The software takes the stratification test data and the water absorption profile data as the
constraints, forms the stratification (section) water injection observation system, carries
on the stratification (section) historical simulation to the water injection well, and
improves the simulation accuracy of the connected production well. According to the error
theory, the software calculates the error of the simulation index of the whole area, well
pattern, single well and sedimentary unit, establishes the parameter adjustment template
combined with expert experience, studies the stratification (segment) historical simulation
technology based on ECLIPSE software by numerical analysis method, and distinguishes the
remaining oil type by combining quantitative description with computer graphic recognition
technology. Based on the remaining oil types and quantitative results, the single well which
needs adjustment potential exploitation and its corresponding adjustment potential
exploitation measures are selected to form the numerical simulation data flow, automatically
send the work and extract the prediction results of the scheme, and optimize the scheme. The
main functional modules are as follows:
