Pressure maintenance such as gas cycling which re-injection of produced lean gas into the reservoir are common practices and effective measures to improve the development performance of gas condensate reservoir. However, effectively control of gas channeling and control water cut of horizontal well in gas reservoir with aquifer both the keys to improve the development effectiveness. There are many factors that respond for gas channeling and water cresting, single factor experiment is difficult to obtain reliable result. Orthogonal experimental design, also called Taguchi experimental design, is widely used in various fields of scientific research. This paper applied Taguchi experimental design, an L9 orthogonal was used to the X gas reservoir numerical simulation to carry out sensitivity analysis among four factors which are the well pattern, gas cycle time, gas offtake, recirculating ratio.

Reservoir Conditions

Both horizontal well and fractured-horizontal well have been widely used to develop TGRs. However, the costs of horizontal well and fractured-horizontal well are much higher than the vertical well. Therefore, it is necessary to consider the reservoir conditions for evaluating the potential benefit when choosing well pattern or designing well parameters. In this paper, a simulator of simulating the development of TGRs including slippage flow and stress dependence in matrix, and high-velocity non-Darcy flow and stress effect in hydraulic fractures was firstly developed. Then, it was used to study the development effects of different TGRs using different well patterns and well parameters. Based on the simulation results, the incremental ratio models of horizontal well to vertical well and fractured-horizontal well to horizontal well were achieved. These models can be used to predict the incremental production using horizontal well or fractured-horizontal well. We also obtained the plates of choosing well pattern and designing the corresponding parameters to achieve a good profit in the field.
