摘　　要：冀东油田南堡陆地断块油藏多采用水平井进行开采,在开发过程中水平井段易水窜、水淹,油井含水上升速度快,导致油井产能下降,严重影响油田的开发效果。需要对水平井产出剖面及其水淹状况进行测试,及时采取有效措施,降低油井含水,挖掘剩余油潜力,提高油井单井产量和最终采收率。为此,开展了牵引器输送测井仪气举法分段流量测试工艺对水平井进行产出剖面测试的技术探索。现场应用于4口高含水水平井中,都取得了完整的测试资料,为解决水平井高含水问题提供了很好的测试手段。Horizontal wells were often used for oil development in the onshore fault block reservoirs in Nanpu Area of Jidong Oilfield.During the horizontal well development,edge water and bottom water channeling,water-out were easily induced,water content was raised rapidly,by which oil productivity decrease was caused,and the effect of oil development was severely influenced.It was needed to test the producing profile and water-out conditions of horizontal wells to take effective measures in time,reduce the water content,tap the potential of residual oil and enhance oil production of single well and ultimate oil recovery.Therefore segment flow measurement technology was studied by using logging instrument carried by drawing device for testing the producing profile of horizontal wells.The technology is by used in 4 horizontal wells with high water-cut,and complete test data are achieved.It provides effective test meanings for solving problem of high water-cut in horizontal wells.
