I-hydraulic oscillator ikakhulu inamacandelo amathathu oomatshini:
1) icandelo elingaphantsi elishukumayo;
2) inxalenye yamandla;
3) ivalvu kunye nenkqubo yokuthwala.
I-oscillator ye-hydraulic isebenzisa i-longitudinal vibration eyivelisayo ukuphucula ukusebenza kakuhle kokudluliselwa kobunzima bokubhola kunye nokunciphisa ukungqubana phakathi kwesixhobo sokubhola esisezantsi kunye ne-wellbore. Oku kuthetha ukuba i-oscillator ye-hydraulic ingasetyenziswa kwiindlela ezahlukeneyo zokubhola. , ingakumbi ekubholeni kwicala elibhekiselele kusetyenziswa izixhobo zokubhola zamandla ukuphucula ukudluliselwa kobunzima kwi-bit, ukunciphisa amathuba okunamathela kwendibano yesixhobo sokubhola, kunye nokunciphisa ukungcangcazela kwe-torsional.
Umgaqo wokusebenza we-hydraulic oscillator
Inxalenye yamandla ibangela utshintsho oluqhubekayo kuxinzelelo oluphezulu ukuze lusebenze kwi-spring nipple, nto leyo ebangela ukuba i-spring nipple icinezele i-inner spring rhoqo, nto leyo ebangela ukungcangcazela.
Uxinzelelo lolwelo oludlula kwi-sub-joint lutshintsha rhoqo, lusebenza kwi-spring ngaphakathi kwi-sub-joint. Ngenxa yokuba uxinzelelo ngamanye amaxesha luphezulu kwaye ngamanye amaxesha luncinci, i-piston ye-sub-joint iphinda-phinda phantsi kwe-axial action yoxinzelelo kunye ne-spring. Oku kubangela ukuba ezinye izixhobo zokubhola eziqhagamshelwe kwisixhobo ziphinde zijikeleze kwicala le-axial. Ekubeni ucinezelo lwe-spring lusebenzisa amandla, xa amandla ekhutshwa, i-75% yamandla iyehla, ibhekise kwicala le-drill bit, kwaye i-25% eseleyo yamandla iye phezulu, ibhekise kude ne-drill bit.
I-hydraulic oscillator ibangela ukuba izixhobo zokumba phezulu nasezantsi zivelise intshukumo ejikelezayo ende kwi-wellbore, ukuze i-static friction yexeshana yezixhobo zokumba ezantsi kwe-wellbore itshintshe ibe yi-kinetic friction. Ngale ndlela, ukumelana ne-frictional kuncitshiswa kakhulu, ngoko ke isixhobo sinokunciphisa ngempumelelo impembelelo ebangelwa yi-wellbore trajectory. I-drilling tool dragging ephumayo iqinisekisa i-WOB esebenzayo.
Kukho ulwalamano oluchanekileyo phakathi kwesantya sokungcangcazela kunye nesantya sokuhamba kwesixhobo, uluhlu lwamaza: 9 ukuya kwi-26HZ. Uluhlu lokukhawulezisa lwempembelelo yesixhobo ngoko nangoko: ngokuphindwe ka-1-3 ukukhawulezisa komxhuzulane.
