WLT, 2002 , 26( 6) :523 - 526According to the need of complicated exploration & development in oil fields , ERA2000 ( Earth Re2sources Acquisition 2000) imaging logging surface system has been developed by XPEIC. It has solvedmany technical probelms , such as tremendous image data processing , handling of numerous external re2spones and output of the interpretation curves. The ERA 2000 imaging logging system design is based onoperating system of Windows N T and VxWorks and avoids the infection of virus , therefore , it allows torun stably and normally. Advanced computer and network technology are used , and international standard2ized VME bus has been used in data acquisition to enhance system′ s stability and reliability. The systemkeeps ahead in real ν time logging images processing. The operating system has user ν friendly windowinterfaces. It can be connected with neutron lifetime loggin...
