Reasonable production allocation model of gas wells for deep tight gas reservoirs with the edge water

Deep tight gas reservoirs are one of the important unconventional reservoirs. burial, have many characteristics, including diverse accumulation patterns, multiple regulations, low natural energy generation, complex gas–water relationship, and intricate seepage mechanism. These features put forward requirement for new methods a reasonable production allocation horizontal wells optimization such allocations from perspective stress sensitivity. While CO 2 huff-and-puff-based models, numerical simulation thermos-hydrodynamic models been built to solve these issues, there is still lack theoretical guidance allocation, especially with edge-water problem. Here, we present one-dimensional mathematical physical model capture stable movement interface in deep Our results show that starting pressure The gradient increases growth water saturation, which far greater than medium, shallow under same saturation. In addition, by considering pressure, found well has larger upper limit differential smaller velocity, lower allocation. Finally, make comparison between our characteristics real find consistency data. provides framework edge water.
