一、钻井设备 随着较易开采的浅油气层储量的逐年消耗,石油钻探和开发不断向深部地层发展。在美国,1959年最深探井为7724米,平均钻井深度为1282米,1974年,最深探井达到9583米,平均钻井深度为1436米。1938年,美国打成了第一口4573米深的井。1959 First, the drilling equipment With the exploitation of shallow gas reservoirs year by year depletion, oil drilling and development continue to the deep stratigraphic development. In the United States, the deepest exploratory wells in 1959 were 7724 meters with an average drilling depth of 1282 meters. In 1974, the deepest exploration wells reached 9583 meters with an average drilling depth of 1436 meters. In 1938, the United States made its first well of 4573 meters deep. 1959
