胜利油田东营地区浅气藏排水采气工艺技术研究

Techniques for Gas Expulsion and Production in Shallow Gas Reservoirs of Dongying Area in Shengli Oilfield

出液井由于受到比采气指数、生产压差、采气工艺限制等影响,井筒积液不能及时有效地排出,严重时储层水淹,气井停产,严重制约了生产任务的完成和最终采收率的提高。从该地区的地质特征和现场开采工艺技术入手,结合理论知识和生产实践的经验,分析了地层、气井出液的原因,提出了适用的排水采气方法。应用表明该这些方法是有效的。

In fluid producing wells influenced by the constrain of specific gas producing factor,production pressure differential and production process,wellbore fluid loading can not be eliminated in time,reservoirs are watered out, production of gas wells are stopped as it is severely caused.Study is carried out on the geologic characters and production process,the cause for fluid production in the gas wells and in the formation are analyzed and the methods are proposed for water drainage and gas production in combination with theoretical knowledge and practice experiences.Application shows the methods are effective.
