在油气井生产过程中,油井过早出现水气突破已成为制约水平井高效开发的技术难题。目前主要依靠流入控制设备、滑套找水堵水等技术来控制,但流入控制设备在长期开采后效果会变差,滑套技术依靠打开和关闭滑套对产层进行控制,效果不甚理想。贝克休斯公司研制Multi Node全电动智能井系统,主要由地上控制单元及地下主动式流量控制装置构
In the production process of oil and gas wells, premature water and gas breakthrough in oil wells has become a technical problem restricting the efficient development of horizontal wells. Currently mainly rely on inflow control equipment, sliding sleeve to find water to plug the water and other technologies to control, but inflow control equipment in the long-term mining effect will be worse, sliding sleeve technology to rely on to open and close the sleeve to control the production layer, the effect is less than ideal . Baker Hughes company developed MultiNode all-electric smart well system, mainly by the ground control unit and underground active flow control device
