Abstract: The correlative relationship of the development index of oilfield can be established by use of functional simulation theory(such as differential simulation method and NN method), the authors re-searched the oilfield(oil production plant or development unit) and set up the optimal models of measure structure with different goals,including maximum measure oil-output(fixed measure workload ,fixed measure cost);minimum measure cost(fixed measure oil-out-put,fixed measure workload) and maximum economic benefit(fixed measure workload, fixed measure oil-output, fixed measure cost),
which solved the optimal structure problems successfully with each subentry measure oil-output (usually contained fracture oil-output、acidification oil-output、overhaul oil-output、other measure oil-output and so on) and the corresponding measure workload and other de-velopment index of oilfield (or oil production plant). The satisfacto-ry economic benefit can be obtained that applied the models into de-velopment programming in some oilfield, which was in the mid-late stage.
