In this paper, comparative tests have been conducted based on three biosurfactants with different HLB values, rhamnolipid is determined as the optimal bio surfactant for tertiary oil recovery, according to the molecular structure of rhamnolipid, a series of experiments have been performed, two optimal formulas, formula Ⅰ and formula Ⅱ, were screened out based on the principle of gegnion matching with rhamnolipid. Formula Ⅰ: rhammolipid and dodecyl sodium sulfomate concentration ratio is 4000∶1; formula Ⅱ: rhamnolipid, conversion agent and cosurfactant concentration ratio is 500∶1∶10.25 Both the formulas can decrease oil water interface tension to 2 × 10 -2 mN/m, and formula Ⅱ can withstand 80℃ of temperature and 20000mg/L of salinity.

This paper aims at the bio-surfactant combination system used in small well spacing pilot test of Daqing oil field. After the 60 tons RH liquid that we researched and produced by ourselves was combined with other surfactant, we screened and optimized the formulation of ASP combination system that fit small well spacing.

This paper aims at the bio-surfactant combination system used in small well spacing pilot test of Daqing oil field. After the 60 tons RH liquid that we researched and produced by ourselves was combined with other surfactant, we screened and optimized the formulation of ASP combination system that fit small well spacing. Based on the evaluation of the general properties of the formulation, we confirm that RH can increase the range of ultra-low interfacial tension area and reduce the occlusion and adsorption of surfactant. This ASP formulation can increase the oil displacement by 20% compared with water flooding. When the oil displacement efficiency are same the formulation can decrease half of the amount of ORS41. Cost accounting shows this bio-surfactant ASP combination system can reduce the cost by at least 30% compared with original ASP formulation.

A study was made to see the feasibility of using bio-surfactant (rhamnolipid fermentation liquor) as a sacrificial agent in the ASP flooding pilot test. The interfacial tensions between solutions containing only bio-surfactant and/or surfactant (ORS) and crude oil were studied at a constant NaOH concentration. The interfacial tension between bio-surfactant-ORS system and oil is lower than that of ORS alone. The interfacial activity of the compound (mixture) of bio-surfactant...

A study was made to see the feasibility of using bio-surfactant (rhamnolipid fermentation liquor) as a sacrificial agent in the ASP flooding pilot test. The interfacial tensions between solutions containing only bio-surfactant and/or surfactant (ORS) and crude oil were studied at a constant NaOH concentration. The interfacial tension between bio-surfactant-ORS system and oil is lower than that of ORS alone. The interfacial activity of the compound (mixture) of bio-surfactant and ORS is obviously synergetic. Adsorption isotherms of the bio-surfactant and ORS system were established to assess the sacrificial effect of bio-surfactant. Static adsorption experiments indicate that adsorption loss of surfactant (ORS) can be reduced by 25 - 30% by bio-surfactant and ORS mixture or pre-adsorption with bio-surfactant on oil sand. The ASP flooding was tested with bio-surfactant and ORS. The concentration of ORS is decreased by 50% to that of the original ASP flooding in which 0.15% bio-surfactant was added. In the test area, the oil recovery factor is averagely increased by 16.64%(OOIP). The relative concentration of ORS in the produced well effluent for bio-surfactant ASP flooding test is the same as ASP flooding of only ORS.

界面活性研究表明,在一定NaOH浓度下,鼠李糖脂发酵液和表面活性剂按不同比例复配后,可以改善界面活性,界面张力低于以表面活性剂为主剂形成的三元复合体系与原油的界面张力。说明生物表面活性剂与表面活性剂复配后存在着明显的协同效应。生物表面活性剂作为牺牲剂,用其对油砂预吸附后可以降低表面活性剂吸附损失30%左右。在用生物表面活性剂的三元复合驱矿场试验中,表面活性剂用量减少一半情况下,采出井流出物中表百活性剂相对浓度高于未使用生物表面活性剂的三元复合驱矿场试验中流出物表面活性剂的相对浓度。化学驱原油采收率平均提高16.64%以上。图5参7(李道山摘)
