【摘要】：本项目在充分查阅文献和调研的基础上,利用理论与经验公式计算、气体爆炸实验、气体爆炸后果模拟、有害危险因素分析等方法,分别研究了给定组分原油伴生气理论爆炸参数、伴生气燃爆实验、油管内低温氧化爆炸危害模拟、防止爆炸事故的工艺安全措施及安全设备配备方案等4项内容。(1)理论计算和实验研究分别得到了不同初始温度和初始压力下吉林油田空气驱试验区原油伴生气爆炸极限的理论值和实验值。(2)通过AutoReaGas模拟软件的模拟,结果表明油管内爆炸超压值与初始温度有着密切的关系,初始温度升高能够导致爆炸峰值超压发生显著的变化,最高可达450 MPa以上,对油管和井口等设施造成严重破坏,在远离爆炸区域的管段内,压力变化并不太明显。此外爆炸仅造成了爆炸区域和附近管段内温度的急剧升高,对远距离作用较弱。(3)分析了注气管内发生可燃气体爆炸时,主要以爆炸冲击波和破片两种形式对人员和设施产生危害。(4)研究分析低温氧化注气过程中空气压缩机、注气管线、注入井筒、生产井筒的危险性及各类事故发生的原因,并提出防止爆炸等事故的工艺安全措施。初步提出了预防爆炸事故发生的安全设备与设施配备方案。
[Abstract]:On the basis of full literature review and investigation, the project uses methods such as theoretical and empirical formulas, gas explosion experiments, simulation of gas explosion consequences, analysis of harmful risk factors, etc. The theoretical explosion parameters of crude oil associated with the given component, the associated gas explosion experiment, the hazard simulation of low temperature oxidation explosion in the tubing are studied respectively. The theoretical calculation and experimental study on the process safety measures and safety equipment configuration schemes for preventing explosion accident have obtained the crude associated gas explosion in the air drive test area of Jilin Oilfield under different initial temperature and initial pressure, respectively. The theoretical and experimental values of the explosion limit are simulated by AutoReaGas software. The results show that the value of explosion overpressure in tubing is closely related to the initial temperature, and the increase of initial temperature can lead to a significant change of the explosion peak overpressure, the maximum value of which can reach more than 450 MPa, causing serious damage to the tubing and wellhead facilities, etc. In the tube section far away from the explosion area, the pressure change is not obvious. In addition, the explosion only causes the sharp rise of the temperature in the explosion area and nearby pipe segment. Mainly in the form of blast wave and fragment, the hazard to personnel and facilities is studied and analyzed. The risk of air compressor, injection pipe line, injection wellbore, production wellbore and the causes of all kinds of accidents in the process of oxidizing gas injection at low temperature are studied and analyzed. The technical safety measures for preventing explosion and other accidents are put forward, and the scheme of safety equipment and facilities for preventing explosion accidents is put forward preliminarily.
