Muva nje, i-rotary steerable PDC bit kanye ne-downhole motor eyenziwe ngokuzimela yinkampani yethu iye yafaniswa ngempumelelo nemishini yokuhambisa engenayo ephuma emthambekeni wesithathu wokuvula nendawo evundlile yomthombo we-Wei202H2-10 (2936-4237m, ukwakheka kweLongmaxi) kuboshwe iqembu 50022 we-Great Wall Drilling Company. Ifeze ukusebenza obekulindelwe futhi yanconywa ngazwilinye yizinkampani zokubhola kanye nezinkampani eziqondisa izinkonzo.

Imoto ye-PDC eguquguqukayo eguquguqukayo ne-downhole motor ibhola phansi kabili esigabeni esikhulayo, ngemifanekiso eqoqayo yamamitha ayi-1,301, lapho amamitha ayi-700 abholwa ngokuvundlile. Isikhathi sonke sokubhola singamahora ayi-117, isikhathi sokusebenzisa isikulufa singamahora angama-229, kanti isilinganiso sokungena singamamitha ayi-11.12 ngehora. Njengomphumela wokushintsha indlela ejwayelekile yokukhipha kancane ngenkathi kubhola okuqondisayo, ibhithi esetshenzisiwe ingama-95% njengebhithi entsha yokuqala.

I-rotary PDC bit iyinhlobo entsha entsha eyenziwe yinkampani yethu yokuguqula imishini yokujikeleza engaguquguquki kanye ne-rotary steerable downhole motor ukuhlangabezana nezidingo zentuthuko yegesi ye-shale kanye nokwakheka okukhethekile. Lolu hlobo lwe-bit luhlanganisa nelungelo lethu lokuzimela elizimele lobuchwepheshe obulula bokulawula, ukuvimbela ubuchwepheshe bokunamathela kancane, ubuchwepheshe bokuthuthukisa i-Gauge futhi isebenzisa ama-PDC Cutters asebenza kahle. Inezici zokulawula okuhle kwe-azimuth, isivinini esikhulu sokujikeleza, akukho ngozi, ukusebenza okuzinzile nokuphila isikhathi eside ngenkathi kubhola.

Ukuthuthuka okuphumelelayo nokusetshenziswa kwe-PDC eguquguqukayo ye-bit kanye ne-downhole motor kungenye impumelelo enkulu yenkampani yethu ocwaningweni oluzimele nasekuthuthukiseni amathuluzi wokubhola. Ukukhuthazwa nokufakwa kwayo kungathatha indawo yemikhiqizo engenisiwe, kunciphise kakhulu izindleko zokumba, futhi ithemba layo lemakethe libanzi.
