【摘要】：隨著行油勘探規(guī)模的增人,在我國發(fā)現(xiàn)巨型整裝特人型油田的兒率越米越小,而高速發(fā)展的國民經(jīng)濟(jì)對(duì)石油的需求量不斷增加,為適應(yīng)當(dāng)前經(jīng)濟(jì)形勢(shì),我國石油工業(yè)開發(fā)建設(shè)的目標(biāo)逐漸轉(zhuǎn)向低產(chǎn)、低壓、低滲透油田。我廠管轄的大慶油田外同爾部葡萄花油層就屬于此類“二低”油藏,經(jīng)過二十年的開發(fā)建設(shè),先期投產(chǎn)的老油田已進(jìn)入中、高含水期開發(fā)階段,如何應(yīng)用新技術(shù)提高此類油田采收率,成為當(dāng)前需要攻關(guān)的重要課題。 微生物采油提高采收率技術(shù)以其成本低、適用性強(qiáng)、施工簡(jiǎn)單、不傷害儲(chǔ)層及無污染等優(yōu)點(diǎn)受到石油業(yè)的普遍重視。以烴為碳源的微生物采油技術(shù)主要是利用其生物作用和生物化學(xué)作用來提高采收率的,即依靠其在油藏中利用原油中的重?zé)N組分為碳源,通過自身的生長(zhǎng)、代謝和繁殖改善原油性質(zhì);代謝大量有益產(chǎn)物,降低了油藏中油、水和巖石的界面張力,提高原油的流動(dòng)性。但是所選菌種能否在地層條件下生長(zhǎng)和繁殖、代謝產(chǎn)物能否有效地改善原油流動(dòng)性、其生物化學(xué)作用如何啟動(dòng)剩余油以及低滲透油田采用微生物驅(qū)油技術(shù)的最佳時(shí)機(jī)等問題是該技術(shù)得以推廣的關(guān)鍵。 本文在室內(nèi)物理模擬實(shí)驗(yàn)的基礎(chǔ)上,研究了微生物在多孔介質(zhì)中與原油的作用,生長(zhǎng)、繁殖和運(yùn)移規(guī)律及該技術(shù)對(duì)提高采收率的影響;以數(shù)值模擬研究為手段,探討了微生物驅(qū)油技術(shù)的合理濃度、用量、時(shí)機(jī)及注入方式等:同時(shí),在宋芳屯油田開展微生物驅(qū)油現(xiàn)場(chǎng)試驗(yàn),結(jié)合油田儲(chǔ)層物性、構(gòu)造特征、剩余油分布等分析了試驗(yàn)井組的受效規(guī)律與特點(diǎn),初步探討了微生物驅(qū)油技術(shù)對(duì)不同儲(chǔ)層油井的適應(yīng)性,指出了該技術(shù)在油田的發(fā)展和應(yīng)用前景。
[Abstract]:With the increase in the scale of oil exploration, the rate of finding giant oil fields in China is getting smaller and smaller, and the demand for oil in the rapidly developing national economy is increasing, in order to adapt to the current economic situation. The target of development and construction of petroleum industry in China has gradually turned to low-yield, low-pressure and low-permeability oil fields. The Tongerbian Putaohua reservoir in Daqing oil field under my factory's jurisdiction belongs to this kind of "second low" reservoir. After 20 years of development and construction, the old oil field that was put into production in advance has entered the stage of development in the middle and high water cut period. How to use new technology to improve oil recovery has become an important task. Microbial oil recovery technology has been widely paid attention to by oil industry because of its advantages of low cost, strong applicability, simple construction, no damage to reservoir and no pollution. Microbial oil recovery technology with hydrocarbon as carbon source mainly uses its biological and biochemical action to improve oil recovery, that is, depending on the use of heavy hydrocarbon components in oil reservoir as carbon source, the microbial oil recovery technology can grow through its own growth. Metabolism and reproduction to improve the properties of crude oil; By metabolizing a large number of beneficial products, the interfacial tension of oil, water and rock in the reservoir is reduced, and the flowability of crude oil is improved. But can the selected bacteria grow and reproduce under stratigraphic conditions, and can the metabolites effectively improve the flow of crude oil? The key to popularize this technology is how to start the remaining oil by biochemical action and the best time to adopt microbial oil displacement technology in low permeability oil fields. On the basis of laboratory physical simulation experiments, the interaction, growth, propagation and migration of microorganisms with crude oil in porous media and the effect of this technique on oil recovery were studied. By means of numerical simulation, the reasonable concentration, dosage, timing and injection mode of microbial oil displacement technology are discussed. At the same time, the field test of microbial oil displacement is carried out in Songfangtun Oilfield, combining with reservoir physical properties and structural characteristics. The distribution of residual oil is analyzed in this paper, the effect law and characteristics of test well group are analyzed, the adaptability of microbial oil displacement technology to oil wells in different reservoirs is discussed, and the development and application prospect of this technology in oil field are pointed out.
