沙特SHYB区块目前所钻生产井大多数为多分支水平井,打好多分支水平井的关键因素之一是斜向器的优选。可回收式液压斜向器具有技术先进、安全性高、综合效益好等特点,施工过程中,具有前期准备工作量小,入井、坐封和开窗可以一趟钻完成,取回方便等优点,因此,该斜向器在SHYB区块得到了广泛应用。本文以该斜向器在SHYB594井的实际应用情况为例,论述了有关技术问题及要求,为同类井的施工提供参考。
At present, most production wells drilled in the SHYB block in Saudi Arabia are multi-lateral horizontal wells. One of the key factors for laying multi-lateral horizontal wells is the preference of the inclined planes. Recyclable hydraulic oblique device has the advantages of advanced technology, high safety and good overall efficiency. During the construction process, it has the advantages of small preparatory workload, well entry, setting and opening, complete drilling and retrieval, and convenient retrieval Therefore, the slant is widely used in the SHYB block. In this paper, the actual application of the inclined shaft in SHYB594 well is taken as an example to discuss the technical problems and requirements, and to provide reference for the construction of similar wells.
