Izixhobo zokuGqiba ze-BHA
Isiqinisi sokubhola sisixhobo esisetyenziswa kwi-downhole assembly (BHA) yomtya wokubhola. Sizinzisa ngoomatshini i-BHA kumngxuma ukuze kuthintelwe ukuphambuka okungacwangciswanga, ukungcangcazela, nokuqinisekisa umgangatho womngxuma ogqojozwayo.
Yenziwe ngomzimba osicaba ongenanto kunye neebhleyidi ezizinzisayo, zombini zenziwe ngentsimbi enamandla kakhulu. Iibhleyidi zinokuba zithe tye okanye zijikeleze, kwaye ziqinile ukuze zingagugi.
Iindidi ezahlukeneyo zeziqinisi zokubhola ziyasetyenziswa kwicandelo leoyile namhlanje. Nangona iziqinisi ezidityanisiweyo (ezenziwe ngomatshini omnye wentsimbi) ziqhelekile, ezinye iintlobo zingasetyenziswa, ezinje:
Isiqinisi semikhono esinokutshintshwa, apho iiblade zibekwe kwisingxobo, esiza kuthi emva koko sifakwe ngezikrufu emzimbeni. Olu hlobo lunokuba lolwexabiso eliphantsi xa kungekho zixhobo zokulungisa zifumanekayo kufutshane nendawo egrunjwayo kwaye kufuneka kusetyenziswe uthutho lomoya.
Isiqinisi seeblade ezidityanisiweyo, apho iiblade zidityaniswe emzimbeni. Olu hlobo alusoloko lucetyiswa kwimithombo yeoyile ngenxa yemingcipheko yokulahlekelwa ziiblade, kodwa lusetyenziswa rhoqo xa kugrunjwa imigodi yamanzi okanye kwiindawo zeoyile ezingabizi kakhulu.
Ngokwesiqhelo kufakwa iziqinisi ezi-2 ukuya kwezi-3 kwi-BHA, kuquka enye engentla kancinci kwe-drill bit (near-bit stabilizer) kunye nenye okanye ezimbini phakathi kwee-drill collars (string stabilizers)
