Software development for simulating real downhole casing deformation in Daqing Oilfields

Based on the brief introduction to the practice and research on the internal examination and verification in QHSE manage- ment system of Daqing Oilfields, several internal examining and verifying models are listed, with the comparative analysis of advan- tages and disadvantages of those models.

The test results of three dense well net regions in Daqing Oilfields indicate that sedimentary microfacies is the main factor influencing the planar distribution of residual oil.

EOR Technology Improvement and Its Further Development for Daqing Oil Field during "10th 5-Year-Project";

Accelerating Scientific Innovation and Making the Breakthrough of Techniques to Provide the Sustainable Development of Daqing Oil Field with Production Engineering Support;

Discussion on Two Problems in Well Testing Analysis in Daqing Oil Field;

The flooding efficiency of ASP combinational flooding solution of low alkaline(NaOH) concentration is studied experimentally under conditions of Daqing oil fields in reservoirs after water and polymer flood finished.

Four field trial projects on ASP flood completed at Daqing Oil Fields are introduced concisely.

In this review paper the methods and techniques for removing various precipitations plugged in raservoirs and for enhancing injectivity of water injection wells in Daqing Oil Fields are described briefly for their basic principles, characteristic features and proper uses.
