高升油田低速区块储层伤害机理及原因分析

Analysis of the Reservoir Damage Mechanism and Reasons for the Low-speed Block of Gaosheng Oilfield

针对高升油田难动用区块开发过程中存在的蒸汽吞吐注汽困难,蒸汽吞吐效果差;措施效果差,油井产能低,区块始终处于低速开发等问题,以储层油藏特征研究为突破口,对储层敏感性进行了深入分析,并找出了影响高升油田难动用储量低速开发的根本原因,为今后的酸化解堵、降压注汽和储层保护提供了可靠的依据和方向。

In terms of the existing difficulty of steam huff and puff and gas injection,bad steam huff and puff effect,bad measures effect,low capacity of oil well and low-speed development of block all the time etc.problems in the development process of difficult-to-utilize block of Gaosheng oilfield,besides,found the primary reason influencing the low-speed development of difficult-to-utilize reservoir of Gaosheng oilfield,which has provided reliable basis and direction for future acidizing plugging removal,reservoir protection,depressurization and gas injection.
