摘要
针对特高含水开发阶段传统油水相渗比与含水饱和度的半对数关系曲线不再是直线关系(出现下翘),传统油藏工程方法在特高含水及以后开发阶段适用性较差的问题,利用全过程动态相渗与传统油藏工程理论融合推导的方法,基于动态相渗的Arps产量模型对大庆长垣油田特高含水后期开发指标进行预测.结果表明:使用动态相渗Arps产量模型在特高含后水期及以后开发阶段预测指标时,误差相对较小,精度大幅提高,具有更强的适用性.研究成果为精准预测指标变化趋势、科学编制油田产量规划方案、及时调整开发对策提供了依据.
Abstract
Since the semi-logarithmic relationship between traditional oil-water relative permeability ratio and water saturation is no longer linear relationship in ultra-high water cut development stage but shows downwarping,and tradi-tional reservoir engineering methods have poor applicability in ultra-high water cut and subsequent development stag-es,fusion derivation of whole-process dynamic relative permeability and traditional reservoir engineering theory is used to predict development indexes in late ultra-high water cut stage of Daqing placanticline oilfield by Arps produc-tion model based on dynamic relative permeability.The results show that dynamic relative permeability Arps produc-tion model predicting indexes in ultra-high water cut and subsequent development stages has relatively small error and significantly improved accuracy with much applicability.The research provides basis for accurately predicting in-dexes variation trend,scientifically planning oilfield production schemes and timely adjusting development strategies.
