Abstract
The utility model relates to a ground compressing device required by petroleum, coal seam gas, terrestrial heat and water conservancy drilled well. The ground compressing device consists of a chain wheel group, a hydraulic cylinder, a hydraulic source and a compressing connector, wherein the hydraulic cylinder and the hydraulic source are installed on a drilling machine; the compressing connector is connected to the uppermost part of a drilling tool; a suspension end of the chain wheel group is connected with the hydraulic cylinder; a chain link sleeve of the chain wheel group is installed on a chain link tying peg of the compressing connector; and an energy storage device or a dredging pump of a blowout preventer on the drilling machine is used as the hydraulic source. The inside of the compressing connector can be rotated; the outside of the compressing connector is fixed and is not rotated. In the ground compressing device, the original equipment and tool on the drilling machine are fully utilized; the ground compressing device has simple structure, convenience for installation and reliable performance; soft compression realized by the hydraulic cylinder can ensure the stable compression and reduce bit jumping and impact on the drilling tool and a drill bit caused by the bit jumping, prolongs the service life of the drill bit and the drilling tool and improves the drilling speed; in addition, the damage to a rotary device is reduced and the safety of drilling well construction is improved because the drilling tool is compressed and the rotary device is not compressed.
Description
Technical field
The utility model relates to needed ground water booster system in a kind of oil, coal bed gas, underground heat and the water conservancy drilling well.
Technical background
In the work progress of oil, coal bed gas, underground heat and water conservancy drilling well, often run into following several situation, cause bit speed to slow down: one, surface layer is very hard, and the weight of drilling tool is too light, the tooth of drill bit can not be pressed into the stratum and effectively cut; When two, creeping into surface layer, because the admant piece is sprained and formed the jumping of spraining between gear wheel, the shortage in weight of drilling tool causes drilling tool to beat with drill bit to press steady drill bit at this moment, and rig is beated with drilling tool when serious, forms covibration; Three, on the top layer, when orientation and net horizontal section setting of casing, the phenomenon of not going under serious, the tubing string of being hampered is often arranged, if at this moment the weight of tubing string and its top equipment is less than resistance, will trip out casing string, be lowered to drill bit, well is done unimpeded, could be lowered to sleeve pipe again, so just waste a lot of times.
Summary of the invention
The ground water booster system by chain wheel set, hydraulic cylinder, hydraulic power source, add crimp head and constitute, hydraulic cylinder, hydraulic power source are installed on the rig, add the top that crimp head is connected drilling tool, the suspended end of chain wheel set is connected with hydraulic cylinder, and the chain cable of chain wheel set is enclosed within on the chain cable deadman that adds crimp head.Adopting the accumulator or the slush pump of preventer on the rig is hydraulic power source, implements pressurization continuously by carry highly pressurised liquid to tighten up chain cable to hydraulic cylinder; When not having pressure in the hydraulic cylinder and loosening chain cable, piston rod in the hydraulic cylinder and chain cable all are in free state, and drilling tool can be thus lifted to its extreme higher position, and can insert or lay down drilling tool this moment.Adding crimp head inside can rotate, and external stability is not rotated, and promptly flange joint rotates with traveling system above it and following drilling tool thereof, and transferring high voltage mud also bears the heavy duty that beam barrel applies; And axle sleeve and chain cable hitching post be fixed together and do not rotate, and flange joint is pressurizeed.
During setting of casing, according to whether wanting circulating mud, pressurized operation mode to have two kinds: one, when needing circulating mud, its mode of operation is identical when creeping into; Its two, when not needing circulating mud, two chain cables are striden across the sleeve pipe top connect tension again, can pressurize.The utility model can pressurize when creeping into, and pushes down beating of drilling tool, makes the tooth pressure of drill bit go into the stratum, improves drilling speed; Be hampered at setting of casing, can not be descending the time, this device can apply bigger pressure, forces it descending.
This device utilizes original equipment and instrument on the rig fully, simple in structure, easy for installation, dependable performance, realized in the scope of 0-200 ton, drilling tool being carried out soft (fluid power) pressurization, problems such as this has just overcome other patent family design to rig slewing (water tap, top-drive device) pressurization, and pressurization scope little (less than 10 tons), rigid (machinery) pressurization and set-up time are long.By the soft pressurization that hydraulic cylinder is realized, can make pressurization steadily, alleviate bouncing of drilling tool and bouncing of drilling tool and cause impact drilling tool and drill bit, prolong the application life of drill bit and drilling tool, improve drilling speed; In addition, to the drilling tool pressurization, and not to the slewing pressurization, the damage that has just alleviated slewing, the safety that has improved wellbore construction.
Description of drawings:
The utility model is made up of legend and case study on implementation.
Accompanying drawing 1 is a ground water booster system schematic diagram.
Accompanying drawing 2 is pressurization joint design schematic diagrames.
Legend: 1, rig overhead traveling crane, 2, derrick, 3, traveling system, 4, add crimp head, 5, chain wheel set, 6 drilling tools, 7, hydraulic power source, 8, hydraulic cylinder, 9, rig substructure, 10, the hydraulic cylinder holder, 41, the chain cable deadman, 42, axle sleeve, 43, flange joint
The specific embodiment
As shown in Figure 1 and Figure 2, the top of derrick 2 is rig overhead traveling cranes 1, its underpart is connecting traveling system 3, add crimp head 4 and be connected traveling system 3 times, its lower end links to each other with drilling tool 6, and chain wheel set 5 one ends link to each other with chain cable deadman 41, the other end is connected on the hydraulic cylinder 8, hydraulic cylinder 8 be installed in rig substructure 9 below, its bottom be hydraulic cylinder holder 10, hydraulic power source 7 is positioned at rig substructure 9.To add the top that crimp head 4 is connected drilling tool 6 during operation, the suspended end of chain wheel set 5 is connected with hydraulic cylinder 8, the chain cable of chain wheel set 5 is enclosed within on the chain cable deadman 41 that adds crimp head 4, adopt the accumulator of preventer to do hydraulic power source 7, pressurize by chain cable from chain wheel set 5 to hydraulic cylinder 8 that carry highly pressurised liquids to implement continuously to tighten up, the tonnage of pressurization is controlled (hydraulic control valve is one of parts of hydraulic cylinder) by the fluid pressures in the hydraulic cylinder 8; Loosen chain wheel set 5 when not having pressure in the hydraulic cylinder 8, the chain cable of piston rod in the hydraulic cylinder 8 and chain wheel set 5 all is in free state, and drilling tool 6 can be thus lifted to its extreme higher position, and can insert or lay down drilling tool 6 this moment.What sprocket wheel was used is jack, and the interlock of its gear and steel chain can apply very big weight, and stable.Add crimp head 4, flange joint 43 rotates with traveling system above it 3 and following drilling tool 6 thereof, transferring high voltage mud, and bear the heavy duty that axle sleeve 42 applies; And axle sleeve 42 and chain cable hitching post 41 are fixed together and do not rotate, to flange joint 43 pressurizations.Axle sleeve 42 adopts high-abrasive material, and leaves the oil filling hole.
