Yintoni iPlug yeBridge?

Iplagi yebhulorho sisixhobo esisetyenziswa kwizicelo ze-downhole kwishishini le-oyile yokomba. I-Downhole ithetha ukuba iplagi yebhulorho isetyenziswe ngendlela engaphantsi komhlaba, oku kuthetha ukuba isetyenziswe kwikakuhle, okanye ngaphantsi komhlaba, ukuthintela ukusetyenziswa kwequla. Iplagi yebhulorho inezicelo ezisisigxina nezexeshana, nto leyo ethetha ukuba ingasetyenziswa ngendlela ephelisa ukuveliswa kwe-oyile ngokusisigxina evela kwiqula egalelwe kulo, okanye inokuveliswa ngendlela eyenza ukuba ibuyiswe kumthombo we-oyile, ngaloo ndlela ivumela ukuba isetyenziswe ngokusisigxina kunye neyexeshana. imveliso esuka equleni ukuze iqalise kwakhona. Zisenokusetyenziswa okwethutyana ngaphakathi kumthombo wamanzi ukuze ziyekei-oyile endalaukusuka ekufikeni kwindawo ephezulu yequla ngelixa kusetyenzwa kulo okanye kunyangwa.

Iiplagi zebhulorho ziqhele ukwenziwa ukusuka kwinani lezinto ezinokuthi nganye ibe nezibonelelo zayo ezisebenzayo kunye nokungalunganga. Ngokomzekelo, iiplagi zebhulorho ezenziwe ngezinto ezidibeneyo zihlala zisetyenziselwa izicelo zoxinzelelo oluphezulu kuba ziyakwazi ukumelana noxinzelelo lwe-18,000-20,000 psi (124-137 MPa). Kwelinye icala, ukusetyenziswa kwabo ngokusisigxina kuthanda ukuboleka ukutyibilika ngokuhamba kwexesha ngenxa yokungabikho konxibelelwano phakathi kwezixhobo ezihlanganisiweyo kunye nezinto ezingaphakathi kumthombo. Iiplagi zebhulorho zenziwe ngaphandleJula i-ayiniokanye enye isinyithi inokuba ilungele ixesha elide okanye izicelo ezisisigxina, nangona kunjalo, azihambelani kakuhle kwiimeko zoxinzelelo oluphezulu.

Iiplagi zebhulorho azifakwa nje kwindawo yomthombo kwaye zishiywe ukuze zivale isiphelo, nangona kunjalo. Enyanisweni, ukubeka iplagi yebhulorho ngaphakathi kumngxuma womthombo ukuze kumiswe ngokusisigxina okanye okwethutyana ukuhamba kwe-oyile okanye irhasi yinkqubo enzima ekufuneka yenziwe ngobuchule nangobuchule. Kufuneka yenziwe ngelixa kusetyenziswa isixhobo seplagi yebhulorho esenzelwe ngokukodwa ukubeka iiplagi zebhulorho ngendlela esebenzayo.

Isixhobo esetyenziselwa ukubeka iplagi idla ngokuba mandrel tapered kunye threaded ukuba iphoswe embindini iplagi ibhulorho kwaye unemikhono ucinezelo ibekwe ngokulandelelana omnye komnye ukuze njengoko isixhobo ibamba iplagi, imikhono compress ngeenxa iplagi kwaye isixhobo sijikelezisa iplagi ezantsi kumngxuma wequla. Xa iplagi yebhulorho ikwinqanaba elifunwayo, isixhobo siyakhutshwa kwiziko le-axial yeplagi, kwaye singakhange sifundwe kwi-cylinder. Isixhobo siyasuswa kumthombo kunye neplagi ishiywe endaweni, njengoko imikhono iyancipha xa isixhobo singasenaso iplagi.
