Identify Interlayer Insulation by Using Logging Data

摘要

Interlayer insulation of the reservoir is one of the important factors on influencing fluids in the reservoir. From observation and identification of coring well, the interlayer insulation of the reservoir in Xinli oilfield can be divided into three categories: Argillaceous interlayer, Calcium interlayer and Physical interlayer. study the method of using logging data to identify interlayer insulation. Through different types of logging response characteristics of interlayer insulation analysis and comparison, the region of interlayer identification standard is established. Good results have been achieved in the recognition of single well longitudinal sandwich insulation, a train of thought for every identification of interlayer, at the same time, laying the foundation for middle and surplus oil distribution and the development plan.
