The key device of instrument used to test vibration parameter about oil producing tech by physical method is down-hole memory tester, including control delay time device, pressure sensor, memory data box, digital to analog converting circuit, data-out device on the ground etc.

Clamping device is composed of a temperature-controlled micro-displacement driving device, an area effect stroke amplifier and a self-locking bi-bar single-acting toggle force amplifying mechanism.

And it is introduced the technical improvement method for the coagulating agent adding apparatuses, wastewater transporting devices, pressure devices and reflux releasing devices in the treating system and the applying effect.
