Description
Technical field
The present invention relates to oil-gas field development field, particularly a kind of Microdrilling horizontal well coiled tubing drilling robot
Supporting construction.
Background technology
At present, go deep into exploration and development, deep-well/ultra-deep horizontal well and Microdrilling（Less than 88.9mm）Horizontal well
Deng be drilled that drill string horizontal segment extension difficulty during well is big, proposed for this and utilize well borer people solution drill string horizontal segment
Extension problems.Downhole drill robot is to develop to come on the basis of downhole tractor, but than downhole tractor structure more
Complexity, particularly well borer people are provided with slurry channel, and under the conditions of reaching identical tractive force, well borer people compares downhole tractor
Size is bigger.
The mode of traction of robot is divided into roller creeping-type and crawler belt creeping-type by its supporting way and motion principle（Chain rail
Formula）Wall telescopic slide formula is leaned on grabbing（Step-by-step movement）, wherein wheeled appearance is more early, telescopic to take second place, crawler type is the latest.Three compares
Under telescopic robot tractive force it is larger, structure is compacter, is suitable for less well.Downhole drill robot is in small well
When working in the eyes, larger tractive force is not only provided, the pressure of the drill to be also provided for drillng operation, therefore is selected telescopic as micro-
The mode of traction of slimhole drilling robot is a kind of reliable selection.And the supporting construction of robot is that robot can be fitted
Answer Microdrilling operation and the primary study content of enough tractive force and the pressure of the drill is provided.
The downhole tractor development abroad time is longer, and technology is more ripe.So far, mainstream product has GE companies
The wheeled tractors of sondex, the wheeled tractors of PowerTrac of Asker Solution companies, the Well of Welltec companies
The wheeled tractors of Tractor, the wheeled tractors of Tufftrac of Schlumberger companies, the PowerTrac of MSW companies
INVADER crawler type tractors, the telescopic tractors of Oil Tubing Tractors of WWT companies, Smart Completion
The telescopic tractors of Smar Tract of company, the telescopic tractors of Catapult of Omega companies.Wherein wheeled and crawler type
The robot Outside Dimensions of supporting way are larger, and tractive force is smaller, the conduct in Microdrilling operation of the small-sized robot in part
Tractor is fine, but for Microdrilling well borer people just dying.Wherein supporting way is the support of telescopic tractor
Structure is not mostly compact and high to material requirements, causes tractor to involve great expense, and tractive force is small, and supporting construction is big, adapts to well
The defects of eye is larger, it is impossible to adapt to Microdrilling drillng operation.
But no matter which kind of tractor, external that strict secrecy provision is all taken to the country, domestic development obtains also late, native land
The interior research to downhole tractor is still in the starting stage.Occur at home first till now from tractor technology in 2002, state
Interior a small number of scientific research institutions are studied tractor, have also applied for some patents.For the supporting construction of tractor, these
Tractor more or less has some shortcomings.Disclosed in Chinese patent 200520008070.8 under a kind of Horizontal Well it is wheeled from
Pipe crawling device is adapted to, a kind of sleeve pipe horizontal wellbore logging tractor reducing traction is disclosed in Chinese patent 200720190260.5
Device, both tractors use wheeled supporting construction, and structure is not compact, and outside dimension is big, may be only available for large hole,
Microdrilling operation is not applied for, it is limited in one's ability to adapt to caliber.Daqing Petroleum Institute Shao keeps monarch, and the one kind that Chang Yulian proposes rises lock
The telescopic drag device of formula walking（Shao keeps the oil well fault-finding robot research grand celebration study of petroleum of the monarch based on virtual prototype
Institute Master's thesis .2007:5-7）, this tractor supporting construction uses linkage so that structure is not compact, tractor external diameter
It is larger, it is limited to adapt to borehole diameter.
The experimental study stage is in both at home and abroad for Oil/gas Well downhole drill robot, yet there are no the report of widespread adoption
Road, downhole drill robot are divided into two kinds of ratel well borer people and telescopic well borer people.Wherein ratel well borer people
For drilling well drilling, only need robot body to complete whole drilling operation tasks, be permanently present after reaching specified location
In underground, monitored in real time for subsequent job, can be only applied to Exploration Domain can not carry out operation to development well；It is wherein flexible
The more ripe company of formula well borer people's technology only has WWT companies, the B2 of Patent No. US 7954562 of the WWT applications U.S.
A kind of entitled Expandable Ramp Gripper well borer people's supporting construction of patent disclosure, the supporting construction use
Member structure overhangs spring leaf support, and structure is not compact, can not be applied to Microdrilling well borer people, the application of WWT companies
A kind of B2 of Patent No. US 7191829 U.S. Patent Publication entitled Gripper Assembly For of the said firm
Downhole Tools supporting construction, the supporting construction promote the roller being installed on spring leaf to release bullet using wedge slope
Reed, the supporting construction enlarging rate is small, and spring leaf is very thin so that supporting mechanism support force deficiency, the patent No. of WWT companies application
For a kind of B2 of US 8061447 entitled Varible Linkage Assisted Gripper support of U.S. Patent Publication
Structure, the supporting construction equally overhang spring leaf using bar linkage structure so that and supporting construction enlarging rate is limited, support force deficiency,
Microdrilling well borer people can not be applied to.It is continuous that China Patent No. " 201210290226.0 " discloses a kind of motor driving
Oil pipe downhole tractor, the tractor is provided with mud runner, and available for well borer people, but the tractor uses multiple motors
Screw-drive mechanism is driven to release supporting mechanism, multiple motors are circumferentially arranged, can not be minimized, it is impossible to be used in Microdrilling bores
Well robot.
Sum it up, it is no matter domestic or external, draw robot or the supporting construction energy of well borer people without a kind of
It is enough to meet the conditions such as structure is small, tractive force is big, enlarging rate is big simultaneously.
The content of the invention
The shortcomings that it is an object of the invention to overcome prior art, there is provided one kind is compact-sized, enlarging rate is big, is applicable well
The support knot of Microdrilling horizontal well coiled tubing drilling robot small, support force is big, wearability is good, offer frictional force is big
