多相孔隙储层声学研究进展

本文回顾了关于油、气、水及水合物多相孔隙储层的声学研究进展,提出了"储层声学"的概念,阐明了其研究意义、研究内涵和方法,并介绍了油、气、水及天然气水合物储层声波模拟的部分新的研究成果。指出应该从声学理论和实验等出发,结合声学储层探测和精细描述的实际情况,如利用声学原理圈闭和估算天然气水合物等,继续深入开展相关基础理论和实验研究工作,丰富储层声学研究内容,更加完善储层声学理论体系,为更好利用声学方法探测和评价储层提供坚实的物理基础和可能的技术支撑。

Research progress in acoustics for multiphase porous reservoirs

Research progress in acoustics for multiphase porous reservoirs saturated with oil, gas,water and/or gas hydrate is reviewed.A new concept,reservoir acoustics,is proposed. Its significance,contents,and methods are clarified.Also,advance in acoustic wave simulation for oil,water,and/or gas hydrate bearing reservoirs is introduced.It is pointed out that, based on theoretical and experiment acoustics,combined with acoustic exploration and characterizations for the reservoirs,for example,how to use acoustic method to map and evaluate gas hydrate concentration,relevant theoretical and experiment studies be conducted unremittingly and profoundly,so that the research contents for reservoir acoustics are enriched and its theoretical system is integrated.This kind of research will provide a concrete physical base and possible technique supports for acoustic exploration and evaluation.
