摘　　要：塔里木油田HLHT区块地质情况复杂,具有储层埋藏深、非均质性强和岩层可钻性差等特点,导致该区块开采难度较大,钻井开发周期长。对此,通过分析塔里木油田HLHT区块的地质特征,结合静态资料及油田开发数据资料,讨论了该区块钻井技术难点,从钻头优选和水力参数优化等方面出发,提出了提高该区块开发效率的多种方法,并讨论了各自的优势与局限性,为解决该地区井下复杂情况及提高钻井效率打下基础。The geological situation of HLHT block in Tarim Oilfield is complicated. The characteristics of deep buried reservoir,strong heterogeneity and poor drillability of rocks lead to the difficulty of exploitation and long drilling and development cycle in this block. Based on the analysis of the geological characteristics of HLHT block in Tarim Oilfield,combined with the static data and oilfield development data,this paper discusses the drilling technical difficulties in this block. Starting from the aspects of bit optimization and hydraulic parameter optimization,various methods to improve the development efficiency of this block are proposed,and the advantages and limitations of each are discussed. It lays a foundation for solving the complicated underground situation and improving drilling efficiency in this area.
