HIGH PRESSURE JET PERFORATION SYSTEM |
摘要 |
<p>A technique facilitates removal of excess sand during a jet perforating operation without requiring that the perforating string be pulled out of hole. A jet perforating tool is provided with at least one perforating nozzle for creating perforations in a well via high- pressure fluid. The jet perforating tool also comprises at least one wash nozzle oriented to direct fluid under pressure against a sand plug to break loose excess sand. A pair of seats and plug members may be used in the jet perforating tool to control the flow of pressurized fluid through the perforating jet nozzle and/or the wash nozzle.</p> |
