李忠荣等.一种来测并响应函数的新方法.测井技术,1994,18(3):165~171本文介绍一种用变异函数确定测井响应函数的新方法。这种方法与通常所用数学模型或物理模型不同,它将测井曲线反映的地层参数的变化视为一个随机过程,确认地层参数变化具有的两重性,即随机性和相关性,用变异函数研究其变化特征,从而确定测井响应函数。由于它是以实际测井资料为基础进行处理和计算,其结果包含测井仪器系统自身特性、地层、井眼、泥浆、侵入等一切实际存在的环境因素的综合影响,因而响应函数具有更大的准确性和实用性。此外,这种方法不受测井种类的限制,电法、声波、放射性等各种测井资料都可以用这种方法求得各自相应的响应函数。
Li Zhongrong and so on. A new way to measure and respond to functions. LOGGING TECHNOLOGY, 1994,18 (3): 165 ~ 171 This paper presents a new method of determining the well response function using a variogram. This method is different from the commonly used mathematical model or physical model. It treats the change of formation parameters reflected by the well log as a stochastic process, confirms the duality of stratum parameter changes, ie randomness and correlation, Change characteristics to determine the logging response function. Since it is processed and calculated based on the actual log data, the result includes the comprehensive influence of all the actual environmental factors such as the characteristics of the logging tool system, strata, borehole, mud and intrusion, so the response function has a larger The accuracy and practicality. In addition, this method is not limited by the type of logging. In this method, various corresponding well-known response functions can be obtained from various well logging data such as electrical method, acoustic wave and radioactivity.
