摘要:

基于束鹿凹陷高分辨率三维地震连片和新钻井资料,制定了"井震结合、地震追踪、沉降中心、确定层序"的研究思路,运用钻井、测井、地震新技术新方法,将束鹿凹陷沙河街组三段下亚段精细划分为5个三级层序和15个准层序组,确定了泥灰岩、砾岩有利发育部位,明确了泥灰岩、砾岩储层在各层序中的空间配置关系,并对"源-储一体"型泥灰岩油气藏和"源-储共生"型砾岩油气藏2种致密油油气藏类型和资源潜力进行了分析,从而指出油气勘探有利方向。

关键词: 束鹿凹陷, 沙河街组三段下亚段, 泥灰岩-砾岩, 高精度层序, 致密油油气藏类型

Abstract:

Based on high-resolution 3D seismic data and new drilling data, a research approach of well-seismic combination, seismic trace, location of subsidence center, and sequence identification was proposed. Through new methods of drilling and well logging, as well as new seismic technologies, the lower part of Member 3 of Shahejie Formation in Shulu sag, was precisely divided into five third-order sequences and 15 parasequence sets. Then favorable development areas of calcilutite and rudstone were determined, and spatial configuration relationship of calcilutite and rudstone reservoirs in each sequence were defined. Meanwhile, an analysis was carried out on reservoir types and resource potential of two kinds of tight oil and gas reservoirs (source-reservoir-integrated calcilutite reservoir and source-reservoir-coexisting rudstone reservoir), pointing out favorable direction of oil and gas exploration in Shulu sag.

Key words: Shulu sag, lower part of Member 3 of Shahejie Formation, calcilutite and rudstone, high-resolution sequence, tight oil and gas reservoir type
