某井气举排水采气工艺设计

摘要

   气举是通过气举阀,从地面将高压气体注入停泵的井中,利用气体的能量举升井筒中液体,使井恢复生产能力。气举可分为连续气举和间歇气举两种方式。影响气举方式选择的因素有:井的产率、井底压力、产液指数、举升高度及注气压力等。对那些井底压力和产能高的井,通常采用连续气举生产;对那些产能及井底压力低的井,则采用间歇气举或活塞气举。
   气举排水采气技术是通过气举阀,从地面将高压天然气注入停喷的井中,利用气体的 能量逐级举升井筒中的液体,使井恢复生产能力。气举可分为连续气举和间歇气举两种方式。目前现场普遍采用连续气举的方式。2010年在建南构造建34井开展连续气举排水采气工艺试验, 取得了比较显著的成效。通过对现场试验情况进行分析,总结了连续气举排水采气工艺在建南气田气藏水侵治理中取得的成功经验。

ABSTRACT

  Gas lift gas lift valve from the ground, the high-pressure gas injection wells stop the pump, use of gas energy to lift the liquid in the wellbore, the well to restore production capacity. Continuous gas lift and intermittent gas lift gas lift can be divided into two ways. Factors affect gas lift options: the yield of the well bottom-hole pressure, fluid production index, lifting height and the gas injection pressure. Bottomhole pressure and high capacity wells, usually continuous gas lift production; intermittent gas lift or piston gas lift capacity and low bottomhole pressure wells.
  Gas lift drainage gas recovery by gas lift valve, from the ground to high-pressure gas injection stop injection wells, the gas energy gradually lift shaft in the liquid, the well production capacity. Gas lift can be divided into continuous gas lift and intermittent gas lift in two ways. The present continuous gas lift method commonly used in field. 2010 in Jiannan structure built 34 wells to carry out continuous gas lift drainage gas recovery technology test achieved remarkable results. Through the analysis of the field test, summed up the successful experience of continuous gas lift drainage gas recovery technology made in Jiannan Gas Field gas reservoir water influx in governance.
Keywords: The construction of 34 wells;  gas lift valve;  straight gaslift;  as well production with water withdrawal ;test.
