摘 要：当前渤海油田钻完井作业主要采取钻井船和钻修机两种形式，其中钻井船设施齐备，但日费高昂；钻修机日费低，但设备参差不齐。在国际油价持续低迷的情况下，具有高性价比的钻修机模式被越来越多的涉及和采用。鉴于钻修机设施杂乱、配套不齐，无法满足作业需求的现状，需进行针对性改造。在此背景下，文章对渤海某平台的关键设备进行整改升级，使之达到钻完井作业能力标准和作业安全标准，最终顺利开钻，最终实现降本增效的目的，对后续类似作业有借鉴意义。

Abstract： At present， the drilling and completion operations in Bohai Oilfield mainly adopt two forms： drilling ship and drilling machine， in which the rig facilities are complete， but the daily cost is high； the daily cost of drilling and repairing machine is low， but the equipment is not uniform. Under the condition of the international oil price continuing to be depressed， the model of drilling machine with high performance and price ratio has been more and more involved and adopted. In view of the fact that the facilities of drilling machine are messy and the matching is not uniform， it is unable to meet the present situation of operation demand， so it is necessary to carry on the pertinence transformation. In this context， this paper carries on the rectification and upgrading to a certain platform in the Bohai Sea， so that it can reach the standard of drilling and completion operation ability and the operation safety standard， finally start drilling smoothly， and realize the purpose of reducing the cost and increasing efficiency. It can be used for reference to follow up similar work.

1 背景

依据机具作业能力，渤海现有钻修机可分为二大类，一类为“井架式钻修机”模式，一类为“纯钻修机”模式[1-2]。井架式钻修机配备可完成钻完井作业，包含钻机井架、钻机等设备BOP及高压管匯等关键设备，但甲板场地、泥浆泵、循环系统，动力系统、海水供给等均需要支持平台提供；纯钻修机的设备配置主要针对修井等作业，因此井架空间、提升能力、井控设备等均达不到钻完井作业要求，渤海某油田C平台就是其中一个。因此，为实现钻完井作业目的，就必须对钻修机设备进行改造升级，以满足钻完井顺利作业的要求。

2 目标改造平台现状

某油田C平台钻完井作业是在外挂槽口实施，前期作业由某钻井支持船提供作业支持。由于国际油价持续低迷，为响应公司降本增效战略，决定采用修井机作为作业机具，同时为提升其作业能力，C平台进行改造，增加并完善相应的钻完井设备。……
