摘要
双坨子气田是目前吉林油田天然气开发的主力区块 ,正处于开发实验阶段。通过对双坨子气田地质特征的研究 ,结合气田试采动态资料 ,分析了气藏试采动态特征 ,初步认为 :白垩系泉头组三段以上气藏为小型中低产中低渗岩性构造气藏 ,泉一段、侏罗系气藏为中型中丰度低渗透中产中深常压原生凝析气藏 ;中深部气井产量稳定 ,产气量相对较高 ;浅层气井日产气量相对低于深部气井 ,日产水量较大 ,生产压差大 ;下游用户用气量波动影响较大。同时 ,利用产能试井测试资料和实际生产数据 ,应用经验法、单井产量法、单位压降法和流入流出曲线法综合分析了单井产能 ,从而确定了双坨子气田整体年产气 1.4 5× 10 8m3 的能力 ,年采气速度为 2 .3% ,为双坨子气田的有效开发提供了依据。
Shuangtuozi Gas Field is the main block for gas production in Jilin oil field,and locating in the testing stage now. With the study on the geological features of Shuangtuozi gas field and the performance data of production test,the performance characteristics of production test of the gas reservoir are analyzed. It is identified that the gas reservoirs above the third section of Quantou group of Cretaceous are small structural gas reservoirs with medium and low permeability and production. The gas reservoirs in Quan Section 1 and Jurassic are original condensate gas reservoirs with medium richness,low permeability,medium depth,and normal pressure. The productions of meddle and deep wells are stable and high. The shallow gas wells have lower production than the deep wells,and have large water production. Their producing pressure difference is big,which causes gas transmission fluctuating for down-stream customers. Also,using the production testing data and real production data,applying experience analogy method,single well output evaluation method,units pressure-drop evaluation method and inflow and outflow curve evaluation method,the single well productivity is analyzed. And it is determined that the ability of annual output is 145 MCM,and the annual gas recovery rate is 2.3% in Shuangtuozi gas field,which provides the ground for effective development of Shuangtuozi gas field.
