A downhole stabilizer chidimbu chemudziyo wepasi chinoshandiswa mugomba rezasi (BHA) retambo yekuboora. Inodzikamisa iyo BHA muchibhorani kuitira kudzivirira kutsaukira kusingafungidzirwe, kuzununguka, uye kuve nechokwadi chemhando yegomba riri kucherwa. Inoumbwa neine gomo cylindrical body uye mashizha anodzikamisa, ese akagadzirwa nesimbi yakasimba-yakasimba. Iwo mablades anogona kunge akatwasuka kana akatenderedzwa, uye akaomeswa nekusapfeka.
Iko kune kunyanya matatu marudzi ekuchera zvigadziro anoshandiswa munzvimbo yemafuta nhasi.
1. Integral stabilizer, iyo yakanyatsogadzirwa kubva kune imwe chidimbu chesimbi. Rudzi urwu runowanzove rwakajairwa uye runoshandiswa zvakanyanya.
2. Replaceable sleeve stabilizer, apo mashizha ari pane sleeve, iyo inobva yaputirwa pamuviri. Rudzi urwu runogona kuve nehupfumi kana pasina zvivakwa zvekugadzirisa zviripo padyo netsime riri kucherwa.
3. Welded blades stabilizer, uko mablades anosungirirwa pamuviri. Rudzi urwu kazhinji haruna kurairwa pamatsime emafuta nekuda kwenjodzi dzekurasika kwemashizha, asi rinogara richishandiswa pakuchera matsime emvura kana paminda yemafuta inodhura.
Kazhinji 2 kusvika ku3 stabilizers inoiswa muBHA, kusanganisira imwe chete pamusoro pechibooreso (near-bit stabilizer) uye imwe kana maviri pakati pemakora ekuboorera (tambo stabilizers).
Nepo mabasa ekuchera angave akaoma uye ane ngozi, kushandiswa kwechigadziro chekudzikisa zvakanyanya kunoderedza njodzi yekuchera nyaya, kuve nechokwadi chekuti nzira yekuchera inofamba zvakanaka uye zvakanaka.
Simba rinogara richiomerera pakuita basa repamusoro-soro uye zvigadzirwa zvemhando yepamusoro, kana iwe uchifarira mafuta uye gasi downhole maturusi, ndapota usazeza kubata nesu.
