针对元坝气田地层测试资料未出现径向流多的问题,由于实测数据不符合目前的试井基础理论与解释方法,研究和应用了新型的试井解释技术-压力速率解释技术。与常规技术相比较,摆脱了传统软件以径向流分析条件的制约。在元坝气田的实际应用效果表明,该技术能很好地解决未出现径向流疑难试井问题,为元坝复杂气田措施改造和综合评价提供了依据。
In view of the fact that there is no radial flow in the formation test data of the Yuanba gas field, a new interpretation technology of well testing, pressure rate interpretation, has been researched and applied due to the fact that the measured data do not accord with the current well basic theory and interpretation method. Compared with the conventional technology, the traditional software is free from the restriction of radial flow analysis conditions. The practical application results in the Yuanba gas field show that this technology can well solve the problem of difficult-to-well test in the radial flow and provide the basis for the transformation and comprehensive evaluation of the measures of the Yuanba complex gas field.
