中文摘要:
      针对目前常用润滑剂荧光级别高、热稳定性差的缺点,研究了一种无荧光生物质润滑剂ZYRH的荧光级别、乳化稳定性、润滑性和抗温耐盐性能,并考察了ZYRH对钻井液流变及失水造壁性能的影响。研究结果表明,ZYRH荧光等级小于3级、乳化稳定性好、抗温达200℃、抗盐达饱和;基浆中加入1%ZYRH润滑剂后,极润滑系数降低率达91.5%~93.0%;生物毒性EC50值>1.0×106mg/L;与聚合物钻井液、聚磺钻井液、微泡钻井液等配伍性好。产品在卫455井、文23储气库等25口井进行现场应用,均取得良好效果,且产品对环境无污染。图5表4参14
英文摘要:
      A new fluorescent-free biomass lubricant ZYRH was developed to overcome the disadvantages of high fluorescence level and poor thermal stability of commonly used lubricants. The fluorescence grade,emulsifying stability,lubricity,temperature resistance and salt resistance of ZYRH were studied. The effects of ZYRH on the rheology and wall building properties of drilling fluid were investigated. The results showed that the ZYRH level was less than 3,the stability of emulsification was good,the tolerance to temperature was up to 200℃,and the salt resistance was saturated. After adding 1% ZYRH lubricant to the base pulp, the decrease rate of the extreme pressure lubrication coefficient was 91.5%—93%,the biological toxicity EC50>1×106 mg/L. ZYRH was compatible with polymer drilling fluid,polysulfonate drilling fluid and microbubble drilling fluid. ZYRH was applied in 25 wells,such as Wei 455 well and Wen 23 gas storage,and achieved good results,and the product had no pollution to the environment.
