Abstract

Et helt elektrisk undervanns-ventiltre kan være koplet med en hydraulisk trykkenhet som er matet av elektriske - og styreledninger som er i navlestrengen fra overflaten. På denne måten behøver ikke hydrauliske ledninger separat å føres fra overflaten til treet. Alternativt kan hydraulisk trykk genereres ved et brønnverktøy ved å benytte kraft og styreledning som går fra treet til brønnutstyret. Som et annet alternativ kan brønnverktøyet være ført ved hjelp av elektrisk motor lokalisert nede i brønnhullet tilstøtende brønnhullsutstyret og drevet og styrt av ledninger som går fra treet til brønnstedet.A fully electric underwater valve tree may be coupled with a hydraulic pressure unit which is fed by electrical and control lines that are in the umbilical cord from the surface. In this way, hydraulic lines do not need to be routed separately from the surface to the tree. Alternatively, hydraulic pressure can be generated by a well tool using power and control line extending from the tree to the well equipment. As another alternative, the well tool may be guided by an electric motor located downhole adjacent the wellbore equipment and driven and controlled by wires extending from the tree to the well site.
