Contradiction and countermeasure for chemical flooding in Shengli petroliferous province

The primary contradiction which limits the development of chemical flooding in Shengli petroliferous province is thoroughly analyzed on the basis of analyzing state of the art on chemical flooding technology, evaluating chemical flooding resources and tracing the implementation effect. In the long-term laboratory study and field tests, the theory of combination for improving polymer flooding effect is summarized, namely the "P+ N" theory. Temperature -resistant and salt -resisting/ polymer, organic combinatipn crosslinking system, en- hanced foam flooding and dibasic combination flooding are researched for solving the primary contradiction. These methods provide powerful technology support for the development of chemical flooding in Shengli petroliferous province and extend the applied field of chemical flooding technology.
