The Study Of WISEYE1000 Logging System And Its Application On Daqing Peripheral Oilfield

Daqing oilfield has entered the late stage of development,and the rational development of thin layer has become an important way for the production of Daqing oilfield.However,in the past,the logging equipment has not been able to identify and evaluate the thin layer,which requires more advanced and higher resolution imaging logging system that can be used for thin layer identification.WISEYE1000 imaging logging system is independently developed by Daqing logging company.The system can be used in the operation of open hole,casing well and perforation,and has three main advantages: 1.the system has high compatibility.WISEYE1000 imaging logging system can hang WISEYE1000 downhole instrument itself,and also be able to mount the foreign logging company's 5700 series and LOGIQ series downhole instrument,and the hanging effect is good;2.downhole instrument WISEYE1000 well logging platform itself with the characteristics of light weight,short length which can ensure the effectiveness in the logging field;3.WISEYE1000 imaging logging system can connect almost all known imaging logging instrument.On the basis of large amount of data,the problem of data acquisition,transmission and processing is solved.The system can also be linked to the 0.2 meter ultra thin layer logging tool developed by Daqing logging company,which plays an important role in the identification and evaluation of thin and weak layers.This paper discusses in detail the WISEYE1000 ground system,and selected the dual laterolog tool,high resolution acoustic logging and compensation density logging instrument for the instrument structure and internal circuit analysis.The logging curves of WISEYE1000 downhole instrument and 5700 series are compared based on Daqing peripheral oilfield.At the same time,the logging curves of WISEYE1000 downhole instruments are compared with HY-1000 logging curves in repeatability and consistency.The results show that the system can meet the geological needs of Daqing oilfield and provide high quality logging curves.
