摘　　要：海上水平井开采具有高含水、高液量、高速开发的特点,高含水水平井治理难度大、效果难保证。本文在采用爬行器输送、PLT和MAPS组合测试技术找准出水位置基础上,利用过筛管定向堵水分段控采技术实现了出水层段的有效封堵,取得了显著的控水增油效果。该研究为水平井治理提供参考,具有广阔的应用前景。There are the characteristics of high water cut,high liquid,and high speed development for offshore horizontal well.It is difficult for horizontal wells with high water cut to control water and increase oil,and there is large uncertainty for treatment result.Based on the result of water detection using the combined well logging technology of PLT and MAPS powered by tractors,the application of the directional water shutoff bypass screen and segmental control production technology realized the effective plugging of the water outlet interval,and reached the significant result of water control and oil increase.This research not only provides some references for horizontal well treatment,but also has broad application prospects.
