Research On Construction Technology And Application Of Oxygen Activation Logging Technology

To enhance the oil exploit-efficiency, a lot of the oil fields are widely used to flooding oil recovery technology,such as injected water, hot steam or chemical polymers to the oil reservoir now.In order to know the direction of the infusion for guiding the oil fields to formulate reasonable injection-production relationship, they need injection profile logging.They used production logging to monitor injection profile, understand the formation suction ability,the way is powerful technical to improve and enhance the efficiency of the injection-production.As the injection medium from water to the polymer, the ternary compound and the CDG gel, conventional injection profile logging technologies have their respective problems.In order to overcome the problems of the conventional logging methods, we have adopted a new logging technology- pulse neutron oxygen activation logging technology.This article carry out a series of technical researches to solve the various problems that pulsed neutron oxygen activation logging tool occurred in the logging process. Base on analyzing the technical limitations of original oxygen activation tool, we develope a new type of oxygen activation logging that is extensive application and high efficiency.According to the different blocks of the geological characteristics and development status of injection and production in the oil field, we summarized construction technology for the different types of injection well and gas-lift production well.Based on the actual logging experience, we made in-depth study and discussion for preliminary evaluation method of the logging data.
