Abstract

Wellheads have a major role in ensuring well integrity, providing access to the wellbore and flow control. It is vital to constantly monitor the wellhead fluid pressure and temperature effectively in order to maintain the full control of wellbore fluids. Over the years, wellheads have remained purely mechanical and have heavily relied on physical on-site monitoring. There is need to develop a reliable and accessible monitoring solutions for the wellheads in order to increase the effectiveness of the well integrity management systems and to get the full benefits of the wellhead data by incorporating the emerging data analytics technologies. This project details the development of a system that gathers wellhead temperature, pressure and the accurate valve position at any given time. The data gathering systems used in this project entail smart sensor technology capable of withstanding the wellbore pressures and temperatures. The system transmits the data securely, using blockchain, to an online platform where advanced data analytics using MATLAB and machine learning algorithms are used for visual data representation. The online platform additionally provides a means of real-time valve position control and takes into account the exact revolutions required for the opening and closure of the valve hence keeping a record for maintenance purposes. The innovative use and analysis of the data gathered form the wellhead provides insights for the operators and service companies and gives a way for setting ang thresholds in order to get alerts based in their custom specifications. This paper documents the development of a system that gathers wellhead data and provides a means of remote control of the wellhead valves. It covers the design phase, selection of appropriate sensor placement locations on the wellhead, the design of valve actuators, offline data gathering systems and the online data analysis and valve control platform. The project also pays a key attention towards the secure data transmission techniques and highlights the benefits of incorporating such a system in the oil and gas upstream sector.
井口远程控制与监测系统的研制
井口在确保井筒完整性、提供井筒通道和流量控制方面发挥着重要作用。为了保持对井筒流体的完全控制,持续有效地监测井口流体压力和温度至关重要。多年来,井口一直是纯机械的,严重依赖于物理现场监测。为了提高油井完整性管理系统的有效性,并通过结合新兴的数据分析技术,充分利用井口数据,有必要为井口开发一种可靠且易于使用的监测解决方案。该项目详细介绍了一个系统的开发,该系统可以在任何给定时间收集井口温度、压力和精确的阀门位置。该项目中使用的数据收集系统需要能够承受井筒压力和温度的智能传感器技术。该系统使用区块链将数据安全地传输到一个在线平台,该平台使用MATLAB和机器学习算法进行高级数据分析,用于可视化数据表示。在线平台还提供了一种实时阀门位置控制手段,并考虑到阀门开启和关闭所需的精确转数,从而为维护目的保留记录。从井口收集的数据的创新使用和分析为运营商和服务公司提供了见解,并提供了一种设置阈值的方法,以便根据他们的定制规格获得警报。本文记录了一种收集井口数据并提供井口阀门远程控制手段的系统的开发。它涵盖了设计阶段,在井口选择合适的传感器放置位置,阀门执行器的设计,离线数据收集系统和在线数据分析和阀门控制平台。该项目还重点关注安全数据传输技术,并强调将此类系统应用于油气上游行业的好处。
