随着石油工业的发展,水平井、侧钻水平井、分支水平井、大位移井、超短半径径向水平井等特殊工艺井技术已经成为降低油气开发成本、充分挖掘油田生产能力,提高油气采收率的有效技术手段.其中胜利油田孤岛地区多为超短半径径向水平井,目的为调整老区薄油层的开发水平,我队长期在孤岛地区施工,经过已完成井的钻探实践,总结出了本区域水平井的复杂情况防御钻井模式。 With the development of oil industry, special well technologies such as horizontal well, horizontal well, horizontal well, large displacement well and short radius radial well have become the key technologies to reduce oil and gas development costs, fully exploit oilfield production capacity and increase oil and gas Effective methods of recovery.Among them, Shengli Oilfield Gudao area mostly radial short-radius radial well, the purpose is to adjust the development of thin oil reservoirs in the old area, my team long-term construction in the island area, after completed well drilling practice, concluded Out of the complexity of horizontal wells in the region defense drilling mode.
