摘要
桩斜146井是胜利油田在滩海地区布置的一口较大位移的定向井,其钻探目的是为了解桩斜146断鼻上第三系含油气情况。该井设计井深2626m,水平位移1833m,垂深1700m,较大的井底位移给钻井工程带来了许多潜在风险。文章在介绍该井软地层、大尺寸井眼、浅造斜点、高造斜率施工技术难点的基础上,详述了在造斜段、稳斜段的施工过程及采取的有效技术措施,浅谈了作者对施工该类井的认识与建议。
Well ZX146 is an extended reach well on shore area of Shengli oilfield,which is used to exploit ZX146 structure.The well depth is 2626m,and horizontal displacement is 1833m which vertical depth is 1700m,so the large displacement brings some potential drilling risks.On the base of optimized drilling parameters and controlling well path,the target was drilled through and completed well successfully.This provided experiences for similar drilling of extended reach wells in the future.
