簡介：煤層氣資源量的大小、分布是煤層氣地質評價的重要內容，資源量計算的準確與否直接影響到煤層氣開發的經濟效益。我國煤層氣資源潛力巨大，經過十幾年的研究與勘探實踐，在地質理論和勘探技術等方面都取得了豐碩成果。但如何總結出一套適合我國地質特征的資源量評價方法尚處于起步階段，因此所以非常有必要對煤層氣資源量的預測問題進行進一步研究。在煤層氣儲量計算中，含氣量這一參數至關重要。本文將灰色系統理論應用于沁水盆地中南部煤層含氣量的預測中。首先通過對現有各種灰色關聯度公式的對比研究，提出一種新的灰色關聯度量化模型，并利用該關聯度分析了研究區影響煤層含氣量的主要因素；關聯結果與地質分析相吻合，證明了其可行性。然后根據研究區煤層含氣量序列的數據特點，對傳統GM1，1模型進行了改進。按照緩沖算子的基本理論，構建了若干新的強化、弱化緩沖算子，后建立緩沖算子優化GM1，1模型，提高了GM1，1模型的預測精度；通過對傳統GM1，1模型背景值和初始條件的同時改進，提出了優化GM1，1模型；經過檢驗，利用該模型對研究區深部煤層的含氣量進行了定量預測鑒于非等間隔序列的廣泛存在，在對現有非等間隔GM1，1模型進行研究改進后，提出了累減等間隔化GM1，1模型；并利用其建模理論分別建立了研究區含氣量與參數埋深、RO和灰分的定量預測模型。該模型在煤層含氣量預測中的成功應用，極大拓寬了GM1，1模型的應用范圍。本文還將灰色多變量GM0，N模型應用于含氣量預測中，建立了研究區中部煤層含氣量的GM0，5模型；并將BP網絡與GM0，N模型相結合建立了灰色神經網絡GM0，N模型，通過對該組合模型建模理論的深入研究，使其在含氣量預測中具有了比單個預測模型更高的預測精度。在應用灰色預測模型對煤層含氣量進行預測后，利用容積法按不同級別、不同區塊、不同煤層對研究區煤層氣儲量進行了計算。后利用基于指數型白化權函數的改進灰色聚類方法對研究區煤層氣的有利勘探區塊進行了評價，優選出有利勘探區塊為研究區南部的樊莊潘莊區塊和沁水翼城區塊。研究過程中，為便于灰色系統理論在實際問題中的應用，利用VC60和MATLAB70對灰色系統理論的主要算法進行了程序實現。

簡介：石油加工過程中，各裝置生產設備被控對象很多。例如換熱器、加熱爐、蒸汽鍋爐、氣壓機、精餾塔、分餾塔、反應器等。其中被調量通常是溫度、壓力、液位、餾分、成分和轉速等。從70年代以來，煉油化工一直以生產的平穩和安全為主要目標，因此基于古典控制理論設計的PID常規控制以其簡單、容易理解和掌握一直得到廣泛應用，即使在廣泛推廣先進控制的今天，仍有80％以上的控制回路由PID常規控制承擔。但是，這種生產方式和控制水平，不能使裝置達到最佳工況，生產裝置約有15％左右的效益沒有挖掘出來。九十年代前，因為缺少有效的工程化手段挖掘，使這部分效益白白流失。隨著市場競爭的加劇和國際先進控制技術的迅速發展，應用先進控制技術提高產品質量和效益，已成為煉油化工技術改造中的重要內容。保證“安、穩、長、滿、優”運行的一個重要手段。它是企業挖潛增效、投資少見效快、提高競爭力的一個戰略措施，是衡量一個企業技術進步、提高效益潛力大小的一項標志。國外煉廠先進控制技術應用顯示，它能給煉油廠帶來了巨大的經濟效益。本文以國內常規石油加工工藝過程控制為背景，具體介紹了對武漢石化催化裂化裝置采用一種實時優化控制方法的實踐過程。通過催化裂化相關積分優化控制的實際應用，對系統的性能進行了標定，從標定的數據可以看出，該系統可以提高單一產品收率047％到2％左右，可提高加工每噸原料的經濟效益，取得了較好的效果。
