【摘要】 我国天然气工业处于快速发展阶段,“十一五”期间特别要大力发展和创新低渗砂岩气藏、深层异常高压气藏、多层疏松砂岩水驱气藏、高含硫气藏和深层凝析气藏开发开采技术。文章就其中一些复杂气藏的开发问题提出了10条建议,希望能拓展新思路,特别关注一些我国还未应用的工艺技术,包括水驱气藏注N2或聚合物粘稠液阻水治水技术、水驱气藏与凝析气藏开发后期注N2技术、凝析气藏提高气藏采收率和单井产量的各种技术。另外,发展我国压缩机装备和注气技术、加强与俄罗斯为首的独联体国家石油天然气科技交流也至关重要,成组气田开发和低渗气藏试井及动态分析工作等也应受到重视。更多还原

【Abstract】 China’s gas industry has entered the fast development phase. During the "11th Five Year Plan", great efforts should be put on advancement and innovation of the development and production technologies of complex gas reservoirs, such as low permeability sandstone gas reservoirs, deep surpressure gas reservoirs, water drive multilayer unconsolidated sandstone gas reservoirs, acid gas reservoirs and deep condensate reservoirs. Ten proposals are presented on the development of some complex gas reservoirs. It is hoped to expand new ideas and pay special attentions to some new techniques that have not been applied in China, such as water blocking and control technique through injecting N₂ or viscous polymer solutions in water drive gas reservoirs, N₂ injection techniques in late development stage of water drive gas reservoirs and condensate reservoirs, as well as various approaches to enhance recovery factor and individual well production rate of condensate reservoirs. Moreover, it is also very important to develop our own compressor and gas injection techniques and strengthen scientific and technical exchange with the members of Community of Independent States headed by Russia. Equal attentions should also be paid to the development of interconnecting gas fields and well testing and performance evaluation of low permeability gas reservoirs.更多还原
