濮67块是埋藏深、低渗和难动用的凝析气藏,由于这些特点,目前气藏采出程度很低,开发效果差。文章通过对濮 67块天然气储量再认识,落实了该块储量;通过对濮 67块各砂组剩余天然气分布规律的研究,明确了剩余气的下步挖潜方向;开展了配套的剩余天然气挖潜技术研究,解决了该气藏的开发的技术难题,通过在生产中应用,取得了较好的增产效果,提高了气藏的采收率。

Pu 67 block is special condensate gas reservoirs,which feature buried deep depth,low permeabili-ty and difficult producing,At present,the recovery percent of reserves is very low,and the developing result is bad. Through study on the distribution law of remaining natural gas in Pu 67 block,the direction of further tapping production potential was determined for the remaining gas,the matching tapping production potential technology was studied to solve the problems in gas reservoirs development,which achieved better production increasing results in the field application.
