摘要/Abstract

摘要：

歧口凹陷沙河街组三段一亚段[Es^3（1）]页岩油勘探获得高产、稳产工业油流，证实湖相页岩油具有较大勘探潜力，并形成亿吨级规模战场，对渤海湾盆地广泛分布的沙河街组页岩油勘探具有重要借鉴意义。针对歧口凹陷沙河街组三段页岩层系沉积环境、岩性、储集性、脆性和含油性等方面展开综合研究，Es^3（1）半深湖-深湖区泥页岩孔缝发育，脆性指数高、储层敏感性差、含油气性好，具备页岩油富集的生烃、储集、含油和工程改造条件，页岩油成藏地质条件优越。纵向上，将Es^3（1）划分6个甜点段，由上至下依次为C1—C6，平面分布稳定，单段厚度分布在7~96 m，累计厚度434 m，分布面积在87.4~194.3 km²，平面甜点叠加面积为256 km²，采用体积含油率法，初步计算资源量为4.1×10⁸ t。按“老井控面、水平井提产”的原则，在Bin60-56和F38x1两口大斜度井试油获工业油流，针对C1甜点段部署水平井勘探，QY10-1-1井获得日产百吨高产油气流，Bin56-1H井自喷试采206 d后，累产油3 043.11 t，反排率为7.77%，歧口凹陷沙三段页岩油勘探取得重大突破。

Abstract:

The high and stable industrial shale oil flow from the first submember of the third member of Shahejie Formation (Es³⁽¹⁾) in Qikou Sag, Bohai Bay Basin, reveals a possible 100 million tons of oil resource in the lacustrine shale of the member and serves as a significant reference for shale oil exploration in the whole Shahejie Formation of the basin.Based on a comprehensive study of sedimentary setting, lithology, reservoir properties, brittleness and oil-bearing property of the shale series in the member, we found that the shale series are of semi-deep lake-deep lake environment and characterized by well-developed pores and fractures, high brittleness, low reservoir sensitivity and high oil-gas bearing potential.They are favorable for hydrocarbon generation and accumulation and can be easily stimulated.Longitudinally, the member can be divided into 6 sweet-spot sections, namely sections C1 to C6 downwards of 7 to 96 m thick and 434 m in total.Horizontally, the sections are distributed in areas from 87.4 to 194.3 km² with a cumulative area of 256 km².Preliminary assessment using volumetric oil content method indicates the sections have a resource of 4.1×10⁸ t.Guided by the development strategy of "using old wells to control the range of sweet spots and horizontal wells to increase production", two highly deviated wells, Wells Bin 60-56 and F38x1 were tested with industrial oil flows.Deploy horizontal well exploration for C1 sweet spot, Well QY10-1-1 was tested with 100 equivalent tons of hydrocarbon per day.Furthermore, Bin56-1H produced 3 043.11 t in total after 206 days of production, and the reverse drainage rate was 7.77%, indicating a major breakthrough in the shale oil exploration of Es³⁽¹⁾ in Qikou Sag, Bohai Bay Basin.

Key words: depositional setting, sweet spot evaluation, shale oil, the first submember of the third member of Shahejie Formation, Qikou Sag, Bohai Bay Basin
