Yintoni iMoto yodaka?

IInjini yokuFuduka eNgcono (PDM), okwaziwa ngokuba yi“injini yodaka,”yindawo ebalulekileyoisixhobo sokugrumbaisetyenziswa kwimisebenzi yeoyile negesi. Iguqula amandla e-hydraulic avela kulwelo lokugrumba (udaka) abe kukujikeleza koomatshini ukuze kuqhutywe i-drill bit, nto leyo eyenza ukuba ibaluleke kakhulu ekugrumbeni kwicala elithile, emigodini ethe tye, nasekuphambukiseni umkhondo.

I. Ulwakhiwo kunye noMgaqo-siseko wokuSebenza

1. Izinto eziphambili

Ivalvu yokudlula: Ivumela ukujikeleza kolwelo ngexesha lokukhubeka ukuze kuthintelwe ukunyuka koxinzelelo.

Icandelo leMoto: Iyunithi yamandla engundoqo, equkai-stator(ityhubhu ene-elastomer) kunyei-rotor(isikrufu sesinyithi esijikelezileyo).

I-Universal Joint: Iguqula intshukumo engaqhelekanga yerotor ibe kukujikeleza okucwangcisiweyo.

Ishaft yokuqhuba: Ithumela i-torque kwi-drill bit, ixhaswa zii-bearing assemblies zemithwalo ye-axial/radial.

2.Umgaqo Wokusebenza

Ulwelo lokubhola olunoxinzelelo oluphezulu lungena kwi-motor, nto leyo enyanzela i-rotor ukuba ijikeleze ngaphakathi kwi-stator ngentshukumo yeplanethi (ukuqengqeleka + ukujikeleza).

Ukujikeleza kwerotor kudluliselwa nge-universal joint kunye ne-drive shaft ukuya kwi-drill bit.

Isantya sokuhamba (Q) xa kuthelekiswa ne-RPM (N):

N=qQ×ηv.

Q: Izinga lokuhamba kwamanzi (L/s)

qUkufuduka ngokujikeleza ngakunye (L/rev)

ηvUkusebenza kakuhle kwevolumu (ngesiqhelo yi-80–90%)

II. Ukuhlelwa kweePDM

1. Ngoyilo

I-Single-Lobe PDM (uqwalaselo lwe-1:2): Isantya esiphezulu, i-torque ephantsi (umz., yokubhoboza ngemingxunya emincinci).

I-Multi-Lobe PDM (umz., uqwalaselo lwe-5:6): Isantya esiphantsi, i-torque ephezulu (umz., kwiibhithi ezinkulu okanye ii-hard formations).

2. Ngesicelo

I-PDM esemgangathweni: Isetyenziswa kwimithombo ethe nkqo okanye elula.

I-Bent Housing PDM: Inendawo egobileyo engaguqukiyo (umz., 1°, 1.5°, 2°) yokulawula kwicala.

I-Hybrid Turbine-PDM: Idibanisa i-RPM ephezulu (i-turbine) kunye ne-torque ephezulu (PDM).

III. Iiparameters zeNtsebenzo ePhambili

IV. Ukukhetha kunye nezicelo

1. Iikhrayitheriya zokukhetha

Ukuqina koBume: Iifomyula eziqinileyo zifuna ii-PDM ezininzi ukuze kubekho i-torque ephezulu.

Indlela Yokuhamba Komthombo: Imithombo ekhokelayo ifuna ii-PDM ezigobileyo.

Ulwelo lokubhola: Udaka olusekelwe kwioyile lufuna ii-elastomers ezimelana neoyile (umz., i-HNBR); Iindawo ze-H₂S zifuna izinto eziluncedo kakhulu.

2. Izicelo eziqhelekileyo

Ukubhola okuthe tye: Isetyenziswa kwiinkqubo ze-MWD/LWD ukuze kuqhutywe ngendlela echanekileyo.

Ukulandelela ecaleni kunye nokusebenza: Ibonelela ngokujikeleza emva kokuphuma kwekhava.

Iimithombo ezinzulu/ezinzulu kakhulu: Ifuna ii-stators ezinobushushu obuphezulu kunye nezinto eziqinileyo.

V. Ukusilela Okuqhelekileyo kunye noLondolozo

VI. Iindlela Zexesha Elizayo

1.IiPDM ezikrelekrele: Izinzwa ezidityanisiweyo zokujonga i-torque/ubushushu/ukungcangcazela ngexesha langempela.

2.Izixhobo Eziphambili: Iirotha ezifakwe i-nanocoated, ii-elastomers ezingama-200°C+ ngaphezulu.

3.Iinkqubo zeHybrid: Iindidi zePDM + zeturbine zeefomyula ezintsonkothileyo.

I-Landrill inokubonelela ngeentlobo zeemoto zodaka (PDMS) ezisemgangathweni ophezulu. Ukuba unjaloUkuba unomdla kubo, nceda uzive ukhululekile ukunxibelelana nathi. Singakuthumelela iinkcukacha ezithe vetshe.
