Abstract

Abstract: In order to increase the separate-layer water injection effect of heterogeneous sandstone reservoir in Huabei Oilfield, improve the qualified rate of water injection and reduce the workload of sealing, testing and adjustment, the wireline intelligent separate-layer water injection technology was used. This technology can remotely read the downhole water injection flow, temperature, pressure which was collected by the intelligent water distributor in real time on the ground. And it also can adjust the nozzle size of the intelligent water distributor in real time to make the sealing test and adjustment work easily. Up to now, there are 180 wells were implemented by wireline intelligent separate-layer water injection technology in Huabei Oilfield. This paper introduces the characteristics, key tools and construction auxiliary devices of the wireline intelligent separate-layer water injection technology. And it also evaluates the effect of the 33 wells which were implemented in the past year. The effective probability of 33 well groups is 92%, and that of corresponding wells is 83.8%. The cumulative oil increment is more than 277830 bbl and it has saved the cost of sealing test and adjustment work by 33.12 million yuan. The effect is remarkable on cost decreasing and benefit increasing. The wireline intelligent separate-layer water injection technology can improve the water flooding oil recovery effectively and it is helpful to the accurate development of oil reservoir. This technology has great value of application and popularization.
