鄂西渝东区石炭系黄龙组储集层评价与预测及成藏作用研究
|
摘要
鄂西渝东区位于四川盆地东南缘，齐岳山背斜带以西，长江以东，面积约9500km~2。本文研究主要通过地层层序、沉积相、成岩作用和储集条件等方面对该区石炭系黄龙组碳酸盐岩储层进行评价和预测，并且从该区7个重点构造的钻探成果出发进行烃源岩、盖层和圈闭保存条件等成藏条件的分析与评价，分别得出以下结论：①工区最有利的储层是石炭系白云岩残厚＞20m的分布区，位于轿1井—茨竹1井—马鞍1井—石柱县城以西地区；较有利的储层是石炭系白云岩残厚10～20m的分布区，位于Ⅰ级区以东及以西的洋渡1、2井外围；不利的储层是白云岩＜10m及石炭系黄龙组灰岩的分布区，位于工区西南部和东部地区。②成藏的有利区位于石柱复向斜内和方西区块；成藏的较有利区位于茨竹垭——龙驹坝地区；成藏不利区位于齐岳山及其西翼、方斗山等地。
Western Hubei and Eastern Chongqing Region lays southeast border of Sichuan Basin with its area about 9500 km2. Qiyue Mountain anticlinal structure is on the east of it and Changjiang River on the west of it. After synthetically studying on effects of strata sequence, sedimentary fades, diagenesis function and storing-upping condition the author evaluates and forecasts carbonate reservoir of Hanglong Formation of Carboniferous in work area. And the author analyses and evaluates hydrocarbon source rock, caprock and trap reserving condition of work area on the base of drilling achievements of 7 emphases structure hi work area. Therefore the author draws two conclusion as follow: (1)the most favorable reservoir of the work area is the spreading region of dolomite rock of Carboniferous whose remaining thickness is greater than 20m with the region from Jiao 1 well-Cizhu 1 well-Maan 1 well to west of Shizhu County seat. The secondary favorable reservoir of it is the spreading region of dolomite rock with the remaining thickness greater than 10m but less than 20m which is eastern and western region of the most favorable region and the off-lying of Yangdu 1 well and Yangdu 2 well. The adverse reservoir of work area is the spreading region of limestone and dolomite rock with the remaining thickness less than 10m which is in- the southwest and east of the work area. (2)The most favorable region of gas formation lays inside of the Shizhu synclinore and in the west of Fangdou Mountain block. The secondary favorable region is from Zichuya region to Longjuba region. The adverse region lays Qiyue Mountain Structure including west of it and Fangdou Mountain Structure.
