Optimal periodic control with the lowest operational cost by limiting total substrate discharge mass was studied. through adding new state variable and using supplement functions, the problem with restriction conditions was converted into nonrestriction problem. in addition, the dynamic searching method of optimal step coefficient was developed to modify the conventional gradient method, consequently the calculation problem of the multivariable optimal periodic control was able to be resolved better. it was found that the operational costs of optimal control under various initial states are distinctly different. a new concept of optimal control under optimal initial state was presented. it is pointed out emphatically that to the treatment system without optimal control condition, the suboptimal control with extensive practical value can be realized according to the results of optima control
著重研究了在限制有機物排放總量時，使其運行費用最低的最優周期控制問題.通過增加新的狀態變量和用補償函數法，將本課題的有約束條件問題化為無約束條件問題，並提出了最優步長參數的動態搜索法來修改傳統的梯度法，從而較完善地解決了多變量最優周期控制的計算問題.研究中還發現了不同初始條件下最優控制所需要的運行費用也大不相同，進而提出了最優初始狀態下最優周期控制的新概念，這對保證出水質量的同時進一步降低污水處理成本來說具有更重要的意義.本文還強調指出：對于尚不具備實現最優控制條件的處理系統，可根據最優控制的研究結果實現具有廣泛實用價值的準最優控制Based on careful division and correlation of substrata of sanjianfang formation in west ling - er area in qiuling oil field, this study confirmed the distributing of the faults in study area, carefully researched the relation among the distributing of the sand body, the distributing of the physical properties and sedimentary microfacies, made quantitative analysis about the reservoir macroscopic heterogeneity, put forward an uniform evaluation standard of substrata ; this study analysed the factor which causes the changing of the production, expounded the development result of waterflooding of sanjianfang formation in the west ling - er area through the ways that the oil ( water ) - occurrence in the oil well, the balance between waterflooding and exploitation and the reservoir exploited ; summed up the characteristics of the movment of the inject water and the rule of the distributing of the remaining oil
本文在對丘陵油田陵二西區三間房組地層進行小層精細劃分和對比的基礎上，落實了斷層在陵二西區的分佈狀況，詳細研究了各小層的砂體分佈、物性分佈與沉積微相及三者之間的關系，對儲層的宏觀非均質性作了定量分析，統一了小層分類評價標準；分析了影響產量變化的因素，從油井見效見水、注采平衡和儲層動用等方面闡述了陵二西區三間房組油藏的注水開發效果，並總結了注入水運動和剩餘油分佈規律。
