Analytic Method on the Quality of Microbial Enhanced Oil Recovery Based on Fuzzy-AHP

“…There need to construct 7 priority relation matrix totally here , A-B , B1-C , B2-C , C1-F , C2-F , C3-F , C4-F , considering the judgment results of several experts synthetically, We construct the number of the matrix as follows : Correlation threshold is set 0.7, so that an important source of microbial quality 3,2 and 11 for the event. This result is consistent with the reference [6] cited by the U.S. oil and energy, the proposed screening criteria microbial enhanced oil recovery reservoir. Under 50℃ the high glial oil viscosity reduced 22.2%, Lower the freezing point of high wax 2.5℃.…”

Preparation and Evaluation of Controlled Expansion of the Sealing Agent KP

“…Absorbent resin is a new class of polymer plugging materials developed in recent years, the water swelling with certain viscoelastic gel, with a certain intensity, strong water retention, salt and stability [1]. Resin absorbent material can be used for the drilling, plugging the key is to control and adjust their water absorption rate, while the absorbent resin absorbent faster, and the water speed is difficult to control [2].…”
