摘要

摘要: 兴仁堡凹陷位于六盘山盆地的东南部，为中生代盆地，勘探程度较低，处于早期评价阶段。基于该区钻井、露头取心、二维地震和重磁等综合资料，对凹陷内烃源岩有机质丰度、类型、成熟度等地化参数及成藏有利因素进行分析评价。凹陷内三叠系延长组烃源岩为中等烃源岩，有机质类型为Ⅱ-Ⅲ型，成熟度为低熟-成熟，具有一定的勘探潜力，下一步应以自生自储油藏勘探为主；侏罗系直罗组烃源岩是较好烃源岩，有机质类型为Ⅰ-Ⅱ型，成熟度属低熟-成熟，是下一步构造、岩性勘探的物质基础和重点方向，应加以重视。

Abstract: The Xingrenpu Sag is located in the southeast of Liupanshan Basin, which is a Mesozoic basin in the early evaluation stage with only limited exploration. The geochemical parameters of hydrocarbon source rocks such as organic matter abundance, type and maturity and the favorable factors for reservoir formation were discussed based on drilling, outcrop core, two-dimensional earthquake and magnet data. The source rocks of the Triassic Yanchang Formation in the sag are medium source rocks, the organic matter belongs to type Ⅱ-Ⅲ, and the maturity is low-mature to mature, which show a certain exploration potential. The exploration of self-generated and self-reservoired resources should be focused on in the future. The Jurassic Zhiluo Formation source rocks are good hydrocarbon source rocks with typeⅠ-Ⅱ organic matter, and the maturity is low-mature to mature, providing exploration targets for structural and lithologic traps.
