Abstract: The planar fluid distribution of Cardomifero us v olcani c reservoi rs i n the Shixi Oilfi eld show s a re-markable trend i. e crude oil becomes heavier from south to north and its properties are not contro liedby the structure. There is difference between the formation water in the eastern and western parts. Theformation water has a lower salinity in the western part with gradient of ion concentration increasingform south to north while ion has a higher salinity in the east with gradient of ion concentration increas-ing from west to south. Asynthetic study indicated that the migration or injection direction of formationwater and crude oils is from south to noth and faults in the central part of reservoirs separated the dstri-bution of formation water and faults into two parts, and then affected oil and gas productivity.
