Building a High Efficient and Intelligent Digital Oilfield Water Injection System

Water injection exploration is a primary technology to ensure crude oil production. Especially during the mid to late term of oil field development, no water injection means no crude production. Therefore, oilfield companies set up large injection pump station and pipe network system to guarantee normal operation and increasing production. Simulation evaluation, optimized running management and automatic control of injection system construction schemas constitute the main research subject in building high efficient water injection system. A simulation optimization software of injection system was developed, Pump-Control-Pump (PCP) technical equipment and plunger pump frequency conversion equipment, which accomplished the automatic control and intelligent management of water injection system, are widely used in nationwide oilfields. This paper introduces the research results of dynamic simulation optimized software of injection pipe network, PCP system and plunger pump frequency conversion system.
