Abstract
The problem that water breakthrough of a single well is too early due to uneven water invasion of an existing water-bearing carbonatite gas reservoir is solved. According to the technical scheme, on the basis of an original gas well production allocation scheme of a water-bearing carbonatite gas reservoir, the average water invasion rate of the reservoir is calculated as a stability reference of water invasion rates throughout the production period. A new water invasion-oriented production allocation method is designed from two aspects of stability of water invasion and uniformity of water invasion driving and meanwhile, a reasonable production allocation range is predicted through a traditional deliverability equation, a n d a water invasion-oriented dynamic production allocation mathematical model is established.
