卡特彼勒的燃气机械系统采用 100% 天然气运行，并结合了两个已在现场运行数百万小时的部件。
多年来为石油和天然气钻探作业提供动力的柴油发动机正在让位于运行效率更高、排放更少的天然气系统。
“大约 10 年前，大多数油井服务或水力压裂作业都采用 2,500 马力的柴油发动机，”卡特彼勒石油天然气解决方案钻井和完井产品经理 Andy Publes 说。
随后，发动机开始采用双燃料技术，最终实现了 85% 的柴油排量，比赛就此开始。

Caterpillar’s Gas Mechanical System runs on 100% natural gas and combines two components that have logged millions of hours in the field.
The diesel engines that have provided the power for oil and gas drilling operations for years are giving way to natural gas systems that run more efficiently with fewer emissions.
“About 10 years ago, most of the well services or hydraulic fracturing operations were running on 2,500-hp diesel engines,” said Andy Publes, drilling and completion product manager for Caterpillar Oil & Gas Solutions.
Engines then began using dual-fuel technology, eventually achieving 85% diesel displacement, and the race was on.
