岩性变化 meaning in Chinese
lithological change
Examples
- Mechanical changes and sometimes lithological changes, take place in the rocks on either side of the fault .
断层两边岩层发生机械力学变化，有时也有岩性变化。 - On the basis of sequence frame , combined with growing characteristics and lithologic feature of beir depression , stratigraphic sedimentary pattern of different evolution stage are obtained
在建立层序地层格架的基础上，结合盆地的演化特征及岩性变化，做出了本区不同演化阶段的沉积模式图。 - There are various reservoir structure types of the insert salt layers non - sandstone reservoirs in jiangban oil region , mainly including porous type , porous - fracture type and fracture type , and high mineral contents of clay
摘要江汉油区盐间非砂岩储层结构类型多，主要有孔隙型、孔隙裂缝型和裂缝型；粘土矿物含量较高；这种储层主要是泥岩，含盆和白云石，裂缝发育，并且岩性变化大。 - In allusion to the characteristics of severe lithological changes , complicated mineral compositon , high carbonate content and its uneven distribution in different sections of complicated sandstone reservoirs in well xin855 of xinchang gas field , it was proposed that new acid - fracturing technique - equilibrium acid - fracturing and closed acidizing technique was used for reservoir acid reconstruction
针对新场气田新855井复杂砂岩储层岩性变化大，岩矿组成复杂，碳酸盐岩含量高，且在不同井段分布极不均匀等特点，提出采用新的酸压技术平衡酸压闭合酸化技术对该储层实施酸压改造。 - The features of these sequences arerbefore sequence i deposited during the rapid subsidence of the depression , the range of the sediment is limited . sequence ii is the first series of source and reservoir rocks of the depression . there are regional unconformity at the bottom of the sequence iii . the rock type are variety . this sequence is evaluated as good source rock , sequence iv is associated with the first section of duhongmu formation , thick mudstone at the bottom and the thick single sandston are the main rock type . this sequence are evaluated as good source rock and reservoir . sequence v associated with the second and the third section of duhongmu . which is mainly mudstone and can be regional capping rocks
层序对应于阿尔善组二段，为深色泥岩与砂砾岩不等厚互层，是本区的第一套烃源岩和储集层，可以作为本区储层。层序对应腾格尔组，此时凹陷扩张，沉积层底部具有区域性的冲刷面，岩性变化大，是较好的生油层。层序对应都红木组一段，下部泥岩发育，单砂层较厚，是主要的生油层和储层。
