在油田的油水井开发生产过程中,随着开发年限的增长,及生产井所处区域的地质因素,开发前期工艺水平和各种增产措施等因素的影响,都有可能造成卡钻事故,严重威胁着油田的正常生产,在处理事故的过程中,事故及井况的复杂性和多样性再加上修井工具性能指标的限制,使修井成本居高不下,修复难度较大。因此,在大井斜深井中如何提高施工措施的有效率,降低施工风险便成为我们研究的课题。
Oil and water wells in the oilfield development and production process, with the development of years of growth, and production wells in the region where the geological factors, the level of the development process and a variety of stimulation measures and other factors, are likely to cause a stuck pipe accident, serious Threatening the normal production of the oilfield. In the process of handling the accident, the complexities and diversities of the accident conditions and the well conditions coupled with the limitation of performance indicators of the workover tools make the workover cost high and the repair is difficult. Therefore, how to improve the efficiency of construction measures and reduce the construction risk has become the subject of our research.
