准噶尔盆地煤层气产业化对策

摘要/Abstract

摘要： 准噶尔盆地煤层气资源丰富，富集地区和有利勘探目标主要位于盆地南缘东部乌鲁木齐—白杨河一带；工程技术适应性研究表明，应优选适合准噶尔盆地煤层气排采制度和主体压裂改造工艺；煤层气单井极限产量研究确定，在目前气价下，钻探深度应小于1000m，单井固定资产投资小于800 万元。对煤层气产业发展环境、风险及对策进行分析研究，认为目前中国煤层气开发利用政策框架初步形成，陆续出台了打破专营权、税收优惠、财政补贴等多项扶持政策，且已形成规模开发的态势。新疆出台了一系列煤层气产业发展的利好政策，并在白杨河地区成功建成 ^“煤层气开发试验区^”。中国石油也将非常规油气作为上游开放的重要领域，并出台了针对新疆的具体指导意见。这些有利的政策环境为准噶尔盆地煤层气产业发展提供了有力支持。针对煤层气地质选区和开发效益的风险，提出采取合资合作方式进行煤层气勘探开发是当前煤层气产业发展最现实的选择。

Abstract: Junggar Basin is rich in coal-bed methane (CBM) resources. The abundance zones and main favorable exploration targets are located in the eastern Urumqi –Baiyanghe area on the southern periphery of the basin. Based on the study of engineering technological adaptability, it is necessary to use the fracturing and renovation process suitable for extraction of CBM in Junggar Basin. Under the present gas price, the drilling depth should be less than 1000 meters according to the study of the single-well CBM production ceiling. The investment in single-well asset should be less than 8 million yuan. Based on the study of the environment, risks and strategy of CBM industrial development, it is concluded that the policy framework of China^’s CBM development and application is preliminarily shaped at the present time with a series of supportive policies released, such as elimination of business exclusive franchise, preferential taxation and financial subsidies. The industry has been on the track of large-scale development. Xinjiang has released a series of favorable policies for CBM industrial development and successfully established^“the pilot CBM development zone^” in the Baiyanghe area. PetroChina has also emphasized non-conventional oil and gas as an important area in the upstream sector opening to the outside world and formulated the concrete guidance documents on CBM business in Xinjiang, creating favorable policy environment for CBM industrial development in Junggar Basin. To take into account the risks for CBM development performance, a co-funded cooperative CBM exploration pattern is proposed to be the most realistic option for CBM industrial development.
