Zhang Lina, Liu Xin, Zhang Yaozu. Formulation of production plan in overpressure shale gas reservoir[J]. Petroleum Reservoir Evaluation and Development, 2018, (4): 73-76. DOI: 10.13809/j.cnki.cn32-1825/te.2018.04.015.
By the adjustment of the global energy consumption structure
the progress of shale gas exploration technology and the clean feature of shale gas
the rational development of shale gas reservoir has been the popular research direction. Therefore
how to make efficient and stable development plan of gas reservoir is very important. Taking the shale gas reservoir in Pingqiao as the research target
we established the horizontal fracturing well models with duel media by the software CMG to simulate the influence of the production allocation and recovery time after shut in on the development effect. The analysis suggests that different fracturing effects need different rational production allocation. The worse the fracturing rec
onstruction effect is
the lower the rational production will be
along with that are lower final recovery ratio and shorter stable production time. After the stable production period
the wells could be shut in for 20
30 days in order to recover the pressure and daily production. It is concluded that the allocation system and fracture effects affect mostly on the overpressure shale gas development. The key of the high and stable production is to improve the seepage capacity and reasonable distribution in the fracturing reconstruction region.
