补偿声波测井在裂缝地层的周波跳跃教学实验设计

Experiment Course Design for Cycle Skip of Acoustic Logging on Fracture

声波测井是石油勘探的重要测量手段之一,而其在裂缝或气层中的周波跳跃现象是该测井方法的典型响应特征。为了满足勘查技术与工程专业学生的理论及实践教学需要,本文通过设计并制作等比缩小的声波测井单发双收声系,利用天然岩石模型井中的接缝视作裂缝,通过声系在模拟裂缝中的响应,实现补偿声波测井在教学实验中的周波跳跃现象。本实验有利于学生更好地掌握声波测井的工作原理及其在石油勘探开发过程中的应用,增强了学生的实践动手能力。

The acoustic logging is one of the most important measurement methods in oil exploration.The Cycle Skip is the typical phenomenon of acoustic logging in fracture or gas formation.In order to meet the need of theory and practice of teaching for the students who study in exploration technology and engineering.The Geometric scaled sigle-emission and double-receiving acoustic sonde is designed.And the rock interfaces are considered as fracture of formation.Then the Cycle Skip phenomenon can be measured by using the sonde in teaching laboratory.Therefore,the designed experiment can help students to know the principle and applications well and improve their practical ability.
