Abstract
The utility model discloses a running casing tool of a hydraulic driving machine. The tool is composed of an upper coupling and a casing pipe spinner joint matched with the upper coupling. The upper end of the upper coupling is provided with a threaded joint connected with a top drive main shaft, two symmetric guide grooves are formed in the middle of the upper coupling, plug pins are arranged at the corresponding positions of the guide grooves, the casing pipe spinner joint is provided with two symmetric positioning pins, the positioning pins can be clamped in the guide grooves and slide along the guide grooves, and the plug pins are used for locking the positioning pins. The running casing tool has the advantages of being compact in structure and easy to operate, simplifying well opening operation, reducing labor intensity of workers, improving work efficiency and reducing comprehensive cost of well drilling.
Description
Technical field
The utility model belongs to oil drilling and extracting equipment technical field, casing appliances used while being specifically related to a kind of hydraulic drill rig setting of casing.
Background technology
Casing job is one of significant process of drilling well, conventional technical method is: rig is equipped with tourist bus, hook, the first-class lifting means of the fire hose, and the main hook of hook hangs water tap, and the auxiliary hook of hook both sides hangs the upper end of double-arm lifting-ring simultaneously, suspension ring lower end is connected with elevator, and elevator holds sleeve pipe.When setting of casing, lifting means move up and down the docking that realizes sleeve pipe, sleeve power tongs and casing slip be used in conjunction with the torque value that sleeve pipe is tightened to regulation.
The method needs the cooperation of manpower, and labour intensity, operating efficiency, field work safe degree also need further improvement.In view of the limitation of conventional casing job, China has now developed top-drive device, drive on top has torque and the advantage such as speed control is accurate, no matter in drilling process, still make a trip in process, can rotary drill column limit, limit circulating fluid, greatly reduce the complex situations such as be hampered, stuck.Top is driven casing pipe running device and is intended replacing the equipment such as the widely used casing tong of current drilling well.
Summary of the invention
The above-mentioned defect existing for solving prior art, the purpose of this utility model is to provide a kind of hydraulic drill rig casing appliances, has compact conformation, simple to operate, simplify well head operation, reduce labor strength, and then raising operating efficiency, reduce drilling well integrated cost.
The technical scheme adopting is: this hydraulic drill rig casing appliances, it is characterized in that: the sleeve pipe spinner joint coordinating by upper box cupling with upper box cupling forms, described upper box cupling upper end has with top drives the nipple that main shaft is connected, the mid portion of upper box cupling has two symmetrical guide grooves, and guide groove correspondence position is provided with latch; Described sleeve pipe spinner joint is provided with two symmetrical alignment pins, and alignment pin can snap in guide groove and slide along guide groove, and latch is used for locked to upper box cupling and sleeve pipe spinner joint location.
Described guide groove is back-shaped guide groove.
Adopt the beneficial effect of technique scheme: this hydraulic drill rig casing appliances and top are driven and be used in conjunction with, this instrument is cylindric, upper end is nipple, on middle sleeve pipe, on the face of cylinder of box cupling, there are two symmetrical guide grooves, bottom is sleeve pipe spinner joint, have an alignment pin above, alignment pin can slide along guide groove, and available latch is locked.When work, upper end nipple and the top of this instrument are driven main shaft and are connected, the torque wrench moment of sleeve pipe can drive accurate control casing job by top time.The sleeve pipe spinner joint of instrument lower end is connected with sleeve pipe, after sleeve pipe spinner joint is connected with sleeve pipe, top is driven box cupling on the sleeve pipe that this instrument of power drive is provided and is rotated a certain angle, alignment pin on joint is entered in guide groove, and after along guide groove to its operating position, promote latch by locked to upper box cupling and sleeve pipe spinner joint location.That finally drives by top moves up and down, rotatablely moves, complete handling casing string and on pull work.
This tool construction is simple, compact, and casing job no longer needs the rig tools such as suspension ring, elevator, sleeve power tongs, gives full play to the superiority that drive on top, simplifies well head operation, reduces labor strength, and then improves operating efficiency, reduces drilling well integrated cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is box cupling structural representation on sleeve pipe.
Fig. 3 is sleeve pipe spinner joint design schematic diagram.
The specific embodiment
Hydraulic drill rig casing appliances as shown in Figure 1, 2, 3, the sleeve pipe spinner joint 4 coordinating by upper box cupling 2 with upper box cupling forms, described upper box cupling upper end has with top drives the nipple 1 that main shaft is connected, two symmetrical guide grooves 6 of mid portion of upper box cupling, described guide groove is back-shaped guide groove, and guide groove correspondence position is provided with latch 3; Described sleeve pipe spinner joint is provided with two symmetrical alignment pins 5, and alignment pin can slide along guide groove by guide groove guide groove, and latch 3 is for locked alignment pin 5, thereby by locked to upper box cupling and sleeve pipe spinner joint location.
After this instrument and top are driven main shaft and be connected, top is driven and is driven this instrument to be displaced downwardly to the correct position on drill floor face, opens locking latch, and the sleeve pipe spinner joint of bottom is shifted out along guide groove.2, sleeve pipe is placed on discharge frame, moves on to tram by special purpose device, and the center line that now sleeve pipe drives main shaft with top roughly overlaps.3, after sleeve pipe is connected with the sleeve pipe spinner joint in step 1, top is driven box cupling on the sleeve pipe that this instrument of power drive is provided and is rotated a certain angle, alignment pin on guide groove on box cupling and sleeve pipe spinner joint on sleeve pipe is aligned, alignment pin behind operating position, promotes locking latch alignment pin is locked along guide groove.4, top is driven to provide on power and is carried sleeve pipe, and the lower end of sleeve pipe is docked with the sleeve pipe on drill floor face, and top is driven and rotated, and provides moment of torsion sleeve pipe to be tightened to the torque value of regulation.5, sleeve pipe moves down, until tram.6, repeat above step, lower complete all sleeve pipes.
Claims (2)
1. a hydraulic drill rig casing appliances, it is characterized in that: the sleeve pipe spinner joint coordinating by upper box cupling with upper box cupling forms, described upper box cupling upper end has with top drives the nipple that main shaft is connected, the mid portion of upper box cupling has two symmetrical guide grooves, and guide groove correspondence position is provided with latch; Described sleeve pipe spinner joint is provided with two symmetrical alignment pins, and alignment pin can snap in guide groove and slide along guide groove, and latch is used for locked to upper box cupling and sleeve pipe spinner joint location.
