摘要:

渤海湾盆地渤南地区明下段窄条带状油藏水流优势通道类型多、识别难、治理难,严重影响注水开发效果。根据112个示踪剂测试样本产出曲线形态特征,将水流优势通道划分为4级,在研究每个级别储层物性参数及生产动态响应特征的基础上,创新建立了水流优势通道判别参数体系,进而定量表征了优势通道的发育程度;综合运用统计和灰色关联分析等方法,定量确定了影响水流优势通道的主控因素,提出了针对4级优势通道的分类治理对策。结果表明,油田经过长期的注水开发,三级优势通道占比最高,占总数的59%;三级优势通道的解释渗透率平均值为7 037 mD,孔喉半径平均值为16.0 μm;影响水流优势通道的主要因素是生产压差、河道宽度,在注采井距的设计和动态调整过程中,应充分考虑这两个因素。研究结果为窄条带状油藏控水措施的制定及调剖、调驱全周期优化和评价提供了科学依据,现场应用取得了较好的降水增油效果。

Abstract:

The narrow strip-shaped reservoirs in the lower member of Minghuazhen Formation in the Bonan area of the Bohai Bay Basin are characterized by diverse types of dominant flow channels,which are difficult to identify and control,severely impairing the waterflooding development effect.Based on the morphological characteristics of production curves from 112 tracer test samples,dominant flow channels were classified into four levels.By investigating the reservoir physical property parameters and production dynamic response characteristics of each level,an innovative discrimination parameter system for dominant flow channels was established,and the development degree of preferential channels was quantitatively characterized.Using a combination of statistical methods and grey relational analysis,the main controlling factors affecting dominant flow channels were quantitatively determined,and classified control countermeasures for the four levels of preferential channels were proposed.The results show that after long-term water injection development,Level Ⅲ dominant flow channels accounts for the highest proportion,reaching 59% of the total.The average interpreted permeability is 7 037 mD,and the average radius of pore roar is 16.0 μm.The main factors affecting dominant flow channels are production pressure difference and channel width,which should be carefully considered in the design and dynamic adjustment of injection-production well spacing.The research findings provide a scientific basis for formulating water control measures and conducting full-cycle optimization and evaluation of profile control and profile modification and flooding in narrow strip-shaped reservoirs.Field applications have achieved favorable effects of water cut reduction and oil production increase.
