Abstract:

According to the implement "Criterion of Resource Evaluation of Major Hydrocarbon Basin" implemented by the PetroChina Company Limited and the recommended system of hydrocarbon resource evaluation,the key factors influencing the resource evaluation were emphatically analyzed,in combination with the characteristics of Nanpu Sag.The geologic evaluation of basin was made by taking hydrocarbon system as the evaluation unit.Geologic evaluation of hydrocarbon distribution play was made by using geologic risk analysis.In the analysis of Gaoliu and Laoyemiao areas,the resources were calculated by using the statistical method,including the reservoir scale sequence,saturation exploration well and trap summation methods.The resources of plays were calculated with the genesis method and analogy method including the oil supply unit and analogy of area abundance. The final resources for each play were received by using Delphi forecasting method. The resources of Nanpu Sag were obtained by summing the resources of each play. Compared with the previous resource evaluation method,the combined evaluation technology of genesis,statistic and analogy methods is more objective for the resource evaluation.

Key words: geologic evaluation, oil and gas resource, reservoir scale sequence method, saturation exploration well method, area abundance analogy

摘要：

按照中国石油天然气股份公司制定的《主要含油气盆地资源评价实施规范》要求及所推荐的油气资源评价方法体系,结合南堡凹陷资料的特点,解剖了影响资源评价的关键问题.在盆地地质评价中以含油气系统为评价单元,区带地质评价主要采用了地质风险分析法.在对高柳、老爷庙两个刻度区的解剖中,资源量计算主要选用了统计法中的油藏规模序列法、饱和探井法和圈闭加和法.区带资源量计算则选用了成因法中的供油单元法、类比法中的面积丰度类比法.运用特尔菲法得出各区带的最终资源量,将各区带的资源量求和,得出南堡凹陷的资源量.由于本次资源评价中将统计法、类比法、成因法结合使用,使评价方法及结果更具客观性.
