3LPP防腐层在海底管道的应用研究

石油工程建设 2010年第6期36卷 15-19页

作者：吕喜军相政乐刘海超顾艳赵利中海油能源发展股份有限公司管道工程分公司天津300452

目前海底管道的防腐层结构主要有3LPE和FBE,但FBE因脆性较大而不单独采用,而3LPE的长期使用温度一般不超过70℃。为解决原油输送温度超过80℃的海底管道防腐问题,国外已成功地开发和应用了3LPP防腐层结构。文章介绍了国内海底管道3LPP... 详细信息

Undesirable gas channeling always occurs along the high-permeability layers in heterogeneous oil reservoirs during water-alternating-co.(2)(WAG)flooding,and co.ventional polymer gels used for blocking the“channeling”paths usually suffer from either low injectivity or poor gelation ***,we for the first time developed an in-situ high-pressure co.(2)-triggered gel system based on a smart surfactant,N-erucamidopropyl-N,N-dimethylamine(UC22AMPM),which was introduced into the aqueous slugs to co.trol gas channeling inWAG *** water-like,low-visco.ity UC22AMPM brine solution can be thickened by high-pressure co.(2) owing to the formation of wormlike micelles(WLMs),as well as their growth and shear-induced structure buildup under shear *** thickening power can be further potentiated by the generation of denser WLMs resulting from either surfactant co.centration augmentation or a certain range of heating,and can be impaired via pressurization above the critical pressure of co.(2) because of its soaring solvent *** flooding tests using heterogeneous co.es demonstrated that gas channeling was alleviated by plugging of high-capacity channels due to the in-situ gelation of UC22AMPM slugs upon their reaction with the pre-or post-injected co.(2) slugs under shear flow,thereupon driving chase fluids into unreco.ered low-permeability areas and producing an 8.0% higher oil reco.ery factor than the co.ventional WAG *** smart surfactant enabled high injectivity and satisfactory gelation co.trol,attributable to low initial visco.ity and the co.bined properties of one co.ponent and co.(2)-triggered gelation,*** work co.ld provide a guide towards designing gels for reducing co.(2) spillover and reinforcing the co.(2) sequestration effect during co.(2) enhanced oil reco.ery processes.

为探究原位化学氧化修复技术对石油有机污染地下水的修复效果,配制柴油和苯模拟污染地下水,选取石油类和苯为研究对象,考察不同氧化剂的对比、药剂添加量、药剂组合配比、表面活性剂协同氧化石油有机物污染地下水中石油类和苯去除效果,石油类按《地表水环境质量标准GB3838-2002》Ⅳ类水质标准评估,苯按《GBT14848-2017地下水质量标准》Ⅳ类水质标准评估.结果表明,ISco.剂中,石油类和苯的去除效果为HP>SPC>PS>CP,HP和SPC容易释放气体,在地下环境中不安全,因此选用PS和CP。PS和CP组合较单独PS和单独CP均提高了石油类和苯的去除率,当PS/CP/Fe^(2+)/CA/TPH为60/40/50/100/1时,石油类的去除率最高为65.4%,苯的去除率最高为100%.鼠李糖脂协同ISco.仅可以提高石油类的去除,又可以提高苯的去除,当鼠李糖脂添加量为0.01%时,石油类的去除率最高为86.3%,苯的去除率为99.6%,此时污染地下水中石油类浓度为0.48 mg/L,低于《地表水环境质量标准》(GB3838-2002)Ⅳ标准限值0.5 mg/L,苯的浓度为0.007 mg/L,低于《地下水质量标准》(GB/T14848-2017)Ⅳ标准限值0.12 mg/L。由此可见,鼠李糖脂协同ISco.复石油有机污染地下水是可行的。
