| 中文摘要:针对叶县盐田的地质条件，上部无岩心钻进，采用大钻压、低转速、高泵压、大泵量喷射钻井的快速钻进技术；下部取心钻进，采用小钻压、高转速、低泵压、小泵量的取心钻进技术。采用防塌淡水泥浆与饱和盐水泥浆分别治理取得了较好的技术效果。 |

| Abstract:With respect to the geological conditions in the salt field of Ye County, full-face drilling is per-formed in the upper section of the well using high speed jet drilling technology with high bit pressure, low rotaryspeed, high pumping pressure and high pumping rate, while in the lower section core drilling is carried on using core drilling technology with low bit pressure, high rotary speed, low pumping pressure and low pumping rate.Anti-cave fresh water mud and saturated salty water mud are employed , resulting better technical benefit. |
