isistimu ye-rotary steerable(RSS) iwuhlobo lokumbaubuchwephesheesetshenziswa kuukubhola okuqondisayo. Isebenzisa ukusetshenziswa kwemishini ekhethekile ye-downhole esikhundleni samathuluzi ajwayelekile aqondisayo afanaizinjini zodaka.Kuwushintsho olukhulu kubuchwepheshe bokubhola okuqondisayo kusukela ngeminyaka yawo-1990.
I-RSS drilling inezici zokungqubuzana okuphansi kanye nokumelana ne-torsional, izinga eliphezulu lokumba, izindleko eziphansi, isikhathi esifushane sokwakhiwa komthombo, umzila we-wellbore obushelelezi, ukulawula okulula nokwelulwa kobude besigaba esivundlile, njll., okubhekwa njengesiqondiso sokuthuthukiswa kokuqondisa kwesimanje. ubuchwepheshe bokubhola.
Isistimu yokuqondisa ejikelezayo ingahlukaniswa ngezinhlobo ezimbili zamasistimu ngokuya ngemodi yawo eyisiqondiso: Push the Bit futhi Khomba Ibhithi.
Ngaphezulu kuka-40% weMithombo eqondisayo yomhlaba ibholwa kusetshenziswa amasistimu ajikelezayo, anenzuzo yokulawula isikhathi sangempela sendlela yokumba ama-downhole, okufana "nenguqulo ye-3D yenyoka" ukulungisa ithuluzi lokumba. Lokhu kuvumela uhambo olulodwa ngokwakheka okuhlosiwe endaweni "yezinhlangothi ezintathu" - ngisho nebhithi elingu-0.2 m ububanzi linganqanyulwa eceleni noma nge-diagonally ngokusebenzisa ichibi elizacile elingu-0.7 m ukuze kuzuzwe uhambo olude "lwezinhlangothi" lwamamitha angu-1,000 endaweni eyodwa. uhambo.
Ngenxa yezindleko eziphakeme zobuchwepheshe, inqubekelaphambili elinganiselwe yenziwe ekugcineni okuphansi kwemakethe yokumba eqondisayo. Nokho, isiqondiso esinembile sinenani elikhulu ukuze kwandiswe ukuxhashazwa kwemithombo kawoyela negesi.
