Abstract

By using fluid dynamics calculation, we start a numerical simulation research on flow fields of cylindrical and conical nozzle in order to choose a better structure of cementing ground anchor, at the same time, we also do hydraulic cycle experiments on cylindrical nozzle with different bore diameter. According to the result: cylindrical nozzle has an obvious throttling effect so that cylindrical nozzle is the better choice for cementing ground anchor; the theoretical differential pressures of nozzles with different diameters are very close to experimental date; the flow coefficient of the nozzle doesn’t trend to a constant, when Reynolds number of the nozzle is 25000~35000, the nozzle has more flow coefficient; as the Reynolds number increases or decreases, the flow coefficient decreases and the damping of the flow increases. The result does a great contribution to the thermal recovery of heavy oil and pre-pressure cementing.
