坨17井试井资料分析与解释

双坨子气田坨17井于1998年7月10日完井，到目前为止共进行了1次不稳定试井，1次修正等时试井。利用产能试井、压力恢复试井资料的解释获得了大量信息，采用双对数和半对数对该井外边界进行分析，提出在进行试井解释时，解释模型选用十分重要，一定要结合地质条件和试井曲线形态进行判断。利用该井修正等时试井资料确定真表皮系数为0，而压力恢复试井解释的S为34，说明该井配产太高紊流损失严重。确定产能试井无阻流量为108．582dam^3／d，用无阻流量的1／5确定合理产量为21．7dam^3／d。

Analysis and Interpretation of Well Testing Data of Well Tuo 17

The Well Tuo 17 in Shuangtuozi gas field was completed on July 10th 1998.So far an unstable well testing and a modified isochronol testing were conducted.A great deal of information was obtained by interpretation of productivity test and pressure build-up test data.Based on double-log and semi-log analysis,the outer boundaries of this well are two parallel faults,which are corresponding with the geological conditions.It is presented that the selection of the interpretation model is very important for well testing interpretation.A correct judgment should be made by combining geological conditions and curve morphology of well testing.The true skin factor is determined to be about 0 by using modified isochronol testing of this well,however,the interpretation result of pressure build-up test shows that the production quota is too high and the turbulent loss is serious.The open flow capacity of productivity test is determined to be 108.582 thousand cubic meters per day,and the reasonable production is determined to be 21.7 thousand cubic meters per day by using one fifth of open flow capacity.
