curve generators

The result will be used to compare with the actual production curve for curve fitting and establishment of reasonable estimating model, which will be used to predict the future output of water and metha.

本文根据煤层气井的储层参数和水文地质数据,通过计算排采在煤层中形成的压力降, 再结合兰氏方程、临界解吸压力等参数,进一步计算出煤层气井的产水量和产气量,并与实际的 生产曲线相比较,进行拟合校正,建立合理的预测模型,用于煤层气并未来的产水量和产气量的 预测。

According to this question, basing on analysis of field data, production curve of gas well is drawn up, and its changing low is analyzed, range of reasonable production of gas well is gained.

针对此问题,在充分研究气井现场实际生产资料的基础上,作出气井的生产曲线,研究其变化规律,得出气井合理产量的大致范围;同时从气藏渗流力学理论出发,研究气井渗流规律,结合两者,最终快速地确定出低产气井的合理产量,并在大庆SZ气田中进行了应用,取得了很好的效果。
