柯克亚凝析油气田所产原油为挥发性原油，气为凝析气。油气性质在地下状态差别小，用测井资料对具气顶的油环确定油气界面及划分油气层非常困难。可利用挥发性原油与凝析气的特殊性，油层与气层在气测及荧光录井中的显著差别，准确确定油气界面及划分油气层。
The crude oil produced in the Kirkho condensate field is a volatile crude oil and the gas is condensate gas. The difference of oil and gas properties in underground state is very small. It is very difficult to determine the oil-gas interface and the division of oil and gas by the well logging data on the gas ring with gas cap. The particularities of volatile crude oil and condensate gas can be utilized. Significant differences between gas reservoirs and gas reservoirs in gas measurement and fluorescence logging can be utilized to accurately determine the interface between oil and gas and to divide the hydrocarbon reservoirs.
