测井曲线是多成因的产物.从测量成因看,它与测井仪器的原理密不可分;从测量对象看,它与地质背景相互关联;从井眼环境看,它也包含井眼条件的变化信息.由此可见,测井曲线本身就是地球物理、地质及工程等多因素的响应纠缠体,其中,每一种因素,因其测井响应的成因条件完全不同,它只会按自身固有模式变化.前人对于测井曲线的仪器成因研究较系统,因此,基于仪器原理的测井评价方法也比较成功,但对于地质背景与测井曲线的成因关系识别一直缺乏有效方法,致使测井曲线本身内含的地质信号难以得到有效利用.根据地质成因的某一固有机理,推测或在测井曲线上寻找与该固有机理相吻合的共性变化,是研究测井曲线内含地质属性的一个可能途径,岩石成因就是一个值得探索的切入点.研究表明,岩石成因的主要差别在于形成条件不同,岩石形成条件是决定测井曲线内含地质专属性特征的要因之一.本文分别从成岩时期、成岩物质、成岩温度、沉积相、成岩相及物性特征等多个岩石成因条件的差异,讨论了岩石成因条件的差异与测井地质属性识别的关系.
Well logging is a multifactorial product that is inextricably linked to the well logging tool’s rationale for its origin; it is interrelated with the geological setting from the point of view of the surveyed object; it also includes changes in borehole conditions from the wellbore environment Therefore, the logging curve itself is a multi-factor response entanglement of geophysical, geological and engineering. Each of these factors, due to the completely different conditions for the formation of well log responses, will only respond to its intrinsic mode The predecessors have a systematical study on the genesis of logging instruments. Therefore, logging evaluation methods based on instrumental principles have also been relatively successful. However, there is a lack of effective methods for identifying the genetic relationship between geological background and logging curves, It is difficult to effectively utilize the geological signals contained in it.According to a certain inherent mechanism of geological formation, speculating or looking for the common change coinciding with the intrinsic mechanism on the well log is a possibility to study the geologic attribute in the well log Way and rock cause is a worthwhile exploration.The research shows that the main difference of rock genesis lies in the different forming conditions and the rock formation condition is the decision of logging Line is one of the important geological features of geology.This paper discusses the differences of rock genetic conditions from the difference of genetic conditions of diagenesis, diagenetic matter, diagenetic temperature, sedimentary facies, diagenetic facies and physical properties Relationship of Well Geological Attributes Identification.
