Abstract

A portable drilling simulation system includes a main control computer, a graphic processing computer, a choke console and a blowout preventer console. The main control computer, the graphic processing computer, the choke console and the blowout preventer console are interconnected by a network and serial ports. The blowout preventer console includes a blowout preventer control panel. On the left of the blowout preventer control panel is provided a blowout preventer control zone. On the upper right is provided a throttling manifold control zone. On the lower right is provided a high-pressure manifold control zone. The flow plug console includes a flow plug control panel. A main control program runs on the main control computer and a graphic processing program runs on the graphic computer. The regular blowout preventer console, the regular throttling manifold, the regular high-pressure manifold and the regular flow plug console are integrated into the portable drilling simulation system, thus the simulated operation of several apparatuses on the control panel is realized.
