文昌油田产量预测问题及解决方法研究
|
摘要
产量预测是油田开发过程中一项重要的研究工作,该工作不仅影响油田开发方案的制定,而且也是公司产量指标的主要判断依据。油田产量预测方法有多种,如产量递减法、水驱曲线法、数值模拟法等。此文通过借用数值模拟法中定液量拟合含油率的思路,预测含油率随时间的分布规律,结合产液量规划数据计算得到产油量随时间的关系曲线。矿场实践证明该方法可有效提高产量预测精度。
Production prediction is an important research work in oilfield development,which not only affects the formulation of oilfield development plan,but also is the main judgment basis of the company's production index. There are many methods for predicting oilfield production,such as production decline curve method,water drive curve method,and numerical simulation method. In this paper,the decline curve of oil content with time can be predicted by using the way of fitting the oil content with numerical simulation,then the relation curve between oil production and time can be calculated based on the data of liquid production planning.Field practice proves that this method can effectively improve the yield prediction accuracy.
