摘要
为了解决复杂地层钻探施工难题,文章以海口江东新区地热钻探工程为例,深入分析复杂地层特性,采用XSL5/280履带式全液压水井钻机进行空气潜孔锤钻进施工,并依据定向钻探勘察数据进行综合地质评价。最后,采用勘探取芯法开展钻探勘察成果分析,发现综合测井各方面参数均符合工况要求。
In order to solve the problems of drilling construction in complex strata,this paper takes the geothermal drilling engineering in Jiangdong New Area of Haikou as an example to deeply analyze the characteristics of complex strata.The XSL5/280 crawler full hydraulic water well drilling rig is used for air down-the-hole hammer drilling construction,and the comprehensive geological evaluation is carried out according to the directional drilling survey data.Finally,the exploration coring method is used to analyze the drilling survey results,and it is found that all parameters in the integrated logging meet the requirements of the working conditions.
