摘要:
针对流花16-2油田海底管道原油蜡沉积严重的问题,利用环道蜡沉积实验,研究了不同原油温度、流速、油流与管壁温度区间及长时间老化作用影响下的蜡沉积规律和蜡沉积物性质。实验结果表明,在溶解度、剪切剥离、老化等不同的机理和作用下,原油温度、流速、油流与管壁温度区间及长沉积时间老化作用等因素不同程度地影响了蜡沉积物质量、沉积速率、含蜡量和实际沉积蜡质量。尽管流花16-2原油为低凝、低黏、低含蜡原油,但其所在海域较低的水温仍可使管道发生严重的蜡沉积,因此建议在制定清蜡方案时考虑更短的清管周期,确保油田海底管道的安全运行
Abstract:
Aiming at the serious problem of wax deposition in LH16-2 oilfield subsea crude oil pipeline, this paper discussed the wax deposition laws and the properties of wax deposits under the influences of different crude oil temperature, flow rate, oil flow and temperature range of pipe wall, as well as the long deposition time and aging effect through loop wax deposition experiment. The experimental results show that caused by different mechanisms and effects such as dissolvability, shearing/peeling, and aging, the above factors affect the wax deposit mass, deposition rate, wax content and the actual wax deposit mass to various extents. Although crude oil in LH16-2 oilfield is of low gel point, low viscosity and low wax content, serious wax deposition still occurs in pipeline due to the low seawater temperature. Therefore, it is recommended to consider a shorter pigging cycle when developing the wax removal scheme to ensure the safe operation of subsea pipeline
