Abstract: The paper has studied the sedimentary evolution history, depositional system and sedimentary fades of deep reservoir in Liao-he Basin by using sedimentology combining with log facies and seismic facies as well as various reservoir forecasting methods to re-veal the depositional feature and sandbody spatial distribution of deep reservoir bed, analysed the reservoir characteristics of sectionSha 3 turbidite sandbody and Sha 2-Sha 4 fan-delta sandbody, and predicted favorable facies belts. The conclusion of the researchis that sublacustrine fan reservoir is of a little high porosity and general low permeability, and the petrophysical properties of sectionSha 2 fan-delta frontal reservoir is batter than that of section Sha 3 turbidity reservoir at the same depth. Finally, the sedimentrymodel and depositional feature of deep reservoir in west depression, Liaohe Basin has been summarized.
