The invention relates to the technical field of
oil field well drilling samplers, in particular to a
drilling fluid sampler with an anti-
sedimentation function for an
oil field. The technical problems that
deep drilling fluid cannot be sampled,
silt in the
drilling fluid in a water bucket can be precipitated and attached to the bottom and the wall of the water bucket after sampling, the
silt is inconvenient to be completely taken out of the water bucket, and the test and detection result is influenced during test and detection are solved. Comprising a third shell interior, a sampling mechanism and an anti-
settling mechanism; the sampling mechanism is fixedly connected to the upper portion in the third shell, and the anti-
sedimentation mechanism is fixedly connected to the interior of the sampling mechanism. By arranging the anti-
sedimentation mechanism, four reciprocating lead screws are driven by four second gears to rotate,
sediment of
drilling fluid in the four sampling barrels is prevented from sinking to the bottom during standing, four second sliding plates are driven by the four reciprocating lead screws to slide, and the situation that when the four sampling barrels rotate, the
sediment in the drilling fluid in the four sampling barrels is blocked is avoided.
Sediment in the drilling fluid in the sampling
barrel adheres to the wall under the action of
centrifugal force.
