在气田的开发历程中 ,试采处于基础阶段 ,搞好气田的试采工作就是打好基础。大天池气田有探明储量 12 0 0× 10 8m3 以上 ,可采储量 90 0× 10 8m3 以上 ,有气井 5 2口 ,井口产能 75 0× 10 4 m3 /d以上。大天池整装气田已投产三个 :五百梯、龙门、沙坪场 ,总结大天池气田从 1992～ 2 0 0 1年共 8年多的试采情况 ,主要有认真编制并严格执行试采方案 ;选择有利气井作为激动井 ;分阶段进行试采 ;搞好全气藏关井及稳定试井 ;产出流体性质及井口压力加密监测 ;运用先进测试技术及仪器参与试采 ;见干扰 1口井投产 1口井 ;新井投产时进行稳定试井 ;试采成果作为部署开发井依据等试采技术。同时对这些试采技术的综合效果进行分析总结 ,并建议在今后的新气田试采中 ,应用这几项技术 ,有利于缩短试采期 ,降低气田开发成本 ,为企业创造了最佳的经济效益。

Production Test Techniques Used for Integral Datianchi Gas Field in East Sichuan and Their Effectiveness Analysis

??In the process of gas field development,the production test is in its basic stage and a successful production test will lay a good foundation for the future gas field development work.There are proved reserves of more than 120×10⁹m³,recoverable reserves of over 90×10⁹m³,52 gas wells,and well-head deliverability of above 7.5×10⁶m³ in Datianchi gas field.Three highs,i.e.Wubaiti high,Longmen high and Shapingba high,in the gas field have been put into production.Through summarizing the production test circumstances in more than eight years(1992??2001)in the gas field,the following techniques have been applied:carefully compiling and strictly executing production test plan;taking beneficial gas wells as the active wells;carrying out production test by stages;making a good job of closing all the wells in the gas reservoir and of systematic well testing;closely monitoring produced fluid properties and well-head pressures;doing production test by use of advanced testing techniques and devices;putting the interference well into production as soon as possible;making systematic well testing before a new well's being put into production;and taking the production test results as the basis of disposing development wells,etc.Meanwhile,through analyzing and summarizing the comprehensive effectiveness of these techniques,it is suggested that the application of these techniques in the future production tests in the novel gas fields is beneficial to shortening production test time and reducing gas field development cost,thus creating optimal economic returns for the enterprise.
