I-downhole stabilizer sisiqwenga sesixhobo somngxuma osezantsi esisetyenziswa kwindibano esezantsi yomngxuma (BHA) womtya wokubhola. Izinzisa ngoomatshini i-BHA kumngxuma wokutsala amanzi ukuze kuthintelwe ukuphambukisa ngokungeyonjongo, ukungcangcazela, kunye nokuqinisekisa umgangatho womngxuma ogrunjwayo.Uwenziwe ngumzimba wecylindrical ongenanto kunye neebhleyidi zokuzinzisa, zombini zenziwe ngentsimbi yokuqina okuphezulu. Iiblades zinokuba zithe tye okanye zijikelezwe, kwaye zinobunzima bokumelana nokunxiba.

Kukho ubukhulu becala ezintathu iintlobo zokuzinzisa ukomba ezisetyenziswa kwindawo yeoli namhlanje.

1. I-Integral stabilizer, eyenziwa ngokupheleleyo kwintsimbi enye. Olu hlobo luvame ukuba luqhelekileyo kwaye lusetyenziswe ngokubanzi.

2. I-replaceable sleeve stabilizer, apho ii-blades zibekwe kwi-sleeve, ethi ke ikrwelwe emzimbeni. Olu hlobo lunokuba noqoqosho xa kungekho zixhobo zokulungisa ezifumanekayo kufutshane nomgodi wokugrunjwa.

3. I-Welded blades stabilizer, apho iincakuba zidityaniselwe emzimbeni. Olu hlobo aluqhelekanga ukucetyiswa kwimithombo yeoli ngenxa yeengozi zokulahleka kwee-blades, kodwa isetyenziswa rhoqo xa kugaywa amaqula amanzi okanye kwiindawo eziphantsi kwe-oyile.

Ngokuqhelekileyo i-2 ukuya kwi-3 i-stabilizers ifakwe kwi-BHA, kubandakanywa enye ngaphezu kwe-drill bit (i-ad-bit stabilizer) kunye neyodwa okanye ezimbini phakathi kweekhola zokugaya (i-string stabilizers).

Inkcazo:

I-PLATO umgca opheleleyo we-downhole drilling stabilizers ukwandisa izinga lokungena kunye nokulawula iingxaki zokuphambuka komngxuma. Zonke ezi zinzisi (kubandakanya uhlobo lwebit drill, uhlobo lomtya wokubhola, iblade ejikelezayo, iblade ethe tye, iblade edityanisiweyo, iblade edityanisiweyo, uhlobo lomkhono, kunye neentlobo zentsimbi engenazibuthe) ziyilelwe ukuhlangabezana nolona lawulo lungqongqo lomgangatho kunye nemigangatho yoqinisekiso lomgangatho (API SPEC .). Zonke i-alloy stabilizers zenziwa kwi-AISI 4145H eguqulelwe ngobushushu obutshintshiweyo ngentsimbi yokulungiswa kweendlela ezahlukeneyo kunye nobukhulu bomngxuma.

Iimbonakalo:

1. Ubungakanani kunye nolungelelwaniso lunokuveliswa kwiimfuno zomqhubi, kubandakanywa ubungakanani be-blade, ukudibanisa, kunye neentlobo zezinto eziphathekayo.

2. Lonke uxhulumaniso lokuzinzisa lunokuqwalasela njengebhokisi yebhokisi, njenge-pin x ibhokisi, okanye njengoko ufuna umsebenzi.

3. Iblade edityanisiweyo ethe tye yokwemba izinto ezithambileyo.

4. Uhlobo lomkhono luvumela uluhlu lwezixhobo ezincinci kwiindawo ezikude.

5. I-Integral spiral blade evumela umngxuma oyi-360° ukudityaniswa ukuze isetyenziswe kulwakhiwo oluqinileyo.

6. Uzinzisi olungelomagnetic kwizicelo ezifuna ukwahlulwa kumagnethi.

Umzobo:

I-API Drilling Chinese Downhole Drilling Mud Motor luhlobo lwesixhobo sokugrumba ezantsi esiqhutywa ludaka. Udaka olusuka kwimpompo yodaka lungena kwi-motor ngendlela ye-valve edlulayo, kunye nokuhla koxinzelelo phakathi kwe-motor inlet kunye ne-outlet eyenziwe, ukuhla koxinzelelo kuya kuqhuba i-motor rotator ukuba ijikeleze, kwaye idlulisele i-torque kunye nesantya sokujikeleza kwi-bit by shaft jikelele kunye ne-shaft yokuhambisa. . Ipropathi ye-downhole motor ixhomekeke ikakhulu kwiiparamitha zepropati yayo. Le mveliso isebenzisa itekhnoloji ephezulu kunye nentsha yokugquma ukunqanda ukugquma kweerotha ezibangelwa bubuchwephesha bemveli. Amandla kunye nobomi bayo buphuculwe kakhulu. Isebenza kwi-Horizontal Directional Drilling, ukugrumba okuyintlanganisela, amaqula adibeneyo, amaqula asecaleni kunye nokusetyenzwa kakuhle, ukuSebenza kweTubing eDityanisiweyo, njl.njl.doi-whole yokomba injini

Imoto ephantsi luhlobo lwe-positivement downhole motor(PDM). Emva koxinzelelo oluphezulu lolwelo lokomba lungena kwimotor esezantsi ukusuka kwisiqu sokomba, uxinzelelo lolwelo lunyanzela irotor ukuba ijikelezise ehambisa itorque ukuya kwibhithi ukuphumeza injongo yokomba.

Iindidi ngeendidi zokudityaniswa kwemoto ephantsi komngxuma wobungakanani bequla 1 7/8"~26" kunye ne24 yemilinganiselo engundoqo (echongwa ngedayamitha engaphandle yestator) : 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".

Ifom yesakhiwoibandakanyangqo, ukugoba okukodwa, ukugoba kabini, i-engile enokulungiseka njalo njalo. Uluhlu lweqondo lobushushu elikwaziyo ukumelana nobushushu lubandakanya  250°F (120℃) okanye ngaphantsi kwe-250℉ (120℃), naphakathi kwe-250 ℉(120℃) ukuya kuma-355℉ (180℃). Singakwazi nokubonelela ngazo zonke iinkcukacha kuqukwainjini ekwaziyo ukumelana nodaka esekwe kwi-oyile kunye nenjini ekwaziyo ukumelana nodaka lwamanzi etyuwa.

Iimpawu ezibalaseleyo

Izinga lokujikeleza kunye netorque, ubuchule obuphezulu, uluhlu lokuqukuqela olubanzi, ukusebenza okungenamagingxigingxi, ulungiso olulula, ukuthembeka okuphezulu, ubomi benkonzo ende.

Isicelo esiKhuselekileyo

Amandla awoneleyo kunye nezixhobo eziyilwe ngokukodwa izixhobo ezininzi eziwayo ukuqinisekisa ukusebenza ngokukhuselekileyo kokomba.

Injini eqhelekileyo yomngxuma iqulathe la malungu alandelayo:

(1) Ukudityaniswa kwebhola edadayo okanye ukudityaniswa kwevalvu ye-By-pass

 umngxuma wokomba injini

(Ezinye iiModeli zilapha ngereferensi yakho, iimodeli ezininzi kunye needetils pls qhagamshelana nathi.)

(Ngokuqinisekileyo, ukwenza ngokwezifiso kukwavumelekile, ukuba nje unokubonelela ngomzobo oneenkcukacha, ngakumbi iindawo ezinjengeebheringi.)

Imoto yodaka yomngxuma ngamnye ivavanywa kwibhentshi yovavanyo lobuchule kwaye isithuthi sodaka esisikelweyo siqinisekisiwe nge-100%, emva koko ingxelo yovavanyo iya kunikwa wena.

Umngxuma ngamnye wodaka wemoto unokusebenza ngokuqhubekayo iintsuku ezi-7 ~ 10 ngemeko elungileyo yokusebenza kunye nokusebenza ngokuchanekileyo.

Ewe kunjalo, inkonzo ye-intanethi emva kokuthengisa iyafumaneka nangaliphi na ixesha.
