Research on hydrocarbon abundance conditions in nearshore sublacustrine fan in Western sag of Liaohe Basin——take Rehetai Formation in Xing-Bei area as an example;

Oil-oil meticulous correlation research shows that there exist both immature and mature oils in Oulituozi area of the Liaohe Basin,and the maturity level of these oils is generally lower than those in the other areas of the East Sag.

According to analysis of formation water and crude oil at the west Jinganpu of Damintun Sag in the Liaohe Basin,type NaHCO_3 formation water on the top of the burial hills in the studied area is dominative,type CaCl_2 appear in local area.

In order to understand the control of hydrogeological conditions on accumulation of coalbed methane in low rank coal,a comparison study is carried out between the Powder River basin in America and the Juggar basin in China.
