Guide Shoe iri nyore uye ine hupfumi maitiro ekumhanyisa casing mutsime. Izvi zvakasungirirwa kuzasi kwecasing uye zvinopa buoyancy kune tambo yekasi painodzikiswa.

Iyi dhizaini ine tepi yemukati pazasi kuti ive nechokwadi chekupinda-kusanetsa kwemidziyo yekuchera kudzoka mutambo yecasing mushure mekudhirowa uye panguva yekuchera. Iyo mhuno yakatenderedzwa inotungamira casing kubva pamigero uye zvinovharira mumatsime sezvo casing inodzikiswa.

A yakavakirwa-mukati cheki vharuvhu inopa buoyancy kune casing tambo uye zvakare inodzivirira simende kuti isapinda zvakare mubhokisi mushure mekunge yabviswa. Zvese zvemukati zvikamu zvakazara PDC inodhirikirwa.

Iyo Inotungamira Shoe chishandiso chakakosha pakuvaka tsime, chakagadzirirwa kukwenenzvera nzira yekuisa casing. Dhizaini yayo inovimbisa kushoma kushomeka uye kunetseka panguva yekushanda. Iyo yakavakirwa-mukati cheki valve haingobatsiri chete mukuchengetedza buoyancy yetambo yekaseti asiwo inovimbisa kuvimbika kwebasa resimende nekudzivirira sement backflow. Uyezve, kuenderana kwayo nePDC drilling inoita kuti ive yakakodzera kumabasa ekuchera kwemazuva ano. Kuwanikwa kwayo muhukuru hwakasiyana-siyana, uye sarudzo yehukuru hwakakosha pakukumbira, inoita kuti ive chishandiso chinochinjika chinochinjika kune akasiyana siyana magororo saizi uye casing tambo.
