Influence of power characteristics of screw bottom-hole engines on drilling speed per run
Power characteristics of low-speed and high-speed screw bottom-hole engines pay influence on drilling speed per run when drilling of oil and gas wells. Influence of human factor when operating of screw bottom-hole engines makes it difficult to keep the fixed differential pressure drop. Upgrading and implementation of automated systems, namely, bit feed control device on the basis of pressure control in the manifold line and automatic change of drilling tool feed rate, provide possibility of controlling drilling speed per run.
