石油钻井工程中消耗大量金属套管。例如,据统计,60年代苏联生产的无缝钢管大约70％左右供给了石油工业,而其中大部分是作为套管使用。我国一口3000米左右的井平均消耗套管金属约在150～250吨左右。为了实现华主席、党中央提出的在我国创建十来个大庆的伟大目标,我国石油工业将进入一个新的迅猛发展时期。今后的钻井进尺将大幅度增长。深井所占比例和钻井深度将不断增加。因此,研究如何降低一口井的套管金属消耗量具有很大意义。
Oil drilling projects consume a large amount of metal casing. For example, it is estimated that about 70% of the seamless steel tubes produced by the Soviet Union in the 1960s were supplied to the oil industry, most of which were used as casing. The average consumption of casing metal in a well of about 3,000 meters in our country is about 150-250 tons. In order to realize the great goal put forward by Chairman Hua and the Party Central Committee in establishing a dozen or so Daqing in our country, China’s petroleum industry will enter a period of rapid development. The future drilling footage will be substantially increased. The proportion of deep wells and drilling depth will continue to increase. Therefore, it is of great significance to study how to reduce the casing metal consumption in a well.
