近期,国家规划在四川盆地建设天然气千亿立方米产能基地。为了推动和保障该产能基地的顺利建设,在回顾四川盆地天然气开发历程的基础上,提炼了各发展阶段的特点,论述了天然气开发领域基础理论和关键技术进展,展望了天然气开发关键技术发展方向。研究结果表明:①四川盆地现代天然气工业经历了探索起步期、储产缓增期、快速增长期、多源全兴期四个阶段;②钻井、储层改造技术主要体现在深井超深井钻井、水平井分段多簇密切割压裂和碳酸盐岩体积酸压,气藏工程主要体现在碳酸盐岩渗流模型表征、复杂气藏流体相态分析、压裂—生产一体化数值模拟、复杂气藏气井试井方面,排水采气技术主要体现在井筒积液规律诊断和组合式排采工艺,高含硫气藏安全生产在深井超深井安全高效建井和井下、地面设施腐蚀控制技术等方面取得长足进步;③未来发展主要面向碳酸盐岩气、致密砂岩气、页岩气和煤层气,深化复杂多重介质传质理论研究,着力提升钻完井、储层改造、排水采气等关键技术的信息化、智能化水平。结论认为,梳理的关键技术和发展方向将加快四川盆地天然气工业发展,促进该盆地尽快建成千亿立方米天然气生产基地。
According to the national plan,a natural gas production base of 100 billion cubic meters will be built in the Sichuan Basin.In order to promote and ensure the smooth construction of this base,this paper reviews the natural gas development history in the Sichuan Basin and summarizes the characteristics of each development stage.In addition,the progress in basic theories and key technologies in the field of natural gas development is discussed,and the development direction of the key development technologies is predicted.And the following research results are obtained.First,the modern natural gas industry in the Sichuan Basin experiences four stages,i.e.,initial exploration period,slow reserve and production increase period,rapid growth period and multi-source booming period.Second,great progress has been made in terms of drilling and reservoir stimulation technologies,gas reservoir engineering,drainage and gas recovery technologies and safe production of high-sulfur gas reservoirs.The main progress in drilling and reservoir stimulation technologies include drilling of deep and ultra-deep wells,staged multi-cluster dense fracturing of horizontal wells and volumetric acid fracturing of carbonate rocks;the progress in gas reservoir engineering is mainly reflected in the characterization of carbonate seepage models,fluid phase behavior analysis of complex gas reservoirs,numerical simulation of fracturing–production integration,and gas well test of complex gas reservoirs;the progresses in drainage and gas recovery technologies include diagnosis of wellbore liquid loading laws and the combined production technology;and the main progresses in the safe production of high-sulfur gas reservoirs are reflected in the safe and efficient construction technology of deep and ultra-deep wells and the corrosion control technology of downhole and surface facilities.Third,in the future,the development shall focus on carbonate gas,tight sandstone gas,shale gas and coalbed methane,and it is necessary to enhance theoretical research on complex multi-medium mass transfer and strive to improve the informatization and intellectualization level of key technologies such as well drilling and completion,reservoir stimulation and drainage and gas recovery.In conclusion,the key technologies and development direction analyzed in this paper will speed up the development of natural gas industry in the Sichuan Basin and promote the construction of the natural gas production base of 100 billion cubic meters as soon as possible.
