The frontal Flow Analogy Research on ACP Material in Horizontal Well Annular

摘要

At later stages of the horizontal well production, water output restricted development effectiveness. The technique of ACP can shut off the water in horizontal well whose well completion system was slotted screen pipe completion. The rheological equations of various flow patterns fluid were unified into one general equation. Based on the N-S equation, the relationship between the velocity and the pressure drop was found and handled non-dimensionally, the pressure drop and the velocity were solved according to the boundary condition and the numerical analysis. The software whose integrated development environment is VB was developed to calculate velocity and simulate flow. The results indicate the velocity in a narrow place is low and there exists the flow nuclear in the annulus. In order to improve quality of ACP material injection, the centralizer must be adopted more.
