Research on optimization method of casing perforating parameters in multi-cycle steam huff and puff horizontal well
To optimize the perforation parameters of casing in multi-cycle steam huff and puff horizontal wells while ensuring casing safety life,it is crucial to maximize reservoir productivity.Research on the influence of perforating parameters on both productivity and casing safety has led to the development of horizontal casing casing well skin factor calculation model and productivity prediction model.A method for selecting perforating parameters has been proposed,which operates within within the bounds of maximizing reservoir productivity and is informed by casing safety evaluation results.The perforation parameters designed by this method for a heary oil field in the Bohai Sea indicate that the production capacity has reached the allocation level while the casing is in a safe service condition,satisfying more than three cycles of steam huff and puff.This method can provide a basis for the optimization of casing perforation parameters in multi-cycle steam huff and puff horizontal wells.
