The Research Of Tracking And Evaluating For Deep Profile Control Of M Layer In Lao Jun Miao Oil Field

In-depth profile control using weak gel is a significant technique of improving flood development in oil field. Although people have done much of research on laboratory and field experiment, there is no comparatively consummate theory system for guiding field scheme and following evaluation at present. Lao Jun Miao M layer is a low permeability and fracture-pore reservoir, flood water along high permeability layer or fracture in the intermediary and later stage of water drive, with quick water cut raising and declining production because of serious aeolotropism of reservoir. The research of flowing gel for deep profile control in the reservoir has been developed to improve the water flooding result and the testing area has been found about it. For the sake of guiding implement process and evaluating implement result, the research of tracking and evaluating for deep profile control of M layer in Lao Jun Miao Oil Field in this paper. First of all, numerical algorithm of mathematical model for deep profile control was improved. Secondly, the system of prediction and evaluation for deep profile control was established, and the software for it was edited. Based on them and with the conduct of scheme of flowing gel flooding in test area, the research of evaluating the present result and tracking simulating implement process has been done, and then pointing out affecting factors for profile control, and finally proposing adjusted scheme. The result indicate that the theory of prediction and evaluation for deep profile control and correspondent software meet the content of tracking and evaluating for flowing gel flooding of oil field better. Moreover, the means of tracking and evaluating for flowing gel flooding aimed at Lao Jun Miao oil field has the scientifically directive sense to other oil field.
