Abstract:

By comparing the similarities between constant pressure exploration of shale gas and fixed drawdown exploitation of confined groundwater, through the establishment of correspondence indicators between the two, exampled by typical shale reservoir parameters from the USA Barnett shale annual production variation pattern, studying from a hydrogeology perspective, a hydrogeological conceptual model was established to stimulate shale gas exploitation by using GMS(groundwater modeling system) software. The result of model identification and verification shows that, among the 11 fitting values, 6 relative errors are within 5%, 4 relative errors are within 10%, and only 1 is approximately 20%, which indicates that the fitting results are quite desired; it also illustrated that hydrogeological methods in shale gas exploitation are reasonable, and it also showed that in the process of mining, shale gas production is composed of free gas and adsorbed gas, after the entire collection of free gas, the gas yield is supported by the desorbed gas basically; the desorption gas will be re-adsorbed. If there exist fractures in the overlying layer, the number of years and yield for mining decrease along with the fracture increasing. If the fractures in the overlying layer increase as many as 25%, 50%, 75%, and 100% of microfractures zone (Ⅱ/Ⅲ zone), the number of years for mining will decrease to 6 years, 4 years, 2 years, and 1 year accordingly; in different circumstances, with the same mined year, the yield decreases accordingly too. In each case, the ratio of the annual output to that of the original decreases accordingly too. When the boundary conditions change, the lateral boundary (the lower boundary or the right boundary) is set to permeable fault respectively, whether its permeable abilities are 25%, 50%, 75% or 100% of the microfractures zone (Ⅱ/Ⅲ zone), the fixed drawdown (constant pressure) mining conditions can't be met. Thus, the boundary conditions have more influence on shale gas with respect to the overlying/underlying rock. The sensitivity analysis showed that the change of source and sink terms has much greater influence on the gas yield than that of permeability.It is concluded that to promote by all means the desorption of the adsorbed gas is crucial, even determinable, to shale gas production in a certain degree of fracturing. Some suggestion is proposed to exploit shale gas.

Key words: shale gas constant pressure exploitation, analogy, confined groundwater fixed drawdown exploitation, GMS (groundwater modeling system)
