Skid-mounted oil well ten-closure one-separation recycling device

Abstract

The invention belongs to the technical field of fracturing flow-back fluid oil and sand separation devices in the initial production stage of dense oil wells, and particularly relates to a skid-mounted oil well ten-closure one-separation recycling device. The skid-mounted oil well ten-closure one-separation recycling device comprises a tank body of a cuboid structure, the interior of the tank bodyis divided into two bins in the width direction, the two bins comprise an anti-splashing buffering, settling and separating bin and a crude oil recycling bin, the two bins are isolated through an isolating plate, the portions, over the isolating plate, of the two bins communicate with each other, and the anti-splashing buffering, settling and separating bin is provided with a fluid inlet pipe inthe length direction; and a settling basin is arranged at the bottom of the anti-splashing buffering, settling and separating bin, a screw conveyer is installed in the settling basin, and the side face, corresponding to the output end of the screw conveyer, of the anti-splashing buffering, settling and separating bin is provided with a sewage draining port. According to the skid-mounted oil well ten-closure one-separation recycling device, silt in flow-back fluid can be settled, separated and discharged, the problem that a normal production system cannot treat the condition that the gas amountis small and the sand content is large in the fractured flow-back fluid in the early production period of the dense oil well is solved, and the good technical effect is achieved since application.

Description

technical field [0001] The invention belongs to the technical field of oil-sand separation devices at the initial stage of tight oil well production, and in particular relates to a skid-mounted ten-in-one separation and recovery device for oil wells. Background technique [0002] After large-scale fracturing of tight oil wells in oil fields, the oil content of the reverse drainage fluid is low, the sand content is large, and the amount of natural gas is low at the initial stage of production; The fluid contains a lot of sand and cannot be cleaned after it enters the normal production system. To sum up, the normal oil well production process cannot handle the reverse drainage fluid at the initial stage of fracturing. Contents of the invention [0003] In order to be able to deal with the reverse drainage liquid at the initial stage of mining, the present invention provides a skid-mounted oil well ten-in-one separation and recovery device. The present invention has the chara...
