The preparation of avermyctin emulsions in water was achieved by mixing the surfactants polyoxyethylene (10) octylphenyl ether (OP10), polyoxyethylene styrenated phenol ether (602), and polyoxyethylene (40) castor oil ether (EL-40) with polyoxyethylene (20) castor oil ether (EL-20), separatively. Emulsion stability was investigated by analyzing the hydrophile-lipophile balance, critical micelle concentration, and surface tension. Then, the surfactants of polyoxyethylene polyoxypropylene styrenated phenol ether (1601), block copolymer (L64), and octyl phenyl polyoxyethylene phosphonate were added to the emulsion made by blending EL-40 and EL-20, separatively. The stability of the emulsions was investigated further and discussed in terms of droplet size, surface tension, and zeta potential.

In addition, other operation condition, such as soapless seeded preparation schedule or without seed, could meet the requirement of the larger particle sizes, broader particle sizes distribution and lower viscosities. Besides the increment of addition rate induces the peel strength and tack decreased and the holding power increased for the PSA tapes that are made from the multicopolymer latexes, the above operation conditions which lead the particle sizes to enlarge would increase the peel strength and tack, and decrease the holding power.

By studying reservoir rock characteristics, diagenesis and physical property, investigation showed that there were distributary channel, branch channel, mouth bar, distal bar, sand sheet, lakeshore, shallow lake and limestone flat . we concluded that the reservoir of N1～N21 is low porosity and permeability reservoir with the types of primary porosity and secondary intergranular porosity, which is in the early diagenetic stage B into the late diagenetic stage A subperiod. The role of effecting reservoir physical property is deposition, cementation, dissolution and tectonic rupture. After researching of reservoir, we divided it into three categories and division the favorable facies belt and relatively favorable. We think that the favorable facies belt is braided river delta front and partly shallow lake in east of the Fault Ⅶ. favorable reservoir is in the first and the second class.
