克罗地亚西北部Molve、Kalinovac和StariGradac三气田采出气体中的H2S含量最高达320ppm,CO2含量最高达25.1mol%。本文叙述了这三个气田的完井及采气工艺,特别介绍了从优化采气工艺和保障安全两个角度出发所经历的完井工艺改进过程和改进方法,也着重谈了防腐材料的选择和应用。开采经历证明改进过程中所选用的材料、密封部件及气密螺纹接头是正确的,一直未发现因腐蚀或其他原因造成的明显损坏。 The H2S content of the gases produced in the Molve, Kalinovac and StariGradac fields in the northwestern part of Croatia is up to 320 ppm and the CO2 content is up to 25.1 mol%. This paper describes the completion and gas production processes of the three gas fields. In particular, it introduces the process of completion process improvement and the improvement methods that are experienced from the two aspects of gas production optimization and safety protection. The selection of anti-corrosion materials is also emphasized And application. The mining experience demonstrated that the materials, seals and gastight fittings selected for the improvement were correct and that no significant damage was found due to corrosion or other causes.
