苏北盆地高邮凹陷阜宁组二段（以下简称阜二段）是中国东部陆相页岩油勘探开发的重要层系之一，页岩油资源丰富，已成为江苏油田当前增储上产的重要接替领域。目前，该区带仍处于勘探评价阶段，全区共有8口试采井陆续投产，基于8口试采井开展生产特征与规律分析，明确了页Ⅳ亚段较页Ⅴ亚段具有见油早、含水下降快、初期产能高等动态特征，提出了采用3.0~4.0 mm油嘴进行控压生产，以实现延长自喷期及长期稳产。结合研究区地质背景与工程实践，构建了涵盖地质、工程与开发3大类共16项参数的综合评价体系，其中，地质参数包括TOC（总有机碳）含量、

（游离烃）、成熟度、压力系数以及岩相类型，工程参数包括水平段长度、加砂强度、用液强度、改造体积以及缝网复杂程度，开发参数则包括焖井时间、开井压力、稳定含水时油压、稳定含水时返排率、千吨液压降以及含水下降速度。通过统计分析与多参数相关性综合研究，明确了影响产能的关键控制要素：地质因素方面，TOC含量、压力系数与岩相类型是决定储层含油性与能量基础的核心参数；工程因素方面，用液强度与缝网复杂程度对有效改造体积与导流能力具有显著影响；开发因素方面，稳定含水时油压、稳定含水时返排率以及含水下降速度，直接反映了储层能量保持水平与压裂液置换效率，是评价开发效果的重要动态指标。研究成果识别了高邮凹陷阜二段页岩油产能的关键控制因素，深化了对该区页岩油生产规律的认识，为后续页岩油EUR（最终可采储量）预测和效益开发策略的制定提供了科学依据与实践指导。
The second member of the Funing Formation (hereinafter referred to as the Fu-2 member) in the Gaoyou Sag of the Subei Basin is one of the important strata for continental shale oil exploration and development in eastern China. It is rich in shale oil resources and has become a crucial successor field for increasing reserves and production in the Jiangsu oilfield. At present
this zone is still in the exploration and evaluation stage
with a total of 8 pilot production wells put into production successively. Based on the analysis of production characteristics and patterns of these wells
it was clarified that compared with sub-member V
sub-member IV exhibited dynamic characteristics such as earlier oil breakthrough
faster water-cut decline
and higher initial productivity. The study proposed to adopt controlled-pressure production using a 3.0-4.0 mm choke to extend the flowing period and achieve long-term stable production. By integrating the geological background and engineering practices of the research area
a comprehensive evaluation system was established
encompassing 16 parameters in three categories: geological
engineering
and development factors. Geological parameters inclu
ded total organic carbon (TOC) content
free hydrocarbon (

)
maturity
pressure coefficient
and lithofacies type. Engineering parameters include horizontal section length
sand and fluid addition intensity
stimulated reservoir volume
and fracture network complexity. Development parameters include soaking time
well-opening pressure
oil pressure at stabilized water cut
flowback rate at stabilized water cut
hydraulic pressure drop per thousand tons of fluid
and water-cut decline rate. Through statistical analysis and comprehensive multi-parameter correlation analysis
the key controlling factors affecting productivity were clarified. For geological factors
TOC content
pressure coefficient
and lithofacies type were the core parameters determining reservoir oil-bearing potential and energy foundation. For engineering factors
fluid addition intensity and fracture network complexity had a significant impact on effective stimulated reservoir volume and flow conductivity. For development factors
oil pressure at stabilized water cut
flowback rate at stabilized water cut
and water-cut decline rate directly reflected the reservoir energy maintenance capacity and fracturing fluid displacement efficiency
serving as important dynamic indicators for evaluating development effectiveness. This study identifies the key controlling factors of shale oil productivity in the Fu-2 member of the Gaoyou Sag
deepens the understanding of shale oil production patterns in this area
and provides a scientific basis and practical guidance for subsequent shale oil estimated ultimate recovery (EUR) prediction and the formulation of cost-effective development strategies.
