摘要
西部钻探克拉玛依钻井公司在克拉玛依油田九6、7区及克浅井区完成了26口水平井的施工。结合这些井的实际情况,针对地层软、上下部造斜率差异较大,油层实际垂深与设计存在误差,目的油层夹层多、软硬交错造成井眼不规则,水平段大角度上翘等特点,根据开发方案和甲方的要求,制定了相应的技术措施,应用效果良好,形成了一套比较成熟的技术方法,对今后的浅层水平井钻井施工具有一定的指导作用。
The Karamay drilling company of The XIBU Drilling Engineering Company had finished 26 horizontal wells in the Karamay Oilfield district 9 6--7 and shallow well district. With the actual situation in these wells, such as soft formation, large slope-building difference rate from top to bottom of the forma- tion, the reservoir depth error occurring in actual vertical depth from design, complex interlayer, irregular borehole by soft-hard inter-bedded formation and high well oblique angle etc. , the pa- per, according to development scheme and the requirements of first party, put forward the appropriate technical measures. Its appliance effect is good and a set of mature technical methods had been built. It would play an important role in the future con- struction of shallow horizontal well drilling.
