Research and analysis of forward and reverse circulation gravel deposition of multi-layer sand control pipe strings
To address the issue of gravel flow deposition in the string tool of CNOOC's mul-ti-layer filling/fracturing construction,we conducted gravel deposition experiments and flow simulation research on the sand control tool.In this paper,we utilized the forward and re-verse circulation gravel deposition device of the sand control tool to simulate the flow of the sand mixing solution within the filling tool under various dip angles and sand ratios.Moni-tored the sedimentation form and deposition amount of the complex structure of the sand mixing solution within the sand control tool.By analyzing these patterns,optimized the structure of the pipe string to provide insights into resolving the challenge of lifting the pipe string caused by deposition within the pipe.
