Av nkos motorsyog ib qho tseem ceeb enabling technology rau directional thiab kab rov tav drilling.
Dab tsi txawv ntawm Mud motors muaj?
1. Cov Tsav Tsheb Zoo Tshaj Plaws hloov hydraulic zog los ntawm cov dej ntws ntws mus rau hauv lub tshuab fais fab kom tig lub ntsis ntawm nws tus kheej los ntawm kev sib hloov ntawm qhov chaw. Lawv muaj lub lobed rotor uas eccentrically rotates nyob rau hauv ib tug roj hmab stator. Raws li cov av nkos ntws los ntawm, lub rotor nce mus rau hauv stator kab noj hniav, tsim torque. Cov motors no muab siab torque tso zis zoo tagnrho rau directional drilling, cia ceev kick-off ntawm ntsug thiab drilling tsim tus nqi siab tshaj 30 degrees ib 100 ko taw.
2. Turbodrills muaj nuj nqi raws li lub turbine es tsis txhob muaj qhov zoo ntawm qhov txav ntawm lub lobe mechanism. Cov av nkos ntws dhau los ua ib qho axial turbine uas ua rau lub zog ntawm qhov chaw tsav tsheb me ntsis. Turbodrills tsim kom muaj kev nrawm dua thiab tsawg dua torque piv rau cov motors hloov chaw. Lawv qhov me me ntawm qhov txav mus los kuj ua rau lawv txhim khu kev qha nyob rau hauv high-temperature, deviated qhov dej thaum lubricity tsis zoo. Turbodrills ua tau zoo nyob rau hauv tawv, abrasive formations.
Dab tsi yog cov ntsiab lus tseem ceeb ntawm kev ua haujlwm ntawm Mud motor?
1. Torque Output - Lub zog torque uas tsim los ntawm ntu fais fab txiav txim siab npaum li cas lub cev muaj zog tuaj yeem tig cov laum cov khoom thiab kov yeej kev sib txhuam. Kev tshem tawm cov motors ua kom muaj lub zog siab thaum turbodrills muab qis dua torque ntawm kev nrawm dua.
2. Khoov lub kaum sab xis - Lub tsev khoov khoov dictates lub kaum sab xis deflection lub cev muaj zog tuaj yeem ua rau txoj hlua tho rau lub tsev, xa me nyuam rov los yog tig lub qhov dej. Khoov cov ces kaum ntawm 0.5 mus rau 3 degrees feem ntau muaj.
3. Horsepower - Cov kev ntsuam xyuas lub siab horsepower qhia tau hais tias yuav tsum tau tso tawm thoob plaws qhov kev khiav hauj lwm RPM raws li cov twj tso kua mis thiab cov nqi ntws. Ntau horsepower ua rau siab dua ROP drilling.
4. Bearing Assembly - Thrust thiab radial bearings tiv taus downhole loads thiab rotations nyob rau hauv siab kub nyob rau hauv lub hwj chim seem. Premium bearings txhim khu kev ntseeg tau thiab khiav lub neej.
Yam dab tsi cuam tshuam rau cov av nkos thiab cov av nkos siab xav tau rau cov av nkos?
1. Nyhav ntawm ntsis - Hnyav WOB yuav tsum tau nce ntws thiab siab tig lub ntsis thiab kov yeej kev sib txhuam tsis zoo.
2. Ntsis Nozzle Sizes - Ib qhov loj dua tag nrho cov nozzle cheeb tsam tso cai rau cov nqi ntws ntau dua thiab hydraulic HP tab sis kuj yuav tsum muaj ntau dua circulating pressures.
3. Drill String Friction - Ntev ntev thiab hnyav dua laum hlua los yog lub kaum sab xis zoo ua rau muaj kev sib txhuam siab uas yuav tsum tau kov yeej.
4. Formation Hardness – Harder formations thov kom siab dua ndlwg thiab pressures kom ua tau ib tug zoo xyaum me ntsis ROP.
5. Kub - Kub kub downhole kub degrade lubricity thiaj li xav tau ntau txaus rau bearing txias thiab tiv thaiv.
Ua tib zoo sib phimAv nkos motormuaj peev xwm thiab kev khiav hauj lwm tsis rau qhov drilling tej yam kev mob ua kom ntseeg tau, zoo tshaj plaws kev ua tau zoo nyob rau hauv kev taw qhia drilling ua hauj lwm.
