ABSTRACT OF THE DISCLOSURE A downhole tool testing apparatus has a modular construction including a pump assembly, a screen assembly, a first packer assembly, an intake port assembly, and a second packer assembly. The pump includes a discharge passage which is communicated with the first and second packer assemblies for inflating the same. The testing apparatus includes a flow passage therethrough communicating the intake port assembly with a pipe string to the lower end of which the testing apparatus is connected. A relief means is provided for com- municating the discharge passage of the pump with the flow passage of the testing apparatus and for thereby relieving fluid pressure from the first and second packer assemblies into the flow passage to deflate the first and second inflatable elements. The testing apparatus is utilized for testing sub- surface formations of a well. Further improvements are pro- vided in each of the pump assembly, screen assembly, first packer assembly, and intake port assembly.
