ABSTRACT:
A well fluid sampling apparatus for sampling fluids from a formation reservoir in a wall. The sampling apparatus comprises a body portion defining a large sampling chamber therein and at least one sampler module disposed in the sampling chamber. The sampler module is adapted for separately entrapping a volume of fluid as the sampling chamber fills. A sliding sampler valve is moved to open a sampler port allowing formation fluid to enter the sampling chamber. The sampler module has a metering piston therein which automatically closes after a predetermined volume of fluid has entered a sampler module chamber defined in the sampler module. The metering is accomplished by a chamber filled with a viscous liquid which must be discharged through a small orifice as the piston moves in response to fluid pressure in the sampling chamber. The viscous fluid is discharged into an air chamber. Testing gauges may be positioned adjacent each of the sampler modules to measure and record fluid pressure and temperature as desired. A surface drain nipple may be connected to a portion of the sampler module for moving the metering piston to an open position for draining the fluid from the sampler module chamber. A drain collar and drain nipple may be attached to the sampler module adjacent the hole therein for draining through a drain line and appropriate valving. The sampling apparatus may be used as a portion of a perforate, test and sample tool which also includes a packer and perforating guns. No portion of the fluid entrapped in the sampler goes above the packer or enters the tool string.
