摘要： A single tractor unit is provided for pulling a tractor, in which the tractor itself drives a plurality of hydraulic motors which control a crane unit, a coiled tubing injection unit, and the pumps and motors associated with a liquid nitrogen system which is used for injecting gaseous hydrogen into a workover well with coiled tubing. In an alternative mode, the liquid nitrogen system is replaced with one or more nitrogen generators which gather nitrogen from the earth's atmosphere to be pumped through the coiled tubing into the well being treated. Alternatively, the gaseous nitrogen source is one or more tanks of compressed nitrogen gas.
摘要翻译：提供了一个拖拉机单元，用于牵引拖拉机，其中拖拉机本身驱动多个液压马达，其控制起重机单元，连续油管注入单元以及与用于喷射的液氮系统相关的泵和马达气态氢气进入带有连续油管的修井井。在替代模式中，液氮系统由一个或多个氮气发生器代替，氮气发生器从地球大气中收集氮气，以将其通过连续油管泵送到待处理的井中。或者，气态氮源是一个或多个压缩氮气罐。

摘要： A single tractor unit is provided for pulling a trailer, in which the tractor itself drives a plurality of hydraulic motors which control a crane unit, a coiled tubing injection unit, and the pumps and motors associated with a liquid nitrogen system which is used for injecting gaseous hydrogen into a workover well with coiled tubing. In an alternative mode, the liquid nitrogen system is replaced with nitrogen generators or tanks of compressed nitrogen gas. In another alternative embodiment, a separate engine, preferably mounted with the other equipment on a trailer, skid, or barge, replaces the single tractor engine for driving the plurality of hydraulic motors. In yet another embodiment, a single engine drives a plurality of well treating systems on an off-shore installation.
摘要翻译：提供单个拖拉机单元用于牵引拖车，其中拖拉机本身驱动多个液压马达，其控制起重机单元，连续油管注入单元以及与用于喷射的液氮系统相关联的泵和马达气态氢气进入带有连续油管的修井井。在替代模式中，液氮系统被氮气发生器或压缩氮气罐替代。在另一替代实施例中，优选地将其他设备安装在拖车，滑行或驳船上的单独的发动机代替用于驱动多个液压马达的单个拖拉机发动机。在另一个实施例中，单个发动机在离岸装置上驱动多个井处理系统。
