文 2 3气田经过长达 3年的压裂整体改造研究和现场实施 ,取得了明显的地质效果和经济效益 ,形成了适合中原油田块状气田压裂的配套技术 ;文章针对文 2 3气田的整体改造方案和开采现状 ,开展了整体改造的配套技术研究 ,成功地应用在整体压裂改造上 ,并对压后的效果从工艺、地质和经济效益上进行评价 。

Through the research and application of overall fracturing reformation of Wen 23 gas field for three years,an obvious geological for three years,an obvious geological effect and economic benefits have been obtained,forming a complete technique suitable for fracturing the massive gas reservoirs of Zhongyuan oil field.In the lighs of the overall reformation plan for Wen 23 gas field and the present producing situation of the field,the study of the technique necessary for overall reformation was carried out and the technique was successfully applied to the overall fracturing reformation.In this paper,the effect after fracturing is evaluated from technology and geology to economic benefits and the direction of the work in the next stage is put forward.
