摘要: 为了解决渤海油田地面槽口不足和部分井低产低效的问题,开展了大量侧钻井工作,其中中短半径侧钻井是近年来研究的主要方向。长期以来海上油田由于受防砂管柱、电潜泵生产方式等因素限制,中短半径侧钻井技术处于应用空白。在分析海17H2井基本情况、刮管洗井难点、射孔难点等问题的基础上,通过设计优化、管柱通过
性数据模拟分析和地面试验、入井试验,最终成功实现渤海首口中短半径水平套管井射孔技术应用。为渤海油田的进一步发展提供了有力的技术支撑。

Abstract: With the development of Bohai Oilfield, there are a lot of low production wells, while the number of slots is insufficient. In order to make good use of these wells and slots, a large number of side tracking wells have been developed. In this respect, medium and short radius side tracking is the main research direction in recent years. This technology is widely used in land oilfields, but has not been used in offshore oilfield before. We analyse the basic situation of the 17H2 well and describe the difficulty of scraping and perforation. Through the design optimization and the passing performance simulation and test of the pipe column, the first application of perforation technology to shorttomedium radius horizontal casing well in Bohai is achieved. It provides a strong technical support for the further development of Bohai Oilfield.
