根据储集层中原油分布推测储集层产液特征,是勘探开发工作的关键。由于非均质储集层中原油分布受制于渗透率级差、注油速率、充注模式和充注量等因素,导致原油在其中的分布状态复杂多样。储集层产液特征与原油在储集层中的分布密切相关。明晰影响非均质储集层中原油分布的因素及与产液特征的关系,同时注意润湿性、孔隙结构和油质条件对储集层产液的影响,才能较为准确地预测储集层产液特征,为勘探开发方案的制定提供有利依据。
It is the key of exploration and development to infer reservoir fluid characteristics according to the distribution of crude oil in reservoirs. As the distribution of crude oil in heterogeneous reservoirs is subject to factors such as permeability gradient, oil injection rate, filling mode and charging amount, the distribution of crude oil therein is complex and diverse. Reservoir fluid characteristics are closely related to the distribution of crude oil in the reservoir. Clearly affect the distribution of crude oil in heterogeneous reservoirs factors and the relationship with the characteristics of liquid production, while paying attention to wetting, pore structure and oil conditions on the reservoir fluid production in order to more accurately predict the reservoir Liquid production characteristics for the development of exploration and development programs to provide a favorable basis.
