声波全波列测井资料分析处理技术及应用

针对川西致密碎屑岩储层声波全波列测井信息特征，开展了声波全波列测井信息提取技术的研制工作，分析了各种提取分波信息方法的特点并对其进行了比较，在此基础上实现了多方法的综合提取。开发了声波全波列测井资料的人机交互处理技术，大大提高了各种分波信息处理的准确性。引入裂缝率的概念，通过对裂缝率的计算和分析实现了对储层裂缝的半定量评价。这一技术的开发应用使得测井对储层裂缝的分布和发育情况展现得更直观，刻画得细致。该技术及时应用到了川西中深层的勘探和开发中，分析了储层的含气性、渗透性、裂缝性以及岩石弹性参数等，对裂缝性储层的评价进一步定量化。

Sonic Full Wave Logging Data Processing Technique and Its Applications

According to full wave sonic logging information features of dense detrital reservoir in the west of Sichuan, we studied how to extract the full wave array data and compared various methods of picking up wavelets, based on which a multi-methods integrated extracting technique is worked out. An interactive processing technique of full wave sonic logging data is developed to enhance the veracity of various wavelets. The concept of fracture ratio is introduced for half quantitative evaluation of reservoir fractures. Through calculation and analysis of fracture ratio, the reservoir fracture distribution and growth are indicated more clearly and particularly. This technique is used in mid-depth layers exploration in the west of Sichuan in time, and the gas contents, permeability, fracture along with rock elasticity are calculated, therefore, further quantifying the fracture reservoirs.
