在全党全民大办地质勘探事业的今天,钻探生产有了很大的跃进。57年全国平均台月效率为174公尺,而今年1~10月份平均都已超过270公尺,净增100公尺左右。若按岩石可钻性的情况来看,软岩层的钻进效率比硬岩层提高要快,六级以内使用硬合金钻进的地层主要是由于多种型式钻头的采用,效率有了成倍的增加,特别是煤田队,在保证满足地质耍求的前提下,配合电测井工作,采用了不取岩心的刮刀钻头钻进,提高了几十倍,并出现了9台月进3000公尺以
Today, with the great efforts of the entire party and the people in carrying out geological exploration, great progress has been made in drilling production. In 57 years, the national average monthly efficiency of Taiwan and Taiwan reached 174 meters, while the average of January and October this year exceeded 270 meters, a net increase of 100 meters. According to the rock drillability case, the drilling efficiency of soft rock is higher than that of hard rock. The strata using hard alloy drilling within 6 levels are mainly due to the adoption of multiple types of drill bit, with double the efficiency Increase, especially the coal field team, under the premise of ensuring that the geological requirements are met, cooperate with the electrical logging work, use the coreless scraper bit to drill, increase tens of times, and there are 9 months into 3000 meters To
