In order to solve the problem of cement slurry unstable problem of anionic styrene-butadiene latex happened when directly added into to oil well，the suitable stabilizers were optimized by different experiments. The styrene-butadiene latex was composed of 70% of styrene butadiene latex puree，2% of the non ion surface active agent FB-1，1% of non ion surface active agent FB-2，0.4% of the anion surface active agent YB-1，0.25% of the anion surface active agent YB-2 as well as a certain amount of preservatives and deionized water，denoted as BZT-L1. It was studied on the latex cement slurry properties of mechanical stability， salt resistance and temperature resistance. At the temperature of 50—150℃ and the pressure of 25—75 MPa，latex cement slurry systems containing 6% of BZT-L1 exhibited excellent stability，and the thickening curve of cement slurry showed right angle thickening. Besides，the BZT-L1 cement slurry exhibited excellent half-saturation salt resistance properties，and thickening curve of cement slurry showed right angle thickening. The conventional density slurry containing BZT-L1 not only reduced the fluid loss （less than 50 mL）but also exhibited excellent combination properties，such as good rheological properties，low fluid loss，zero free liquid，and cement slurry density almost zero，etc. Moreover，the cement compressive strength was more than 14 MPa after curing 24 h.
