I-Dog leg reamer ingaxhunywa ngentambo yokubhoboza futhi izuze ukuvuselelwa okuncane lapho kubholwa.

Ithuluzi linamasethi amabili ama- blade okuvunguza angaphezulu naphansi. Iqembu le-blade engezansi linomthwalo wemfanelo wokubuyisela kabusha ngenkathi kubhoboza noma ukubhola phambili phakathi nenqubo yokumba, futhi iqembu le-blade ephezulu libhekene nokubuyisela emuva emuva ngesikhathi senqubo yokukhubeka. Umsebenzi oyinhloko waleli thuluzi ukunciphisa ubunzima benkinga ye-doglegs emithonjeni eqondisayo, ukususa ama-micro-doglegs kanye nezinyathelo ezincane emthonjeni, ekuvuvukeni kokwakheka kwe-shale kanye nemibhede ye-gypsum enosawoti enwabuzelayo, amadwala agelezayo, imibhede yamalahle nezinye izigaba zomthombo. i-borehole enobubanzi obungaphezudlwana kobubanzi bethiyori be-drill bit inganciphisa isikhathi sokumba ngesikhathi sokumba okuvamile, futhi iqinisekise ukusebenza okuphephile nokushelelayo njengokukhubeka, ukuhlola ugesi, ukugijima kwekesi, kanye nokufakwa kwamapaki wokunweba. Ngaphezu kwalokho, leli thuluzi libuye libe nomsebenzi wokuhlanza umbhede wokusika emithonjeni eqondisayo kanye nokulawula ngempumelelo i-ECD yemithombo evundlile kanye nemithombo yokufinyelela enwetshiwe.
Izici:
1. Ingxenye eyodwa, azikho izingxenye ezihambayo, amandla aphezulu kunamandla wepayipi yokubhoboza exhunywe kuyo;
2. Ixhunywe kuntambo yepayipi yokubhoboza, kuma-derricks amaningi, akuthinti ukubekwa kwezintambo kanye nokusebenza kwedekhi yesibili;
3. Isenzo esiphindwe kabili se-hydraulic kanye nemishini sibhubhisa futhi sisuse umbhede wokusika;
4. Isici esiwumgogodla esikabili singanweba usayizi wembobo ube mkhulu kunobubanzi bethuluzi;
5. I-spiral blade isiza ukuthuthukisa ukuzinza kwentambo yokubhoboza ngesikhathi sokusebenza;
6. Izakhiwo zokusika ezingaphezulu neziphansi zingafinyelela ukuphinda kuvuselelwe noma ukubuyisela emuva;
7. Ingasetshenziselwa ukusebenza kwembobo ngaphambi kokuhlolwa kukagesi, ukugijima kwe-casing, ukunwetshwa kwepaki egijima, njll.;
8. Nciphisa noma uqedele inkinga ye-dogleg encane;
9. Nciphisa isikhathi sokuvuselela kanye nezikhathi zokudlula.

Ithuluzi le-Dog Leg (DL) Reamer, elidizayinelwe ukuqina okukhulu, linomumo we-eccentric olivumela ukuthi libhoboze izimbobo ezinkulu kunalokho elidlula kuzo. Ithuluzi likhulisa umthombo, likongela uhambo olufushane oludla isikhathi.

I-API Drilling Chinese Downhole Drilling Mud Motor iwuhlobo lwethuluzi lokumba imigodi elinikezwa udaka. Udaka olusuka empompini yodaka lungena emoteni ngendlela ye-bypass valve, bese ukwehla kwengcindezi phakathi kwe-motor inlet ne-outlet kudalwe, ukwehla kwengcindezi okunjalo kuzoshayela i-motor rotator ukuthi ijikelezise, ​​futhi idlulisele i-torque nesivinini sokujikeleza ukuze kancane nge-universal shaft kanye ne-transmission shaft. . Impahla ye-downhole motor incike kakhulu kumapharamitha wesakhiwo sayo. Lo mkhiqizo usebenzisa ubuchwepheshe obuphezulu nobusha bokuhlanganisa ukuze ugweme ukumbozwa ngama-rotor okubangelwa ubuchwepheshe bendabuko. Amandla ayo kanye nempilo kuthuthukiswa kakhulu. Isebenza Ekubhobolweni Okuqondile Okuqondile, ukumba okuyinhlanganisela, imithombo yeqoqo, imithombo echezukile kanye nokusebenza kahle kwequla, Ukusebenza Kwepayipi Elihlanganisiwe, njll.doi-whole drilling motor

I-Downhole motor iwuhlobo lwe-positive- displacement downhole motor(PDM).Ngemuva kokuthi uketshezi olumba ngomfutho ophezulu lungene kumotho we-downhole usuka esiqwini sokubhoboza, ingcindezi yoketshezi iphoqa i-rotor ukuthi ijikelezise okudlulisa i-torque iye kubhithi ukuze kufezwe injongo yokumba.

Ama-downhole motor ahlukahlukene kasayizi wequla 1 7/8"~26"  ngokucaciswa kobukhulu obuyinhloko obungu-24 (okubonwa ngobubanzi be-stator)  : 1-11/16", 2-1/8", 2-3/8 ", 2-7/8", 3-1/8", 3-1/2", 3-3/4", 4", 4-1/8", 4-3/4", 5", 5-1/4", 5-7/8", 6-1/4", 6-1/2", 6-3/4", 7-1/4", 7-3/4", 8 ", 8-1/4", 8-1/2", 9", 9-5/8", 11-1/4".

Ifomu lesakhiwokuhlanganisaokuqondile, ukugoba okukodwa, ukugoba okukabili, i-engeli okulungisekayo nokunye. Ibanga lokushisa elimelana nokushisa lihlanganisa  250°F (120℃) noma ngaphansi kuka-250℉ (120℃), naphakathi kuka-250 ℉(120℃) kuya ku-355℉ (180℃). Futhi singahlinzeka ngazo zonke izicaciso kuhlanganiseinjini evikela udaka esekelwe kuwoyela kanye nenjini ekwazi ukumelana nodaka emanzini anosawoti agcwele.

Izici Ezivelele

Izinga lokujikeleza elihlukahlukene kanye ne-torque, ukusebenza kahle okuphezulu, ibanga lokugeleza elibanzi, ukusebenza okushelelayo, ukunakekela okulula, ukwethembeka okuphezulu, impilo ende yesevisi.

Uhlelo lokusebenza oluphephile

Amandla anele kanye namadivayisi aklanywe ngokukhethekile amaningi angawa ukuze kuqinisekiswe ukusebenza kokumba okuphephile.

Injini evamile ye-downhole iqukethe izingxenye ezilandelayo:

(1) Ukuhlanganisa i-float noma ukuhlanganiswa kwevalvu ye-By-pass

(2) Ukuhlanganiswa kwe-rotor anti-drop

(3) Ukuhlanganisa isigaba samandla

(4) Ukuhlanganiswa kwe-shaft yendawo yonke

(5) Ukuhlanganiswa kwempahla

Ngokungeziwe kunjini evamile ye-downhole, izingxenye ezilandelayo zezinjongo ezikhethekile ziyatholakala ukwenza injini ye-downhole ekwazi ukuqondisa ukuze ihlangabezane nezimfuneko ezihlukahlukene zokusebenza kokumba:

(1) Ijoyinti yokuqondisa

(2) Ijoyinti le-Gobela (elifakwe ngenhla noma ngezansi kwendlela yokudlula

i-valve yokwenza i-motor eyodwa noma kabili egoba phansi)

(3) Isigaba samandla edlula angenalutho

(4) I-Fixed Bend Housing (ene-engeli egxilile engu-0~3°)

(5) Izindlu ezigobayo ezilungisekayo

(6) Isinzinzisi sezindlu ekuhlanganisweni kwebhodi

(7) Isinzinzisi esingashintsha

(Amanye Amamodeli akhona ukuze uthole ireferensi yakho, amamodeli engeziwe kanye nama-deatils pls xhumana nathi.)

(Yebo, ukwenza ngokwezifiso nakho kuvunyelwe, inqobo nje uma unganikeza umdwebo onemininingwane, ikakhulukazi izingxenye ezithile njengama-bearings.)

Injini yodaka ye-downhole ngayinye ihlolwa ebhentshini lokuhlola elichwepheshile futhi injini yodaka edilivwe iqinisekiswa ngo-100%, bese umbiko wokuhlola uzonikezwa wena.

Injini ngayinye yodaka ye-downhole ingasebenza ngokuqhubekayo izinsuku eziyi-7 ~ 10 ngesimo esihle sokusebenza nokusebenza okufanele.

Kunjalo, isevisi eku-inthanethi ngemuva kokuthengisa iyatholakala noma nini.
