Kuyini imbiza yokubhoboza?

Iimbiza yokubhobozaiguqula amandla angaba khona ngaphakathi kwe-drill enwetshiwe ibe amandla e-kinetic. Ngemva kokuba kwenzeke ukushaqeka, la mandla e-kinetic adlulisela igagasi lamandla ku-drill ebambekile, eliyivula i-drill.

Kunezinhlobo ezintathu zamabhodlela okubhoboza: amabhodlela okubhoboza ngomshini, amabhodlela okubhoboza nge-Hydraulic, kanye namabhodlela okubhoboza ahlanganisiwe e-Hydraulic Mechanical.

Amabhodlela emishini asebenza kusetshenziswa uchungechunge lweziphethu, amaphini, kanye nezindlela zokukhulula. Ibhodlela le-hydraulic lilawula ukuma koketshezi ukuze kufezwe ibhodlela. Ibhodlela elihlanganisiwe le-hydraulic mechanical lihlanganisa imiklamo emibili engenhla nebhodlela.

Imbiza yomshini iyagxumagxuma phezulu uma ukucindezeleka kufinyelela inani elikhethiwe kusengaphambili, futhi iyehla uma amandla okucindezela efika enanini elikhethiwe kusengaphambili. Imbiza izosebenza kuphela ngaphakathi kwenani elinqunyiwe elibekiwe, okufanele ngokuvamile libe kude namandla embiza ngesikhathi sokubhoboza. Ngesikhathi sokubhoboza okuvamile, indawo yembiza yomshini ayithathi hlangothi (ayicindezelwanga) noma inwetshiwe, kodwa kunoma yikuphi akufanele ibe sesimweni sokwehla, njengoba lokhu kungalimaza ngokungadingekile ithuluzi lokubhoboza elingaphansi kanye ne-bit.

Indlela yokukhulula imbiza yemishini ingafakwa ebusweni noma phansi, kuye ngomklamo wembiza yemishini. Kunemiklamo emibili eyinhloko yamajari emishini. Omunye umgomo wokugoqa wentwasahlobo. Imbiza yemishini ilethwa endaweni yomthombo ngemithwalo evuselelwe kanye neyaphansi. Amandla ayo okuvuselela atholakala ngokusebenzisa i-torque variable engu-10-15% kuthuluzi le-downhole, lapho i-torque yokujika kwesobunxele incipha kanye ne-torque yokujika kwesokudla iyanda. I-Daily LI isebenzisa lesi simiso. Omunye umklamo wakhiwe nge-sleeve yesandiso esinezikhala, isixhumi kanye ne-assistant spring. Umthwalo odingekayo ukuze kusebenze imbiza ye-downhole ungancishiswa ngokwandisa ukugeleza kodaka. Imbiza yemishini ye-ANADRILL's EQ isekelwe kulesi simiso, esizochazwa kamuva.

3.I-HydraulicUkubhobozaimbiza

Imbiza ye-hydraulic yakhiwe ngama-piston amabili ahlukaniswe yi-valve. Uma kusetshenziswa amandla okucindezela noma okucindezelayo embiza ye-hydraulic evuselelwe, uketshezi oluku-piston eyodwa luyacindezelwa bese lugeleza luye kwenye i-piston ngaphansi kokumelana okukhulu kokugeleza. Ijubane lokugeleza koketshezi lingalawula isikhathi esidingekayo ukuze ithuluzi livuselele, amandla okwelula noma okucindezelayo makhulu, isikhathi esidingekayo sokuvuselela sifushane, ngaphandle kwalokho isikhathi esidingekayo sokuvuselela side. Ibanga elihanjwayo libizwa ngokuthi i-stroke. Lapho i-stroke ifika endaweni ethile, uketshezi olucindezelwe luzokhishwa ngokuzumayo nge-valve ye-bypass, futhi umnyango uzogijimela episton yesibili enoketshezi olugelezayo, ukuze ingcindezi phakathi kwama-piston amabili ifinyelele ibhalansi ngokushesha. Lapho amandla amakhulu embiza, kulapho amandla okucindezelayo makhulu oketshezi oluku-piston, isikhathi sokuvuselela sifushane, futhi kulapho amandla akhiqizwa yi-excitation emakhulu. Yile ndlela esebenza ngayo imbiza ye-Anadrill Hydraquaker.

Izimo zokuvusa imbiza ye-hydraulic azidingi umkhawulo wokuvusa osethiwe. Isikhathi sokuvuselela, ukuthi kukhiqizwa amandla angakanani ngokuvusa, njll., kuncike kubukhulu bokwelula noma ukucindezela. Uma kushukunyiswa phezulu, amandla okuvusa ayalingana namandla okudonsa. Uma kuhudula kakhulu, kulapho amandla okuvusa aba makhulu khona.

Ngakho-ke, enye inzuzo yezimbiza ze-hydraulic ukuthi zinamandla embiza aguquguqukayo njalo ngaphakathi kwemingcele yazo, kanti enye inzuzo ukuthi zinembobo enkulu kunezimbiza zemishini zamathuluzi angu-6-1/2 “.

Uma imbiza ye-hydraulic isesimweni sokudubula futhi, izophinde idubule uma kunesikhathi esanele sokuqedela ukushaya. Lokhu kunikeza amambiza e-hydraulic inzuzo eyingqayizivele lapho esebenza eMithonjeni ethambekile noma evundlile ngama-engeli aphezulu, lapho umshini wokubhoboza ungase ungakwazi ukusebenzisa amandla okucindezela noma okucindezela anele embizaneni yomshini ngoba ipayipi lokubhoboza lingase libe nokungqubuzana okukhulu. Imbiza ye-hydraulic, ngakolunye uhlangothi, izogcina ivuse ngisho nangaphansi kwamandla amancane okucindezelwa noma okucindezelayo. Vele, lokhu nakho kuyiphutha layo, ingabangela ngengozi futhi iholele ezingozini zezinhlanzi, ikakhulukazi eMithonjeni eqondile.

Ukuvusa njalo imbiza ye-hydraulic kuzobangela ukuthi uketshezi lushise ngokweqile, okunciphisa ukujiya koketshezi, kufinyeze isikhathi salo sokushaya, futhi kubangele ukuthi imbiza ye-hydraulic iqhubekisele phambili ukuvusa ngaphandle kwamandla okudonswa afunekayo. Ngenxa yalokho, amandla okubhoboza ayancishiswa.

Enye yezinzuzo eziyinhloko zamajagi omshini ukuthi asebenza kuphela ngemva kokuba amandla asetshenziswayo esefinyelele umkhawulo obekwe ngaphambilini. Amelana nomsindo kakhulu futhi asebenza isikhathi eside kunejagi le-hydraulic.
