宁夏气田气藏生产特征及稳产技术对策探索

Exploration on production characteristics and stable production technology of gas reservoirs in Ningxia gasfield

宁夏气田经过近5年的规模勘探评价,已初步形成具有2000×108m3以上储量的整装大气田。作者从气藏地质特征出发,结合试气试采成果,利用PIPSIM气举设计软件,结合COMACO图片校正,制定合理的排水采气技术政策,以发挥气井的最大生产能力,实现宁夏气田的效益开发。文章对下步宁夏气田的产能建设、滚动开发和气井配产等工作的开展具有较强的实际指导意义。

A fully-equipped gasfield with reserves of more than 200 billion cubic meters in Ningxia gasfield has initially formed,after nearly five years of large-scale exploration and evaluation.A reasonable drainage gas recovery technology policy is formulated by using the PIPSIM gas-lift design software,combined with the geological characteristics of the gas reservoir,the results of gas test and production and COMACO picture correction,so that full use of the maximum production capacity of the gas well and profitable development is made.The paper has strong practical guiding significance for the development of production construction,rolling development and allocation of gas well in Ningxia gasfield.
