Abstract
The invention relates to an oil-water well unblocking drill stand, belongs to the technical field of oil production engineering application and solves the technical problem of a wellhead cap needs to be removed safely. According to the technical scheme for solving the technical problem, a main tube is connected with a cavity tube in a threaded manner, a bearing is disposed in the cavity tube, a central tube is enclosed with a spring, both a fastener bolt and an anti-rotating bolt are connected with the main tube in a threaded manner, and a drill stalk is connected with the central tube through a stem bolt. The oil-water well unblocking drill stand has the advantages that the oil-water well unblocking drill stand is applied to making an opening in a wellhead protective cap by means of cutting instead of grinding, no spark occurs, safety is good, the drill stand is light in weight and flexible and convenient to carry for construction, drilling pressure is automatically provided by the spring, and operation is simple.
Description
Technical field
The invention belongs to petroleum production engineering applied technical field, what be specifically related to is an oil-water well deblocking rig floor.
Background technology
At oil-water well, stop producing shunt in a well with wellhead cap in the situation that, when wanting deblocking, wellhead cap need to be taken down, but wellhead cap has anti-disassembling function, need to use special tool, the safe wellhead cap that take off of ability.
Summary of the invention
In order to take off safely wellhead cap, the invention provides a kind of oil-water well deblocking rig floor, can on well head protecting cover, adopt cutting but not the method opening of grinding can not produce spark, safety is good, this rig floor light and flexible, constructability carries; The pressure of the drill is given automatically by spring, simple to operate.
The present invention solves the technical scheme that its technical problem takes: a kind of oil-water well deblocking rig floor is comprised of main cylinder, spring, chamber cylinder, bearing, drillstock, central tube, drill bit, a solid seat bolt, drillstock bolt, anti-turn bolt, main cylinder and chamber cylinder are with screwed connection, bearing is contained in the cylinder of chamber, spring housing is contained in outside central tube, Gu seat bolt is all connected with main cylinder with screw thread with anti-turn bolt, drillstock is connected by turning handle bolt with central tube.
The invention has the beneficial effects as follows, this oil-water well deblocking rig floor can adopt cutting on well head protecting cover but not the method opening of grinding can not produce spark, and safety is good, this rig floor light and flexible, and constructability carries; The pressure of the drill is given automatically by spring, simple to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, by 1 main cylinder, 2 springs, 3 chamber cylinders, 4 bearings, 5 drillstocks, 6 central tubes, 7 drill bits, a 8 solid bolt, 9 drillstock bolts, 10 anti-turn bolts, formed.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated: as shown in Figure 1, a kind of oil-water well deblocking rig floor is comprised of main cylinder 1, spring 2, chamber cylinder 3, bearing 4, drillstock 5, central tube 6, drill bit 7, solid seat bolt 8, drillstock bolt 9, anti-turn bolt 10, main cylinder 1 and chamber cylinder 3 are with screwed connection, bearing 4 is contained in chamber cylinder 3, spring 2 is sleeved on outside central tube 6, Gu seat bolt 8 is all connected with main cylinder 1 with screw thread with anti-turn bolt 10, drillstock 5 is connected by turning handle bolt 9 with central tube 6.
During application, this rig floor is placed on well head, the major diameter part of main cylinder 1 bottom is entangled well head, the solid cylinder of turn bolt 8 is fixed on well head main cylinder 1 again, turn anti-turn bolt 10 is pushed down wellhead cap can not freely rotate it, shake drillstock 5, through drillstock bolt 9 and central tube 6, moment of torsion is passed on drill bit 7, to wellhead cap boring, the downforce of drill bit is given by spring 2.
