- •
A principle of dewatering rate in early stage for CBM well is proposed.
- •
The method is based on the characteristic of pressure propagation.
- •
A mathematic model was established to optimize the dewatering rate.
- •
The proposed model was applied in Han-Cheng CBM field and got reliable results.
