Description
Technical field
The utility model relates to a kind of Portable hand wellhead cable protective device, belongs to oil and gas exploration Horizontal Well Drilling platform shaft drilling tool transmission well logging construction operation field.
Background technology
At present, in horizontal well or High angle well logging, generally adopt drilling tool to be sent into by instrument and go into the well, dock logging cable by wet-make connection, drilling tool followed by cable and instrument is transported to down-hole, just can complete horizontal wellbore logging task.Wire outer wrapping insulation materials, is as easy as rolling off a logly damaged.To in delivered downhole cable construction process, logging cable protection must be carried out at drilling floor surface.As cable directly contacts with horn mouth at well head, cable wearing and tearing are severe.In addition, when transferring drilling tool, the elevator hanging drilling tool is easy to cable of damaging, and causes cable to disconnect or cable core insulation reduction, success log ratio is reduced; Easily cause the generation of engineering accident.
Publication number is 2592859, and publication date is that the Chinese patent literature on December 17th, 2003 discloses a kind of oil well cable spool self-locking protector, is specially adapted to the fixing of the cable conduit at oil well oil conduit box cupling place and protection.This utility model is blocked surely, dynamic card by pinned connection, and can rotate around bearing pin, and fixed card studs with rubber sheath; dynamic card was locked by self-locking chain pin with fixed the card, during use, opened dynamic card; cable, spool are loaded in protective sleeve; close dynamic card, with long arm clamp by chain pin with determine kayser tightly, during dismounting; insert in the flat side of chain pin with open-end wrench; rotate clockwise 90 °, can automatically throw off, easy accessibility.
But with the prior art that above-mentioned patent document is representative, though it has certain cable protection function, its complex structure, is not easy to carry, the requirement of drilling tool transmission well logging construction operation under well head rotating disk condition can not be met.
Summary of the invention
The utility model is intended to for the defect existing for above-mentioned prior art and deficiency; a kind of Portable hand wellhead cable protective device is provided; the utility model structure is simple, is easy to carry, and under can not meeting well head rotating disk condition, drilling tool transmits the requirement of well logging construction operation.
The utility model realizes by adopting following technical proposals:
A kind of Portable hand wellhead cable protective device, it is characterized in that: comprise cable protecting part and fixed part, described cable protecting part comprises two clamping plates, axle and pulley, described pulley is arranged between two clamping plates by axle, described pulley and axle are at least two groups, two groups of intervals and be inclined between two clamping plates, part between two clamping plates above two groups of pulleys forms cable protection groove, described fixed part comprises fixed cylinder, fixed cylinder is fixed between two clamping plates, fixed cylinder is for fixing with locating hole on offshore boring island well head rotating disk rolling square column.
On described two clamping plates, activity chain is connected to carrying handle.
Described cable protecting part is arranged on cylindrical shell, is fixed together with cylindrical shell.
Described pulley and axle are four groups, four groups of intervals and being inclined between two clamping plates.
Described fixed part also includes stationary steel bushing, and fixed cylinder is placed in described stationary steel bushing.
Compared with prior art, the beneficial effect that reaches of the utility model is as follows:
One, the utility model adopts the form of structure of cable protecting part and fixed part, can meet all Oil/gas Wells under offshore boring island 375 model quadrel condition, transmit well logging construction operation condition, can meet again the function of protection cable.This device fixed cylinder can be arranged to two kinds of forms; the rolling square column locating hole that can meet two kinds of different models is installed; cable protection groove, axle and pulley is provided with above clamping plate; identical active force can be afforded to solve each pulley; according to the angle that cable runs up and down on the position arranging pulley, distributed four groups of cable protection wheel distributions in domatic.Portable hand tree-protector, do not need special train roping, light and handy ease of assembly again gets up very quick, and serve special process transmission borehole log wellhead cable protection effect on offshore boring island, meet the function of cable protection, prevent the construction works accident caused because cable fault causes cable breakage, i.e. handled easily but also install very easily, solve the angle of cable under drilling floor surface well head to rig floor between horn mouth distance simultaneously, solve in the past because of injury that the large cable of angle collides and weares and teares on horn mouth, protect cable to greatest extent, reduce construction operation risk, improve transmission well logging timeliness, reduce operating cost.
Two, in the utility model, the pulley coordinated with cable in described clamping plate, is provided with.Further ensure and protect cable, reduce construction operation risk, improve transmission well logging timeliness.
Three, in the utility model, described cylindrical shell is provided with and cylindrical shell all-in-one-piece two clamping plate, between two clamping plate, forms cable protection groove.Not only be convenient to the connection with pulley, and be convenient to arrange installation pulley.
Four, in the utility model, described pulley and axle are four groups, and in cable protection groove, the distribution in domatic, adopts the guiding of this structure to cable more accurate.
Five, the utility model proves through the offshore boring island drilling tool transmission well logging construction operation that too much well is secondary, and its security performance and practicality can meet the needs of offshore boring island 375 model well head rotating disk construction operation completely, reach all technical and the requirement of design.
Six, in the utility model, the fixed cylinder be connected can divide two kinds of modes to fix according to the rotating disk diameter that locating hole is fixing on square column that rolls.
Seven, in the utility model, on described two clamping plates, activity chain is connected to carrying handle, is easy to carry.
