摘要
本文以地震、地质录井、测井、试油和油藏动态资料等为基础,应用层序地层学和沉积微相理论,综合研究了王庄油田沙三段油藏形成的地质背景及生、运、储的基本关系和储层沉积规律,揭示了王庄油田沙一段和沙三段间不整合面对油气聚集的控制作用。通过物理模拟研究了温度对储层流体流动特征的影响和储层敏感性特征,建立了反映储层敏感特征的稠油注蒸汽热采数学模型,应用有限差分方法建立了计算数值模型和研发了计算软件,并应用于王庄郑411区块蒸汽吞吐开采指标的计算和预测,为同类型油藏开发提供了研究方法和理论依据。
Based on the data of seism, geological logging, well logging, well testing, and reservoir properties, etc., applying sequence stratigraphy and sedimentary microfacies theories, this paper comprehensively studied the geological background conditions of the forming of the ES3 reservoir in Wangzhuang Oilfield, the essential correlation between the oil source generating and migating and reserving of this Es3 reservoir, and its sedimentary law. Discovered the controlling effect of the unconformity surface between Es1 and Es3 in Wangzhuang Oilfield on the oil and gas gathering. By means of physical simulation, studied the effect of temperature on the flow behavior of reservoir fluids, and researched for the reservoir sensitivity characteristics. Established the heavy oil steam injection thermal recovery numerical models with featuring the reservoir sensitivity. Applying finite difference method, established numerical models, and developed the software. Applying the software to the specification calculations and predictions of the steam injection production for Zheng 411 Block in Wangzhuang Oilfield, provided a theoretical and practicable method to the same types of reservoir developments.
