摘要
提出了原油物性模拟的修正模型 ,其结果与PVT曲线具有良好的相关性。给出了电潜泵内流体温升及井筒中流体温度梯度的计算方法。通过引入井眼轨迹的描述与计算技术 ,成功地解决了弯曲井段的多相流计算问题 ,从而可以计算出任意井眼形状中的参数分布规律。在此基础上 ,借助于毛细管、动液面或泵特性测试资料 ,实现了对电潜泵井生产动态的模拟和分析 。
A modified model to simulate the crude properties is presented,and its results correlate well to the PVT curve.The calculation methods for the fluid temperature increment in the submersible electric pump and the temperature gradient along the well bore are also developed.By introducing the techniques for describing and calculating the trajectory of a well bore to the multiphase flow calculation,the problems appeared in calculation for the curved well bore sections were successfully solved.As a result,the distribution of every parameter along the well bore with any shape can be found.On the basis of these,the simulation and analysis on production performance for a well with submersible electric pump were achieved by means of the test data from capillary,producing fluid level and pump characteristic curves.This method has brought a good effect when used in oil fields.
