摘要: 羌塘盆地侏罗系白云岩是该盆地重要的油气储集层。侏罗系碳酸盐岩在沉积期后经历了白云岩化作用、溶蚀作用和破裂作用等多种成岩作用。羌塘盆地白云岩的成因与毛细管浓缩作用和混合水白云化作用有关。

Abstract: The Jurassic dolostones occur as important hydrocarbon reservoirs in the Qiangtang Basin on the Qinghai-Xizang Plateau,and have undergone a complex diagenetic history including dolomitization,dissolution and fracturing.The genetic mechanism includes capillary condensation and mixed water dolomitization,of which the latter one predominates in the study area.
