摘要/Abstract

摘要： 针对注水开发油田油水井注采连通关系和见效比例等关键信息难以量化分析的问题,通过对现有注采连通关系计算方法的融合与改进,提出了一种考虑井底流压变化的多元线性回归注采连通关系分析模型,能更准确地反映油井产量变化规律,从而得到更符合生产实际的注采连通关系量化分析结果。在此基础上,将其与井组配注模型相结合,有效解决了油田配注工作中注采见效关系与见效比例确定难、人工分析工作量大等问题,实现了井组配注量的快速、准确计算。通过在新疆油田的实际应用,该模型得到了很好地验证,分析结果准确性显著提升。该研究可有效提高油田注采调配方案设计的效率与科学性,对于实现油田智能调配具有较好的促进作用,可为同类油藏的开发提供借鉴。

Abstract: In order to quantitatively characterize the injection-production connectivity, response ratio and other key information in the waterflooding oilfield, a multiple linear regression analysis model considering variable bottom-hole flowing pressure was proposed by integrating and improving the available calculation methods for injection-production connectivity. The oil production performance can be favorably characterized by this new model to obtain a quantitative and reliable analysis for the injection-production connectivity. The injection-production response and ratio were determined and the manual analysis was significantly reduced by combining with wellgroup injection allocation model. This model had been verified by a field application in Xinjiang Oilfield, and the corresponding accuracy had been significantly improved. This research could effectively improve the efficiency and scientificity of oilfield injection-production deployment program design and promote intelligent oilfield deployment and adjustment, which could provide certain reference for the development of similar reservoirs.

Key words: injection-production connectivity, injection allocation, waterflooding oilfield, multiple linear regression
