摘　　要：应用砂粒在直井和水平井中的运动规律及水平井产能计算理论,以新疆油田百重7克上组油层为例,计算水平井各种井身结构的冲砂参数。结果表明,如用清水冲砂,即使选择最优冲砂方式流体漏失仍非常严重,建议选择密度相对低的泡沫冲砂,并通过计算对泡沫冲砂参数进行了优选。Taking Keup reservoir in Baizong 7 block of Xinjiang Oilfield as an example,sand cleaning parameters of various horizontal wells are calculated by using the moving law of sand grains in vertical and horizontal wells and the productivity principle of horizontal well.The result shows that,even with the optimum way,fluid leakage is serious if conducting sand cleaning with water;we suggest sand cleaning with foam of relatively low density,and foam sand-cleaning parameters are optimized through calculation.
