Expanded application study on pulsed neutron logging technology in Huabei Oilfield

In order to give full play of pulsed neutron logging technology in the role of dynamic monitoring in oil field development and expand its application range better, the technical research and introduction work were continuously conducted. Firstly, in order to seek a more in-depth and accurate solution to specific technical problems as well as open up new geological application areas, the logging methods and data were further discussed and researched. Secondly, new pulse neutron logging methods and instruments were actively developed, introduced and expanded. Meanwhile, a continued and long-term commitment was made to support the technical co-ordination work of a variety of production logging technologies. These work made sure the dynamic monitoring being solved more fully and effectively. The carrying out of all work above made application effect of pulsed neutron logging more significant and applying area further extended in Huabei Oilfield which resulted in good oil field development and economic benefits. Innovation and expanding application study greatly promoted the updating and improvement of pulsed neutron logging technology. Thus, the increased consistent rate of comprehensive interpretation came to about 9%. The increased annual cumulative logging work was more than 25%, and the amount of data using for water transfer and oil increasing gained a substantial strengthening. In an important aspect, the develop program of the new type of pulsed neutron logging technology also pointed out the direction for reservoir dynamic monitoring in Huabei Oilfield.
