在FlowGun的帮助下,完井作业变得更加简单。

编译:惊蛰

Nine能源服务公司的FlowGun完井系统提供了无需干预、套管送入的射孔技术,利用这种突破性的系统,开发商可以获得更高的效率、控制能力以及作业灵活性。

FlowGun完井技术是一种高效灵活的工具,拥有压力激活的趾端滑套,无需使用钢丝绳或连续油管。FlowGun系统在北美各地应用了数百次,射孔枪点火成功率接近100%。

射孔工具的作用是创造出孔眼,作为名副其实的创新产品,Nine公司FlowGun完井系统可为首个射孔段提供安全且极具经济效益的完井作业。这种套管送入的射孔技术,无需干预作业,作业效率相比于同类技术更高。

与传统的裸眼多级投球射孔系统相比,FlowGun可在已固井的水平井筒内精确控制作业位置,大幅提高了作业精确度。射孔枪可以按要求的间隔,安装在套管管柱上。激活后,FlowGun系统无需下入电缆或连续油管,也无需电子点火。它拥有以下优点:提高生产效率;机械可靠性更高;完井作业更快;卓越的安全性。

使用FlowGun,可以将井眼延深至18000英尺以上,超过了连续油管与钢丝绳的作业极限。该系统即插即用,可以配置为下入单个或多个模块。无需移动滑套,暴露地层。没有作业限制,仍能提供卓越的性能。

在该系统的帮助下,井筒投产更快。下入底部钻具组合,将FlowGun射孔枪输送至目标深度。固井后,首先通过压力激活与射孔弹点火。在四小时内,即可对井口装置与井筒进行试压,引爆射孔枪,然后对首个压裂段进行酸化作业。

该系统还能增强作业过程每一步的安全性。FlowGun可提供高度控制的射孔过程,有助于提高控制能力与安全性,避免井场潜在风险。无需电子雷管,就不会有井口或过早点火的危险。其没有采用电子方式点火,从而消除了杂散电压引起的过早点火。FlowGun技术通过以下方式进一步提高了作业的安全性:减少空中吊物;减少现场作业人员数量;减少货运时间与第三方服务;尽量减少对环境的影响。

对比其它增产技术,FlowGun完井系统是一种无需额外干预作业的创新技术,其仅需一个工具与一个作业队即可执行多个井下作业,大幅提高了作业效率。凭借其精确性、灵活性与可靠性,FlowGun有助于降低成本、加强压裂作业的控制、提高井场安全、提高建井至投产的效率。当着手进行新的水平井钻进时,Nine公司的FlowGun可帮助开发商实现目标。

截至目前,已经安装了数百套FlowGun系统,达到了100%的点火成功率。事实上,首个压裂段中进行的射孔作业,基本所有地层都被射穿,只有一个在经过多次尝试射孔后,仍然没有成功射穿。

FlowGun以更低的成本提供更好的解决方案,选择FlowGun来替代传统的电缆或连续油管方案,可以获得更高效的射孔作业。更好的是,可以省掉完井流程中的一个环节,节约了相关成本。而且,这意味着无需额外的水、运输、防喷器租赁、连续油管、化学品、井队与劳动力。根据您的应用要求,FlowGun有两种型号可供选择。

技术特点

  • 割缝趾端滑套拥有可靠的压力承受能力;
  • 压力激活系统避免了井口或过早点火的风险;
  • 所有组件都经过严格检查,每个组件都有详细的检查表;
  • 减少作业人员数量,简化基础设施,将环境影响降至最低。

因为已经省掉了完井流程中一个完整环节,所以节约的作业时间非常可观。从开始对井筒进行压力测试,射孔枪点火,到建立进入储层的通道,所需时间不超过一小时。在一天内,我们的客户完成了多达6次完井作业,与需要洗井的标准TCP作业相比,其作业速度加快了6倍。

Completions just became infinitely easier. The FlowGun well completion system from Nine Energy Service offers completely interventionless, casing-conveyed perforating technology. In one groundbreaking system, you now have greater efficiency, control and flexibility

Efficiency and flexibility in one tool

FlowGun? Completion Technology from Nine features a pressure-activated toe sleeve that eliminates the need for wireline or coiled tubing。

Over 95% rate of successful detonation

after installing hundreds of FlowGun Systems across North America。

Blowing holes in the preconceptions of what a perforating tool can be

A true innovation, the FlowGun well completion system from Nine offers a safe and cost-effective advantage to your stage-1 completions. Completely interventionless, this casing-conveyed perforating technology offers infinite efficiency, control, and flexibility.

ON-TARGET PERFORATION

The FlowGun boosts the efficiency of a traditional open hole, multistage ball drop perforating system by allowing greater frac location control within a cemented horizontal wellbore. Perforation modules can be deployed at desired intervals along the casing string, and fracs initiate during the installation of the liner. Pressure-activated, the FlowGun system eliminates the need to run wireline or coil tubing and requires no electronic detonation. It provides:

  • Enhanced production efficiency
  • Greater mechanical reliability
  • Faster completions
  • Superior safety

EXTENDED CAPABILITIES

With FlowGun, you can extend your wellbore reach past 18,000 feet, beyond coil-tubing and wireline limitations. Much like a plug ‘n’ perf design, the system can be configured to convey a single or multiple modules. No sleeves to shift, exposing formation. No wet shoe required. Just unfettered operational performance.

A FASTER PATH TO PRODUCTION

The bottom hole assembly is conveyed into the wellbore, taking FlowGun clusters to targeted depths。 After the wellbore is cemented, the first stage is pressure activated and perf charges are fired。 In four hours, you can pressure test surface iron and wellbore, detonate guns, displace acid and place stage one。

ENHANCED SAFETY, EVERY STEP OF THE WAY

Offering a highly controlled perforating process, the FlowGun system can help you enhance safety and mitigate wellsite hazards。 With no electronic detonators, there’s no risk of surface or premature detonation。 FlowGun clusters cannot detonate electronically, eliminating premature firing due to stray voltage。 FlowGun technology further supports safe operations by:

  • Reducing overhead loads
  • Requiring fewer wellsite personnel for operation
  • Reducing trucking hours and third-party services
  • Minimizing environmental impact

INTERVENTIONLESS INNOVATION

The FlowGun well completion system manages several downhole jobs with one tool and one crew—dramatically boosting efficiency by eliminating an entire phase of the completion process. Offering accuracy, flexibility and reliability, the FlowGun can help:

  • Reduce costs
  • Increase frac control
  • Enhance wellsite safety
  • Improve rig-to-market efficiency

When you’re ready for a new direction in horizontal drilling, the FlowGun from Nine can get you there。

A PROVEN PERFORMER

We have installed hundreds of FlowGun systems, achieving a 100 percent rate of successful detonation. In fact, of the jobs set up for a first full stage, all but one were successfully fracked—and that one was still unsuccessful after numerous re-perf attempts.

BETTER SOLUTION AT A LOWER COST

By choosing FlowGun over traditional wireline or coil-tubing solutions, you’re getting a solution that’s statistically more effective. Better yet, you eliminate an entire phase of the completion process, along with all the associated costs. That means you’re not paying for additional water, tank trucking, BOP rental, coil tubing, chemicals, crew and labor. Contact your local sales representative for pricing.

TWO GUNS, NO CONTEST

The FlowGun comes in two available models, based on your application requirements.

Features

  • Perforated toe sleeve features industry-proven pressure-test function
  • Pressure activated system eliminates the risk of surface or premature detonation
  • All components rigorously inspected, with detailed checklists for every assembly
  • Reduced crew and infrastructure minimizes environmental impact

What is FlowGun’s success rate?

We have installed hundreds of FlowGun systems and have achieved greater than a 95 percent rate of successful detonation—100 percent with our newest model. In fact, of all the jobs set up for a first full stage, all but one were successfully fracked—and that one was still unsuccessful even after numerous re-perf attempts.

How does the FlowGun system detonate?

Instead of electric charges, the FlowGun System uses pressure-actuated detonation. This means there is no risk of surface or premature detonation. FlowGun clusters cannot detonate electronically, eliminating the possibility of premature firing due to stray voltage.

How much time will I save?

Considerable, given that you have eliminated an entire phase of the completion process. From the time you begin the pressure test of the wellbore, through detonation, to reservoir access takes less than one hour. In one day, our customers have finished as many as six completions, which is roughly six times faster than a standard TCP with cleanout.
