Ubume kunye nomgaqo wokusebenza we-hydraulic oscillator

Umgaqo osebenzayo we-hydraulic oscillator

Inxalenye yamandla ibangela utshintsho lwamaxesha ngamaxesha kuxinzelelo oluphezulu ukuze lusebenze kwingono yasentwasahlobo, ibangela ukuba incono yasentwasahlobo icinezele ngokuqhubekayo intwasahlobo yangaphakathi, ibangele ukungcangcazela.

Uxinzelelo lwe-fluid edlula kwi-sub-joint lutshintsha rhoqo, lusebenza entwasahlobo ngaphakathi kwe-sub-joint. Ngenxa yokuba uxinzelelo ngamanye amaxesha luphezulu kwaye ngamanye amaxesha luncinci, i-piston ye-sub-joint ibuyisela i-axially phantsi kwezenzo ezimbini zoxinzelelo kunye nentwasahlobo. Oku kubangela ezinye izixhobo zokugaya ezidityaniswe kwisixhobo ukuze ziphinde zibuyele kwicala le-axial. Ekubeni ukunyanzeliswa kwentwasahlobo kudla amandla, xa amandla ekhutshwa, i-75% yamandla ihla, ikhomba kwicala le-drill bit, kwaye i-25% eseleyo yamandla iphezulu, ikhomba kude ne-drill bit.

I-oscillator ye-hydraulic ibangela ukuba izixhobo zokugaya phezulu naphantsi zivelise i-longitudinal reciprocating motion kwi-wellbore, ukwenzela ukuba i-friction ye-static yesikhashana yezixhobo zokugaya emazantsi equla zitshintshe zibe yi-kinetic friction. Ngale ndlela, ukuxhathisa i-frictional kuncitshiswe kakhulu, ngoko ke isixhobo sinokunciphisa ngempumelelo impembelelo ebangelwa yi-wellbore trajectory. Isixhobo esinesiphumo sokutsala isixhobo siqinisekisa i-WOB esebenzayo.

Kukho ubudlelwane bomgca phakathi kokuphindaphinda kwe-vibration kunye nesantya sokuhamba ngesixhobo, uluhlu lwamafrikhwensi: 9 ukuya kwi-26HZ. Uluhlu olukhawulezayo lwempembelelo yesixhobo ngokukhawuleza: amaxesha angama-1-3 ukukhawuleza komxhuzulane.
