For putting forwarding the concept of “ Petrolem
System”, the most important in the thing is inducting
“System Thread”,and the linchpin is organic combination in
time and space between static geology factors and dynamic
geology process ,which embodies contribution by fabric and
fabric to system. Starting thread is that research objects ,
which are taden regard as systems ,are analyzed about these
basic attributes ,fabrics and functions ,and then we optimize
the systems. Starting from System Thread ,we consider that
research on Petroleum System should take the approaches :
the interface and connection between system and its
environment ,decomposing factors and establishing system’s
attributes , synthesizing mutual connection and order of
factors’attributes when they form into systems’functions ,
estimating systems ’validity and redesigning them. The
approaches embody integral process of system thread in
research on petroleum system.
