技术领域 FIELD

本实用新型涉及在石油天然气钻井中模拟循环泡沫钻井用的一种可循环泡沫模拟实验装置。 A foam loop simulation apparatus according to the present invention relates to a foam simulation loop in drilling oil and gas drilling in.

背景技术 Background technique

泡沫流体技术始于20世纪50年代,国内在80年代开始泡沫流体钻井技术的研究和应用,并相继在新疆、胜利、辽河、大庆、长庆、四川等油田取得现场实践。 Foam fluid technology began in the 1950s, China began to study and application of foam drilling fluid technology in the 1980s, and have made the practice field in Xinjiang, Shengli, Liaohe, Daqing, Changqing, Sichuan and other oil fields. 泡沫流体由于具有与普通流体不同的独特结构,与常规泥浆钻井相比,泡沫钻井具有以下显著优点:1、提高钻速,延长钻头的使用寿命;2、钻井液漏失量低,可减少地层损害;3、携岩能力强,能有效地清除井底岩屑;4、油气显示明显;5、粘度高、静液柱压力低、可大大减少地层漏失。 Since the foam has a fluid different from the ordinary fluid unique structure as compared with the conventional drilling mud, foam drilling has the following significant advantages: 1, to improve the penetration rate, extend the life of the drill bit; 2, a low amount of drilling fluid loss, formation damage may be reduced ; 3, strong rock carrying capacity, can effectively remove cuttings downhole; 4, shows a clear oil; 5, high viscosity, low hydrostatic pressure, can greatly reduce the formation leakage. 因此,泡沬钻井技术在低压、低渗油气藏和易漏地层应用较多,是实现欠平衡钻井保护低压油气藏的最有效的方法之一,随着新老油田的开发,以泡沫作循环介质的钻井作业会不断增加。 Therefore, Foam drilling technology in many low-voltage, low permeability reservoir formation easy drain applications, underbalanced drilling is to achieve one of the most effective ways to protect low-pressure reservoirs, with the development of new and old oil fields to foam for recycling drilling medium will continue to increase.

专利CN200510078221.1介绍了钻井泡沫循环利用方法,将返至井口的泡沬直接导入密闭循环系统,在密闭条件下清除其中的岩屑,然后利用泡沫增压系统对其进行增压,使其压力达到需要的值,最后再使其进入入井管汇、实现循环利用。 Patent CN200510078221.1 of drill foam recycling method, Foam returned to the wellhead directly into a closed circulation system, which remove cuttings under sealed conditions and then the foam booster system be pressurized to a pressure reaches the desired value, and finally make it into the manifold into the well, to achieve recycling. 此外还有采用机械法消泡的专利介绍。 There are also methods using mechanical defoaming patent description. 由于目前缺乏在室内模拟循环泡沫钻井用的实验装置,所以研究在室内模拟循环泡沫钻井用的实验装置对泡沬钻井工艺技术发展,找出最佳的消泡方法具有重要意义。 Due to the current lack of experimental laboratory simulation cycle foam drilling, so research in experimental laboratory simulation foam drilling cycle is of great significance for the development of drilling technology Foam find the best anti-foaming method. 实用新型内容 SUMMARY
