1.1 本国际标准规定了钢管(套管、油管和短节)、接箍毛坯、接箍材料和附件材料的技术交货条件,并规定了三个产品规格等级(PSL-1、PSL-2、PSL-3)的要求。 。 PSL-1 的要求是本国际标准的基础。除 H-40、L-80 9Cr 和 C110 之外的所有钢种,定义 PSL-2 和 PSL-3 不同级别标准技术要求的要求包含在附录 H ...
a从油井的结构特征可知,油管和套管之间的距离比较接近,在考虑井下系统的发射信号时,不宜采用电压幅值较大的信号。 May know from the oil well structure characteristic, between the drill tubing and the drive pipe distance is quite close, when consideration mine shaft system transmitting message, not suitab...
a信号的传输是通过生产油井的油管和套管作为传输路径实现“无线传输”的,即不需要传统的数据传输信道—电缆、光纤等。图1为无线传输系统中信号路径示意图。 The signal transmission is through the recovery well drill tubing and the drive pipe took transmission route realization “wireless transmission”, namely ...
间歇抽油井5) batch control 间歇控制 1. The status quo and developing tendency of batch control hardware and software, on-line recipe management and production scheduling are discussed in particular. 本文从控制角度分析间歇过程的特征,并介绍间歇控制装置和控制软件的现状和发展趋势,特别是配方管理和生产...
