.
Can find out from the solution of the present invention, for being lowered to and tripping out of straight well Instrumental, it is a tubular element that following advantage: A, aid body are arranged, and the lower end is processed with casing threads and connects button, the docking and dismounting of convenient and straight well sleeve pipe; B, aid dock with screw thread and straight well sleeve pipe, and safe and reliable, pulley can not produce and rock; C, pulley are positioned on the annular slab center line, can guarantee to remove the centralizer of instrument and cable by annular slab and pulley; Thereby reach the protection instrument and reduce the danger of colliding with sleeve pipe.
Description of drawings
Fig. 1 a kind ofly removes the aid structural representation for instrument in peupendicular hole and cable
In figure: 1 body, 2 annular slabs, 3 supports, 4 pins, 5 pulleys, 6 crossbeams, 7 boosting-rods.
The specific embodiment
In conjunction with Fig. 1, this invention is further elaborated.
Of the present inventionly remove aid by being formed by body 1, annular slab 2, support 3, pin 4, pulley 5, crossbeam 6 and boosting-rod 7 for the straight well cable.Body 1 is a structure tube-like piece, and the lower end is processed with casing threads and connects pin thread, upper end and annular slab 2 welding.Welding support 3 above annular slab 2, crossbeam 6 one ends and support 3 are hinged, middle welded pulley 5, the other end is fixing with pin 4.Pulley 5 is positioned on the center line of annular slab 2.This aid body 1 lower end is processed with the connection pin thread that meets the API casing threads, its specification can be for meeting following a kind of specification 4,41/2,5,51/2,6,65/8,7,75/8 of API standard, and in body 1 both sides, boosting-rod 7 is housed, the docking and dismounting of convenient and straight well sleeve pipe.
The present invention is applicable to being lowered to and tripping out of straight well Instrumental, the specific embodiment is as follows: A, instrument are lowered to, at first this aid is docked with sleeve pipe, then ready measuring apparatus is lowered in straight well by annular slab and pulley, annular slab and pulley have guaranteed the centralizer of cable; B, instrument trip out, and measuring apparatus trips out after completing underground work, trip out instrument by annular slab and pulley, dismantle this aid with boosting-rod.
This patent is simple in structure, and is easy to operate, removes in the instrument process at straight well, can well guarantee the centralizer of cable, the risk that lowering apparatus damages.
Claims (2)
1. aid that removes that is used for instrument and cable in peupendicular hole, it is characterized in that: the top at tubular body upwards connects firmly annular slab, support successively, the upper level of support arranges crossbeam, the intrinsic pulley in the middle part of crossbeam, crossbeam one end and a side stand hinge, the support of the crossbeam other end and opposite side locks by pin, wherein, the annular slab internal diameter is less than the internal diameter of tubular body, and greater than matching used instrument external diameter, pulley and crossbeam are arranged on the shaft horizontal line of body.
