Description
Technical field
The present invention relates to workover rig device technique field, be a kind of separate type workover rig and using method thereof.
Background technology
At present in the workover treatment of oil test operation, company needs substantial amounts of expense to be used for fixing derrick to stand up and transport every year, costly, if all adopting current well maintenance vehicle as lifting means from now on, feature according to oil test operation, the vehicular well maintenance vehicle having 4/5 is left unused, and needs the maintenance cost costed a lot of money.
In the prior art, the derrick of sectional needs fragmented transport to well site, need to transport with on crane lifting to flat car, behind well site, first segmentation crane is unloaded down, carry out being assembled into one after derrick, integral vertical gets up again, then need to realize erecting or putting down of derrick with two large-scale cranes, causes cost of transportation high.
The derrick of sectional is in transport and stands up and belongs to high-risk operations content category in process, need equipment and the personnel of auxiliary many, particularly there is well site staff in the process of standing up and hang, with high-altitude, the unsafe factor that thing intersects, cause installation cost high, dangerous big.
Current workover rig is when carrying out promoting operation, common practice is to be fixed on derrick leg by dead line anchor, adopting mechanical tensile forces meter to read hook load, but could realize the broken steel wire rope section of turning round of steel wire rope damage if this mode exists installation period length, need to extract whole steel wire rope out when steel wire twists, whole spooling such as scraps at the defect.
Summary of the invention
The invention provides a kind of separate type workover rig and using method thereof, overcome the deficiency of above-mentioned prior art, it can effectively solve current workover rig derrick transport and installation needs fragmented transport, installs to cause and transport the problem that installation cost is high, installation risk is big, maintenance cost is high, and the current workover rig of solution cannot realize steel wire rope and break the problem that torsion causes steel wire rope waste serious when carrying out promoting operation further.
One of technical scheme is realized by following measures: a kind of separate type workover rig, including upper joint derrick, lower joint derrick, derrick base, extending cylinder, on-vehicle host, derrick bracket；Upper joint derrick is sleeved in lower joint derrick, upper joint derrick and lower joint derrick are installed with guy wire respectively, upper joint derrick is provided with floating device, the lower end of lower joint derrick is hinged on derrick base, the body of lower joint derrick and extending cylinder is fixedly installed togather, and the piston rod of upper joint derrick and extending cylinder is fixedly installed togather；Derrick bracket includes support body, bracket raising cylinder, the front arm distinguishing L-shaped curved shape and rear arm；Together with the bottom of support body links with the right-hand member of on-vehicle host, bracket raising cylinder is fixedly mounted in on-vehicle host, the piston rod of bracket raising cylinder and support body are fixedly installed togather, hydraulic control power set it are installed with on the left of the upper end of support body, on the left of the support body of corresponding hydraulic control power set, front end is installed with front mounting seat, on the left of the support body of corresponding hydraulic control power set, rear end is installed with rear mounting seat, front mounting seat and rear mounting seat are respectively articulated with relatively rotate and can hold lower joint derrick tightly, rotate in opposite directions and can unclamp the front arm of lower joint derrick and rear arm, the power output shaft of hydraulic control power set is hinged with the left end of front arm and rear arm respectively.
Further optimization and/or improvements to foregoing invention technical scheme one of are presented herein below:
Above-mentioned separate type workover rig also includes dead line anchor and steel wire rope, dead line anchor is fixedly mounted on derrick base, on-vehicle host is provided with working rig winch and single-chip microcomputer, the one ends wound of steel wire rope is on working rig winch, it is fixed on dead line anchor after the other end pile warp floating device of steel wire rope, having sensor on dead line anchor, the signal output part of sensor and the signal input part of single-chip microcomputer are electrically connected by wire.
The sensor is pulling force sensor.
Above-mentioned floating device includes overhead traveling crane and hook, overhead traveling crane is fixedly mounted on the upper end of joint derrick, being installed with dead line sheave on overhead traveling crane, the one ends wound of steel wire rope, on working rig winch, is fixed on dead line anchor after the other end pile warp dead line sheave of steel wire rope and hook.
Above-mentioned hydraulic control power set hold tightly before including hydraulic cylinder and after hold hydraulic cylinder tightly, front and rear on the left of the upper end of support body hold tightly before being installed with respectively hydraulic cylinder and after hold hydraulic cylinder tightly, hold front end on the left of the support body of hydraulic cylinder before correspondence tightly and be installed with front mounting seat, hold rear end on the left of the support body of hydraulic cylinder after correspondence tightly and be installed with rear mounting seat, front hold tightly hydraulic cylinder and after to hold the piston rod of hydraulic cylinder tightly hinged with the left end of front arm and rear arm respectively.
The two of technical scheme are realized by following measures: the using method of a kind of separate type workover rig, when needs carry out hauling operation, control hydraulic control power set and make front arm and rear arm hold lower joint derrick tightly；When needs carry out standing up operation, the piston rod first controlling bracket raising cylinder stretches out, and then risen by the piston rod supporting frame of bracket raising cylinder, when support body acts the angle rising to needs, stop hoisting support body, then passing through control hydraulic control power set makes front arm and rear arm part unclamp lower joint derrick, continue the support body that hoists, derrick base is made to be snapped down to ground, until lower joint derrick is in operating angle, after the guy wire of lower joint derrick is drawn, the piston rod controlling extending cylinder stretches out, after upper joint derrick is risen to working depth, most post-tensioning is the upper guy wire saving derrick well；When needs carry out promoting operation, first making working rig winch rotate, the load of floating device is delivered on dead line anchor by boom hoist cable, all the time pinch sensors, the pressure signal that sensor produces, by wire and on-vehicle host socket connection, realizes load on single-chip microcomputer and shows；When needs carry out folding and unfolding operation, first receive the guy wire of upper joint derrick, then the piston rod controlled on extending cylinder is regained, upper joint derrick is fallen after rise to lower joint derrick, then receives the guy wire falling down joint derrick, control hydraulic control power set and make front arm and rear arm hold lower joint derrick tightly, lower joint derrick and support body is made to be close to, then receiving the guy wire falling down joint derrick, the piston rod finally controlling bracket raising cylinder is regained, and makes support body and lower joint derrick and upper joint derrick slowly drop back into on-vehicle host.
