提高效率仍然是石油领域的首要任务。幸运的是,现在有比以往更多的方法来实现这一目标并最终提高利润。这些进步不仅提高了业绩,还使石油和天然气服务公司更具竞争力。

这些新的压裂技术可以在每个盆地使用,并且其中许多技术可以结合起来产生巨大的协同效应。

同步压裂作业

随着公司不断加大设备投入并延长泵送时间,非生产时间 (NPT) 会威胁盈利能力。这引起了人们对同时压裂完井技术的兴趣。

同步压裂操作很有吸引力,因为它们使操作员能够在更短的时间内完成更多阶段。同步压裂完井技术不是一次泵送一口井,而是允许公司用一个车队同时泵送两口水平井,从而使泵送时间立即加倍。与拉链压裂技术相比,这使公司能够最大限度地减少 NPT 并最大限度地提高横向进尺增益和节省,从而实现效率提高多达 60% 。

电子压裂

由于泵送时间已增加到几乎连续(通常每天 18 至 22 小时),因此显然需要提高性能,同时减少 NPT。从效率的角度来看,电子压裂泵具有最大马力和最少泵的独特优势。凭借单个装置的高马力容量,例如 5,000 马力连续工作 SPM™ QEM 5000 E-Frac 泵,压力泵送公司可以体验到与传统泵相同水平的正常运行时间,并且泵数量少得多。这种高马力密度,每天 24 小时在 100% 的道路负载下运行,意味着 8 个 5,000 马力的泵可以与 20 个传统泵的输出相匹配。 

高效 (HE) 压裂技术可以在同步压裂设置中利用,以实现更高的效率并节省成本。

最少的维护

接近连续工作的操作不允许任何类型的 NPT(包括维护)有太多余地。这催生了 QEM 系列等压力泵设备。这种新设备特别坚固,经过专门设计,可以以更少的维护间隔运行更长的周期,同时还可以承受由于现场团队维护各种复杂设备而导致的不规则维护实践。泵架和磨损部件的改进有助于减少框架破裂和轴承磨损,从而延长使用寿命,帮助操作员远离红区并减少计划外维护问题。

与经验丰富、技术精湛的服务提供商合作可以帮助压力泵工找到维护不足和过度支出之间的最佳平衡点,而过度支出可能会导致宝贵的正常运行时间减少。例如,与 SPM™ Edge Services 合作可提供工程驱动的专业知识,指导现场工作人员充分利用周期较长的设备,从而更加努力地推动工作并获得更大的收益。

更持久的消耗品

减少维护不仅可以降低 NPT,还可以降低成本。由于消耗品是压裂现场最大的维护费用之一,并且其更换会影响泵送时间,因此找到尽量减少液力端维护的方法可以帮助石油和天然气公司实现更高的效率。采用 SPM™ EdgeX™ 硬质合金座椅等新型座椅技术,经现场验证,与传统座椅相比,座椅寿命平均延长六倍,可大幅减少因现场更换而造成的停机时间以及费用。除了延长使用寿命外,EdgeX 的硬质合金增强阀座还可保护高磨损区域,同时安装标准锥形流体端。

众所周知,维护和意外的 NPT 会对泵送时间和利润产生负面影响。可以利用并结合重大的技术进步和新颖的垫设计方法来显着提高现场效率。运营商通过采用其中一项或全部技术进步可以实现性能改进,可以产生影响,这反映在公司的利润中。

Efficiency gains remain a priority in the oil patch. Fortunately, there are more ways than ever to accomplish this goal and ultimately improve profits. These advances not only enhance performance but also enable oil and gas service companies to be more competitive.

These new frac technologies can be leveraged in every basin, and many of them can be combined to create great synergies.

Simul-Frac Operations

As companies continue to push their equipment harder and pump longer hours, nonproductive time (NPT) threatens profitability. This contributes to interest in the simul-frac completion technique.

Simul-frac operations are attractive as they enable operators to complete more stages in less time. Rather than pumping one well at a time, the simul-frac completion technique allows companies to pump two horizontal wells at the same time with a single fleet—immediately doubling pumping time. This enables companies to minimize NPT and maximize lateral footage gains and savings to realize efficiencies improvements by as much as 60% compared to the zipper frac technique.

E-Frac

As pumping hours have increased to be nearly continuous—regularly clocking in at 18 to 22 hours per day—the need to increase performance while reducing NPT is evident. From an efficiency perspective, e-frac pumps offer a distinct advantage with maximum horsepower and minimal pumps. With high-horsepower capacity in a single unit, such as the 5,000-hp continuous-duty SPM™ QEM 5000 E-Frac Pump, pressure pumping companies can experience the same level of uptime as with conventional spreads—and with far fewer pumps. This high-horsepower density, running at 100% of road load 24 hours a day, means eight 5,000-hp pumps can match the output of 20 conventional pumps. 

High-efficiency (HE) frac technologies can be leveraged in simul-frac settings to realize even greater efficiencies and cost savings.

Minimal Maintenance

Near continuous-duty operations don’t allow much margin for NPT of any kind—including maintenance. This has given rise to pressure pumping equipment like the QEM Series. This new equipment is especially robust and specifically engineered to operate longer cycles with fewer maintenance intervals, while also withstanding irregular maintenance practices due to field teams maintaining a complex variety of equipment. Improvements in pump frames and wear components help reduce frame cracking and bearing stripping for longer life, helping operators stay out of the red zone and reducing unplanned maintenance issues.

Working with experienced and technically skilled service providers can help pressure pumpers identify the sweet spot between inadequate maintenance and excessive spending, which can cause a decrease in valuable uptime. Partnering with SPM™ Edge Services, for example, provides engineering-driven expertise that guides field crews to gain the full benefit of longer cycle equipment so they can push harder and make bigger gains.

Longer-lasting Consumables

Reduced maintenance not only lowers NPT, but it also lowers costs. As consumables represent one of the largest maintenance expenses on a frac site and their replacement impacts pumping hours, identifying ways to minimize fluid end maintenance can help oil and gas companies achieve greater efficiencies. Employing new seat technology like the SPM™ EdgeX™ Carbide Seat, which is field proven to increase seat life an average of six times compared to conventional seats, can substantially reduce the downtime caused by field changeouts as well as expenses. In addition to its enhanced longevity, the EdgeX’s carbide-reinforced seats protect high-wear areas while fitting standard taper fluid ends.

Maintenance and unexpected NPT are known to negatively affect pumping hours and profits. Significant technological advances and novel approaches to pad design can be leveraged—and combined—to significantly increase efficiency gains in the field. The performance improvements operators can realize by employing one or all of these technological advancements can make a difference that’s reflected in companies’ bottom lines.
