Experimental study on interlayer interference of coalbed methane reservoir under different reservoir physical properties and pressure systems

Abstract Multilayer commingled production is the most efficient development technique of coalbed methane under the condition of multiple coal seams. However, due to the differences in physical properties between multilayer superimposed gas-bearing systems, interlayer interference severely limits coalbed methane development in commingled production. To achieve multilayer-commingled production, interlayer interference must be reduced and the combination of production layers must be optimized. Physical simulations are an effective measure to achieve this goal. According to the characteristics of multiple thin interbeds, strong reservoir heterogeneity and interlayer pressure difference in the Surat basin, a physical model is established to simulate the multilayer-commingled production process of coalbed methane reservoirs and the gas production contribution, and a pressure change of each layer is analyzed. The greater the interlayer pressure difference, the more obvious the early backflow phenomenon of the low-pressure layer, the more obvious the difference of layered production contribution in the later stage, the lower the degree of commingled production and recovery, and the stronger the interlayer interference. In view of these, this study proposes a new experimental method named the succession production. The novelty of this method is to control the commingled production time, that is, the high-pressure layer is produced first, and the low-pressure layer is combined when the interlayer pressure is consistent. The results show that this method can eliminate the early backflow phenomenon of the low-pressure layer and reduce interlayer interference. Furthermore, the characteristics of interlayer interference and the change law of multilayer-commingled production capacity of succession and commingled production are clarified, providing theoretical and technical support for reducing interlayer interference and optimizing production layer combination to promote the efficient development of multiple thin interbedded coalbed methane reservoirs.

However, due to the differences in physical properties between multilayer superimposed gas-bearing systems, interlayer interference severely limits coalbed methane development in commingled production. To achieve multilayer-commingled production, interlayer interference must be reduced and the combination of production layers must be optimized. Physical simulations are an effective measure to achieve this goal. According to the characteristics of multiple thin interbeds, strong reservoir heterogeneity and interlayer pressure difference in the Surat basin, a physical model is established to simulate the multilayer-commingled production process of coalbed methane reservoirs and the gas production contribution, and a pressure change of each layer is analyzed. The greater the interlayer pressure difference, the more obvious the early backflow phenomenon of the low-pressure layer, the more obvious the difference of layered production contribution in the later stage, the lower the degree of commingled production and recovery, and the stronger the interlayer interference. In view of these, this study proposes a new experimental method named the succession production. The novelty of this method is to control the commingled production time, that is, the high-pressure layer is produced first, and the low-pressure layer is combined when the interlayer pressure is consistent. The results show that this method can eliminate the early backflow phenomenon of the low-pressure layer and reduce interlayer interference. Furthermore, the characteristics of interlayer interference and the change law of multilayer-commingled production capacity of succession and commingled production are clarified, providing theoretical and technical support for reducing interlayer interference and optimizing production layer combination to promote the efficient development of multiple thin interbedded coalbed methane reservoirs.

abstract	Abstract Multilayer commingled production is the most efficient development technique of coalbed methane under the condition of multiple coal seams. However, due to the differences in physical properties between multilayer superimposed gas-bearing systems, interlayer interference severely limits coalbed methane development in commingled production. To achieve multilayer-commingled production, interlayer interference must be reduced and the combination of production layers must be optimized. Physical simulations are an effective measure to achieve this goal. According to the characteristics of multiple thin interbeds, strong reservoir heterogeneity and interlayer pressure difference in the Surat basin, a physical model is established to simulate the multilayer-commingled production process of coalbed methane reservoirs and the gas production contribution, and a pressure change of each layer is analyzed. The greater the interlayer pressure difference, the more obvious the early backflow phenomenon of the low-pressure layer, the more obvious the difference of layered production contribution in the later stage, the lower the degree of commingled production and recovery, and the stronger the interlayer interference. In view of these, this study proposes a new experimental method named the succession production. The novelty of this method is to control the commingled production time, that is, the high-pressure layer is produced first, and the low-pressure layer is combined when the interlayer pressure is consistent. The results show that this method can eliminate the early backflow phenomenon of the low-pressure layer and reduce interlayer interference. Furthermore, the characteristics of interlayer interference and the change law of multilayer-commingled production capacity of succession and commingled production are clarified, providing theoretical and technical support for reducing interlayer interference and optimizing production layer combination to promote the efficient development of multiple thin interbedded coalbed methane reservoirs. © The Author(s) 2022
