立井井筒施工中掘进和支护两大作业之施工方式,一般分为单行作业与平行作业两大类。多年来创立井快速施工纪录的大多是采用平行作业方式,其成井速度最高达401.3米/月(1969年苏联)。我国1951～1958年6月,立井采用平行作业施工的月成井速度一直保持着国内最高纪录,1958年7月以后,便让位于单行作业。我国单行作业最高纪录为174.82米/月,平行作业为134.3米/月(见表1)。作业方式要根据工艺水平和具体装备、技术条件进行选择,才能提高成井速度及其它技术经济指标,现拟就其中有关方面谈一些探讨意见。
Vertical wellbore construction in tunneling and supporting two major construction methods of operation, generally divided into single-line operation and parallel operation of two categories. For many years, most of the quick construction records of wells were created by means of parallel operation, and their formation rate reached as high as 401.3 m / month (1969 Soviet Union). China’s 1951 ~ 1958 June, vertical wells using parallel operation of the monthly rate of well logging has maintained the highest domestic record, after July 1958, they give way to a single job. China’s highest single-job record of 174.82 m / month, parallel operation of 134.3 m / month (see Table 1). Operating methods should be based on the level of technology and specific equipment, technical conditions to choose, in order to improve the speed of wells and other technical and economic indicators, it is proposed to discuss some of the parties concerned.
