Umahluko phakathi kwe-MWD kunye ne-LWD?

Umlinganiselo Ngelixa Kusetywayo (MWD): Ushunqulelo lwe “Measurement while Drilling” ngesiNgesi.
Isixhobo esingenazingcingo se-MWD singenza imilinganiselo ngexesha elifanelekileyo ngexesha lenkqubo yokomba, oko kukuthi, xa ukugrumba kungayekwa, udaka lwe-pulse generator luthumela idatha elinganiswe yi-downhole probe kumphezulu, kunye nenkqubo yekhompyutha iqokelela kwaye iqhube i-wellbore yexesha lokwenene. iiparamitha. Kwaye iiparameters zokwakheka. I-MWD inokulinganisa i-angle yokuthambekela, i-azimuth angle, i-angle yobuso besixhobo kunye namandla e-gamma yendalo yokwakheka ngexesha lenkqubo yokomba, kunye nokubonelela ngeeparamitha ze-wellbore ngexesha elifanelekileyo kunye nedatha yokuvavanya ukubunjwa kwamaqula atenxe kakhulu kunye namaqula axwesileyo. Esi sixhobo sisixhobo sobugcisa esiyimfuneko ekuphuculeni isantya sokomba kunye nokuqinisekisa umgangatho wokugrumba kwindlela ethe tyaba nethe tyaba yokomba.

UkuLogging Ngelixa UGcinya (LWD): Ushunqulelo lwe “Log Ngelixa uDrilling” ngesiNgesi.
Eyokuqala umlinganiselo resistivity, kwaye ke neutron, ingxinano, njl Umahluko ilele parameters ukuba ifunyenwe.
I-MWD ubukhulu becala ngumlinganiselo ngelixa kusetwa. Ukulinganisa i-azimuth yequla, ukuthambekela kakuhle, ubuso besixhobo (amandla ombane, umxhuzulane), kunye nokugrumba isikhokelo; I-LWD ilinganisa i-azimuth yequla, ukuthambekela kakuhle, kunye nobuso besixhobo, kunye nokulinganisa ukumelana, i-gamma yendalo, uxinzelelo lomthombo, i-porosity, ubuninzi, njl.

Iiparameters zesixhobo sokuhambisa umqondiso we-downhole ziba yi-pulses okanye amaza oxinzelelo, adluliselwa emhlabeni ngolwelo lokugaya kumbhobho wokubhobhoza njengomqhubi, kwaye ungene kwindawo yomhlaba wenkqubo. Kwinxalenye yomhlaba, umamkeli wesignali ngokuqhelekileyo efakwe kwi-riser uguqula iiparitha kwiimpawu zombane kwaye uzidlulisele kwikhompyutheni ngekhebula lokucoca, ukucacisa, ukuboniswa kunye nokurekhoda. Okwangoku, kukho iinkqubo ezimbini zokuhambisa umqondiso ezisetyenziswayo eziqhelekileyo, enye luhlobo lwe-pulse kwaye enye luhlobo lwamaza oluqhubekayo. Uhlobo lwe-pulse luhlulwe lube luxinzelelo oluhle kunye ne-negative pressure pulse. Inkqubo ye-pulse yoxinzelelo olulungileyo isebenzisa i-plunger ukuvala umjelo we-drilling fluid ngokukhawuleza, okubangela ukuba uxinzelelo lwe-riser luphakame ngokukhawuleza kunye nencopho; Inkqubo ye-pulse yoxinzelelo olubi isebenzisa ivalve yokukhulula ukuvula ngokukhawuleza ukukhupha ulwelo lokubhoboza kwindawo ye-annular, kubangela uxinzelelo lwesikhuphukeli Ukuhla ngesiquphe kubonakala incopho engalunganga. Inkqubo yamaza eqhubekayo isebenzisa isethi ye-stators slotted, i-rotors, kunye ne-drilling fluid ukuvelisa i-low-frequency wave ye-frequency frequency ethile xa idlula, kwaye umqondiso udluliselwa emhlabeni usebenzisa le maza njenge-carrier. Xa usebenzisa izixhobo ze-MWD zohlobo lwe-pulse, misa ngokubanzi impompo kwaye umise i-turntable. Xa usebenzisa i-continuous-wave typeizixhobo ze-MWD, umlinganiselo unokwenziwa ngokuqhubekayo kunye nomsebenzi wokugaya ngaphandle kokumisa umsebenzi wokugaya. I-frequency ye-continuous-wave ngokuqhelekileyo iphezulu kuneyo ye-pulses efanelekileyo kunye ne-negative.

Ngokubanzi, umahluko phakathi kwezi zimbini kukuba i-LWD ibanzi kune-MWD. Ukusetyenziswa ngokubanzi kwe-MWD yiprobe + ibhetri + pulse + battery + gamma, kunye neLWD ngokubanzi yiprobe +ibhetri + ipulse + ibhetri ++ gamma + resistivity.

I-MMRO gyro inclinometer ithatha itekhnoloji yamva nje yeVigor - solid-state

i-gyroscope kunye ne-MEMS i-accelerometer. Yinto enye ye-inclinometer ene-multi-point kunye nomsebenzi wokuzifunela emantla. Isixhobo sineenzuzo zobukhulu obuncinci, ukuchasana kwempembelelo, ukumelana nobushushu obuphezulu, kunye nokuchaneka komlinganiselo ophezulu. Isetyenziswa kakhulu kwindlela yokujonga kakuhle, i-casing window orientation, i-cluster well orientation kunye ne-directional perforation, njl.
