华庆油田白465井区长6、长8油藏产能递减规律分析

摘要

华庆油田白465井区长6、长8油藏自2010年12月产量开始递减，其中高含水和注采对应关系复杂是提升油藏产量的瓶颈。本文分析了油井高含水原因，进而控制油井含水上升速度，以及明确注采对应关系，充分发挥油井产能，提高储量动用程度，对提高区块整体开发效果都具有重要意义。%The production of Chang 6 and chang 8 reservoir in Bai 456 block of Huaqing oil field started to decline since December 2010,high water cut and the complicacy of injecting-producing relation is the bottleneck to increase production.This paper analyzed the reason of high water cut,control the water cut increases,clear injecting-producing relation ,give full play to well productivity and further more improve producing degree,which is significant meaningful for improving the development effect of the block.
