井筒声场研究回顾与展望

The acoustic theory and borehole acoustic field distribution study and it's applied prospects

声波测井是测井学科的三大方法之一,在储层评价中起到了重要作用.随着陆上油气勘探目标趋向孔隙结构复杂、非均质性强的油气储集层,基于地层各向同性介质的测井理论显露弊端;因此研究复杂地质条件下的井筒声场分布特征、为储层解释和发展测井新方法提供理论依据成为必然.本文对井筒声场研究进行了回顾,并就当前井筒声场研究现状进行了总结,对其发展趋势和应用前景进行了分析.

Acoustic is one main method for well logging, and it takes an important role for reservoir estimate. As the oil exploration aimed at anisotropy inhomogeneous porous reservoir presently, It is important to study the acoustic theory and borehole acoustic field distribution with numerical simulating so as to invent new logging methods and equipments to obtain enough information to evaluate the complex reservoir characters quantificationally and identify the hydrocarbon zone accurately. This paper gives an review about acoustic theory and numerical simulation study, and point out it's developing trend and applied prospects.
