摘要

油气生产井的成功设计和交付需要跨多个领域的高度协作。面临的挑战各不相同,包括来自邻井分析的风险评估、特定领域的工作流程和实践、地质问题和局限性、选择的工程技术、成本考虑以及环境和安全问题。团队成员(如管理人员、地球科学家、钻井工程师、泥浆工程师、定向钻工、供应商和顾问)之间的合作水平不佳,通常会对井的质量或成本产生负面影响。在一个案例研究中,云技术的应用和分析表明,如何显著降低井规划成本,从而增强团队协作,改善工程设计过程。数字井建设规划解决方案使油气运营商能够通过以下方式轻松管理项目:简化钻井和作业团队成员之间的任务分配,改进过程状态跟踪,记录每个任务的历史进度,并开放使用行业领先的工作流程和引擎。这种部署在云端的数字井建设规划解决方案包括一个项目管理结构,有助于任务的分配、审查和批准。地球科学家和工程师可以登录数字井建设规划解决方案,完成特定任务,然后与项目的其他人员共享完成的任务。这使得其设计考虑具有依赖性的其他团队成员能够将整体的和具有代表性的设计标准合并到他们自己的工作流中。该过程是平滑的、并发的和常绿的,并且所有任务在输出级别和工程级别都是共享的。这种方法确保项目数据、工作流和工程分析始终是最新的。有了这种新的解决方案,井的规划时间可以从几天缩短到几个小时。项目经理可以很容易地跟踪每个任务的状态,而不需要来回的电话交谈或电子邮件。在非常规井中,同一地区的井设计通常相似,因此可以使用模板和项目复制功能将设计复制到下一口井,从而加快设计过程。在为新项目执行项目复制或模板导入后,可以在共享后生成工程验证。轨迹可以自动设计,结合防碰撞考虑、地质目标、井面位置和其他设计约束。然后,对井的水力、扭矩和阻力分析、底部钻具组合(BHA)趋势和套管设计进行验证,以确保井的可钻性和成本效益。该数字井施工规划解决方案可以帮助作业者按时交付安全、经济高效的井,并执行高质量的井规划。

Using Cloud Technology to Improve Unconventional Well Planning by Enhanced Collaboration and Automated Engineering Design
The successful design and delivery of oil and gas production wells require significant levels of collaboration across multiple domains. The challenges encountered vary widely, and including risk evaluations from offset well analysis, domain-specific workflows and practices, geological concerns and limitations, engineering technology of choice, cost considerations, as well as environmental and safety concerns. Suboptimal levels of collaboration among team members, such as managers, geoscientists, drilling engineers, mud engineers, directional drillers, suppliers, and consultants, often negatively impact the quality or cost of the well. The application and analysis of a cloud technology in a case study shows how the cost of well planning can be significantly reduced, which enhances team collaboration and improves the process of engineering design. The digital well construction planning solution enables oil and gas operators to manage projects easily by: simplifying task assignment among drilling and operations team members, improving process status tracking, documenting the historical progress of each task, and opening access to industry-leading workflows and engines. This digital well construction planning solution which is deployed in the cloud, includes a project management structure, aiding with the assignment, review, and approval of tasks. Geoscientists and engineers can log in to the digital well construction planning solution, finish specific tasks, and then share the completed tasks with the rest of the project. This enables other team members whose design considerations have dependencies to incorporate holistic and representative design criteria into their own workflows. The process is smooth, concurrent, and evergreen, and all tasks are shared at both the output level and the engineering level. This approach ensures that the project data, workflows, and engineering analysis are always current. With this new solution, well planning time can be reduced from several days to a few hours. The project manager can easily track the status of each task without back-and-forth phone conversations or e-mails. With unconventional wells, where the well designs are often similar in the same region, template and project copy functions can be used to duplicate designs to the next well and accelerate the design process. After a project copy or template import is executed for a new project, the engineering validations can be produced after being shared. Trajectories can be designed automatically, incorporating anti-collision considerations, geological targets, well surface locations, and other design constraints. Then, well hydraulics, torque and drag analysis, bottomhole assembly (BHA) tendencies, and casing designs are validated to make sure the well is drillable and cost-effective. This digital well construction planning solution can help operators deliver safe, cost-effective wells on time, and execute high-quality well planning.
