间断性非稳定流抽水试验求参问题的研究

PARAMETERS DETERMINATION OF DISCONTINUOUS NON-STAEDY PUMPING TESTS

在抽水试验过程中,常因突然停电,设备故障等而导致试验间断,此类问题普遍存在,其求参尚无适当的方法和公式可循。本文充分考虑到实际抽水过程与抽水间断的影响,根据势函迭加原理对泰斯型含水层的单孔、多孔、群孔间断性抽水试验的求参问题均进行了研究,推导出相应的一系列公式与求参方法,此类公式具有普遍性理论意义和实用价值,可视为相应的无间断抽水求参公式的拓广形式。

Pumping tests are frequently interrupted by some reasons such as electricity cut, equipment failures, etc. The problems exist widely, but no suitable methods and equations of parameters determination for them can be followed so far, The author has researched the discontinuous non-steady pumping tests for simple well and multiple wells of Theis type aquifers based on the superposition theory of potential function, and put forward a series of equations and methods of determining parameters, which have been used to a lot of field practice and good results have been obtained. The research shows that the equations are of universal theoretical significance and practical value.
