Research on Switching Performance of Sliding Sleeve

Two main technical indicators for evaluating the performance of the sliding sleeve switch in well completion production are put forward, namely, the maximum collet spike force, jar switching times. The theoretical solution model for the maximum collet spike force and sliding shifting force of the sliding sleeve collet fingers was established and verified by the ANSYS statics simulation analysis of the collet fingers. The consistency indicates the correctness of the theoretical solution model and the adaptability to engineering applications. A theoretical solution model for sliding sleeve jar switch times was established, and the sliding sleeve shock switch test equipment was designed and manufactured based on the model, and the applicability of the established theoretical model was verified by combining the test results of the sliding sleeve jar switch.
