采用集總參數(shù)模型(或“水箱”、“儲(chǔ)罐”模型)對(duì)地?zé)釤醿?chǔ)的未來生產(chǎn)量進(jìn)行評(píng)估是地?zé)釤醿?chǔ)工程中很重要的一環(huán),借助這一類模型可以精確高效地評(píng)價(jià)熱儲(chǔ)生產(chǎn)的可持續(xù)性。關(guān)于低溫地?zé)釤醿?chǔ)的集總參數(shù)模型已經(jīng)日趨完善,然而鮮有針對(duì)高溫地?zé)釤醿?chǔ)或汽-液兩相地?zé)釤醿?chǔ)的集總參數(shù)模擬。此外,以往的集總參數(shù)模型通過采用壓縮率的方式將汽-液兩相流體當(dāng)作單相流體處理?紤]到汽-液混合物的壓縮率會(huì)隨干度及壓力的改變而急劇變化,且熱儲(chǔ)是否為非承壓儲(chǔ)層對(duì)壓縮率也有非常大的影響。因此,這樣的模型存在著很大的不確定性。為了解決這一問題,本文引用干度作為新變量,提出了一個(gè)能被廣泛應(yīng)用的兩相集總參數(shù)模型用以模擬地?zé)釤醿?chǔ)的壓力、溫度以及干度響應(yīng)。集總參數(shù)模型作為一個(gè)動(dòng)態(tài)模型,以更少的計(jì)算成本實(shí)現(xiàn)較高精度的模擬。本文所提出的集總參數(shù)模型以水和蒸汽為唯一工質(zhì),提出了兩相以及過熱集總參數(shù)模型。該模型中存在著大量的預(yù)估參數(shù)和熱力學(xué)參數(shù),且水蒸氣性質(zhì)是通過插值法求得。因而該模型是一個(gè)非線性且多參數(shù)的問題,且不易得出優(yōu)化過程中目標(biāo)方程的梯度信息、Hessian陣和Jacobian矩陣。因此,本文采用BFGS擬牛頓法和遺傳算法(Genetic A...
