The results showed that the solubility of lotus starch was low, the turgidity was closed to sweet potato starch, accordingly was a restrictive swelling starch. A lower transparency (10.4%) was researched in the lotus-seed starch pastes, condensation speed was faster, but it decreased at acidic or alkaline condition. Stronger freeze-thaw stability and lower gel strength was researched in it. It can be from the Brabender viscosity that the lotus-seed starch has a higher gelatinization temperature (77.1℃), better thermostability, stronger retrogradation, weaker cold viscosity stability.

It was considered that the control of the PRD fluid performance and the dosage of flow pattern adjusting agent PF-VIS were the key of the technique. The viscosity of PRD spudding fluid increased rapidly with the decrease of shearing rate, it indicated that it had good sand carrying ability. The spudding fluid was good capacity of high temperature stability under the low shearing rate, its viscosity was much higher than that of traditional drilling fluid, it was beneficial for cutting carrying in big deviated wells and preventing the formation of cutting bed.

The main components in soy protein isolate are 7S and 11S globulins. Studiesof papain on 7S, 11S and mixture of the two proteins suggested that 11S is themain component in SPI to form coagulation. 7S coagulation required higher papainaddition than 11S coagulation, while 11S gel's elastic modular was higher than7S gel. The elasticity of mixture depended on the proportion of 11S. Two proteinases were separated from papain by SP-sepharose cation-exchangechromatography.

首先分离出大豆蛋白中的主要组分7S和11S蛋白，将木瓜蛋白酶分别作用于两种蛋白的溶液和不同7S/11S比例的蛋白溶液，结果表明11S蛋白是大豆蛋白中形成酶促凝胶的主要组分；7S蛋白形成凝胶所用的酶浓度高于11S蛋白所用的酶浓度，但11S蛋白形成的凝胶的弹性强度却远高于7S蛋白；在两种蛋白的混合溶液中11S蛋白的比例对凝胶的弹性强度起决定作用。
