四川盆地东部盆缘JY1井龙马溪组页岩测试获得高产工业气流,经过长时间试采,压力、产量稳定,实现了南方复杂构造、高演化程度海相页岩气的战略突破。通过对JY1井构造、岩性与龙马溪组TOC、热演化程度及矿物含量特征的分析,结合区域地质资料,得到如下启示:①与北美地区不同,在多期构造演化和抬升剥蚀背景下,构造与保存条件是页岩气富集成藏的首要条件;②龙马溪组只有下部优质烃源岩才起到滑脱作用,多期层滑和构造作用形成的网状裂缝是页岩气富集高产的关键;③上奥陶统灰岩为龙马溪组页岩气的形成起到了良好的封隔作用;④与常规气藏不同,断裂和抬升的破坏作用对优质页岩层系的影响相对较弱,对南方广大地区页岩气的勘探具有示范意义。

Well JY1 is located in the east of Sichuan Basin.Commercial gas with high production has been tested and stable pressure and production has been maintained for long time by testing production in Longmaxi shale in well JYl.It marks the strategy breakthrough in marine shale gas exploration in complicated structural area at high thermal stage in southern China.According to the analyses of the structure,formation combination,lithology, TOC,RO,and mineral contents,combined with regional geological data,following conclusions have been obtained:(1)Structural and preservation conditions are the most important for shale gas to accumulate under the background of multiple structural evolutions and uplifts and erosions,which is different from that in North America;(2)Only the qualitative hydrocarbon rocks can play the role of detachment,and net-like fractures by multiple detachments and tectonic movements are key factors for shale gas abundance and high production;(3)The Upper Ordovician limestones take the role of sealing for the abundant shale gas in Longmaxi Formation;(4)Faults and uplifts made a few destructions to shale gas reservoirs.All implications above will have an exemplary meaning for shale gas exploration in southern China.
