AI Technical Summary
压井液的配制需实现基液与各类添加剂（如加重剂、堵漏剂、防膨剂等）的均匀混合，同时需避免配制过程中产生大量泡沫、原料团聚、混合不均以及泵体吸入涡旋等问题，否则会严重影响压井液的密度、粘度等核心性能，进而引发井壁坍塌、卡钻、井漏等井下复杂事故，威胁作业安全并延误施工进度
[0014]Compared to existing technologies, the advantages of this invention are that, by adopting the above-mentioned solution, the liquid curtain generating device, the feed distribution device, and the upward guiding device are sequentially arranged inside the tank, and an axial flow pump is installed at the bottom of the upward guiding device. This achieves forced axial circulation and multi-stage shear mixing of the kill fluid inside the tank, solving the problems of additive agglomeration, uneven mixing, and uneven density and viscosity distribution of the kill fluid caused by the limited stirring range and insufficient stirring intensity of traditional stirring devices. Furthermore, by setting a downward defoaming device on the outer periphery of the upward guiding device, continuous defoaming is achieved throughout the circulation process of the kill fluid, solving the problems of excessive foam generation and difficulty in elimination during the preparation process of traditional equipment, which leads to insufficient actual density of the kill fluid, unstable pump pressure, air lock, and misjudgment of the liquid level.
