油田开发规划措施结构优化模型及其应用

THE MODELLING AND APPLICATION OF PLANNING MEASUREMENT AND STRUCTURE OPTIMATION OF OILFIELD PRODUCTION

利用功能模拟原理 (微分模拟方法及神经网络方法 )建立的油田开发指标关联关系 ,对采油厂或开发单元研究并建立了油田措施产量最大 (定措施工作量、定措施费用 )、措施费用最低 (定措施产量、定措施工作量 )、措施效益最好 (定措施工作量、定措施产量、定措施费用 )的措施结构优化模型。这些优化模型成功地解决了油田 (或采油厂 )各项措施产量 (通常包括压裂、酸化、大修以及其它措施等 )及对应的各项工作量及其它开发指标的最优构成问题 。

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 researched 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-output,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 development index of oilfield (or oil production plant). The satisfactory economic benefit can be obtained that applied the models into development programming in some oilfield, which was in the mid-late stage.
