丘东气田修正等时试井优化设计探讨

Probing into the Optimizing Design of Modified Isochronal Flow Test in Qiudong Gas Field.

丘东气田是低渗储层凝析气田 ,采用修正等时试井方法较为合理。经在温 1井、温 8 2 6井实施修正等时试井工艺 ,提出了气井修正等时试井的优化方案 ,包括等时间隔的选取、延时生产时间的确定、气井产量的确定、生产管径的影响、井筒容积的影响、压力计下深及施工过程的监测几方面 。

Qiudong gas field is the condensate gas field with low permeability reservoir,which is comparatively reasonable to adopt the modified isochronal flow test method.Having been used this technology at Wen 1 well,Wen 8 26 well,the optimizing design of gas well has been proposed that includes selecting time intervals,determining prolong production time,defining the gas production effect of production calibre,effect of well bore volume,depth of lowing gauge and monitor in the operation process.All of this provide a reference for the same kind of gas field production test.
