CONTROLLING FACTORS OF THE DISTRIBUTION OF CONVENTIONAL CRUDES IN NORTHERN TARIM BASIN
-
摘要: 本文根据塔北地区油气产出特点及成因机制,详细探讨了常规原油分布的控制因素,指出常规原油主要受成藏时间、油气源区、运用条件、保存条件和构造条件等因素控制,它们的共同作用和影响决定了常规原油在区域上的分布.在诸多控制因素中,尤以源区源岩热演化程度以及成藏时及其后的保存条件最为重要.Abstract: Based on the characteristics of oil/gas occurrence and its genetic mechanism,the paper detailed the controlling factors of the distribution of conventional crudes.It is suggested that conventional crudes are mainly controlled by the following factors,including time of pool-formation,oil/gas source area,conditions of migration and accumulation,and conditions of preservation and structure.Their combined function and affects will determine the regional distribution of conventional cruddes.Of these controlling factors,the thermal evolution of source rocks in source area and the conditions in pool-formation and later preservation are most important.
