消泡技术是提高泡沫钻井效率的关键技术。为了提高机械式泡沫破碎器在泡沫钻井中的性能，研究了一种新型的双缝气动式泡沫破碎器。利用ANSYS Fluent计算流体力学软件对泡沫破碎器内部的速度和压力分布进行了数值模拟，并根据模拟结果确定了两环形狭缝的最佳间距。同时，对该泡沫破碎器的实际性能进行了一系列的实验测试。结果表明，影响泡沫破碎器效率的因素很多，包括泡沫气液比、基础液粘度、供气方式等。较高的泡沫气液比和空气供应压力可实现上级破泡性能。泡沫液相的粘度表现出完全相反的行为，这意味着泡沫破碎剂更有效地从较低粘度的液体中破坏泡沫。验证了该新型空气动力破泡器的实用性，并探讨了不同参数对破泡率的影响，为后续的破泡研究提供参考和指导。
Defoaming is a key technology for increasing the efficiency of foam drilling in petroleum engineering. To enhance the performance of a mechanical foam breaker in foam drilling, a novel aerodynamic foam breaker with two annular slits was investigated in this study. The computational fluid dynamics code of ANSYS Fluent was used to simulate the velocity and pressure distribution inside the foam breaker, and the optimum distance between the two annular slits was determined based on the simulation methods. Meanwhile, a series of experiments were conducted to test the actual performance of the foam breaker. The results demonstrate that various factors may affect the efficiency of the foam breaker, including the foam gas‐liquid ratio, basic liquid viscosity, and air supply method. A higher gas‐liquid ratio of the foam and air supply pressure result in a superior foam breaker performance. The viscosity of the foam liquid phase exhibits exactly the opposite behavior, meaning that the foam breaker more effectively destroys foam from a lower‐viscosity liquid. This study verifies the practicability of this novel aerodynamic foam breaker and discusses the effects of different parameters on the defoaming percentage, and this study can act as a reference and guidance for subsequent defoaming research.
