| Abstract: | A great number of testing studies were carried out for the research and application of light-weight high-strength slurry cementing technique-one of the set of techniques used for gas under-balance pressure drilling in well Shaan--242 in Changqing gas field and a light-weight high-strength slurry system including the lightening and reinforcing additives and high-temperature filtration-reducing agent was developed by the authors.On-site testing results indicated that the cementing job quality is satisfactory by applying such a system which can fully meet the demand of the under-balance pressure drilling for cementing slurry. |
