 针对新探区仅有地面原油常规物性分析资料、缺少表征油藏地层原始状态下的
各项数据这一现状，探寻合理、有效地确定地层原油物性参数的方法。借鉴Standing、Glaso、
Beggs、Muhammad 等人的研究思路，依据统计学、油藏工程学原理，结合辽河油田的实际资料，
充分地运用地面、地层原油物性资料进行规律性研究，建立了辽河油区曙光油田、欢喜岭油田
不同层位的原油原始气油比与体积系数经验公式。经实际资料验证，方法具有可操作性。

In order to provide technical supports for exploration and
development and reserve estimation of the oilfield, a
reasonable and effective method is explored for determination
of the physical parameters of the crude oil in situ under the
condition that in the new exploration area only conventional
PVT data of the surface oil is available in lack of various data
to characterize the reservoir initial condition. In the paper, in
view of the research results of Standing, Glaso, Beggs,
Muhammad et al, based on the statistics, reservoir engineering
theory, the empirical equation of initial GOR of the crude oil
vs. volume factor are established for different formations in
Shuguang area, Huanxiling area in Liaohe Oilfield, combined
with the actual data of Liaohe Oilfield. The empirical
equations are validated by the actual data, which shows
applicable and feasible.
