Ntuj thiab qhov chaw ntawm Drift
Lub Drift yog kev sib hloov ntawm sab nrauv gimbal vim lub ntiaj teb kev sib hloov tau hnov thiab tsis zoo ntawm lub cev. Drift yog qhia nyob rau hauv (degrees ib teev) thiab muaj peev xwm nyob ntawm 10 mus rau 100 (degrees / teev).
Feem ntau, drift qhov tseem ceeb yuav muaj raws li hauv qab no:
- 0.5℃rau 1℃ib feeb rau pheej yig gyros
- ob peb degrees ib teev rau kev taw qhia gyros
- 1/100th℃ib teev rau inertial gyros siv gimbal flotation
- 1/1000th℃ib teev rau qee qhov inertial gyros nrog spherical spinning rotors txhawb los ntawm hluav taws xob teb
Kev sib hloov ntawm lub ntiaj teb ua rau pom tseeb drift. Lub torque uas yuav ua rau drift yuav raug muab cais ua ob pawg loj.
Yuam kev Torque, xws li gimbal yuam kev, rau qhov kev hloov kho lossis kev them nyiaj yuav raug siv.
Uncertainty Torque yog random feem ntawm drift uas dais tsis muaj kev sib raug zoo nrog cov khoom siv. Lub drift vim qhov yuam kev torques yog peb hom: Nonacceleration rhiab drift, Feem ntau tshwm sim los ntawm elastic lossis sib nqus torques.
Acceleration rhiab heev drift: Feem ntau tshwm sim los ntawm huab hwm coj unbalance.
Acceleration rhiab heev
Lwm qhov chaw ntawm qhov tsis sib haum ntawm qhov tsis sib haum xeeb yuav yog qhov kub thiab txias - rhiab torques vim qhov sib txawv nthuav dav - torques vim qhov tsis sib xws ntawm lub hauv paus axes thiab lub log nrawm hloov.
Qhov random drift yog vim qhov tsis paub tseeb me me xws li cov uas tshwm sim los ntawm cov suab nrov, kev sib txhuam, thiab kub gradients, tag nrho cov no yog lub sijhawm hloov pauv. Random drift feem ntau txiav txim siab los ntawm kev txheeb xyuas kev txheeb xyuas ntawm ntau qhov kev sim drift.
Kev txiav txim siab tseem ceeb yuav tsum tau nyob hauv siab thaum siv Gyro Wireline cuab yeej hauv Roj & Gas Wells
Gyroscopes yog qhov rhiab heev rau kev vibration, yog li lub gyro tib txhaj tshuaj yuav tsum tau khiav thiab muab rov qab rau ntawm ib lub xov tooj.
Lub gyroscope tuaj yeem txav deb ntawm nws qhov kev taw qhia thaum khiav hauv lub qhov. Thaum cov cuab yeej rov qab los, nws yuav tsum raug kuaj xyuas, thiab kev kho kom haum rau cov kev nyeem tau los ntawm kev soj ntsuam. Gyro txhaj tshuaj ib zaug feem ntau yog siv los taw qhia cov cuab yeej deflecting ze ntawm lub casing.
Gyro Multi-Kev txhaj tshuaj yog siv rau hauv cov qhov rooj kom tau txais cov kev tshawb fawb raws li qhov ntev ntawm qhov dej. Kev txhaj tshuaj magnetic multi- tsis tuaj yeem siv vim muaj kev cuam tshuam nrog lub ntiaj teb magnetic teb tshwm sim los ntawm kev sib nqus ntawm lub casing.
Tus kws soj ntsuam kev taw qhia yuav tsum tau taug qab qhov tob ntawm qhov ua ntej - teem sijhawm ua daim duab. Tsuas yog cov kev txhaj tshuaj tau txhaj rau ntawm qhov tob paub thaum cov yeeb nkab nyob ruaj ruaj yuav raug kaw.
Thaum cov tshuaj tua ntau- rov qab los, cov yeeb yaj kiab tau tsim, thiab cov txiaj ntsig kev tshawb fawb tau nyeem. Nyob rau hauv rooj plaub ntawm ob qho tib si - txhaj tshuaj thiab ntau - cov cuab yeej txhaj tshuaj, yuav tsum muaj qhov chaw nruab nrab kom txaus kom lub cuab yeej ua kom raug raws li qhov zoo.
Raws li ib tug saum toj kawg nkaus -tier ntiaj teb no chaw tsim tshuaj paus ntawm gyro soj ntsuam cov cuab yeej, Tuam Tshoj Vigor nkag siab txog lawv lub luag hauj lwm tseem ceeb nyob rau hauv downhole ua hauj lwm. Txij li xyoo 2015, peb tau nqis peev tsis tu ncua hauv R & D thiab txhim kho peb cov tshuab gyro inclinometer. Los ntawm 2025, Vigor cov cuab yeej tau raug xa mus thoob plaws cov roj av hauv Central Asia, Europe, thiab Africa, xa cov ntaub ntawv raug siab - qhov tseeb uas txo qis tsis yog - lub sijhawm tsim khoom rau peb cov neeg siv khoom.
Vigor Pro-Guide Series Gyro Inclinometerexcels nyob rau hauv kev tswj drift qhov tseem ceeb los ntawm lub ntiaj teb no ua cov ntaub ntawv them nyiaj algorithm, kom ntseeg tau tias tsawg deviation thiab xa cov ntaub ntawv txiav txim siab heev. Tsis tas li ntawd, piv rau lwm hom gyro inclinometers, Pro-Cov Lus Qhia Series yuav tsum tau saib xyuas yooj yim dua thiab muaj kev ua haujlwm zoo dua qub- cov engineers feem ntau piav qhia nws li "rugged." Nws cov nqi thauj khoom qis thiab kev saib xyuas, nrog rau kev ua haujlwm ntev, yog qhov laj thawj tseem ceeb vim li cas nws tau txais kev lees paub zoo los ntawm cov neeg siv khoom.
Peb pab pawg kws tshaj lij tau rov ua dua ntawm - cov kev pabcuam nkag rau hauv chaw, tau txais kev lees paub dav dav.
Peb kuj zoo siab tshaj tawm tias Tuam Tshoj Vigor tau ua tiav qhov kev sim ua tiav rau Kev Nkag Mus Rau Thaum Drilling (LWD), Gyro Thaum Drilling (GWD), thiab Kev Ntsuas Thaum Drilling (MWD), thiab tam sim no nquag qhia cov kev daws teeb meem siab heev rau kev lag luam.
Yog xav paub ntxiv txog yuav ua li cas peb ProGuide ™ Series thiab lwm yam kev siv thev naus laus zis thev naus laus zis tuaj yeem txhim kho koj qhov kev ua haujlwm zoo thiab cov ntaub ntawv raug, thov tsis txhob yig tiv tauj peb pab pawg kws tshaj lij engineering. Peb yeej ib txwm npaj los muab koj cov lus qhia thiab kev pabcuam tshaj lij tshaj plaws rau koj.
