Temporary plugging and fracturing technology
application scope
1. New well fracturing:
Gradual temporary plugging and diversion fracturing - Grading the temporary plugging of each cluster hole.
Use temporary diversion plugs instead of fracturing drillable or soluble bridge plugs.
Full wellbore temporary plugging and diversion fracturing (one-time temporary plugging for long perforation sections).
2. Refracturing:
Horizontal well fracturing uses temporary plugging and diversion fracturing in stages and stages.
◎ Temporary blockage for scale removal, temporary blockage before acidification, temporary blockage after chemical treatment, etc.
Difficulty in fracturing due to casing damage, necking, and casing leakage.

technical characteristics
The core solution of the temporary plugging technology is "injectable, pluggable and unblockable".
technical advantage
After scientific theoretical research and years of construction experience, our company has developed a complete set of temporary plugging and fracturing solutions from chemicals to construction. From 2018 to 2021, our company has implemented 417 temporary plugging and fracturing projects in oil production plants in major oil fields, and the temporary plugging and fracturing package includes various formations such as Yan8, Long2, Long4+5, Long6, Long8, etc. The construction efficiency rate has reached 98.5% and the project The settlement rate reached 92%, and the accumulated oil increase exceeded 80,000 tons, which was well received by the customers. From 2012 to 2022, our company carried out more than 1,500 wells of repetitive fracturing and temporary plugging in the Ordos Basin and achieved good results.
