摘要

The reservoirs in Talaha-Changjiaweizi area are mainly low and super low permeability reservoirs with commercial oil flow in certain area. To make clear the main controlling factors of reservoir forming in Talaha- Changjiaweizi area is of great significance for locating blocks with high reserves abundance. Through microscopic technology including polarized light microscope, electron microscope and fluid inclusion, combined with macrovisual study on reservoir grain size and sedimentary facies, this paper considers that Putaohua oil layer in Talaha-Changjiaweizi area belongs to typical low and super low permeability reservoir, whose controlling factors of reservoir forming is related to complex diagenesis, sediment size and sedimentary facies belt. The reservoir in studied area was reformed by denudation and had well developed secondary tation weakened the reservoir physical property in middle-later porosity.
