SLIM HOLE DRILLING TECHNIQUE FOR CASING WINDOW SIDETRACKING
套管定向开窗侧钻小眼井钻井技术
The paper presents the mechanical and hydraulic rock breaking capacity of bits, small-size bit status, slim hole drilling techniques and tools conditions, and chip hold down effect, which are the reasons made lower penetration rate, and gives the technical measurements for improving slim hole penetration rate, such as small-size bit optimum selection, drilling method and new type drilling tools, and so on.
从钻头的机械和水力破岩能量、小尺寸钻头状况、小眼井钻井工艺及工具状况及压持效应等方面分析了造成小眼井钻井机械钻速低的原因,并从小尺寸钻头优选、钻井方式及新型钻井工具等方面给出了提高小眼井钻井速度的技术措施。 |
