【摘要】：在石油工程领域中,井控可以理解为井涌控制。在钻井期间一旦发现井涌并且无法控制的情况下,将会导致井喷,极可能造成油气井报废、火灾、施工设备损坏以及造成极其严重的环境污染等一系列事故,并且事故属于灾难性事故,危害程度相对较大。为此论文主要围绕适合油田井控防喷预警系统展开研发设计,对其展开研发设计具有一定的必要性。本论文中,实现了井控预警系统的研发设计工作,并且预警较为精准,具备一定的实用性与适用性。首先需要围绕井控检测展开全面而深入的需求分析工作,逐步落实研发设计方案,系统在研发设计方面,主要划分为两个研发设计部分。硬件设计实现了采集信号、信号处理等工作。在数据采集方面文章主要引用到超声波液位传感器、进出口流量传感器等设备实现,在数据分析、记录与处理方面主要结合了GPRS传输技术,警报系统方面实现了声光警报;关于系统软件部分主要通过数据建模后实现井控防喷预警系统的研发设计,实现人机交互界面、数据实时收集等方面功能。本系统对检测数据的判断以及发出的信号具备一定精准性,与此同时信号接收方面采取实现接收模式,操作方式采取触摸模式等,系统显示较为直观、较具可操作性,该系统预警较为精准并且易于推广。
[Abstract]:In the field of petroleum engineering, well control can be understood as well wellbore control. Once a well is discovered during drilling and is beyond control, it will lead to blowout, which will most likely lead to the abandonment and fire of oil and gas wells. A series of accidents, such as damage of construction equipment and extremely serious environmental pollution, are catastrophic accidents, and the degree of harm is relatively large. Therefore, this paper mainly focuses on the development and design of a well-controlled blowout prevention and warning system suitable for oil fields. It is necessary to develop R & D design for it. In this paper, the R & D design of well control early warning system is realized, and the warning is more accurate. It has certain practicability and applicability. First of all, it is necessary to carry out comprehensive and in-depth requirements analysis work around well control testing, and gradually implement the R & D design scheme, the system in R & D design, It is mainly divided into two parts of research and design. The hardware design realizes the work of collecting signal and signal processing. In the aspect of data acquisition, the article mainly uses ultrasonic liquid level sensor, flow sensor and other equipment to realize, in the data analysis, The recording and processing mainly combine the GPRS transmission technology, the alarm system realizes the acousto-optic alarm, the software part of the system mainly realizes the development and design of the well control blowout prevention and warning system after the data modeling, and realizes the man-machine interactive interface. The system has certain accuracy to judge the detection data and the signal sent out, at the same time, it adopts the receiving mode to realize the receiving mode, the operation mode to the touch mode and so on, at the same time, the system has the function of collecting the data in real time. The system display is more intuitive, more operable, the system warning is more accurate and easy to promote.
