Optimization and control for completion pressure system and cementing technology of adjustment wells;

Formation pressure prediction method for adjustment wells;

Study and application of adjustment well cementing in Baise Oilfield;

Study on pattern modification of low Permeability reservoir for improving recovery factor;

In consideration of its characteristics, different measures are taken for well pattern adjustment and tapping the potential at different production stages.

Through integral well pattern adjustment, the producing level of waterflooding is raised in the reservoirs of category I and II, with 12% of waterflooding producing level increase, 5.

The traditional well pattern adjustment technologies such as infill drilling and subdivision of series of strata are not suitable in the circumstances.

Influence factors and countermeasure of cementing quality of adjustment wells in Henan Oil Region;

Optimization and Usage of Antichannelling Cement Slurries for Cementing Adjustment Wells;

The authors have analyzed the problems and difficulties in cementing technology of adjustment wells in Daqing Oilfield, introduced the development status and expatiated on the application of basic cementing theory, geological prediction and control technique, cement and additives, cementing tools in adjustment wells, while putting forward the research target of cementing technology.
