Research On Super-low Permeable Horizontal Well To Improve The Cementing Quality In Daqing Oil Field

Cementing horizontal well is an important part in the process of horizontal welldrilling and well completion, however due to the particularity of borehole trajectory,cementing operation to bring very great difficulty, and increases the risk of construction, makethe horizontal well’s cementing quality difficult to guarantee, directly affects the service lifeof oil and water Wells.This topic through the cementing technology of horizontal well inland and abroadcomprehensive research, which is a super-low permeable horizontal well cementing quality inDaQing oil field on the influence factors analysis, and targeted to carry out the relevanttechnical research and field test. Developed under the horizontal well casing string into theanalysis and prediction center optimization software and the horizontal friction on thecementing fluid numerical simulation analysis and optimization design software, analysisapplication floating casing technology, a new type of low viscosity and high cutting andaggravating flushing fluid system and the new zero drainage, low fluid loss, high stability, lowpermeability cement slurry system.
