Optimization and performance evaluation of completion fluid system for KF oilfield in Uganda
Based on the reservoir characteristics and the technical requirements for completion fluid for reser-voir protection in the KF oilfield in Uganda,the composition and performance evaluation of completion fluid systems were designed and carried out.Through optimizing the dosage of organic amine inhibitors and corro-sion and drainage aids,as well as studying the formulation of the completion fluid system,a set of organic amine completion fluid system had been formed,which mainly focused on the inhibition performance and com-bines waterproof locking and corrosion resistance.The formulation of the completion fluid system was water+ 1.5%(mass fraction)corrosion and drainage aid HZ-1+organic amine inhibitor YZ-1+10%(mass fraction)KCl.The experimental results showed that the anti expansion rate of the system reached 95.2%,with a surface tension of 27.2 mN/m,an interface tension of 2.04 mN/m,a corrosion rate of 0.047 mm/a,and a permeability recovery rate of over 85%for the reservoir.The formed completion fluid system can meet the technical require-ments of the completion stage of the KF oilfield in Uganda.
