【摘要】：勝利油田孤島中二中Ng5區(qū)塊由于埋藏深,地層壓力高,不適合蒸汽驅(qū),而多種氣體和化學(xué)劑輔助熱力采油技術(shù)已被實(shí)驗(yàn)和數(shù)值模擬技術(shù)證明是開發(fā)該類油藏的有效開發(fā)方式。本文運(yùn)用實(shí)驗(yàn)方法和數(shù)值模擬手段,模擬了二氧化碳、氮?dú)馀菽�、降粘劑組合輔助熱水驅(qū)(多元熱流體驅(qū))提高采收率技術(shù),詳細(xì)分析了其提高采收率機(jī)理,并且建立了多元熱流體驅(qū)油藏篩選標(biāo)準(zhǔn),對該技術(shù)的推廣應(yīng)用以及進(jìn)一步提高稠油油藏采收率具有重要意義。基于實(shí)驗(yàn)擬合和歷史擬合所獲得的氣體和化學(xué)劑參數(shù)以及油藏地質(zhì)參數(shù),建立了典型區(qū)塊數(shù)值模擬模型,分析了不同多元熱流體驅(qū)開發(fā)方式開發(fā)效果。從提高采收率效果角度,對不同氣體和化學(xué)劑的單獨(dú)注入方式進(jìn)行優(yōu)化,運(yùn)用正交實(shí)驗(yàn)設(shè)計(jì)方法對氣體化學(xué)劑組合注入方式進(jìn)行了優(yōu)化;通過對優(yōu)化結(jié)果的對比分析,發(fā)現(xiàn)泡沫和降粘劑組合輔助熱水開發(fā)方式比泡沫、降粘劑單獨(dú)輔助熱水驅(qū)二者提高采收率總和更高,而二氧化碳和降粘劑組合輔助熱水驅(qū)開發(fā)方式則是相反的效果,說明調(diào)剖后氣體和化學(xué)劑在復(fù)合驅(qū)中才具有更強(qiáng)的復(fù)合增效作用�；跀�(shù)值模擬技術(shù),從受效剩余油分布角度分析了其提高采收率特征。從注入氣體及化學(xué)劑分布和運(yùn)移、溫度分布以及熱流體對原油降粘角度,研究了多元熱流體驅(qū)提高采收率機(jī)理。認(rèn)為單純CO2與單純降粘劑作用時(shí),對原油的降粘效果無法對提高采收率做出明顯貢獻(xiàn),而其它組合方式下,CO2和降粘劑的降粘能力均能得到充分發(fā)揮;在泡沫的作用下,添加劑的運(yùn)移在動用剩余油方面起到了最主要的貢獻(xiàn),泡沫與降粘劑共同作用下油藏受熱效果雖然一定程度上低于單獨(dú)泡沫時(shí)的貢獻(xiàn),但總體仍然大于單純熱水驅(qū)時(shí)的受熱效果。為了獲得多元熱流體驅(qū)開發(fā)的油藏參數(shù)經(jīng)濟(jì)界限,對普通稠油油藏分別進(jìn)行了不同多元熱流體驅(qū)技術(shù)影響因素的敏感性分析�；诓煌筒貐�(shù)多元熱流體驅(qū)開發(fā)效果的影響規(guī)律,結(jié)合經(jīng)濟(jì)評價(jià)方法,建立了多種多元熱流體驅(qū)技術(shù)的油藏參數(shù)適應(yīng)性界限,從而方便根據(jù)油價(jià)動態(tài)指導(dǎo)多元熱流體驅(qū)經(jīng)濟(jì)有效開發(fā)。
[Abstract]:Because of its deep burial and high formation pressure, Gudao Zhongzhong Ng5 block in Shengli Oilfield is not suitable for steam drive, and many kinds of gas and chemical auxiliary thermal oil recovery technology has been proved to be an effective way to develop this kind of reservoir by experiment and numerical simulation technology. In this paper, by means of experimental method and numerical simulation method, the enhanced recovery technology of carbon dioxide, nitrogen foam and viscosity reducer combined with hot water flooding (multicomponent thermal fluid flooding) is simulated, and the mechanism of enhanced recovery is analyzed in detail. The screening criteria for multicomponent thermal fluid flooding reservoirs are established, which is of great significance to the popularization and application of this technology and the further improvement of oil recovery in heavy oil reservoirs. Based on the parameters of gas, chemical agent and reservoir geology obtained by experimental and historical fitting, the numerical simulation model of typical blocks is established, and the development effect of different multi-element thermal fluid flooding methods is analyzed. In order to improve the recovery efficiency, the single injection methods of different gases and chemical agents are optimized, and the combination injection mode of gas chemical agents is optimized by orthogonal experimental design, and the optimized results are compared and analyzed. It is found that the combination of foam and viscosity reducer is more effective than foam in assisting hot water flooding, while the combination of carbon dioxide and viscosity reducer is the opposite. It shows that only after profile control gas and chemical agent have stronger compound synergism in compound flooding. Based on the numerical simulation technique, the characteristics of enhanced oil recovery are analyzed from the point of view of the distribution of effective residual oil. Based on the distribution and migration of injected gas and chemical agent, temperature distribution and viscosity reduction of crude oil by thermal fluid, the mechanism of enhanced recovery by multicomponent thermal fluid flooding is studied. It is concluded that the viscosity reduction effect of crude oil can not be significantly contributed to the oil recovery by the action of simple CO2 and viscosity reducer, but the viscosity reduction ability of CO _ 2 and viscosity reducer can be brought into full play under the effect of foam, and the viscosity reduction ability of CO _ 2 and viscosity reducer can be brought into full play under the effect of foam. The migration of additives plays the most important role in the use of remaining oil. The effect of reservoir heating under the combined action of foam and viscosity reducer is to some extent lower than that of single foam. However, the overall heating effect is still greater than that of pure hot water flooding. In order to obtain the economic limits of reservoir parameters for multicomponent thermal fluid flooding development, the sensitivity analysis of different influencing factors of multi-element thermal fluid flooding technology for common heavy oil reservoirs was carried out. Based on the influence of different reservoir parameters on the development effect of multivariate thermal fluid flooding, combined with the economic evaluation method, the limits of reservoir parameter adaptability of multiple thermal fluid flooding techniques are established. Therefore, it is convenient to guide the economic and effective development of multiple thermal fluid flooding according to the oil price dynamics.
