  本文選題：牛心坨油田 + 稠油冷采　； 參考：《浙江大學(xué)》2015年碩士論文

【摘要】：牛心坨油田原由含蠟量較高,黏度高和凝固點(diǎn)高,按照油品性質(zhì)劃分在國內(nèi)屬于高凝稠油,受由品自身的特殊性質(zhì)影響,主要應(yīng)用熱水循環(huán)伴熱工藝和電加熱伴熱工藝。隨著牛心坨油田的綜合含水逐步升高,達(dá)到72.6%,已進(jìn)入高含水期開采階段,該油田所采用的兩項(xiàng)生產(chǎn)工藝已不適合當(dāng)前開采需要,暴露出的問題日益突出,如能耗大、管理難度大、維護(hù)費(fèi)用高等問題,已經(jīng)嚴(yán)重制約了該油田的發(fā)展和降本增效的進(jìn)程,因此,實(shí)施稠油冷采工藝研究對牛心坨油田的長期開發(fā)具有很重要的意義。本文在對牛心坨油田開采工藝原理、現(xiàn)狀分析的基礎(chǔ)上,通過對油田產(chǎn)出液性質(zhì)的變化、含水變化、凝固點(diǎn)變化、黏度變化情況進(jìn)行研究,同時開展大量的室內(nèi)試驗(yàn)與現(xiàn)場試驗(yàn),確定牛心坨油田油井實(shí)施稠油冷采的可行性及必要性,同時對稠油冷采生產(chǎn)配套工藝方面進(jìn)行了研究與分析,如井簡化學(xué)降黏技術(shù)、稠油撈油技術(shù)、井口提溫伴熱技術(shù)等事方面,通過研究最終確定了以稠油冷采工藝為主,以撈油生產(chǎn)工藝為輔,代替熱水循環(huán)伴熱工藝與電加熱伴熱工藝,最大限度的降低牛心坨油田的開采成本,為區(qū)塊開發(fā)后期的綜合調(diào)整、部署奠定基礎(chǔ)。
[Abstract]:Niuxintuo oil field is originally characterized by high wax content, high viscosity and high freezing point. It is classified as high condensable heavy oil in China according to the oil properties, which is affected by the special properties of the oil itself. The hot water circulation heat tracing process and the electric heating tracing technology are mainly used in Niuxintuo Oilfield. With the gradual increase of comprehensive water cut in Niuxintuo Oilfield to 72.6, it has entered the stage of high water cut. The two production processes adopted in Niuxintuo Oilfield are no longer suitable for current exploitation needs, and the problems exposed are becoming increasingly prominent, such as high energy consumption. The problems of difficult management and high maintenance cost have seriously restricted the development of the oilfield and the process of reducing cost and increasing efficiency. Therefore, it is of great significance to carry out the research of heavy oil cold recovery technology for the long-term development of Niuxintuo Oilfield. Based on the analysis of the principle and present situation of the production technology in Niuxintuo Oilfield, this paper studies the change of the properties of the produced fluid, the change of water cut, the change of freezing point, and the change of viscosity. At the same time, a large number of laboratory tests and field tests were carried out to determine the feasibility and necessity of the cold recovery of heavy oil in Niuxintuo Oilfield well. At the same time, the matching technology of heavy oil cold recovery production was studied and analyzed, such as well simplification and viscosity reduction technology. In the aspects of heavy oil recovery technology and wellhead temperature tracing technology, the cold recovery process of heavy oil is the main process, the production process of heavy oil is supplemented by the production process of heavy oil, instead of hot water circulation heat tracing process and electric heating heat tracing technology, and so on. To reduce the production cost of Niuxintuo oilfield to the maximum extent, and to lay the foundation for the comprehensive adjustment and deployment of the block in the later stage of development.
