Description
Technical field
The present invention relates to the manufacturing technology field of underground operation tool, specifically relates to a kind of liner-type well completion and enters well work
Tool, for realizing long horizontal sections bushing pipe bottom cycle.
Background technology
As the continuous development of drilling technology, high-inclination horizontal well are more and more.In recent years, high-inclination horizontal well is mainly used
Crack is crossed in exploitation low permeability fractured stratum, because High angle horizontal segment can tiltedly wear, flat payzone of wearing is longer, is considerably increased
The bare area of oil gas, so as to greatly improve oil and gas production.But high-inclination horizontal well is to deep-well Holes of Complicated Wells well-completing process
Propose severe challenge.Liner-type well completion technology is due to low etc. all with reservoir protec-tion, formation damage, cost simple to operate
More advantages, horizontal well selective completion is more and more using liner-type well completion technology both at home and abroad at present, and liner-type well completion turns into level
One of important completion mode of well.Do not carry out systematic research also for deep-well, Holes of Complicated Wells liner-type well completion technology both at home and abroad at present,
Deep-well, Holes of Complicated Wells, high angle hole liner-type well completion technology not yet obtain important breakthrough.
Publication No. CN2310148, publication date disclose a kind of level for the Chinese patent literature on March 10th, 1999
Well Multifunction complete well tube, be mainly made up of hydraulic releasing tool, completion tubular column and washover pipe, wherein completion tubular column mainly by
Sleeve pipe, hanging packer, centralizer, slotted liner, sealing shroud and guide shoe etc. form；Washover pipe is mainly by flush pipe and sealing
Intubation composition.The tripping in construction of this Multifunction complete well tube, can be to well while slotted liner completion is realized
It is rinsed and acidizing treatment, reduces oil layer pollution, improves oil well productivity, hydraulic releasing tool is given up reliably, easy for construction.
But the prior art using above-mentioned patent document as representative, however it remains following technical barrier：Ensure in High angle water
Sent under horizontal well section bushing pipe smoothly in place, the card that is hampered can establish circulation scouring pipe shoe and annular space, and dredge reduce annular space resistance turn into
Important problem urgently to be resolved hurrily.
The content of the invention
It is contemplated that the defects of present in above-mentioned prior art and deficiency, there is provided a kind of horizontal well liner-type well completion enters
Well instrument, the present invention can realize bushing pipe bottom cycle, once it is hampered or bit freezing can use bushing pipe bottom cycle, the bubble measure solution such as acid
Card.
The present invention is realized by using following technical proposals：
A kind of horizontal well liner-type well completion enters well instrument, it is characterised in that including releasing tool, insertion instrument and the instrument of inserting is waited,
The releasing tool is connected to insertion instrument upper end by drilling rod, and insertion instrument is combined on the instrument of inserting is waited by sealing structure
End, with when plug in instrument and be attached with releasing tool by bushing pipe and bunch tube.
Described releasing tool is provided with dual bearing structure, and upper bearing (metal) is arranged on lifting short circuit lower end, and lower bearing is arranged on
Insertion instrument upper end.
Described releasing tool mainly by lifting short circuit, sand cap, tie-back sleeve, give up left-hand thread pin end and give up left-hand thread mother
Joint is formed, and is provided with upper bearing (metal) in lifting short circuit lower end, and upper bearing (metal) lower end is provided with upper bearing (metal) underlay, lifting short circuit top with
Drill rod thread connects, and lifting short circuit and sand cap mode connects for screw, lift short circuit lower internal thread and left-hand thread pin end of giving up is trapezoidal
Threaded connection, left-hand thread female joint upper external thread of giving up are threadedly coupled with tie-back sleeve, give up left-hand thread female joint internal thread and function
The left-handed trapezoidal thread connection of thread bush, left-hand thread pin end of giving up are connected with function thread bush keyway, left-hand thread pin end bottom of giving up
It is threadedly coupled with turning to male, turns to male with turning to female and be provided with sealing structure, left-hand thread pin end bottom of giving up is with turning to
Female is provided with lower bearing between top, and left-hand thread female joint bottom of giving up is threadedly coupled by variable buckle pin end with bottom bushing pipe,
Female bottom is turned to be connected with bottom drill rod thread by variable buckle pin end.
Insertion instrument adjusts deep intubation and target seeker to form by sealing, and sealing adjusts deep intubation top to connect with variable buckle public access head thread
Connect, bottom is threadedly coupled with target seeker.
Wait the instrument of inserting to be made up of pin and box sub, insertion seat and insertion seat interior sealing, pin and box sub top connects with bushing pipe screw thread
Connect, sealing structure is provided between pin and box sub and insertion seat, insert inside seat and adjust deep insert by inserting seat interior sealing and sealing
The seal of tube combines.
Compared with prior art, what the present invention was reached has the beneficial effect that：
1st, bushing pipe bottom cycle can be realized.The tool tubular column is waited in socket using interior insertion drilling rod insertion, when turn on pump circulates
Drilling fluid is returned out by interior insertion drilling rod through guide shoe, realizes the circulation of drilling fluid of full well section, while without slip design, in lower brill
When being hampered can turn on pump circulation, not by circulation pump pressure limited.
2nd, can realize without in point of neutralization back-off.Due to not sitting extension, certain suspending weight being hung with inside and outside releasing tool and outer outstanding
It is more difficult that weight is less big, design size space is small, horizontal segment fixed point is given up, therefore the instrument does not use hydraulic releasing mode, and
The ripe back-off of selection is given up technology, and back-off part of giving up has used thrust bearing, will be fed into drilling tool decentralization and is carried in back-off portion
Point high friction rotational resistance load transfer be low friction rotational resistance load, be sent into drilling tool and liner portion give up back-off when can
Need not strictly find the point of neutralization, improve back-off reliability, the thick left-hand thread of fixation is changed be set to can axial movable thick left-hand thread,
It is sent into drilling tool and liner portion and gives up and the back-off without axial load can be achieved during the entire process of back-off rotate, avoids appearance of giving up
It is abnormal.
Interior insertion drilling rod does not rotate when the 3rd, being sent into the rotation of drilling tool back-off.Increase between releasing tool and interior insertion drilling rod
If cylindrical roller thrust bearing, during back-off rotates, rotation torque is not transferred on the interior insertion drilling rod of lower section,
It ensure that interior insertion drilling rod will not rotate, interior insertion drilling rod can rise with the trip-out for being sent into drilling tool.
4th, completed in small design size space.
5th, can tieback.
