Abstract

Deep extraction of coalbed methane holds great promise in new energy development. Main challenge is how to promote gas seepage and further enhance extraction efficiency. One of effective approaches to enhance seepage dominance is optimizing borehole arrangement. In this work, a calculation method for free state conversion rate of adsorbed gas was presented based on the coupling between permeability and gas content. Subsequently, the effects of loading stress and borehole arrangement on stress, strain response and gas distribution in extraction areas were analyzed via simulation. Eventually, the contributions of multi-hole extraction to gas seepage were quantitatively explored. Results indicate that the increase in loading stress can enhance stress and strain response in extraction areas. After adjusting from one-hole to three-hole arrangement, the growth ratio of stress and strain can be further enhanced by around 25%, and porosity by about 0.06%–0.21%, which effectively broadens transport channels; moreover, gas diffused from matrix can seep out promptly, avoiding accumulation in area outside boreholes; more importantly, areas with conversion rates below 80% can reach 24.21%, and areas within 50% are likewise up to 8.27%, nearly three folds of one-hole arrangement. As expected, the multi-hole arrangement significantly contributes to seepage and extraction of coalbed methane.
