Firstly, based on the present research all over the world, a 3d quasi - single phase model is built together with k - equations. the special feature of this model is taking account of the influence of interaction between liquid and gas, that is to say, the influence of interphase drag force, lifting force perpendicular to the relative velocity, virtual mass force and gas or liquid volume fraction in the fluid field have been considered. a 3d two - fluid model is also built in order to describe more accurately the fluid flow on distillation trays by comparing the computational results of quasi - single phase mathematical model with of two - fluid mathematical model
本文在國內外已有的研究基礎上，首先建立了以k - （封閉模型為基礎的三維擬單相流模型，該模型的特點在於充分考慮了氣液兩相間相互作用的影響，即計入了相間曳力、橫向升力、虛擬質量力和氣、液相含率對流場的影響；並建立了塔板三維雙流體模型，主要目的是通過對比擬單相流數學模型、雙流體數學模型的計算結果，建立能夠準確描述塔板上流體流動的數學模型。 -

After studying the contents with " sx - 10 law " concerning the oil and gas ( o & g ) cost of the international oil company, the article has systematically analyzed and compared the sinopec and foreign oil company ' s o & g cost ' s differences, such as its classifications structures, and cost accounting etc. by analyzing the international oil company ' s common o & g cost ' s movement tendency and rule which has been outlined and showing in the recent 10 years, that is between 1991 and 2000, the article has compared and studied the differences in o & g costs between the sinopec and foreign oil company, furthermore, it has taken impersonally part the real and internal reasons in details which has resulted in the differences at home and abroad. for instance, it has concluded the reasons that contribute to the long - lasting higher production cost of the sinopec upstream in three aspects : firstly, it is due to the difference in its resource stratagem, that is, the foreign oil company can realize their o & g resource optimization by the way of resource electing and o & g assets replacement in the world market ; secondly, since most of the sinopec key oilfields have been in the middle or last development period which characterizing the " three high " ( high water containing, high yield and high lifting rate ), it has been an impersonal rule with a higher level of production cost ; finally, another factor resulting in the higher production cost lies in the execrable operating and social environment which has been facing by the domestic oil company and a great amount of non - producing payout which owes to the bad environment
本論文從美國證監會（ sec ）對國外石油公司油氣成本的《 sx4 - 10條例》的內容研究出發，系統地分析和比較了中外石油公司在油氣成本的分類、構成以及核算等方面的差異，並結合近十年來（ 1991 - 2000 ）國外石油公司油氣成本的變化趨勢和變化規律，對中外油氣成本結構和變化呈現出的差異進行了比較和研究，並就導致該差異產生的深層次原因進行了客觀翔實的剖析，文章特別指出，造成中石化上游油氣生產成本居高不下的原因有三個方面： （ 1 ）資源戰略方面，國外石油公司可以通過資源優選和資產置換來實現油氣資源的最優化選擇： （ 2 ）從開發程度上，中石化上游普遍進入以「三高」為特徵的開發階段，生產成本高是客觀規律： （ 3 ）企業面臨的惡劣經營和社會環境以及由此產生的大量非生產支出，也是構成企業生產成本較高的原因之一。 -
