I-Casing Scraper isetshenziselwa ukuhlanza usimende, udaka, izinhlamvu ezigxilile, ukugqwala, isikali sokugaya, upharafini, ama-perforation burrs nezinye izinto ezivela ngaphakathi kwezindonga ze-casing. Ukugcina i-casing ye-I. D. ihlanzekile kubalulekile ekusebenzeni kwawo wonke amathuluzi asetshenziselwa ukumba umthombo. Ngokufanayo, amapaki namathuluzi afanayo kufanele abe nendawo ehlanzekile yokubamba. Izinto zangaphandle ezindongeni ze-casing ngokuvamile zizobangela ukuthi la mathuluzi kube nzima ukusebenza.

I-Casing Scraper ikhiqizwa ngocezu oluqinile lwensimbi ephethwe ukushisa. Ama-scraper blades angena ezindaweni ezihlala ngomshini futhi agcinwe ngokuvikelekile umgcini we-dovetail kanye ne-spacer. Ama-scraper blades afaka ama-grooves e-helical esandleni sokunxele futhi abhekane kanzima ukuze enze umsebenzi omkhulu. Kunama-blade anele emzimbeni wokuklwebha ngokuphelele i-casing surface ngaphandle kokuzungezisa ithuluzi.

Ukuxhumana okujwayelekile ku-Casing Scraper yi-API Reg., Ibhokisi ne-Pin. Lokhu kuvumela i-scraper ukuthi ifakwe kuntambo yokubhoboza phakathi kwe-bit kanye ne-bit sub. I-bit iqhutshwa ngaphansi kwe-scraper ukuze isebenze njengesiqondiso futhi ivimbele ukuxhuma umgodi wokujikeleza nge-scraper.

I-API Drilling Chinese Downhole Drilling Mud Motor iwuhlobo lwethuluzi lokumba imigodi elinikezwa udaka. Udaka olusuka empompini yodaka lungena emothini ngendlela ye-bypass valve, bese ukwehla kwengcindezi phakathi kwe-motor inlet kanye ne-outlet kudalwe, ukwehla kwengcindezi okunjalo kuzoshayela i-motor rotator ukuthi ijikeleze, 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 ye-sidetrack kanye nokusebenza kahle kwequla, Ukusebenza kwe-Coiled Tubing, 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

I-rota ehlukahlukeneisilinganiso se-tion 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.
