卡特彼勒石油与天然气公司宣布开发卡特彼勒气体机械系统 (GMS)，该系统使用 100% 天然气，旨在提高压裂作业的机械效率和简便性。

GMS 专为高马力压力泵送应用而设计，配备 3600 马力 Cat G3520 发动机和 TH55G-E90 变速箱。与其他压裂作业方法相比，其可扩展设计减少了现场拖车数量，提高了每辆拖车的功率密度，并降低了燃料消耗。

目前在二叠纪盆地进行的现场测试表明，GMS 的产量高达每分钟 13 桶，同时每天可维持超过 20 小时的抽油时间。GMS 将继续在北美主要盆地进行测试。

Caterpillar Oil & Gas announced the development of the Caterpillar Gas Mechanical System (GMS), built for mechanical efficiency and simplicity in frac operations, using 100% natural gas.

Engineered for high-horsepower pressure pumping applications, the GMS features the 3600 hp Cat G3520 engine and TH55G-E90 transmission. Its scalable design requires fewer trailers on-site, increases the power density per trailer, and decreases fuel consumption, compared to alternative frac operation methods.

Current field testing in the Permian Basin has shown the GMS achieving production rates up to 13 barrels per minute while sustaining over 20 pumping hours per day. The GMS will continue to be tested across major North American basins.
