Anti-blocking gravel filtering device for petroleum exploitation

Abstract

The invention relates to the technical field of petroleum sand removal, and discloses an anti-blocking gravel filtering device for petroleum exploitation, which comprises: a box body, wherein the left side of the box body is communicated with a petroleum inlet pipeline, the right side of the box body is communicated with a petroleum outlet pipeline, and the vertical filter screen plate is arranged in the box body and divides the box body into a left part and a right part; a cleaning device which is used for regularly cleaning gravels on the vertical filter screen plate; a gravel storage box which is fixedly arranged below the box body and communicates with the bottom, located on the left side of the vertical filter screen plate, of the box body, wherein a door plate is arranged at the bottom in a sealed mode, and the gravel storage box is used for cleaning gravel in the gravel storage box; a baffle device, wherein when the gravel is collected, the gravel storage box is communicated with the box body through the baffle device, and after the gravel is collected, the gravel storage box is sealed and isolated from the box body; and a petroleum return device which is arranged between the lower part of the gravel storage box and the petroleum outlet pipeline. The gravel filtering device can prevent blockage, does not influence petroleum transportation, is convenient to operate, and saves time and labor.

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...

Problems solved by technology

[0002] Sand and gravel are often carried in the process of oil extraction, which will cause wear to the oil pipeline. Therefore, it is necessary to install a gravel filter device on the oil pipeline. Avoid stopping oil transportation for sand removal. The existing method is to set up redundant sand removal devices. When one sand removal device needs sand removal, it is closed and another sand removal device is used for sand removal. However, this method makes the equipment bulky , the cost is higher, and it cannot prevent the filter device from clogging
