榆林气田陕209井富水区开发技术研究

榆林气田主要产层为山西组的山2~3,小层,构造为东高西低的单斜构造。陕209井区普遍出现气水层和水层,试气过程中个别井气水同产,生产过程中气藏边部靠近水体的几口生产井不同程度地产地层水,个别井出水量大,严重影响了气井产能,对整个气田的高效开发不利。研究着重于在气藏水体分布规律和气水同产井开发动态分析的基础上,采用多种方法,对有水气藏的配产和水侵特征进行研究分析,为有水气藏出水综合治理和开发提供科学依据。

Study technological development rich water area of the yulin gasfield shan zopweil

The yulin gas field mainly produces the layer as the mountain set 2~3 small layers,structure for east high west the low list is inclined to construct.The area of shan 209 well widespread emergence the gas and water layer,try the gas process to produce together in the individual well gas and water.In the production line the gas hides of the side department closes to the water body of a few production wells different degree real estate geologic strata water, the individual well the water have great capacity,influencing the productivity of gas well seriously,to whole annoy gas field develop disadvantage efficiently.This research puts great emphasis on annoying the water body to distribute regulation,friendly water producing analytical foundation of the well development dynamic state together,adopting various methods,going together with produce and invade characteristic to carry on the research analysis with water towards having the water and gas hide,for the water and gas hide have a water to synthesize and development manage to provide science the basis.
