DEVICE FOR EXTRACTING BED PRODUCT AT MOUTH OF PRODUCT WELL Russian patent published in 2005 - IPC

FIELD: oil industry.

SUBSTANCE: device has hollow cylindrical body, branch pipes for extraction and output of sample and locking element. Body is made thick-walled. End portions of body are made in form of truncated cone and interconnected, on the side of lesser bases by means of channel. Branch pipe for extraction of sample is made elongated, with length equal to body diameter, and is let through in transverse direction of body through the center of said channel. Within limits of branch pipe cross-section its hollow is separated by slanted solid wall on two portions, each of which is connected thereto. One portion of branch pipe hollow is meant for taking sample, other one - for feeding reagent into well product. To receive trustworthy information about sample, by setting flow to homogenous state, inner surface of cone, on the side of larger base, is provided with rigidly fixed blades for turbulization of flow flowing into body, while diameter of channel connecting cones is selected equal to diameters of their lesser bases.

EFFECT: simplified construction, broader functional capabilities, higher quality of sample.
