【摘要】：聚合物驅(qū)在國內(nèi)油田是較為普遍的驅(qū)油手段。隨著開采力度的加大,我國越來越多的高溫高礦化度油藏被開采出來,但普通的聚合物具有不耐高溫、耐鹽性差、易降解等缺點,因此,一系列新型高效的聚合物被研制出來。研究采油污水處理技術(shù)時,除了單一的物理方法,科研工作者現(xiàn)在轉(zhuǎn)向高效的化學(xué)處理劑的研發(fā)上,絡(luò)合劑就是目前應(yīng)用最廣泛的化學(xué)處理劑,可以改變金屬存在狀態(tài),有效提高聚合物溶液粘度。本文對比了磺化聚丙烯酰胺和部分水解聚丙烯酰胺的抗溫耐鹽性能上的差異;系統(tǒng)篩選出了8種絡(luò)合劑,降低聚合物溶液中的二價金屬離子濃度從而提高其粘度;且進行抗氧化劑的篩選,并將優(yōu)選出的抗氧化劑與優(yōu)選出的絡(luò)合劑進行復(fù)配;利用最優(yōu)試劑組合進行聚合物溶液粘度穩(wěn)定性實驗和驅(qū)油實驗。實驗結(jié)果表明:(1)二價金屬離子相比于一價金屬離子,更易與聚合物分子結(jié)合,使溶液粘度下降;與部分水解聚丙烯酰胺相比,磺化聚丙烯酰胺具有更優(yōu)異的耐溫抗鹽性;磺化聚合物溶液粘度隨溶液濃度的上升而升高;當(dāng)溫度、礦化度降低時,溶液粘度升高;溶液pH值在11左右時,溶液粘度最高;(2)金屬離子絡(luò)合劑能有效的絡(luò)合水中二價金屬離子,不過在相同條件下,每種絡(luò)合劑的最佳用量都不相同,且每種絡(luò)合劑的增粘效果也不同,其中效果最好的有機絡(luò)合劑是三乙醇胺,無機絡(luò)合劑是葡萄糖酸鈉,與未加絡(luò)合劑的SPAM溶液相比粘度均提高了近2倍;(3)相比空白聚合物溶液以及單一試劑的聚合物溶液,加入復(fù)配試劑后的聚合物溶液粘度最高,可見復(fù)配試劑對于提高SPAM溶液初始粘度十分有效;(4)在粘度穩(wěn)定性實驗中,相比空白聚合物溶液以及單一試劑的聚合物溶液,加入復(fù)配試劑的聚合物溶液的穩(wěn)定性最佳;(5)在驅(qū)油實驗中,加入復(fù)配試劑的聚合物體系相比空白的聚合物體系采收率要提高15%以上。
[Abstract]:Polymer flooding is a more common oil displacement method in domestic oil fields. With the increase of mining intensity, more and more high temperature and high salinity reservoirs have been mined in our country, but the common polymers have the disadvantages of high temperature resistance, poor salt tolerance and easy degradation. Therefore, a series of new and efficient polymers have been developed. In addition to a single physical method, researchers are now turning to the research and development of efficient chemical treatment agents. The complexing agent is the most widely used chemical treatment agent at present. It can change the state of metal and effectively improve the viscosity of the polymer solution. The temperature resistance of sulfonated polyacrylamide and partially hydrolyzed polyacrylamide is compared in this paper. 8 kinds of complexing agents were selected to reduce the concentration of two valence metal ions in the polymer solution and improve their viscosity, and the screening of antioxidants was carried out, and the optimized antioxidants were mixed with the preferred complexing agent; the viscosity stability experiment of polymer solution was carried out with the optimum test agent combination. The experimental results show that: (1) the two valence metal ions are more easily associated with the polymer molecules than the monovalent metal ions, and the viscosity of the solution decreases. Compared with the partially hydrolyzed polyacrylamide, the sulfonated polyacrylamide has more excellent temperature resistance and salt resistance; the viscosity of the sulfonated polymer increases with the increase of the concentration of the solution; when temperature, When the salinity is reduced, the viscosity of the solution increases and the solution pH value is about 11, the solution viscosity is the highest. (2) the metal ion complexing agent can be effective two valence metal ions in the collaterals, but under the same conditions, the best dosage of each complexing agent is different, and the adhesive effect of each complexing agent is different, among which the best organic complexing agent is used. It is triethanolamine, the inorganic complexing agent is sodium gluconate, and the viscosity of the SPAM solution is nearly 2 times higher than that of the uncomplexing agent. (3) the viscosity of the polymer solution after adding the compound reagent is the highest compared to the blank polymer solution and the polymer solution of the single reagent. (4) the reagents are very effective for improving the initial viscosity of the solution; (4 In the viscosity stability test, the stability of the polymer solution added to the compound reagent is best compared to the blank polymer solution and the polymer solution with the single reagent. (5) in the oil displacement experiment, the recovery of the polymer system with the compound reagents is increased by more than 15% compared with the blank polymer system.
