四川盆地黑色页岩层系多、页岩气资源丰富,是迄今为止中国主要的页岩气勘探开发盆地。为了给今后四川盆地乃至整个中国南方地区页岩气勘探开发提供指导和参考,以该盆地上奥陶统五峰组—下志留统龙马溪组页岩气勘探开发实践为对象,总结了其发展阶段与进展,明确了页岩气富集成藏的有利条件,梳理了制约页岩气发展的理论与技术挑战,进而探讨了未来的勘探开发前景。研究结果表明:(1)深水陆棚相形成高富含有机质页岩且连续段厚度大、品质好,复背(向)斜宽缓区构造相对稳定是该盆地五峰组—龙马溪组页岩气持续聚集的有利条件,保存条件是页岩气富集的关键因素,页理(纹理)、微裂缝发育是页岩气高产的重要因素,超压是页岩气高产的重要条件;(2)制约该盆地五峰组—龙马溪组页岩气工业化发展的技术瓶颈,主要包括富有机质页岩沉积相与沉积模式,页岩储层成岩过程与评价体系,页岩气形成与聚集机理,页岩气层地球物理识别与预测,资源动用率低、不确定性大,3500 m以深页岩气勘探开发技术尚未突破。结论认为,四川盆地五峰组—龙马溪组仍是今后相当长一段时间内中国页岩气勘探开发的重点层系。

对带多面体约束的非光滑复合函数问题的求解进行了研究。针对非光滑复合函数问题,首先,构造光滑函数来逼近非光滑目标函数,通过求解光滑近似问题来达到求解原问题的目的。在此基础上,考虑多面体约束的特殊结构,运用序列二次规划算法的思想,利用有效集策略,通过逐次求解一系列仅含等式约束的二次规划问题来逼近搜索方向的最优解,再通过线搜索求得步长,进而得到下一步的迭代点。最后,从理论上证明了算法的全局收敛性,并进行了初步的数值实验。将该算法与光滑序列投影收缩算法作对比,结果表明,该算法在迭代次数和计算时间上都有一定的优势。
