在某些渗透系数低的潜水含水层中,大口径井的井径r_w不能概化为零,这就使其井流问题复杂化。本文推导了各向异性介质中大口径潜水完整井流公式,对于相应条件下的井流试验,文中推导的两个公式具有实用价值,在试验现场就可很方便地求出各向异性渗透系数K_x、K_y。 In some submarine aquifers with low permeability coefficients, the well bore radius r_w of large diameter wells cannot be generalized to zero, which complicates well flow problems. This paper deduces the complete well flow formula for large-diameter diving in anisotropic media. For well flow tests under corresponding conditions, the two formulas derived in this paper have practical value, and the anisotropic permeability coefficient can be easily obtained at the test site.
