I-torque impact generator ye-dth hammer isetyenziswe ngokubambisana ne-PDC drill bit.Indlela yokuqhekeza amatye isekwe kwimpembelelo yokutyumza nokujikeleza ukucheba ukumila kwamatye.Umsebenzi ophambili kukuqinisekisa umgangatho womzimba wequla ngelixa uphucula isantya sokumba oomatshini.
i-longitudinal kunye ne-torsional) iziganeko ezinokuthi zenzeke ngexesha lokuhamba kwe-downhole drill bit, igcina i-torque ye-drill drill yonke izinzile kwaye ilungelelanise, kwaye iguqule ngobuchule amandla olwelo odakeni kwi-torsional, high-frequency, i-uniform kunye nefuthe elizinzileyo lomatshini. amandla kwaye idlulisela ngqo kwi-PDC drill bit, ukuze i-drill bit kunye nezantsi kwequla zihlale zigcina ukuqhubeka.
Iimpawu zeDTH zesando zemveliso:
1) Olu hlobo lwesando se-dth lwenzelwe inkqubo yokuvuthela eyomeleleyo, enokusebenzisa zonke iigesi zoxinzelelo oluphezulu lokukhutshwa kwe-slag.
2) Yenzelwe iplagi yokulawula umoya, enokuthi ilungelelanise umoya osetyenziselwa ukukhutshwa kwe-slag ngokobunzima bamatye ohlukeneyo, ukuxhathisa ukunxiba, kunye nokuqhuba ukufezekisa eyona mpembelelo ibalaseleyo yokukhupha i-slag kwaye ngaloo ndlela ifezekiseke kakuhle kakhulu.
3) Ulwakhiwo lulula, kukho iindawo ezimbalwa, kunye nokusetyenziswa kweendawo ezinqabileyo zokunxiba kwenza ixesha lokusebenza kwesando se-dth libe lide.
4) Umdibaniso wangaphambili uthatha intambo yeentloko ezininzi ukuze udibanise ne-cylinder yangaphandle, okwenza kube lula kwi-dth hammer ukukhupha i-drill bit.
Umda wokusetyenziswa kweehamile ze-dth:
Imigodi, iikwari, oohola bendlela kunye nezinye iiprojekthi zigrumba imingxuma eqhumayo, imingxuma yezithintelo, ukuqinisa intaba, i-anchoring kunye neminye imingxunya yobunjineli, imingxuma yokupholisa umoya we-geothermal, imingxuma yamaqula amanzi, njl.
Xa isando se-dth sisebenza ngokuqhelekileyo, i-drill bit ichasene nomzantsi womngxuma, kwaye i-dth hammer energy esuka kwi-piston idluliselwa ngokuthe ngqo ezantsi komngxuma ngokusebenzisa i-drill bit.Phakathi kwabo, ibhloko yesilinda ayimelani. umthwalo wempembelelo.Xa isando se-dth siphakamisa isixhobo sokugaya, asivumeli ukuba ibhloko ye-cylinder imelane nomthwalo wempembelelo.Ngaphezu koko, isakhiwo siyasebenza kwaye sinokufezekiswa ngokubethelwa. Oku kungenxa yokuba i-drill bit kunye ne-piston slide phantsi ngobunzima bazo kumgama othile, kunye nokugqobhoza kokukhusela emoyeni kubonakaliswe, ngoko ke uxinzelelo oluvela kwindlela yokulungelelanisa luyaziswa. kwibhloko yesilinda, kwaye i-orifice esembindini ye-drill bit kunye nepiston ibalekela emoyeni, ibangela ukuba ihamile ye-dth iyeke ukusebenza ngokwayo.
