浅层气资源分布广泛,勘探开发前景广阔。针对长春岭南区块浅层气分布认识不清的问题,以埋藏较浅的泉四段储层为目的层,通过分析成藏条件,明确主控因素,研究沉积微相和断裂对气藏成藏的控制作用。结果表明:研究区气源主要来自青山口组青一段烃源岩所生成的原油伴生气;储层为河流相沉积,河道砂体厚度大、物性好,有利于浅层气富集;断裂构造和倾斜的储层砂体为浅层气提供了良好的垂向和横向运移通道;研究区具有背斜形态,被南北、北西和少量北东走向的3组断裂切割,构造圈闭条件较好;青一段烃源岩同时作为区域盖层,厚度大,断层在明水组末期停止活动,保存条件良好。沉积微相和断层是研究区浅层气成藏的主控因素,应重点寻找断层-岩性气藏,研究区东部的背斜隆起带为有利勘探区。研究成果为该区块进一步勘探指明了有利方向。

在重力流沉积区,沉积物粒度旋回难以反映基准面的变化情况,但重力流流态与类型对地形变化具有良好的响应关系。利用上述关系对重力流沉积区基准面变化的研究方法进行了探讨。研究区相对古地貌恢复结果表明,乌里雅斯太南洼腾一下亚段沉积时期控坡断层的活动性在各层序内存在明显差异,由于这种差异性导致凹陷在地形上经历了由缓至陡的变化过程,相应地,可容纳空间经历了缓慢增长、加速增长两个时期。钻井取芯、三维地震反演等资料显示,在地形与可容纳空间的变化过程中,重力流类型也随之发生变化,沉积物沉积位置亦发生迁移。因此推断重力流流态特征与沉积位置对地形以及可容纳空间变化存在一定的响应关系:断裂活动性强,可容纳空间增长速率高,地形陡,以浊流或砂质碎屑流沉积为主,沉积物主要沉积在断坡下方;断裂活动性弱,可容纳空间增长速率低,地形缓,以强黏结性碎屑流沉积为主,沉积物沉积范围广。综上认为利用重力流流态特征与类型转换可以判断地形变化趋势,进而推断基准面的变化情况。

受沉积环境的影响,在白云石形成过程中,其晶体结构与地球化学记录着相应的环境信息。本文以扬子地台晚埃迪卡拉纪灯影组杨坝剖面为例,通过系统采样研究了白云石的晶体结构和地球化学特征,明晰了基于岩石学和地球化学特征的灯影组沉积环境演化,归纳出了白云石晶体结构、地球化学特征与形成环境的耦合关系。结果表明:(1)杨坝剖面灯影组主要发育叠层石、核形石、泡沫棉石及凝块石等4种微生物白云岩和少量的晶粒、颗粒及角砾白云岩,垂向发育多期的微生物白云岩叠置韵律层,主要为局限台地潮坪相颗粒滩相。(2)地球化学分析表明,灯影组沉积演化过程为:一段主要为干旱气候、较高盐度的较浅水体,发育泥、粉晶白云岩沉积;二段下部水体加深、潮湿、低盐度,微生物白云岩最为发育;二段中上部水体总体相对较浅,湿度降低,盐度略增高;四段时水体先加深后迅速变浅,湿度逐渐降低,盐度亦逐渐增大。(3)研究区白云石晶体结构特征突显出典型的高Mg/Ca环境下流体参与形成,在干旱、高盐度的环境下,a/c值负偏,潮湿、低盐度的环境会导致晶胞参数a/c值正偏。有序度分布表明,随有序度的增加,a/c值逐渐靠近理想白云石。该结果不仅阐明准同生白云石晶体结构与形成环境关联,还揭示元古宇灯影组古海水环境特征。
