| 摘 要： | 通过井下长时压力计监视油藏压力的变化是目前油田后期开采监测油藏变化的一种新方法,其测试资料的解释成为当前试井解释研究的热点,解释结果对油藏描述、动态分析以及生产动态管理都具有重要的指导意义。根据长时测试过程的测试周期长的特点,建立长时压力计变流量条件下的数学模型,利用数值Laplace变换算法快速计算压力响应,应用非线性优化技术进行全压力史自动拟合,能够有效地确定油藏参数,并已成功地应用于辽河油田的热采监测过程。

| Abstract: | A new method of monitoring reservoir in oil field developing evening is by use of permanent downhole gauges(PDG) to measure the variance of pressure. The result of which will play an important role in characteristic of PDG long test time, the mathematics model of PDG has been established at variance rate condition.The algorithms of numerical Laplace transform are used to calculate pressure response quickly,and the full pressure history was matched automatically by nonlinear optimization to estimate reservoi... |
