摘要
奥陶系碳酸盐岩缝洞型油藏为带底水的油气藏,油井见水主要是底水在裂缝系统内沿裂缝锥进井筒所致,含水快速上升,而各个单井的压力系统不一样,储层发育模式不一样,导致碳酸盐岩堵水无规律可循,堵水难度大。灰岩油藏比重法堵水新技术的研究与应用在塔河油田碳酸盐岩堵水取得了显著的效果,为塔河油田油井堵水控水提供了新的思路。
Abstract
Water was found at the bottom of the Ordovician carbonate fractured and vuggy reservoirs.The bottom water migrated along fractures into wellbore,resulting in well water.Water content rapidlyincreased,and pressure system and reservoir generation model varied between different wells,hencethere was no regularity for water plugging in carbonate rocks.A new proportion plugging technologywas developed and applied in carbonate reservoirs of the Tahe Oil Field,providing new ideas for watercontrolling and plugging in the study area.
