摘要
基于非常规油气赋存特征、页岩气区块分布特点及国内外油气开发经验,提出"多期、多源、多气"联合勘探开发评价思路,并以鄂尔多斯盆地、四川盆地各类型气藏分布特征为例,阐述其应用设想。煤层气、页岩气、致密砂岩气及常规油气在上述盆地中均有分布,部分地区垂向叠置,以往各气藏勘探开发相互独立,造成地质资料重叠、勘探评价重复,提出的思路旨为新区(如页岩气区块)研究提供决策参考,应充分研究地质"多期",规划工程"多期",认清地质"多源",优化工程"多源",分析地质"多气",推进工程"多气",降低勘探成本,减少重复工作。
Based on unconventional oil and gas formation features, distribution features of the shale gas blocks and the domestic and overseas oil and gas development experiences, a valuation idea of the＂ multi phases, multi resources and multi gas＂ combined exploration and development was provided.Based on the different gas formation features of Ordos Basin ,Siehuan Basin and other type gas formation distribution features as the examples, the paper introduced the application ideas. The coalbed methane, shale gas, compact sandstone gas and conventional oil and gas would be distributed in above basins.In the partial regions, the formations would be vertically overlaid.Previously each gas formation was independently explored and developed, thus the geological information would be overlapped and the exploration evaluations would be repeated.The idea provided would be the decision references to the study on the new block （such as the shale gas block ）.In order to reduce the exploration cost and to reduce the repeated work, the study should be fully conducted on the ＂multi phases＂ of the geology and the planning engineering.The geological ＂multi resources＂ should be clarified ,the engineering ＂multi resources＂ should be optimized ,the geological ＂multi gasses＂ should be analyzed and the engineering ＂multi gasses＂ should be promoted.
