摘要
Abstract
Oil-in-water emulsion drilling fluid is an important low-density water base drilling fluid and is widely used in drilling low-pressure reservoirs.To enhance the high temperature stability of the oil-in-water emulsion drilling fluid in deep well drilling,a sulfonated betaine with varied carbon chains was synthesized in laboratory and used in formulating emulsion drilling fluid after measuringthe change of its surface characteristics.Experimental results showed that the drilling fluid formulated had excellent rheology and good emulsion stability.After hot rolling at 180-210 ℃ for 16 hours,the viscosity and gel strengths of the drilling fluid were maintained in reasonable ranges.HTHP filter loss was less than 20 mL,satisfying the basic requirements as an emulsion drilling fluid.No oil separation and emulsification were found of the drilling fluid.The drilling fluid was resistant to contamination caused by 15％ water,15％ diesel oil,15％ drilled cuttings,or by 2％ salt,respectively,indicating that it was able to satisfy the needs for deep low pressure reservoir drilling.关键词
