摘要:
为减小管汇弯头所受的冲蚀磨损率，在考虑固液两相流模型、流体控制方程及冲蚀磨损计算模型基础上，建立高压弯头冲蚀磨损数值模型，以现场工况为依据，对压裂液的流动速度、压裂液黏度、质量流量以及颗粒直径进行控制调整，研究高压弯头的冲蚀因素，得出各因素对弯头冲蚀磨损机理，总结各因素对弯头冲蚀磨损规律。结果表明：为减小冲蚀磨损率，提高高压弯头使用寿命，应减小施工压裂液的质量流量、选用直径较小的颗粒、压裂液黏度应为0.014 Pa·s左右；针对高压弯头提出弯径比为2～3、适当增加弯头的壁厚等改进措施。
Abstract:
In order to reduce the erosion wear rate of manifold elbow,based on the solidliquid twophase flow model,fluid control equations and erosion wear calculation model,the erosion wear numerical model of highpressure elbow was established.Based on the field conditions,the flow velocity,fracturing fluid viscosity,mass flow rate and solid particle diameter of the fracturing fluid were controlled and adjusted.After that,by studying the erosion factors of the highpressure elbow,the erosion wear mechanism and law of each factor to the elbow were obtained.The results showed that in order to reduce the erosion wear rate and improve the service life of highpressure elbow,it was suggested to reduce the mass flow rate of constructing fracturing fluid,select the solid particles with smaller diameter and the fracturing fluid viscosity of about 0.014 Pa·s.In addition,the improvement measures such as controlling the bending diameter ratio between 2~3 and appropriately increasing the wall thickness of elbow were put forward for the high pressure elbow.
