胜利油田第一口绕锥水平井钻井技术

The First Surrounding Water Cone Horizontal Well Drilling Technique in Shengli Oilfield

摘要:

胜利油田永3断块是典型的复杂小断块油藏，为进一步对该类型油藏进行挖潜，在仔细分析剩余油富集模式的基础上，决定在合适位置部署绕锥水平井。在分析了永3断块储层特点的基础上，介绍了永3断块第一口绕锥水平井——永3平6井的基本设计及施工情况，阐述了绕锥水平井钻井的技术难点和采取的技术措施。该井的成功实施及顺利投产，证明了绕锥水平井适合胜利油田东部老油区剩余油的进一步挖潜，具有推广价值。

Abstract:

Y3 fault-block of Shengli oilfield is a typical small complex fault-block oil reservoir. In order to further explore the potential of this kind of reservoir, surrounding water cone horizontal well is used on the basis of recognizing the enrichment pattern of remained oil distribution. This paper analyzes the characteristic of the reservoir of Y3 fault-block, introduces the design and drilling construction of the first surrounding water cone horizontal well-Y3P6 well and illustrates some technical difficulties and countermeasures in this well construction. By the successful operation of this well, it is proved that the surrounding water cone horizontal well is suitable for the potential tapping of remaining oil in old oil region of Shengli oilfield with popularization value.
