【摘要】：本項目在充分查閱文獻和調(diào)研的基礎上,利用理論與經(jīng)驗公式計算、氣體爆炸實驗、氣體爆炸后果模擬、有害危險因素分析等方法,分別研究了給定組分原油伴生氣理論爆炸參數(shù)、伴生氣燃爆實驗、油管內(nèi)低溫氧化爆炸危害模擬、防止爆炸事故的工藝安全措施及安全設備配備方案等4項內(nèi)容。(1)理論計算和實驗研究分別得到了不同初始溫度和初始壓力下吉林油田空氣驅(qū)試驗區(qū)原油伴生氣爆炸極限的理論值和實驗值。(2)通過AutoReaGas模擬軟件的模擬,結(jié)果表明油管內(nèi)爆炸超壓值與初始溫度有著密切的關系,初始溫度升高能夠?qū)е卤ǚ逯党瑝喊l(fā)生顯著的變化,最高可達450 MPa以上,對油管和井口等設施造成嚴重破壞,在遠離爆炸區(qū)域的管段內(nèi),壓力變化并不太明顯。此外爆炸僅造成了爆炸區(qū)域和附近管段內(nèi)溫度的急劇升高,對遠距離作用較弱。(3)分析了注氣管內(nèi)發(fā)生可燃氣體爆炸時,主要以爆炸沖擊波和破片兩種形式對人員和設施產(chǎn)生危害。(4)研究分析低溫氧化注氣過程中空氣壓縮機、注氣管線、注入井筒、生產(chǎn)井筒的危險性及各類事故發(fā)生的原因,并提出防止爆炸等事故的工藝安全措施。初步提出了預防爆炸事故發(fā)生的安全設備與設施配備方案。
[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.
