摘要
稠油热采由原来的蒸汽吞吐法发展为蒸汽驱法，使油层温度提高１００ ℃左右。由于温度的升高，一方面加速油水介质对抽油泵的腐蚀，造成活塞外表面镀镍层剥离；另一方面由于活塞与泵筒的环境温差加大，造成活塞与泵筒的间隙减小。剥离的镍层挤焊在过小的间隙之间是造成抽油泵被卡死的主要原因。
The stratum temperature of the heavy viscous crude in steam flowling operation is 100 ℃ higher than the steam stimulation which increases the causticity of the water and crude from the reservoir This is just the reason for the suck pump jamming in steam flooding due to the nickel plating stripped off from the piston and got stick within the narrow gap between the piston and inner cylinder surface
