关于高含硫油气井相关技术标准点滴思考与建议

Suggestions on Related Technical Standards for High Sulfurous Oil and Gas Wells

现行有效的国家标准、行业标准、企业标准、企业文件中,对"高含硫油气井"给出了截然不同的定义,从150mg/m^3(100ppm)、1500mg/m^3(1000ppm)到30g/m^3(20000ppm)不等。从标准的层级、法律约束关系来说,无论是行业标准,还是企业标准、企业文件,应执行国家标准的最低要求。基于不同层级标准或文件中"高含硫油气井"定义的差异,本文从硫化氢特性和危害分析入手,横向对比国际标准、国家标准、行业标准和企业标准;通过对不同层级标准的研究,笔者认为国家标准将"高含硫油气井"定义为地层天然气中硫化氢含量等于或大于1500mg/m^3(1000ppm)的井是合理的,行业标准、企业标准、企业文件中"高含硫油气井"定义可以高于国家标准,但不能低于该国家标准的最低要求。

Different definitions of"high sulfurous oil and gas wells*'are given in the current effective national standards,industry standards,enterprise standards and enterprise documents,ranging from 150 mg/m^3(100 ppm),1500 mg/m^3(1 OOOppm)to 30 g/m^3(20 000 ppm).From the level of standards and legal constraints,the minimum requirements of national standards should be implemented in industry standards,enterprise standards,and enterprise documents.Based on the different definitions of"high sulfurous oil and gas wells"in different levels or documents,this paper starts with the analysis of characteristics and hazards of hydrogen sulfide,and compares the international standards,national standards,industry standards and enterprise standards horizontally.After the study of different levels of standards,the conclusion is made that it is reasonable that the national standards define"high sulfurous oil and gas wells"as the well with hydrogen sulfide content equal to or greater than 1500mg/m^3(1 OOOppm)in formation gas.The definition of"high sulfurous oil and gas well"in industry standard,enterprise standard and enterprise document can be higher than national standard,but not lower than the minimum requirement of national standard.
