摘要:
为了得到置换法关井期间压井液下落速度计算方法，基于气液两相流理论，借助FLUENT和OLGA软件模拟了压井液下落过程，利用段塞流和Turner液滴下降理论，建立了置换法压井液在井筒中的下落速度模型。研究结果表明：置换法关井期间，压井液下落主要以段塞流或者环状流形式存在；与OLGA软件分析结果对比得出，压井液下落的初始峰值速度跟液滴模型相近，平均速度跟段塞流模型相近，建议置换法压井设计使用段塞流模型；关井套管压力越大，则压井时间越长；关井套管压力越大，且地层破裂压力越大，则压井次数越少，压井时间也较长；压井液密度越大，则压井时间越短，最终的套管压力就越小。
Abstract:
To obtain the calculation method of falling velocity for the killing fluid during the shutin process with the displacement method for killing, the falling process of the killing fluid was simulated by using the FLUENT software and OLGA software based on the theory of gasliquid twophase flow, and the model of falling velocity for the killing fluid in the shaft with the displacement method was established by using the slug flow and Turner droplet falling theories. The results showed that the falling of the killing fluid mainly existed as the form of slug flow or annular flow during the shutin process with the displacement method. Compared with the analysis results of OLGA software, the initial peak velocity of the killing fluid falling was similar to that of the droplet model, and the average velocity was similar to that of the slug flow model, so the slug flow model was suggested for the killing design with the displacement method. The larger the shutin casing pressure, the longer the killing time. The larger the shutin casing pressure and the formation fracture pressure, the smaller the killing number, and the longer the killing time. The larger the density of killing fluid, the shorter the killing time, and the smaller the final casing pressure.
