Nanyishan shallow oil pool lies in the northern part of western Qaidamu basin,which is one of the important low permeability and low porosity reservoirs of Qinghai Oilfield Company.It is a synsedimentary anticline,which is clamped by syngenetic faults on north and south wings.The researches of lithotype and sedimentation mode are necessary for its efficient exploitation.Based on the previous research and through microscopic observations of plenty of rock slices and carbonate analyses,the paper proves that the lithology of the Nanyishan shallow oil pool formations is interlaced with pelytic and arenaceous laminae deposited in semi-deep lacustrine environment.Due to the particularity of its lithology,the paper recommended a naming system based on rock composition.
