发明名称 WIRELESS DOWNHOLE WELL INTERVAL INFLOW AND INJECTION CONTROL
摘要 Apparatus and methods of electrically controlling downhole well interval inflow and/or injection. The downhole controllable well section (71) comprises a communications and controle modul e (80), a sensor (82), an electrically controllable valve (84), and an induction choke (90). The electrically controllable valve (84) is adpated to regulate flow between an exterior of the tubing (40) and an interior (104) of the tubing. Power and signal transmission between surface and downhole is carried out via the tubing (40) and/or the casing (30). When there are multiple downhole controllable well sections (72-75), flow inhibitors (61-65) separate the well sections.
