摘要
长庆气田储层非均质性强,气层薄而多,单层产能较低,开采难度大,降低成本是气田经济有效开发的必由之路。文章介绍了长庆气田气井多层分压合采工艺技术,提出了探井、开发评价井及开发井的分压合采工艺。现场应用表明:气井分压合采工艺技术对于开发长庆多层系气藏,提高气田整体开发水平和经济效益具有重要的作用。
Because of the strong heterogeneity, multiple and thin gas-bearing layers, low single-layer productivity and extremely difficult exploitation conditions of the reservoirs in Changqing Gas Field, it is the only way for developing economically and effectively the gas fields to decrease cost. The multi-zone separate pressure production technology used for the gas wells in Changqing Gas Field is introduced and the separate pressure production technology used for exploration wells, development evaluation wells and development wells was put forward respectively in the paper. The on-site application results indicated that it was very important for developing the multi-zone gas reservoirs in Changqing Gas Field and raising the integral development level and economic benefit of the gas fields to adopt the technology.
