摘要
Abstract
High requirements of completion method and string design were proposed for high deviation and long perforation interval gravel packed well. Based on the comparison among all kinds of completion method, proper completion equipments and technology were chosen to optimize the gravel-pack completion design and operation procedure, to reduce the operation risk, and to ensure gravel packing successful. The limitation of one-trip multi-zone gravel-pack completion and the risk of operation were fully considered in a long perforation interval with high deviation in Bohai Oilfield. One-trip gravel pack completion with external casing packer was applied in this well, which satisfied the high requirements of multi-zone gravel packing and the efficiency of interval isolation. This well was successful and reduced the time for stack gravel-packing, which supply a good reference for other gravel pack completion under similar condition.关键词
