水驱开发效果评价新方法及其矿场应用

为明确注水开发效果的影响因素，有效指导油田综合调整，提出应用图版评价开发效果的新思路。依据谢尔卡乔夫公式和Arps产量递减方程，考虑储层物性、流体性质、相渗特征、井网密度、采出程度等因素，建立了一种开发效果评价图版。在海拉尔盆地A区块的应用实例表明，该图版评价结果与实际油田开发特征相匹配，对不同类别区块的开发规律及注水矛盾区分明显。在开发效果评价研究的基础上，制定了A区块综合调整措施，取得了良好的实施效果。该方法简单实用，具有一定的推广价值。

New method for evaluating water flooding development effect and its oil field application

In order to clarify the influencing factors of waterflooding development effect and effectively guide the comprehensive adjustment of oilfield,a new approach of using chart to evaluate development effect was put forward. Based on Sherkachev formula and Arps production decline equation,considering reservoir properties, fluid properties,relative permeability characteristics,well spacing density and recovery degree,a water flooding development effect evaluation chart was established. The application in block A shows that the evaluation results of this chart is consistent with the actual oilfield development characteristics. The development law and water injection contradiction of different blocks can be distinguished obviously. Based on the evaluation of water flooding development effect,the comprehensive adjustment measures of block A were put forward,and it had a good implementation effect. This method is simple and practical,and has certain popularization value.
