I-oscillator ye-hydraulic ikakhulukazi iqukethe izingxenye ezintathu zemishini:
1) isigaba esincane esinyakazayo;
2) ingxenye yamandla;
3) i-valve kanye nohlelo lokuthwala.
I-oscillator ye-hydraulic isebenzisa ukudlidliza kwe-longitudinal ekukhiqizayo ukuthuthukisa ukusebenza kahle kokudluliselwa kwesisindo sokubhoboza nokunciphisa ukungqubuzana phakathi kwethuluzi lokubhoboza elingezansi kanye ne-wellbor. Lokhu kusho ukuthi i-oscillator ye-hydraulic ingasetshenziswa ngezindlela ezahlukene zokubhoboza. , ikakhulukazi ekubhobozeni okuqondisiwe kusetshenziswa amathuluzi okubhoboza amandla ukuthuthukisa ukudluliselwa kwesisindo ku-bit, ukunciphisa amathuba okunamathela kwenhlangano yamathuluzi okubhoboza, nokunciphisa ukudlidliza kwe-torsional.
Isimiso sokusebenza se-oscillator ye-hydraulic
Ingxenye yamandla ibangela izinguquko eziqhubekayo ekucindezelekeni okuphezulu ukuze isebenze engonweni yesipilingi, okubangela ukuthi ingono yesipilingi icindezele njalo isipilingi sangaphakathi, okubangela ukudlidliza.
Umfutho woketshezi oludlula ku-sub-joint ushintsha njalo, usebenza entwasahlobo ngaphakathi kwe-sub-joint. Ngenxa yokuthi umfutho ngezinye izikhathi uphakeme futhi ngezinye izikhathi uncane, i-piston ye-sub-joint iphinda i-axial ngaphansi kwesenzo esiphindwe kabili somfutho kanye nentwasahlobo. Lokhu kubangela ukuthi amanye amathuluzi okubhoboza axhunywe kuthuluzi aphinde abuyele ohlangothini lwe-axial. Njengoba ukucindezela kwentwasahlobo kudla amandla, lapho amandla ekhishwa, u-75% wamandla uya phansi, ubhekise ohlangothini lwe-drill bit, kanti u-25% wamandla asele uya phezulu, ubhekise kude ne-drill bit.
I-oscillator ye-hydraulic ibangela ukuthi amathuluzi okubhoboza phezulu naphansi akhiqize ukunyakaza okuphindaphindayo okude emgodini womthombo, ukuze ukungqubuzana kwesikhashana okungaguquki kwamathuluzi okubhoboza phansi komthombo kushintshe kube ukungqubuzana kwe-kinetic. Ngale ndlela, ukumelana kokungqubuzana kuncishiswe kakhulu, ngakho-ke ithuluzi linganciphisa ngempumelelo umthelela obangelwa umzila we-wellbore. Isici sokuhudula ithuluzi lokubhoboza esiphumelayo siqinisekisa i-WOB esebenzayo.
Kukhona ubudlelwano obuqondile phakathi kwemvamisa yokudlidliza kanye nesilinganiso sokugeleza ngethuluzi, ububanzi bemvamisa: 9 kuya ku-26HZ. Ububanzi bokusheshisa bomthelela wethuluzi osheshayo: izikhathi ezingu-1-3 zokusheshisa kwamandla adonsela phansi.
