摘要/Abstract

摘要： 针对松辽盆地三肇凹陷葡萄花油层油气富集主控因素不清的问题,运用测试资料和地震数据综合分析了油气成藏主控因素,并建立了油气富集模式,为油气勘探提供理论依据。研究结果表明:沉积微相控制了优质储层展布;油源断层和砂体组成优势输导通道;三肇凹陷发育了构造-岩性和岩性圈闭两大类构造,细分为鼻状构造-岩性圈闭、断层-岩性圈闭、低幅背斜-岩性圈闭、砂岩上倾尖灭圈闭4个小类,圈闭控制了研究区的油水分布,形成了沉积微相控储、油源断层和砂体控运移和圈闭控富集的油气成藏模式。该研究可为松辽盆地三肇凹陷葡萄花油层的勘探提供有效指导。

Abstract: To address the problem that the main controlling factors of hydrocarbon enrichment in the Putaohua reservoir in the Sanzhao Sag of the Songliao Basin are unclear, the main controlling factors of hydrocarbon accumulation are comprehensively analyzed by using test data and seismic data, and a hydrocarbon enrichment model is established to provide a theoretical basis for hydrocarbon exploration. The results of the study show that the sedimentary microfacies controls the distribution of favorable reservoirs; the oil source faults and sand bodies form the dominant transportation channels; two major types of tectonic-lithologic traps and lithologic traps have been developed in the Sanzhao Sag, which are subdivided into four subcategories: nose-like tectonic-lithologic traps, fault-lithologic traps, low-amplitude anticline-lithologic traps, and single sand body up-dip thin-out traps, and these facilitated traps control the distribution of oil and water in the study area, forming a hydrocarbon accumulation model of reservoir control by sedimentary microfacies, transport control by oil source faults and sand bodies, and enrichment control by traps. This study can provide effective theoretical guidance for the exploration of the Putaohua reservoir in the Sanzhao Sag of the Songliao Basin.

Key words: main controlling factors of hydrocarbon accumulation, accumulation mode, transportation system, Putaohua Reservoir, Sanzhao Sag, Songliao Basin
