摘要:

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。

Abstract:

Solution pores are the main reservoir space of Fuyu reservoir in Fuyu-Xinli region. They are mainly particle solution pores, filler solution pores and particle-filler solution pores. The acid components that resulted in the solution pores were provided by organic matter which resulted from kerogen deacidify,thermo-catalysis and thermo-transformation in middle diagenesis from overlain dark mudstone and shale of the first member of the Qingshankou Formation.The formation of the pores is not only effected by original texture and composi-tion of sand beds, but also closely related to rigional structure position (such as syngenetic structure apex), faults and fractures. A stable and appropriate tectonic condition may be particularly favourable for long term seepage and complement of acid water, and may result in various kinds of solution pores,especially feldspar pores.
