H&P 正在为其钻机车队引入卡特彼勒油气公司的第二代 Cat 动态气体混合 (DGB) 套件。DGB 第二代套件旨在改造现有发动机，包括 Cat 3512C，最大限度地提高发动机效率，同时减少昂贵的发动机更换需求。 

该系统采用先进的进气道喷射技术，优化气缸内的空燃比，最大限度地减少甲烷逃逸，并提高热效率。该技术使H&P发动机的柴油排量高达75%，从而节省燃油成本，并有助于减少温室气体排放。

此外，Cat 智能发动机管理系统的实时发动机控制集成可以优化发动机的运行。

在鹰福特进行的现场试验已经证明了该套件的高效性，在九个月内平均可替代65%的柴油。在峰值性能下，排量达到75%，在单台钻机上节省了超过94,000加仑的柴油，发动机运行时间超过4,500小时。

目前计划在 2025 年底前将 DGB Gen 2 Kit 集成到 FlexRig 车队的 60 多台发动机中。

“这次升级是双赢的。它让我们能够更好地利用现有发动机，同时降低燃油成本和排放，”H&P 美洲运营高级副总裁 Mike Lennox 表示。“运营商需要实用的解决方案，不需要对整个机队进行大修，而 DGB Gen 2 套件正好满足了他们的需求。”

H&P is introducing the Cat Dynamic Gas Blending (DGB) Gen 2 Kit by Caterpillar Oil & Gas to its drilling rig fleet. The DGB Gen 2 Kit is designed to retrofit existing engines, including the Cat 3512C, maximizing engine efficiency while reducing the need for costly engine replacements. 

By utilizing advanced port-injection technology, the system optimizes the air-to-fuel ratio in the cylinder, minimizing methane slip and improving thermal efficiency. This technology allows H&P to achieve up to 75% diesel displacement, delivering cost savings on fuel and contributing to the reduction of GHG emissions.

Further, the integration of real-time engine controls from the Cat Smart Engine Management System enables optimization of engines operations.

Field trials in the Eagle Ford have already demonstrated the kit’s efficiency, displacing an average of 65% diesel over nine months. At peak performance, displacement reached 75%, saving over 94,000 gallons of diesel on a single rig with more than 4,500 engine hours.

Plans are under way to integrate the DGB Gen 2 Kit into more than 60 engines in the FlexRig fleet by the end of 2025.

“This upgrade is a win-win. It lets us get more out of our existing engines while cutting fuel costs and emissions,” said Mike Lennox, H&P SVP Americas Operations. “Operators need practical solutions that don’t require overhauling their entire fleet, and the DGB Gen 2 Kit gives them exactly that.”
