【摘要】：聚表劑作為一種非常有前景的化學(xué)驅(qū)油劑,已經(jīng)受到了國(guó)內(nèi)外油田以及各大科研院校的關(guān)注。聚表劑驅(qū)作為聚驅(qū)后潛力巨大的三次采油技術(shù),目前已經(jīng)在國(guó)內(nèi)外礦場(chǎng)取得了一定的成功經(jīng)驗(yàn),它解決了三元復(fù)合驅(qū)中儲(chǔ)層結(jié)垢的實(shí)際問題。雖然已經(jīng)有部分科研單位開始研究聚表劑這種新型的驅(qū)油劑,但是聚表劑的物化性能、滲流規(guī)律等等方面并沒有得到足夠的認(rèn)識(shí),對(duì)于現(xiàn)場(chǎng)試驗(yàn)中出現(xiàn)一些問題還不能給出明確的解釋,所以對(duì)于聚表劑的性能、驅(qū)油機(jī)理以及宏觀滲流規(guī)律還需要做更深層次的研究。本文通過室內(nèi)實(shí)驗(yàn),首先采用微觀光刻玻璃模型分別深入研究三種聚表劑的驅(qū)油機(jī)理,并且做出對(duì)比。通過對(duì)這三種聚表劑驅(qū)油機(jī)理實(shí)驗(yàn)的研究和對(duì)比,結(jié)果表明:華鼎I型聚表劑的階段波及面積是三種聚表劑中最大的;在洗油效率方面,海博BI型聚表劑是三種聚表劑中最好的,煉化III型聚表劑在波及面積和洗油效率上都不突出,這說(shuō)明在本文的實(shí)驗(yàn)條件下,煉化III型聚表劑并不適合。本文還對(duì)聚表劑的穩(wěn)定性和抗鹽性物化性質(zhì)進(jìn)行了研究,并且在此基礎(chǔ)上對(duì)聚表劑的注入能力進(jìn)行了研究,以注入能力實(shí)驗(yàn)為基礎(chǔ)優(yōu)選出了三種聚表劑的最佳注入濃度和注入段塞,這三種聚表劑的最佳注入濃度均為1000mg/L,最佳注入段塞均為0.7PV。根據(jù)優(yōu)選出的濃度和段塞,設(shè)計(jì)室內(nèi)實(shí)驗(yàn)研究其滲流規(guī)律,實(shí)驗(yàn)采用四層加厚非均質(zhì)巖心,實(shí)驗(yàn)結(jié)果表明:聚驅(qū)后華鼎聚表劑驅(qū)生產(chǎn)壓差明顯高于海博,低滲與高滲分流率存在振蕩變化趨勢(shì),海博驅(qū)替過程中分流率情況相對(duì)平緩。華鼎I型聚表劑對(duì)剩余油動(dòng)用程度更大;飽和度模型驅(qū)替實(shí)驗(yàn)表明:華鼎I聚表劑對(duì)中低滲透層的動(dòng)用程度高于海博聚表劑,而海博BI聚表劑在中低滲透層波及體積大于華鼎I聚表劑。本文所取得的認(rèn)識(shí),對(duì)現(xiàn)場(chǎng)實(shí)際應(yīng)用提供了理論基礎(chǔ),并且對(duì)現(xiàn)場(chǎng)實(shí)際應(yīng)用具有指導(dǎo)意義。
[Abstract]:As a promising chemical oil displacement agent, Polymer has been paid attention to by oil fields and scientific research institutes at home and abroad. As a tertiary oil recovery technology with great potential after polymer flooding, polymer flooding has already obtained certain successful experience at home and abroad, which has solved the practical problem of reservoir scaling in ASP flooding. Although some scientific research institutions have begun to study the polymer as a new type of oil displacement agent, but the physical and chemical properties of the polymer, the percolation law, and so on, have not been fully understood. Some problems in the field test can not be explained clearly, so the performance of the polymer, the oil displacement mechanism and the macroscopic percolation law need to be further studied. In this paper, the oil displacement mechanism of the three kinds of polymer is studied and compared with the microscopic lithography glass model through laboratory experiments. Through the experimental study and comparison of the oil displacement mechanism of these three kinds of polymeter agents, the results show that the phase sweep area of Huadin I polymeter agent is the largest of the three kinds of polymeter agents, and the oil washing efficiency, Haibo BI type polymeter agent is the best of the three kinds of polymeter agents. The sweep area and oil washing efficiency of refining III type polymeter agent are not outstanding, which shows that the refining III type polymeter agent is not suitable under the experimental conditions in this paper. The stability and the physical and chemical properties of salt resistance of the polymer were also studied, and the injection ability of the polymer was also studied. Based on the experiment of injection ability, the optimal injection concentration and slug of the three kinds of polymer were selected. The optimum injection concentration of these three kinds of polymer was 1000mg / L, and the optimal injection slug was 0.7PV. According to the selected concentration and slug, the percolation law is studied experimentally in the design room, and the four layers thickened heterogeneous core is used in the experiment. The experimental results show that the production pressure difference of Huading polymeter flooding after polymer flooding is obviously higher than that of Haibo. There is a trend of oscillatory variation in low permeability and high permeability distributary rate, and the distributary rate is relatively flat during Haibo flooding. The saturation model displacement experiment shows that Huadin I polymeter agent is more effective than Haibo polymeter agent in the low and middle permeable layers, and the saturation model displacement experiment shows that the production degree of Huadin I polymeter agent is higher than that of Haibo polymeter agent. However, the sweep volume of Haibo BI in low and medium permeable layer is larger than that of Huadin I. The knowledge obtained in this paper provides a theoretical basis for the practical application in the field and has a guiding significance for the practical application in the field.
