5000 m井架式修井机在金县1-1油田的应用

摘要

Adapt to the flexibility and timely adjustmentof the offshore oil field, when selecting the drilling and workover equipment, JinXian 1-1 oil field in BoHai bay creativelyallocated 315 tons hoisting system workover which has 5000 meters drilling depth ability, but mud circulating system and other matching equipments follows normal 180 tons workover configuration. 5000 meters derrick workover rig can drill adjustment well on later production stage with cooperation of the multiple function living and supporting platform. This design can reduce initial drilling and completion investment, increase benefit giving consideration to workover and adjustment operation of oil fieldsimultaneously.%为了适应海上油田后期灵活、适时调整开发，在钻修井机具选型方面，渤海金县1-1油田修井机创造性地配备了315t提升系统（具备5000 m钻完井作业能力），循环系统和其它配套设备仍按照180t常规修井机配置。5000 m井架式修井机在多功能生活支持平台的配合下，可实现油田后期钻完井作业。该设计能在兼顾油田修井、调整井作业的同时，有效降低油气田开发初期钻完井作业投资，提高油气田开发效益。
