溶蚀孔隙是本区扶余油层的主要储集空间,主要有颗粒溶孔、填隙物溶孔和颗粒-填隙物溶孔三类。溶孔形成既受粒度等砂层原始结构和成分的影响,又与它在成岩中所处局部构造部位(如同生构造高点等)和断层、裂隙发育程度密切相关。特别是一个稳定、适当的构造条件,可以使各种来源的酸性水长期渗流、补充。造成类型多样的溶孔,尤以长石溶孔更具特色。
The dissolution pores are the main storage space for the Fuyu oil layer in this area. There are mainly three kinds of dissolved pores, such as particle dissolved pores, interstitial dissolved pores and particle-interstitial dissolved pores. The formation of dissolved pores is affected not only by the original structure and composition of sand layers such as grain size, but also by the local structural parts (such as the synoptic structures) and the development of faults and fractures in diagenesis. In particular, a stable and appropriate construction conditions can make acidic water from a variety of sources long-term seepage, supplement. Cause a wide variety of dissolved pores, especially feldspar dissolved pores more features.
