Description

Technical field

[0001] The present invention relates to the field of petroleum and sand, and in particular, there is a kind of oil-shaped gravel filtering device. Background technique

[0002] The gravel is often carried during the oil mining, and the gravel is worn on the oil pipeline. Therefore, it is necessary to install the gravel filter device for the tubing. However, the existing gravel filter device needs to stop the sand, which requires stopping sand, reducing the speed of oil, in order to Avoid stopping oil delivery for sand sand, the existing method is to set a redundant sandset device, when a sand sand device needs to be sanded, close it to use another sand-bearing device for sand, but this way makes it huge The cost is high, and the filtering device is not blocked.

[0003] How to set the prevention of filtering devices from clogging, while do not affect oil delivery, it is urgent to solve. Inventive content

[0004] The present invention provides a petroleum opening...
