摘　　要：丰深1气藏属不带油环凝析气藏。储层低孔低渗,投产之前必须进行有效的储层改造。凝析油含量高,衰竭式开采凝析油损失严重,气井试采过程中表现的产量递减快、压力下降迅速等特征,反映出该井泄气范围有限。从产出的井流物变轻、生产气油比不断上升,以及地层渗流性能变差等方面看,目前地层中已出现了反凝析现象。根据评价研究。气井合理工作制度直径在4mm以内,井距不超过560m。Fengshen 1 natural gas reservoir belongs to a condense gas reservoir without oil loop whose porosity and permeability are low and which needed treatment before production. That a great content of condense oil makes a big loose for exploiting oil with manner of crocking up and the features of production decrease and pressure when testing for gas well reflect that the gas leakage scope is limit. According to being light of flow materials, raising up of producing oil to gas ratio and being bad of formation percolation capacity, the phenomena of reverse condense gas appears at present. Based on study of it, reasonable work system is in 4mm in gas well, well dis- tance is within 560 m and is not suit for development with manner of crocking up.
