为提高疫甲基轻乙基纤维素（CMHEC）溶液的器弹性，暂宽其应用范围，以环氧氢丙烷（EPIC）与CMHEC 摘要
进竹反应，首次制备出求落性改性度甲基轻乙基舒推素EPIC-CMHEC，研光了EPIC-CMHEC和CMHEC水溶痛的流变待性（流动曲线、黏弹性、本构方程、愈变性等）以及减限性能。结采表明，EPIC-CMHEC溶液熟度显著提高，其3g/L 水溶液黏度为56.6mPas，比3g/LCMHEC水游液的度（18.3mPa*s）提高了2.1带，且弹性也优于CMHEC溶液。连170s 剪切下，温度从20C升至80C后，0.3%EPIC-CMIIEC净液的粘度约为19mPa·s，仍高于25C时0.3%的CMHEC溶液的粘度；EPIC-CMHEC溶液的减阻性能电旁显提高，0.10%的EPIC-CMHEC和CMHEC溶液最大减阻率分别为72.70%和 68.41%。EPIC-CMHEC和CMHEC溶液的流动曲统可用Cros本构方准速行表任，EPIC-CMHEC可望用于油气田开采和减阻领域。

Langfang Branch of PetroChina Research Institution of Petroleum Exploration and Development, Langfang, Hebei 065007) Abstract To improve the viscoelasticity of carboxymethyl hydroxyethyl cellulose (CMHEC) solution to widen its ficld of application, a water soluble EPIC-CMHEC has been developed by reacting epoxychloropropane (EPIC) with CMHEC. EPIC-CMHEC and CMHEC water solutions were studied for their rheology (fow curve, viscoelasticity, constitutive equation,and thixotropy etc.)and drag reducing performance. The study has shown that compared with that of the CMHEC solution, the viscosity of the EPIC-CMHEC solution was notably increased. Water solution of 3 g/L EPIC-CMHEC had viscosity of 56.6 mPa · s, 2.1 times of the viscosity of a 3 g/L CMHEC solution (18.3 mPa · s), and the elasticity of the EPIC-CMHEC solution was better than that of the CMHEC solution. Sheared at 170 s', when temperature was increased from 20 C to 80 °C, the viscosity of 0.3% EPIC-CMHEC solution was 19 mPa * s, still higher than the viscosity of a 0.3% CMHEC solution at 25 °C. EPIC-CMHEC solution had better drag reducing performance. The maximum percentages of drag reduction of 0.10% EPIC-CMHEC solution and CMHEC solution were 72.70% and 68.41%, respectively. The flow curves of the EPIC-CMHEC solution and the CMHEC solution can be expressed with cross constitutive equation. EPIC-CMHEC is expected to find its use in oil/gas development and where drag reducing is required.
