沙漠油田钻井平台防风治沙试验模拟

The Simulation of Shifting Sand Prevention for Oil Drilling Flat in Desert Region

该文针对沙漠油田开发中钻井平台所遇到的风沙危害状况，对４种透风系数、３类（１２种）机械沙障进行不同条件下的实验模拟．从中可以看出：①机械沙障是一种有效的防风固沙措施，可广泛地用于沙漠地区油田开发中；②在石油钻井平台周围，以防风为主的条件下可以使用Ａ类沙障，如既考虑防风而又防止积沙时（在石油钻井平台周围，考虑工人施工时防风效果，而又防止积沙埋没石油钻井平台），可根据实际情况采用Ｂ类或Ｃ类沙障；③所选沙障的具体透风系数可根据防护对象的实际情况。

Based on the state of shifting sand and its harzards to oil drilling in the desert area,12(3×4)types of wind fences have been tested in the wind tunnel.The simulation shows that:(1)wind fence is one of the effective measure which would be used in oil drilling flat in desert region for wind prevention and shifting sand controling;(2)If only for wind prevention around the flat,type A would be used,type B or type C can also be used in wind prevention and meanwhile avoiding shifting sand sediment near the flat;(3)The fence's ventilation coefficient should be determined by local weather condition.
