Abstract
The invention belongs to a pressure drilling device of a drilling machine. The pressure drilling device is composed of a wirerope, wirerope connectors, a pressure tensioning hydraulic cylinder and idlers. One end of the wirerope is fixed on a fixed headframe through the wirerope connector, and the other end of the wirerope is connected onto the pressure tensioning hydraulic cylinder of a movable headframe. The pressure tensioning hydraulic cylinder is connected with a power head which moves on the movable headframe through a guide rail. In normal condition, the pressure tensioning hydraulic cylinder is retractable; in pressing, down force is far greater than retraction pressure of the pressure tensioning hydraulic cylinder, thus the pressure tensioning hydraulic cylinder is in the maximum position of extending stroke and drives the movable headframe to move downward, and the wirerope drives the power head to move to achieve pressure drilling. Besides, the wirerope is adjustable in tensioning degree, thereby being prevented from disorder; the head power is automatically adjusted, or lateral pressure is top driven so as to ensure the pressure to be balanced.
Description
Technical field
The present invention is applied to oil gas and unconventionaloil pool drilling envelope, is a kind of to coordinate telescopic derrick, and a kind of mechanical device of the drilling well that realizes pressurizeing in drilling process, meanwhile, this device can adjust steel wire tensioning degree, avoids occurring wire rope disorder cable phenomenon.This application of installation, in hydraulic drill rig, also can be applicable to the other types rig such as land, ocean.
Background technology
At present, domestic petroleum rig is all without pressurization drilling rig, oil-well rig mainly relies on drilling assembly deadweight realization to creep into, but at unconventionaloil pool drilling equipment and other geology, water drilling rigs etc., probing relative depth is little, drilling assembly own wt be not enough to realization creep into or drilling pressure not enough and cause bit speed slow.The invention provides a kind of pressurization drilling rig, and the transmission device tensioning degree such as wire rope in adjustable the pressure of the drill process.
Domestic rapid with the development such as coal bed gas, shale gas, become domestic frscturing main source, thus the drilling well such as coal bed gas, shale gas is strengthened.All-hydraulic drill is that a kind of range of application is comparatively wide, and advanced in performance rig, is mainly used in the drilling well such as coal bed gas, shale gas.Hydraulic drill rig configures this contrive equipment, can realize drilling well of pressurizeing.
Summary of the invention
Conventional drill relies on drilling assembly self gravitation to realize creeping into, without pressurization drilling rig.The object of the invention is to overcome unconventional rig, geological drilling rig is relative with the drilling assembly of water drilling rig etc. kicks the beam, drilling assembly own wt is not enough to realize to creep into or the not enough and defect that causes bit speed slow of drilling pressure, provides a kind of device of pressurization drilling well.
The invention provides a kind of pressurization drilling apparatus, form primarily of wire rope, wire rope connector, strain of pressure hydraulic cylinder and idle pulley.This device and rig telescopic derrick with the use of, wire rope one end is connected on fixing derrick, and the other end is connected on unit head by wire rope connector and strain of pressure hydraulic cylinder, realizes pressurization and creeps into middle pressure transmission.Portable derrick moves power resources in fluid pressure drive device or other power set.
The invention provides a kind of mounting means of drilling well of pressurizeing.Two groups of idle pulleys are arranged on fixing derrick and portable derrick, and idle pulley one is installed on portable derrick, and for transmitting power, idle pulley two is installed on fixing derrick, except transmission power, also can realize left and right pressure balance.Two groups of wire rope connectors are installed on hydraulic tensioning cylinder and unit head respectively, and for connecting steel wire ropes, strain of pressure hydraulic cylinder is installed on above the wire rope connector of fixing derrick, for transmitting power and tensioning wire rope.Wire rope, by wire rope connector, strain of pressure hydraulic cylinder and idle pulley, is connected on fixing derrick and unit head, realizes pressure transmission.
The present invention, except realizing pressurization and creeping into, can realize left and right pressure balance in pressurization drilling process.Wire rope is by idle pulley two, and adjustment left and right pressure, realizes the upper and lower pressure equalizing acted on unit head automatically.
The present invention, except realizing pressurization and creeping into, can realize steel wire tensioning, is shunk by strain of pressure hydraulic cylinder, and adjustment steel wire tensioning degree, tensioning wire rope, avoids occurring wire rope disorder cable situation.
Strain of pressure hydraulic cylinder adopts band self-locking device hydraulic cylinder, guarantees to make wire rope be in tensioning state in travel position.
Accompanying drawing explanation
Accompanying drawing is half sectional view of the present invention:
In figure 1, portable derrick 2, unit head 3, wire rope connector one
4, wire rope 5, fixing derrick 6, idle pulley one
7, wire rope connector 28, strain of pressure hydraulic cylinder 9, idle pulley two
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described: as shown in the drawing, this kind of rig pressurization drilling apparatus comprises wire rope 4, and idle pulley 1 is passed in wire rope 4 one end, connecting steel wire ropes connector 1, be fixed on fixing derrick 5, the other end is through idle pulley 29, and connecting steel wire ropes connector 27, on the hydraulic tensioning cylinder 8 on portable derrick 1, strain of pressure hydraulic cylinder 8 is connected with unit head 2, and unit head 2 can be moved by guide rail on portable derrick 1.During practical operation, hydraulic tensioning cylinder 8 is in contraction state under normal circumstances, when pressing down work, because downforce is much larger than the systolic pressure of hydraulic tensioning cylinder 8, now hydraulic tensioning cylinder 8 is in and stretches out stroke maximum position, press down power transmission to realize, portable derrick 1 moves downward, wire rope 4 one end is fixed on fixing derrick 5, stiff, unit head 2 on other end final sum portable derrick 1 connects, by wire rope 4, idle pulley 1, idle pulley 29, hydraulic tensioning cylinder 8, unit head 2 is driven to move downward, thus generation downforce, realization presses down power transmission, reach the object of pressurization drilling well.
Wire rope 4 tensioning realizes, input certain pressure hydraulic oil, and driving pressure hydraulic tensioning cylinder 8 shrinks, and adjustment wire rope 4 tensioning degree, tensioning wire rope 4, avoids wire rope 4 to occur disorder cable situation.
