| 摘 要： | 涠西南凹陷L1段以断块和岩性油藏为主,不同区域、不同深度油藏特征差异明显,且油水关系复杂。对L1段56个具有独立油水系统的油藏进行统计分析,结果显示L1段油藏特征具有较好的统计规律。原油物性统计表明：地下原油黏度与地面原油物性之间具有较好的相关性,由此建立的黏度预测公式,可以用于L1段地下原油黏度预测;产能研究表明：L1段产能主要受沉积微相、孔隙度、渗透率、原油黏度以及井筒温度的直接或间接影响,不同因素与产能之间的回归关系较好,可以用于指导今后L1段未测试探井的产能预测工作。

| Abstract: | Fault-block and lithologic reservoirs dominate the L1 segment in Weixi＇nan depression and have significant different reservoir characteristics and extremely complex water-oil relationships in different domain and different depth.A statistical analysis of 56 reservoirs in L1 segment with separate oil-water systems shows good statistical laws.The statistical data of oil properties shows that there is a better correlation between underground oil viscosity and ground oil properties,and based on it,an empirical formula is obtained which can be used for viscosity prediction of L1 member.Productivity research indicates that sedimentary microfacies,porosity,permeability,oil viscosity and well bore temperature can directly or indirectly affect productivity of L1 segment,and regression relations between different factors and productivity are better which can be used for predicting productivity. |
