Application and Development of Boron-injected Neutron Lifetime Logging Technology in Huabei Oilfield.

Boron neutron lifetime logging technology developed recently is a new technology used to determine waterflooded status of development wells and analyze the proportion of interlayer oil and water. According to the log interpretation result, proper measures can be adopted for wells to reduce water production and/or raise oil offtake rate. In this paper, some case histories show good effects and developing prospect of the boron neutron lifetime logging technology in Huabei Oilfield. In the course of implementing the technology, the principle for well selection, boron injection parameters and the schema for logging and injection are continuously optimized. Meanwhile, comprehensive correlation interpretation is further stressed to improve the reasonableness, accuracy of the technology and coincidence of interpretation.
