It is because, on the one hand, surfactant concentration in oil-water interface increased for that weak alkali as a “salt” forced more surfactant molecules into the oil-water interface, on the other hand, weak alkali can react with organic acids in crude oil to form some film forming material (surfactant molecular layer), which can increase the concentration of film forming material [5].
Conclusions (1) The interfacial tension reduction effect of weak alkali ternary system is better than that of the alkali-free binary system, and the ultra-low values for weak alkali ternary system could be reach more rapidly; (2) The influence of polymer concentrations is little on static interfacial tensions, and the higher the concentration of polymer is,the longer the time to reach ultra-low interfacial tension is;(3) The interfacial tensions can still be ultra-low when the concentration of every component was decreased simutaneously in the weak alkali ternary system;(4) Adding Na2CO3 not only could reduce the interfacial tension,but also played a role of sacrificial agent; Acknowledgment The work was financially supported by the National Natural Science Foundation of China (51074033).

In the Ubiquitous-Joint model, the material strength parameters consist of rock cohesion cr, internal friction angle φr, structure plane cohesion cj and internal friction angle φj.
According to the stress state, occurrence of structure plane and material characteristic of model, the failure may occur in either rock mass and structure plane, or in both; So, during the procedure of SRM, value of cr, tan(φr), cj and tan(φj) are reduced with the same factors; When the calculation can not converge, the slope is believed to reach the state of failure.
