Abstract:

An organic chrome crosslinking agent of weak gel for deep profile control has been synthesized by using a monose compound as ligand based on its complexing constant of the complexing agent. Results indicate that the crosslinking system has the properties of convenient operation, easy injection and good performance. The contraction between the vertical and plane in formation has been solved effectively and the oil recovery has been enhanced.

Key words: weak gel, profile control, cross linking agent, enhanced oil recovery
