建立了井组模型 ,研究了布井方式和井距对底水潜山油藏开发过程中油井产水的影响 ;分析了不同注水方式、采液强度、注水和调堵时间情况下油藏开发动态和出水规律 ;综合分析了单井和井组模型的生产特征 ,导出裂缝型潜山油藏含水率上升曲线的函数表达式 ,在统计的基础上 ,利用多元回归分别给出了单井和井组含水率上升曲线系数与影响因素的关系式 ,该式包括了地质及工艺参数 ,并将裂缝和基质的参数分开 ,计算结果将更为准确可靠 ,同时为双重介质油藏含水率预测及控水措施的选择实施提供了分析依据
The well group model was established to study the effect of well layout and well spacing on well production in wellbore buried hill reservoirs. The reservoir development under different waterflooding patterns, liquid production strength, waterflooding and plugging time was analyzed Dynamic and law of water discharge. Based on the analysis of the production characteristics of single-well and well group model and the derivation of the function of the rising curve of water cut in buried-hill fractured reservoir, based on the statistics, The relationship between the coefficient of rising of water cut in well group and the influencing factors, which includes the geological and technological parameters, and separates the crack and matrix parameters, the calculation result will be more accurate and reliable. Water control measures to provide the basis for the implementation of the choice
