摘要

提高煤层气采收率是实现煤层气大规模有效开发的重要需求。现有研究表明,在岩心尺度下,微波具有提高煤层气采收率的可行性,但在矿场尺度下的相关研究却较为缺乏。为此,建立矿场尺度下的微波加热井模型,对煤层内电磁场、温度场及力学场进行耦合,探讨微波加热参数的影响因素,并对工艺参数进行了优化,确保微波加热井的有效性和稳定性。研究表明:微波加热井以铜波导管(BJ22或BJ26型)及陶瓷套管材料组成的直井或水平井为主;煤层和井筒的温度和热应力与微波功率和加热时间成正相关关系,近井地带煤层由自身介电损耗产生热量,远井地带煤层主要靠接触传热升温;500 W-100 W交替加热33 d的微波工作模式改善了煤层的有效开采性和工作稳定性;仅靠优化工艺参数不能满足实际应用需求,应综合使用间歇式循环变功率微波加热模式、吸波介质强化煤层导热技术、水力压裂等技术提高微波加热储层的实际效果。该研究成果可为微波强化煤层气开采技术的推广应用提供技术支撑。

Abstract

Enhancing the recovery rate of coalbed methane is an essential requirement for achieving large-scale and effective development of coalbed methane. Existing studies have shown that microwaves have the feasibility of improving coalbed methane recovery rate at the core scale, but relevant studies at the mine scale are relatively scarce. For this reason, a microwave heating well model at the mine scale is established to couple the electromagnetic field, temperature field and mechanical field within the coalbed, to explore the influencing factors of microwave heating parameters, and to optimize the process parameters, thereby ensuring the effectiveness and stability of microwave heating wells. The study shows that: Microwave heating wells are mainly vertical or horizontal wells, which are made of copper waveguides (BJ 22 or BJ 26 type) and ceramic casing materials, the temperature and thermal stress in the coalbed and wellbore are positively correlated with microwave power and heating time. The coalbed in the vicinity of the well generates heat by its own dielectric loss, while the coalbed in the area far from the well mainly relies on contact heat transfer to increase temperature. A microwave operating mode of 500 W to 100 W over 33 days has improved the effectiveness and operational stability of the coalbed. Optimizing process parameters alone cannot meet practical application requirements; therefore, a combination of intermittent cyclic variable power microwave heating patterns, microwave-absorbing medium enhanced coalbed thermal conduction technology, and hydraulic fracturing techniques should be employed to enhance the practical effects of microwave heating of the reservoir. The study results can provide technical support for the promotion and application of microwave-enhanced coalbed methane mining technology.
