Embodiment 1

[0031] Closed high-sulfur crude oil liquid desanding device, such as figure 1 and figure 2 As shown, it includes an airtight casing 1, which is arranged in the airtight casing 1 and divides the airtight casing 1 into two or more chambers from left to right. The oil feed above the first chamber on the left is set Port 3, the oil outlet 4 that is arranged under the first chamber on the right, the sand body reservation chamber 5 that is arranged on the left side of each partition 2 and is located at the bottom of the chamber, and is installed at the bottom of the sand body reservation chamber 5 The sand-connecting filter 6 at the end; the sand-connecting filter 6 includes a sealed box body 61, and a filter screen 62 arranged in the sealed box body 61 is arranged at the top of the sealed box body 61 and communicates with the bottom end of the sand body reserved cavity 5 An inlet 63 and an outlet 64 arranged at the bottom of the sealed box body 61 ; the inlet 63 is provided with ...

Embodiment 2

[0036] The present embodiment optimizes the structure of sand filter 6 on the basis of embodiment 1, as figure 2 and image 3 As shown, the specific settings are as follows:

[0037] The sealed box body 61 is composed of a box body 611 , a box cover 612 arranged at the top of the box body 611 , and a sealing ring 613 installed between the box body 611 and the box cover 612 for sealing.

[0038] The filter screen 62 in the sand receiving filter 6 is arranged in parallel in the sealed box body 61 , and the filter screen 62 divides the sealed box body 61 into more than two filter chambers.

[0039] In this embodiment, the sand that enters the sand receiving filter 6 is filtered and the sand is accumulated in the sand receiving filter 6, and the filtered liquid is returned to the airtight housing 1 through the oil feed port 3 . When the sand body in the sand-connecting filter 6 is accumulated to a certain degree, the whole sand-connecting filter 6 can be replaced, thereby effe...

Embodiment 3

[0041] The present embodiment has optimized the setting of separating net 2 on the basis of embodiment 2, and concrete structure is as follows:

[0042] The top of the spacer 2 is inclined 10-40 degrees toward the oil feed port 3 . In this embodiment, the inclination of the spacer 2 is 30 degrees.

Abstract

The invention discloses a sealing type high-sulfur-bearing oil stoste sand removing device. The problem that in the prior art, equipment suitable for high-sulfur-bearing oil screening does not exist is mainly solved. The device comprises a sealing shell body, partitioning nets which are arranged in the sealing shell body and divides the sealing shell body into at least two cavities from left to right, an oil feeding opening formed above a first cavity on the left, an oil discharging opening formed below a first cavity on the right, sand body reserved cavities which are arranged on the left sides of the partitioning nets and are placed at the bottom ends of the cavities and sand receiving filters arranged at the bottom ends of the sand body reserved cavities. The sand receiving filters comprise sealing box bodies, filtering screens arranged in the sealing box bodies, inlets formed in the top ends of the sealing box bodies and the bottom ends of the sand reserved cavities and outlets formed in the bottom ends of the sealing box bodies. The inlets are provided with first valves. The outlets are provided with second valves. The device has the advantages that oil sand content is lowered, the body health of operation personnel is guaranteed, and cost is low.

Description

technical field [0001] The invention relates to a petroleum desanding device, in particular to a closed-type high sulfur-containing petroleum stock solution desanding device. Background technique [0002] The main function of the oil screen is to prevent sand. Due to the geology of the oil well and the different sand layers, the steel grades and types of the pipes used are different. [0003] In oil drilling and production operations, screen pipe is an important equipment, and it is often used for pre-completion or oil production for sand control. At present, the most widely used screen is the wire-wrapped screen. The manufacturing method of this kind of screen pipe is: winding a steel wire of a certain cross-section on the metal liner pipe evenly distributed on the surrounding screen rods or openings and welding it firmly, and leaving a certain gap as a screen hole. Although this manufacturing method has been used by many manufacturers in China, there are some problems wh...
