Description
Technical field
The present invention relates to a kind of winch rolling screw rope guide and rope-discharging method thereof.
Background technology
Although of all kinds on various winch structure, generally all consist of the following components in essence:
(1) cylinder, drum shaft assembly, this is the core work parts of winch.Cylinder should have enough Rong Shengliang, guarantees that rope woolding is in good condition to extend rope service-life;
(2) winch has sensitive failure-free main brake mechanism and well behaved assist brake, can regulate exactly the pressure of the drill, evenly sends drilling tool to, arbitrarily controls running speed and effortlessly the heaviest drill string load is checked in going down process;
(3) cat head and cat shaft assembly are in order to satisfy the needs with shackle on tong and other auxiliary lifting.Bailing drum also is housed, in order to extract core barrel on some cat shafts;
(4) transmission gear shift system introduces and distributed power and transmit motion, and enough shelves speed is provided;
(5) control system comprises dental inlay, tooth-like, pneumatic clutch.Their general subordinates are in the component part of control system of rig;
(6) lubricating system comprises that butter is lubricated, drip feed lubrication and sealing, splashes or positive lubrication;
(7) support system has frame bracket or the closed box shell-type mounting of welding.Medium-sized winch integral transportation, its weight is in 10 tons; Heavy and superduty winch will be broken into shipped, and the unit of transportation should be in 15 tons, so that movement.
In the middle of Process of Oil Well Drilling, the radical function of winch shows:
(1) drilling tool (comprise grief joint, drilling rod, brill very, drill bit etc.) is lowered to hundreds of rice to several kms, even surpasses the shaft bottom of myriametre.
(2) with drilling tool from hundreds of rice to several kms, the shaft bottom of even going up myriametre trips out.
(3) in drilling well, foil portion drilling tool weight, be pressed in pressure on drill bit with control.
(4) in drilling well, as down-hole accident occurs, need to be lowered to or to trip out the various downhole tools of processing the down-hole fault in pit shaft.
(5) install at rig, when dismantling, need derrick integral body is stood up or transferred.
(6) in cement job, need to be lowered to sleeve pipe etc. in well.
According to function and the characteristics of winch, in general, the well borer does that winch is had following requirement:
(1) in order to guarantee the heaviest drilling tool that hoists, require each parts of winch to satisfy in intensity, rigidity under the prerequisite of its in-use performance, winch will have enough power.
(2) variation and the raising effect in order to adapt to hoisting capacity, winch should have enough hoist gear number or speed change scope of compromise.
(3) winch drum should have enough sizes and Rong Shengliang.
(4) winch should have sensitive failure-free brake system, in order to check maximum load, accurately regulates the pressure of the drill, evenly sends drilling tool to.
(5) the winch control part is answered convenient operation, and is safe and reliable.
The transmission scheme of winch has determined its structure type, can be divided into single shaft, twin shaft, three axles, multiaxis and major-minor winch by the winch number of axle.The first two is planted winch and generally all needs change speed gear box in addition
1. single drum shaft winch
The characteristics of this class winch are that cat head directly is contained in drum shaft two ends, and cylinder is contained on drum shaft.For different lifting velocities is provided, change speed gear box transmission winch and rotating disk respectively are set outside winch.This winch structure is simple, and power is little, and is lightweight, and movement is convenient, is exactly this type as C-1500 type boring winch.Its shortcoming is that the cat head rotating speed is higher, and the position is too low, operation inconvenience, and cylinder shelves speed can not independently arrange, the impact speed that makes a trip.
2. twin-roll axle winch
Double shaft drawworks is comprised of cat shaft and drum shaft, due to cat head and cylinder split axle, the speed of cat head and position is all improved, and has solved the operation inconvenience problem of cat head.It still takes outer speed change scheme.Adopt this scheme as ZJ15D and ZJ20-2 ton type rig, lightweight so that winch structure is simple, be convenient to movement.
3. three drum shaft winches
The characteristics of this class winch are to have increased the transmission shaft of introducing power on the basis of double shaft drawworks, and cat shaft is also participated in gear.The JC1-14.5 winch that grand celebration 130 rigs and ZJ130-1 adopt namely belongs to this type of, and it can realize separate three low gears and a high speed gear.Because space between three axles is larger, reverse gear can not be set, this type rig is provided with reverse gift gearing box at machine room.Because speed-changing mechanism is also taken into account rotating disk, cancelled outer change speed gear box, but winch itself is complicated.Weigh 20 tons, be converted into four shipped of three axles during movement, movement and installation are all inconvenient.
4. multiple-roll axle winch
Winch more than four axles is called multiaxial drawworks, is characterized in that cat shaft do not participate in gear, the position that is available in the middle of cat head can install auxiliary bailing drum additional, and separately establishes the requirement that tween drive shaft solves speed change and transmission.Generally can realize 6 positive 2 drum speeds that fall, the domestic drillings such as ZJ32J, ZJ45, ZJ45J, ZJ60D all adopt this scheme.
5. major-minor winch
Multiaxial drawworks has solved many-sided contradictions such as variable speed operation, shipment preferably on organization plan.But the climbing of long winch, chain has become the weakest link in the rig transmission.Modern deep-well, superdeep well drill floor get up higher (9m as high in the ZJ60L rig floor), the winch of 20 tons of left and right of weighing on the one hand hangs to rise and becomes difficulty, long-chain is climbed up rig floor and will do not increased not 1～2 tween drive shaft and center base on the other hand, makes its transmission complicated, and efficient is low.So independent cat shaft-main winch organization plan occurred.
The main winch power demand is large, is contained on the machine room base, and cat shaft and rotary table transmission device consist of separate unit and be placed on rig floor.Greatly improved the service conditions of climbing chain (or versatile spindle) because Rotary Table Power is less, facilitated and install and movement.
Make a general survey of the developing history of rig, rig has experienced one from simple to complex, and low to the high development and change process of automatization level by automatization level, the evolution of drilling well whim is like this too.Along with making rapid progress of the up-to-date technologys such as Eltec, hydraulic technique, petroleum drilling winch will develop towards the following aspects.
(1) further to electric driving direction development.Reason is that direct current SCR controls and AC frequency conversion is controlled rig and winch, and the incomparable preceence of other many drill outfits is arranged.Except a handful of countries such as the U.S., other country is still relatively backward aspect the development electric drilling machine at present, is still the megatrend of following rig research and development, general orientation.
(2) further to automation, intelligent direction effort.For safety, efficient, scientific and rational drilling well, developed hydraulic drive rig, full automatic drilling rig etc. abroad, this can produce great impact to China's Future Development automation, product that intelligent level is higher.
(3) continue to the maximization future development.Present has been developed the drill outfit of upper myriametre, ConUS one Ai Musike company developed 5000 horsepowers of winches of the first in the world platform in 1997, be described as the 5th generation electric lifting device, so, for further improving domestic drilling tech, the trend of development high-power winch is inevitable.
(4) to split type, single axle future development.At present, main winch and the catworks of many rigs have adopted Split type structure, are placed in respectively on drill floor face and background base, by independently actuating unit driving.The single axle winch is popular in the west in recent years, and the common feature of these two kinds of winches is simple in structure, and volume is little, and is lightweight, is convenient to transportation installation etc.
(5) to seriation, normalisation, the effort of modularization direction.Along with the further normalization of world market, drill outfit is inevitable to the trend of the future developments such as seriation, normalisation, universalization, and this is conducive to increase the interchangeability of equipment and the stability of properties of product, and can save a large amount of productive costss.
(6) to the high-adaptability future development.Restriction owing to being subjected to the drilling conditions such as desert, ocean, polar region wants to expand the oil production market segment, and the drill outfit that adapts to these harsies environment and weather just must be arranged, therefore, the drill outfit of exploitation high-adaptability be from now on the inevitable requirement in future.
When the fast line of petroleum drilling machine winch is wrapped in end on cylinder, there is angle between fast line and plumb bob vertical, the fast line leaning angle must be controlled in certain scope, if leaning angle is excessive, the drift angle that steel rope is entangled to cylinder will increase, thereby cause strengthening along the cylinder axial force between fast line and adjacent fake, must impact the normal winding of steel rope at cylinder.In addition, along with the increase of leaning angle, the race of steel rope and crown sheave just might wear and tear, and along with the increase of leaning angle, it is serious all the more that wearing and tearing can become, and causes great impact this service life on steel rope.
Boring winch is one of core component of oil-well rig.Used well drilling hoist system does not generally have rope guide, cause many rig cylinder steel ropes the sequence disorder to occur, cause disorder cable, steel cable to push mutually, make steel rope produce gross distortion, distortion, bending, knotting, have to scrap in advance, not only cause significant wastage, more seriously may bury thus serious potential safety hazard, especially in the use of deep-well, superdeep well winch, this phenomenon is very general especially.At present, although have the guiding steamboat on winch, this guiding steamboat also just plays the effect that prevents that steel rope from swinging, and is difficult to tackle the problem at its root.
