Development trend of coal-rock reservoir damage evaluation methods
摘要
Abstract
In order to systematically review the development trajectory of coal-rock reservoir damage evaluation methods,and address the challenges in selecting appropriate damage prevention and control methods due to fragmented information,dissection and trend modeling were conducted on relevant literatures published during 1982-2023 through a research approach integrating bibliometric and time-series analyses.The following results are obtained.(i)For the constructed model of changing volume of literature over time,the determination coefficients of equations for the 3-year and 6-year observation periods are 0.755 5 and 0.799 4,respectively,indicating a satisfactory fitting of medium-and long-term trends.The equations can be used to reveal the overall development pattern of coal-rock reservoir damage evaluation methods.In contrast,the equation corresponding to 1-year observation period is significantly affected by short-term fluctuations and thus provides a limited interpretability.(ii)The trend fitting for physical and digital evaluation methods shows that both methods exhibit positive correlation between the volume of literature and time for 3-year and 6-year periods.The determination coefficients of the physical method are 0.756 9 and 0.840 1,respectively,while those of the digital method are 0.582 0 and 0.677 8,respectively,indicating that the physical method evolves in a more stable and remarkable trend.(iii)In view of growth trend,the physical and digital methods are similar in the literature volume in the early stage;however,according to the fitting for 3-year and 6-year periods,the physical method reflects growth slopes(1.156 0 and 4.607 1)much higher than those(0.107 7 and 0.428 6)of the digital method,implying that the physical method is dominant and maintains a fast development.It is concluded that the physical method will remain the key evaluation option for a long time in the future.Issues such as sample limitation and prolonged evaluation period associated with the method can be addressed by the integration with the digital method.The integrated physical-digital method for coal-rock reservoir damage evaluation is expected to provide a powerful support for accelerating exploration and development of coalbed methane.关键词
