【摘要】 合成基钻井液在深水钻井中应用非常普遍。针对线性α-烯烃基液,研究了乳化剂种类、油水比、有机土加量等因素对钻井液性能的影响,在此基础上优选出了一种合成基钻井液配方,即:油水乳状液+3%有机土+4%乳化剂E+0.5%润湿剂+3%降滤失剂,水相的体积分数不超过30%。对比分析了线性α-烯烃、白油和气制油基油包水钻井液性能,结果表明,线性α-烯烃合成基钻井液具有更好的低温流动性,更适宜于深水钻井。更多还原

【Abstract】 Based on the analyses of influence of emulsifier,oil/water ratio and organic clay volume,formula ofsynthetic drilling fluid is given:emulsion fluid,3%organic clay,4%emulsifier E,0.5%wetter,3%filter reducer(water phase<30%(v/v)).Compared with white oil and GTL drilling fluid,linear a-alkene synthetic drilling fluidshows better fluidity in low temperature which is more appropriate for drilling operation in deep water.更多还原
