摘　　要：对延长特低渗气田的试气工艺进行浅析,选取盒8段和山西组山1段,山2段,本溪和太原组作为典型的试气井区,从试气选井、通井、试压、射孔、放喷和测井等方面进行试气研究,同时,再对压裂工艺和数据采集系统进行补充。利用＂一点法＂测井工艺进行做出无阻流量公式,校对后公式计算无阻流量和延长现用无阻流量计算结果误差在0.9%-5.6%范围之内,最后完成延长特低渗气田的试气研究。The process of gas testing in extra low permeability gas field was analyzed,the He8 and Shanxi groups of Shan1,Shan2,BENXI and TAIYUAN as the typical test gas wells were selected,from the test gas wells,wells,pressure test,perforation,discharge and logging and other aspects,the test gas was studied. At the same time,the fracturing technology and data acquisition system were added. The ＂one point method＂was used to make logging technology flow formula,checked after formula flow and extended the current calculation results of AOF,error was in the range of0. 9% ~ 5. 6%,gas field test study on extended ultra-low permeability was finally completed.
