大牛地气田泡沫排水工艺效果影响因素分析

Analysis the factors of affecting drainage of the bubble technology in The DaNiuDi Gas Field

大牛地气田是典型的低压、低产、低渗透气田,气田的开发需要借助泡沫排水工艺解决井筒积液造成的生产回压增大、井口压力下降、产气量下降等问题。在泡沫排水工艺应用中,常造成人力、物力、财力的浪费,为此有必要对影响泡排效果的因素进行分析,以提高泡排的成功率和经济效益。

The DaNiuDi Gas Field is a typical low--pressure, low--yield, low--permeability gas field. The development of this gas field needs the help of drainage of the bubble technology to resolve a series of problem led by the wellbore liquid loading , For example, Production back to pressure increasing, wellhead pressure drop, gas production declined, and so on. In the course of Application of the Drainage of the bubble technology, often caused human, material and financial resources to waste. To this end, it is necessary to analysis the factors of affecting drainage of the bubble technology, as so, we can improve the success rate of Drainage of the bubble technology and economic benefits.
