摘要

摘要: 由于中国存在大量的低压、易漏油气井，目前超低密度水泥浆体系在固井中的应用日益增多。由于减轻材料的密度小、抗破碎性能有差异以及超低密度水泥浆体系固液相的密度比低等原因，运用常规水泥浆体系的设计标准、实验方法、混浆操作会产生错误和问题，影响水泥浆性能的稳定，因此需要根据减轻材料的物性以及水泥浆设计密度对超低密度水泥浆体系现场试验及混浆方案做出针对性改善。从减轻材料、液固比、井下环境、抗压强度实验、水泥浆质量、混灰和转运过程以及现场混浆等方面，对超低密度水泥浆体系应用中出现的问题进行了探究，并分别提出了微珠的选择标准、液固比的最优窗口、井下环境的校正、强度实验方法的选择、水泥浆性能的控制、干灰质量保障措施以及LVF动态混浆系统等相关建议，对提高超低密度水泥浆体系固井作业的成功率有指导意义。

Abstract: Many oil and gas wells in China are cemented with ultra-low-density cement slurries because these wells penetrated lowpressure and easy-to-leak formations. Design criteria, test methods and slurry mixing procedure for cement slurries of normal density can not be used in operation with ultra-low-density cement slurries because of the low density of the light-weight materials, difference in breaking resistance of different materials and low density ratio of the solid phase and liquid phase in the ultra-low-density cement slurry. All these factors negatively affect the property stability of the cement slurry. Thus, improvement should be made to the program of field testing the ultra-low-density cement slurry and the program of mixing cement slurry based on the physical properties of the light-weight materials and the designed density of the cement slurry. To investigate the problems encountered in using ultra-lowdensity cement slurry, laboratory studies were conducted from several aspects, such as light-weight material, ratio of liquid to solid, downhole condition, compressive strength experiment, quality of cement slurry, cement mixing and field mixing of cement slurry etc. Suggestions have been provided regarding the selection of microspheres, optimum window of liquid-solid ratio, correction of downhole environment, selection of strength experiment method, control of cement slurry properties, quality assurance of the dry cement and LVF dynamic slurry mixing system etc. These suggestions are of instructive significance for the increase of the success rate of cementing wells with ultra-low-density cement slurries.
