I-downhole stabilizer ucezu lwempahla ye-downhole esetshenziswa ekuhlanganiseni kwembobo engezansi (BHA) yentambo yokubhoboza. Izinzisa i-BHA emgodini ukuze kugwenywe ukuchezuka okungahlosiwe, ukudlidliza, nokuqinisekisa ikhwalithi yembobo ebholwayo. Yakhiwe ngomzimba oyisilinda ongenalutho kanye nezinsimbi eziqinisayo, zombili ezenziwe ngensimbi enamandla amakhulu. Ama-blades angaba aqondile noma asontekile, futhi anobuso obuqinile bokumelana nokugqoka.

Kukhona ikakhulukazi izinhlobo ezintathu zokuzinza zokumba ezisetshenziswa endaweni kawoyela namuhla.

1. I-Integral stabilizer, eyenziwe ngomshini ngokugcwele ocezu olulodwa lwensimbi. Lolu hlobo luvame ukujwayelekile futhi lusetshenziswa kabanzi.

2. I-stabilizer ye-sleeve eshintshwayo, lapho izindwani zitholakala kumkhono, obese ugoqwa emzimbeni. Lolu hlobo lungakwazi ukonga uma zingekho izindawo zokulungisa ezitholakala eduze nendawo yokumba.

3. Ama-Welded blades stabilizer, lapho izindwani zishiselwa khona emzimbeni. Lolu hlobo ngokuvamile alwelulekwa ngemithombo kawoyela ngenxa yezingozi zokulahlekelwa ama-blade, kodwa lusetshenziswa njalo lapho kubholwa imithombo yamanzi noma ezindaweni zikawoyela ezingabizi kakhulu.

Ngokuvamile ama-stabilizers angu-2 kuya ku-3 afakwa ku-BHA, kuhlanganise neyodwa engaphezulu nje kwe-drill bit (near-bit stabilizer) kanye neyodwa noma amabili phakathi kwamakholomu okubhoboza (izinzamisi zezintambo).

Incazelo:

I-PLATO ulayini ophelele wezinzalo zokumba imigodi ukuze kwandiswe izinga lokungena nokulawula izinkinga zokuchezuka kwemigodi. Zonke lezi ziqinisi (okuhlanganisa uhlobo lwebhithi yokubhoboza, uhlobo lwentambo yokubhoboza, i-spiral blade, i-straight blade, i-integral blade, i-welded blade, uhlobo lomkhono, nezinhlobo zensimbi engenazibuthe) zenzelwe ukuhlangabezana nokulawulwa kwekhwalithi okuqinile kanye namazinga okuqinisekisa ikhwalithi (API SPEC .). Wonke ama-alloy stabilizers akhiqizwa ngensimbi ye-AISI 4145H eguquliwe ephethwe ukushisa ukuze kube nezinhlobonhlobo zokucushwa nosayizi bembobo.

Izici:

1. Osayizi nokucushwa kungenziwa ngokwezidingo zomsebenzisi, okuhlanganisa osayizi be-blade, ukuxhumana, nezinhlobo zezinto.

2. Konke ukuxhumeka kwezinzile kungalungiswa njengebhokisi le-xbox, njenge-pin x box, noma njengoba u-opharetha edinga.

3. I-Welded blade eqondile yokumba izinto ezithambile.

4. Uhlobo lomkhono oluvumela ukufakwa kwempahla encane ezindaweni ezikude.

5. I-Integral spiral blade evumela ukuthintana kwezimbobo ezingu-360° ukuze kusetshenziswe amatshe aqinile.

6. Iziqinisi ezingezona uzibuthe zezinhlelo zokusebenza ezidinga ukuhlukaniswa kazibuthe.

Umdwebo:

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). Ngemva kokuthi uketshezi olumba ngomfutho ophezulu lungena 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.
