侧钻新技术在锦45-24-18C井的应用

APPLICATION OF THE NEW SIDETRACKING TECHNIQUES IN WELL JING 45-24-18C

辽河油田自1992年实施侧钻井以来到目前约已完井1600余口,但如何提高侧钻井质量及降低侧钻井成本,一直是困扰油田侧钻井进一步发展的问题。经过多年研究与试验,在锦45-24-18C井上成功地实施了套管开窗一体化、扩孔与随钻扩孔、完井液压套管扶正器、粘砂套管新工艺与技术,为今后侧钻井技术的进一步完善发展提供了基础,有一定的推广价值。

It has been drilled more than 1600 sidetracking well in Liaohe oilfield since 1992. But the problem that how to improve the side-tracked hole quality and lower the costs of sidetracking well has affected the further development of sidetracking well. By research and testing in many years, the milled window in casing, reaming and reaming while drilling, completion hydraulic centralizer, glues sand casing etc. new technology are used successfully in well Jing 45-24-18C. The new sidetracking techniques have definite expansion value, and provide the foundation for further perfecting and developing of sidetracking well technique in future.
