喇嘛甸油田驱油效果评价岩心实验研究
|
摘要
针对喇嘛甸油田经过长期水驱后,储层的孔隙度、渗透率、孔喉特征及岩石的润湿性、敏感性变化的实际情况,通过对密闭取心资料分析、检查井统计资料分析、电镜扫描结果分析及室内实验结果,研究了各类储层的微观孔隙特征变化规律和岩心润湿性、敏感性的变化规律。
通过室内驱油实验,研究了各类油层水驱、化学驱的驱油效果。在此基础上,研究了各类油层注入倍数与含水率的关系,确定了合理的注入速度、聚合物注入浓度、三元段塞组合方式。通过现场资料,统计了喇嘛甸油田的水驱波及系数,进一步由室内实验进行了聚合物驱油波及系数的研究。
本文把岩心实验分析结果和现场统计结果进行综合对比分析,从理论上分析影响水驱、化学驱油藏开发效果的各种因素,并结合大量的实际资料,搞清目前喇嘛甸油田的开发状况及开发指标规律,为喇嘛甸油田的合理开发提供准确可靠的理论依据。
The regularity for change of microcosmic pore characteristic of all kinds of reservoirs and wettability and sensibility of core are researched through analyzing the data of sealing core, the statistical data of inspection wells, the results of scanning electron microscope and the results of experiments indoor for the actual situation that the changes of porosity, permeability, pore throat characteristics of reservoir and wettability and sensibility of core occur after long period of water flooding.
The flooding efficiency of water flooding and chemical flooding for all kinds of reservoirs is studied through the experiments of flooding indoor. On that basis, the relationship between the multiplier of injected water and water cut is researched, and the reasonable injection velocity, polymer concentration and slug composition are determined. The water flooding sweep efficiency for Lamadian oil field is collected through onsite data, and further research is carried out by experiments indoor for polymer flooding sweep efficiency.
In this paper, the analyzing results of core experiments and the statistical results onsite are carried out comparative analysis to analyze all kinds of factors that influence the development efficiency of water flooding and chemical flooding in theory. Now the development condition and the regularity of development indexes in Lamadian oil field are clear through combining a lot of actual data. All these things provide a reliable theoretical foundation for reasonable development for Lamadian oil field.
