PARKER APPARATUS ON CABLE AND OIL AND GAS WELLS HYDRODYNAMIC RESEARCH AND SAMPLING METHOD Russian patent published in 2010 - IPC E21B49/00 

FIELD: oil-and-gas industry.

SUBSTANCE: apparatus equipped with a pump (3), a sampler (6) wit a differential piston (7), samplers (13), a pressure controller (29, 30), located over and under a parker module and the pressure controller (31), located in a vertical channel (19), in which additionally located a receptivity metre (32), a drymetre (33), temperature controller (34). A parkering hermiticity defines with over and under parker pressure control, perform reservoir fluid injection a few times, measuring pressure and temperature, define water and hydrocarbons content of the pumped fluid from a separated reservoir space in a between parker zone. According to the temperature and pressure measurements draw a conclusion about reservoir fluids moving dynamics in a well, and according to the reservoir water content measurements and hydrocarbon content draw a conclusion about reservoir fluids samples content. At the presented factors positive dynamics sample in to the sample collectors.

EFFECT: device operation reliability increase, high quality reservoir fluids sampling.
