Application of Horizontal Well Production Profile Logging Technology

The optimum length of the horizontal section should be designed based on the reservoir types, valuable formation and well spacing patterns. To put the logging tool smoothly into horizontally drilled formation, two techniques for production logging have been developed. One is the flexible tubing (u-sually consecutive oil tube) conveying approach, the other is the downhole towing conveying approach. Introduced is the used logging series. The solution for oil, water and gas phase (called as three-phase flows) separation is given. Horizontal well logging data interpretation and evaeluation are determined; flow logging response relation and fluid holdup relation are derived. Through simulation experiments, four fluid types are determined; flow logging response relation and fluid holdup relation are derived. Some logging examples proved that the two techniques are useful in horizontal well production profile logging operations.
