摘要/Abstract

摘要：

皖南泾县地区广泛出露下三叠统殷坑组,但其油气勘探程度相对滞后。通过野外露头调查、地质调查井岩心资料、测试分析数据,综合探讨皖南地区殷坑组沉积特征、生烃条件和储层条件。基于“无人机立体摄影”采集技术,对剖面露头进行创新的数字化调查,可提取构造和沉积信息。结合人工地质考察与剖面数字化,皖南地区泾县晏公堂殷坑组可划分为16小层;殷坑组岩性组合总体上为灰色泥粉晶灰岩、砾屑灰岩、角砾灰岩,夹黑色、黑灰色泥岩。殷坑组泥岩累计厚度43.8 m,TOC(总有机碳含量）为0.38 %~2.21 %,镜质体反射率为0.95 %~1.21 %,殷坑组页岩为较好烃源岩,具有巨大生烃潜力。殷坑组灰岩层段孔隙度在0.928 %~2.626 %,渗透率在（0.12~3.22）×10^-3 μm²,基质孔隙欠发育,渗透率低,但微裂缝和裂缝发育。因此,斜坡和开阔陆棚相带成为非典型“自生自储”有利沉积相带,殷坑组具有油气资源勘探潜力。

Abstract:

The oil and gas exploration of the Early Triassic Yinkeng Formation with wide distribution in the Jingxian County of the southern Anhui is relatively lagging. Based on the outcrop, well core and test analysis data, the depositional characteristics, hydrocarbon generation conditions and reservoir conditions of the Yinkeng Formation in southern Anhui are discussed. Using the “UAV stereo photography”, an innovative digital survey of the outcrop can be carried out to extract structural and sedimentary information. Combined with the artificial geology survey and the section digitization of the outcrop, the Yinkeng Formation can be divided into 16 sub-layers. The lithological of Yinkeng Formation is generally consist of gray mud limestone, conglomerate limestone and conglomerate limestone, with black and black gray mudstone. The cumulative thickness of the Yinkeng Formation is 43.8 meters with the TOC content ranging from 0.38 % to 2.21 % and the vitrinite reflectance ranging from 0.95 % to 1.21 %, indicating that the shales of the Yinkeng Formation is good source rocks and has a hydrocarbon potential. The porosity and permeability of limestones in the Yinkeng Formation range from 0.928 % to 2.626 %, and 0.12×10^-3 μm² to 3.22×10^-3 μm², respectively. The limestone intervals have under-developed matrix pores and low permeability, but have developed micro-fractures. Therefore, slopes and open shelf are favorable sedimentary facies with “self-generation and self-storage” petroleum system, and the Yinkeng Formation has large hydrocarbon potential.

Key words: sedimentary facies, hydrocarbon potential, Yinkeng Formation, southern Anhui, Jingxian County
