Mutsetse diki-diameter hydraulic mutsetse unoshandiswa kushandisa downhole kupedzisa midziyo yakadai seyepamusoro inodzorwa pasi pepamusoro pekuchengetedza vharafu (SCSSV).Mazhinji masisitimu anoshandiswa neanodzora mutsara anoshanda pane inotadza-yakachengeteka hwaro.Mune iyi modhi, mutsara wekutonga unoramba uchimanikidzwa nguva dzese.Chero kuvuza kana kutadza kunokonzeresa kurasikirwa kwekudzora mutsara kudzvanywa, kuita kuvhara vharafu yekuchengetedza uye kupa tsime rakachengeteka.
Yepamusoro-inodzorwa pasi pesevhavhavha yekuchengetedza (SCSSV)
A downhole kuchengetedza vharafu iyo inoshandiswa kubva pamusoro pezvivakwa kuburikidza netambo yekudzora yakasungirirwa kune yekunze pamusoro peiyo tubhing yekugadzira.Mhando mbiri dzekutanga dzeSCSV dzakajairika: wireline inogona kudzoserwa, iyo iyo huru yekudzivirira-vhavhavha inogona kumhanya nekudzoserwa pane inotsvedza, uye tubing inogona kudzoserwa, umo iyo yese yekuchengetedza-vhavhavha inoiswa netambo yechubhu.Iyo yekudzora sisitimu inoshanda mukutadza-yakachengeteka modhi, ine hydraulic control pressure inoshandiswa kubata yakavhurika bhora kana flapper musangano unozovhara kana kudzora kudzvinyirira kwarasika.
