Abstract
The oil well sampling device is applied to oil extraction well mouth measurement sampling in the oil field. Is characterized in that: mainly constitute by body, blade, sampling tube and sample valve, the welding has a sampling tube on the body wall, and threaded fixation has a sample valve on the sampling tube. The method is characterized in that: two blades are welded in the pipe body, the edges of the two blades are welded with the inner wall of the pipe body, the two blades are identical in shape, and the included angle between the two blades and the horizontal plane is 45-60 degrees; the sampling tube is located blade downstream position and the distance of two blades apart from the sampling tube is 1 ~ 1.5 times of the diameter of body. The effect is as follows: the accuracy and the representativeness of crude oil sampling containing free water produced by an oil well are improved, the problem of inaccurate recording of crude oil water-containing data is solved, and the device also has the advantages of simple structure, convenience in operation, low cost and easiness in popularization.
Description
Technical field
The utility model relates to oil field oil recovery field of measuring techniques, and particularly a kind of oil well sampling that contains free water crude oil is a kind of oil well sampler.
Background technology
In the oilfield oil recovery gage work, the oil well sampling is an important link, the order of accuarcy of the oil sample accuracy of acquisition and representative direct relation petroleum metering data, and the oil sample data are also most important to the oil field geologic analysis accurately simultaneously.At present, the widely used sampler in oil field is straight length or short circuit of standpipe section welding of pipeline behind the production tree oil nozzle, fixing valve on pipe nipple.Aperture through by-pass valve control draws oil sample.Because the well flow is moving to be non-homogeneity, the data difference of obtaining sample is bigger, particularly when oil well contains free water; Because the viscosity of water is less, better mobile, viscosity of crude is bigger; Mobile relatively poor, can cause the gentle middle flow at high speed of water at pipeline section, crude oil flows along tube wall; Relative velocity is slower, and therefore, the oil sample error that obtains according to traditional sampler is bigger.
The utility model content
The purpose of the utility model is: a kind of oil well sampler is provided, the pipeline profit is mixed, the sample of obtaining is accurate.
The technical scheme that the utility model adopts is: the oil well sampler, mainly form by body, blade, probe tube and sample cock, and on tube body wall, be welded with a probe tube, screw thread is fixed with a sample cock on the probe tube.It is characterized in that: in body, be welded with two blades, the inwall of two blade edges and body welds together, two blades be shaped as helical form, two blades and horizontal plane angle are between 45～60 °; Probe tube is positioned at 1～1.5 times of diameter that blade downstream position and two blade pitch are body from the distance of probe tube.
After the inhomogeneous fluid of oil well output ran into blade, fluidised form was changed into from streamlined flow and is rotatablely moved, and oil, water will evenly mix, thereby reach the purpose of getting accurate oil sample.
The beneficial effect of the utility model: the utility model oil well sampler; The accuracy and representativeness of the crude oil sampling that contains free water of oil well output have been improved; Solved the inaccurate problem of crude oil water containing data admission, also have simple in structure, easy to operate, cost is low, be easy to promote.
