Oiri uye gasi Kugadzira Wellhead Equipment
Dual Solid Block Tree
Kune mbiri mbiri tubing tambo, iyo yakasimba block muti ndiyo inonyanya kushandiswa kumisikidzwa. Idzo sarudzo mbiri dzakaratidzwa ndidzo dzakajairika magadzirirwo. Mavharuvhu anodzora kuyerera kubva munzvimbo yakadzika, tambo refu, ndiwo mavharuvhu ezasi pamuti. Kunyange zvazvo pane zvimwe zvisiri izvo kune iyi gungano, kunze kwekunge muti wakanyatsoratidzwa zvinogona kufungidzirwa kuti nzvimbo yevharuvhu inoratidzira subsurface connections.
