文23 气田是我国东部地区迄今投入开发的最大砂岩气田,其年产量占中原油田气层气产量的60 %左右。但文23 气田面临构造复杂、储层低孔低渗,具有边底水等问题。为此,从气田开发准备到目前开发稳产全过程,围绕地质基础研究、气藏工程研究、气层保护、动态监测、储层改造等方面,广泛应用国内外新技术和新方法加强对气田的综合研究,及时调整开发部署,使气田在已稳产10 a 的基础上可再稳产6 a ,实现了气田科学高效开发。

Wen 23 gasfield is the biggest sand gasfield ,which has been developed in the east of China. The output of the gasfield is 60 percent of the total output of gas reservoir in Zhongyuan Oilfield or so.Now the gasfield are faced with several questions , such as complex structure ,low porosity and low permeability ,fringe and basal water , etc. There are little experiences can be used in development in the world. So across the total production period , new techniques and new means are widely used in studying the gasfield comprehensively ,and justifying the developing disposition around the basic geology study , gas reservoir engineering research , gas information protection , dynamic supervision and testing, reservoir reforming , etc. . Thus Wen 23 gasfield will product steadily for another 6 years on the basis of 10 years’ stable production periods.Wen 23 gas field realize the aims that it can be developed highly efficient and scientifically.
