摘要
阿姆河右岸B区中部气田储层类型多样,产能差异大,通过动态资料总结出5类储渗类型。其中第一、第二类储层自然产能高,地层能量相对充足,具备高产稳产的潜力;第三、第四类储层具有较好的初期产能,但呈现出一定的递减趋势,稳产能力受限于单井控制储量或基质孔隙的供给能力;第五类储层相对较差,常规酸化基本没有效果,目前暂不考虑动用。部署大斜度井、实施储层改造是B区中部大幅度提高气田产能行之有效的手段。
In B region central gasfield, the right bank of the Amu Darya, the reservoirs have various types and a big difference occurs among their deliverability. It is found after the analysis of dynamic data that there are five types. For I- and II-type reservoirs, the natural deliverability is high and the formation energy is relative abundant, resulting in a potential of high yield and stable production. For III- and IV-type reservoirs, the deliverability during early stage is better; after that, a decline trend appears; their stable-production capacity is affected by controlled reserves of single well and supplement of matrix pore. No effect is for V-type res-ervoir with poor quality even though acid fracturing. So, the most effective means to increase deliverability of B region central gasfield include deployment of highly deviated well and fulfillment of reservoir reform.
