根据中国南部海上救助运动复杂的泥土页岩之间保存条件好坏的情况领先的岩页,是机体能否良好运行的一个重要因素。本文通过对四川盆地缘海相页岩气的研究,分析页岩机体具有作为成果、关闭率等方面纵横向2~8倍的差异,向侧面页扩散的岩天然气基本丧失通道,不再出现保存条件恶化,断层的切割也会加速页岩气下降。同时为了分析岩层页面的主控保存条件和岩层研究指标判别得出因素:(1)结构改造强度:岩页的主控保存条件运用层结构样式因素,连续层盖子、缓幅度、背斜背景的结构有利于岩页天然气丢失下降;(2)保存在断层处的安全发育,断层封闭性更好或断层下盘的断块区相对远离露头区或腔隙,页岩气可以有效保存;(3)地区流域面积内,除了缺乏剥蚀区和邻近地层线区的页岩气保存不好之外其他的都可为更好的保存条件。
The leading rock pages, based on the conditions for the preservation of complex shales in the maritime rescue movement in southern China, are an important factor in the good functioning of the body. Based on the study of marginal marine shale gas in the Sichuan Basin, this paper analyzes that the shale body has the difference of 2 ~ 8 times in horizontal and vertical directions as the result and the closing rate. The rock natural gas diffused to the lateral page basically loses the channel and no longer appears to be saved As conditions worsen, fault cuts can also accelerate shale gas declines. At the same time, in order to analyze the main controlling conditions of rock strata and the distinguishing factors of strata research index: (1) The intensity of structural reform: The main controlling condition of rock strata is to use stratified structural style factor, continuous layer cover, slow amplitude, anticline background The structure is favorable for the loss and loss of natural gas in the lithosphere. (2) The well-developed faults with better fault sealing and fault blockage preserved in the faults are relatively far away from outcrops or cavities and the shale gas can be effectively preserved. ) Within the drainage area of the area, except for the poor preservation of shale gas in areas lacking denuded areas and adjacent stratigraphic strata, better storage conditions may be provided.
