Processing Of Well Logging Data Based On TPS-9000 High Temperature Tester

In the process of geothermal resources exploration,physical prospecting and logging is an extremely important part.With the development of computer-based digital logging technology,high-precision logging data acquisition and automatic interpretation and analysis of logging data are realized,which greatly improves the ability of logging to solve geological problems.Logging interpretation software deals with logging data,so that logging results can be displayed intuitively by computer in the form of table printing and graphic output.The logging instrument studied in this paper is the TPS-9000 high temperature tester introduced by PRUETT in the 1970 s.It has high precision and high resolution.It can test steam absorption profile,wellbore heat loss and pressure recovery curve of steam injection wells instantaneously or at fixed point.It is the most advanced heavy oil thermal recovery monitoring equipment in the world at that time.However,its logging data files processed by CLGIS are(*).DAT can not be used outside the system,which limits the further use of logging data.This paper intends to study the data structure and storage mode of *.DAT files processed by logging software CLGIS,and decrypt and convert the CLGIS cryptographic format data into plaintext data files that can be widely used to expand the application scope of logging interpretation data.At the same time,it can also solve the problem that "Digital Logging Interpretation System".DAT files can not be used by CGIS,and can also use the converted data.Direct automatic vectorization of logging curves by plaintext data files.Using data automatic vectorization logging curve can not only greatly improve the mapping efficiency,but also reduce the workload of cartographers.According to the requirement of submitting geothermal field exploration report in practical work,this paper designs a method of converting logging data files processed by CLGIS software into open-code data files that can be widely used.The practice proves that this method is correct and feasible.After introducing the process of data conversion and processing,this paper describes the design and construction of data management system.At the end of the article,a screenshot of the completed system is attached.The development of logging data management system provides an innovative basis for the preservation and application of logging data,which is a major technological innovation of this paper.
