Weir Oil & Gas白皮书：大限度地提高压裂泵的功率端寿命

75%-80%的压裂泵轴承故障与润滑系统有关;石油污染是大的原因。设计合理的润滑系统，创新技术，定期石油监测和及时换油可以显着提高泵的寿命，提高效率，降低运营支出。

首先，选用的润滑油要确保在整个工作范围内的适当粘度。其次，为特定气候设计的润滑系统在没有进行重要的设计参数评估前，包括石油类型和恒温器，不能在不同的气候条件下使用。 另外，有效的油冷却、过滤、输送压力和流速对于操作至关重要。

压裂泵的设计必须在全天候运行条件下提供更好的性能和可靠性。Weir集团泵产品首席工程师Ben Shuck以及高级工程师John McCrady进一步解释了这份白皮书的内容。

现代水力压裂作业对设备的要求日益严格。垫块钻井，全天候完井操作，更长的水位线，更多的阶段，更高的压力要求以及更大的油井支撑剂消耗量都大大提高了完井的运行强度。通过优化维护间隔来大化设备正常运行时间并降低成本需求的不断增长。

由于压裂泵是水力压裂作业中关键的设备之一，因此它们必须设计成能够在全天候的运行条件下提供更好的性能和可靠性，并能长期暴露于高速率，耐磨性，支撑剂载液等情况之下。虽然水力压裂可提供曾经被认为不可能进行生产的碳氢化合物，但继续降低运行压裂油泵的成本对于在紧张的市场上降低每桶石油的成本至关重要。

White Paper: Maximizing Frac Pump Power-End Life

75%–80% of frac pump bearing failures are related to the lubrication system; oil contamination is the single biggest cause. A correctly designed lubrication system, innovative technologies, regular oil monitoring, and timely oil changes can dramatically increase pump life, improve efficiency, and lower operating expenditure.

The lubricating oil is selected to ensure suitable viscosities across the entire operating range. Lubrication systems designed for a particular climate should not be used in a different climate without reviewing important design parameters, including the oil type and thermostat. Effective oil cooling, filtration, delivery pressure, and flow rate are critical to operations.

Frac pumps must be designed to deliver improved performance and reliability under 24/7 operating conditions. Ben Shuck, Pump Principal Engineer and John McCrady, Senior Engineer at Weir, explain further in this downloadable white paper.

Modern hydraulic fracturing operations are placing increasingly rigorous demands on equipment. Pad drilling, round-the-clock completion operations, longer horizontals, more stages, higher-pressure requirements, and greater proppant consumption per well have significantly increased the operational intensity of completions. There is growing demand to maximize equipment uptime and reduce cost by optimizing maintenance intervals.

Because frac pumps are one of the most crucial items of equipment in a hydraulic fracturing operation, they must be designed to deliver improved performance and reliability under the 24/7 operating conditions and extended exposure to high-rate, abrasive, proppant-laden fluids. While hydraulic fracturing has provided access to hydrocarbons once considered impossible to produce, continuing to lower the cost of operating a frac pump is critical to reducing the cost per barrel of oil in a tight market.
