Design And Software Development Of Image Processing Interpretatio Nsystem Based On CIFlog

Imaging logging technology is a new logging technology developed in the 1990 s.Compared with digital logging technology,imaging logging technology has the characteristics of more information,higher resolution,accurate determination of the bottom,and has stronger adaptability to complex oil and gas reservoirs.The software platform for processing and interpreting exploration well data,which has been put into operation for many years in Daqing Logging Company,has been very mature in processing and interpreting various logging data.Among them,the acoustic and electrical imaging module can process and interpret the data of eight kinds of instruments(FMI,XRMI,STAR,EMI,CAST,CBIL,HDIP,Wise Eye 2000),which has rich experience and excellent technology Potential.However,with the gradual deepening of production and scientific research and the development of logging interpretation technology,the platform framework is difficult to meet the new requirements of interpretation in terms of functionality,ease of use and expansibility,and a new processing and interpretation platform is urgently needed as a carrier.This paper chooses CIFLog logging software platform to develop imaging logging data processing and interpretation software,which is not only a imaging logging data processing and interpretation system that meets the production needs,but also an application development platform that can meet the secondary development of users.Starting from the actual requirements of image logging data processing and interpretation,this paper adds XTF,LIS,DLIS,NTI,CLS formats and other data formats to the platform.The data information recognition is accurate,and the average absolute error of data playback is less than 5 ‰,which can meet the requirements of data processing and interpretation.In order to meet the needs of drawing the result map,the drawing objects such as porosity frequency imaging,vertical two-dimensional curve,cylindrical expansion sine line map are developed.The curve filtering module is developed,which has stronger filtering function than the previous curve filtering module,and users can use it.It provides a more powerful data preprocessing tool for interpreters to filter multiple curves or layers at one time by different methods.It integrates four imaging processing modules,namely,acoustic imaging,cross-dipole acoustic wave,nuclear magnetic resonance and array induction,and develops related human-computer interaction processing functions to provide algorithm calculation parameters and control calculation.The results of the software processing are verified and evaluated by selecting various imaging logging data of several wells.The software developed in this paper can meet the actual needs of imaging logging.At the end of the paper,the development and application prospect of this software are analyzed and prospected.
