Embodiment 1

[0020] Embodiment one: as attached figure 1 As shown, the hydraulic unblocking tool for the filter screen of the desander includes a hydraulic manual pump 1, a hollow hydraulic jack 2, a gland 3, a screw 4, connectors, a pressure plate 5 and bolts 9, and the gland The middle part of 3 is provided with a mounting hole through up and down, the upper end of the screw 4 passes through the mounting hole, the lower end of the screw 4 is fixedly connected with a connecting piece for connecting the filter screen 11, and the hollow hydraulic jack 2 is seated on the top surface of the gland 3, corresponding to the gland The lead screw 4 at the upper position of 3 passes through the through hole on the plunger 8 of the hollow hydraulic jack 2, and the outer side of the lead screw 4 at the position above the plunger 8 is detachably and fixedly installed with a pressure bearing plate 5. The bottom surface is against the top surface of the plunger 8 , the outer diameter of the pressure plat...

Embodiment 2

[0026] Embodiment 2: A method of using the above-mentioned hydraulic deblocking tool for the filter screen of the filter type desander, comprising the following steps:

[0027] In the first step, the pressure bearing plate 5, the hollow hydraulic jack 2, and the gland 3 are removed from the lead screw 4.

[0028] In the second step, the connector at the lower end of the screw 4 is connected to the suspension ring 13 on the filter screen 11, then the gland 3 is placed outside the screw 4 and the gland 3 is installed on the upper surface of the filter cartridge 10, and then the The hollow hydraulic jack 2 is set on the outside of the lead screw 4 and seated on the top surface of the gland 3, so that the lead screw 4 is located inside the through hole of the plunger 8 of the hollow hydraulic jack 2, and the pressure plate 5 is screwed on the lead screw 4, The bottom surface of the pressure bearing plate 5 is offset against the top surface of the plunger 8 of the hollow hydraulic ...

Abstract

The invention relates to the technical field of filtering type desanders, in particular to a hydraulic jam release tool for a filtering type desander filter net and a using method thereof. The hydraulic jam release tool comprises a hydraulic manual pump, a hollow hydraulic jack, a gland, a lead screw, a connection piece, a bearing plate and bolts; the middle of the gland is provided with an installation hole which is through in the vertical direction; the upper end of the lead screw penetrates through the installation hole, and the lower end of the lead screw is fixedly connected with the connection piece; the hollow hydraulic jack is located on the top surface of the gland; the lead screw penetrates into a through hole formed in a plunger; the bearing plate is detachably and fixedly installed on the outer side of the lead screw, and the bottom surface of the bearing plate abuts against the top surface of the plunger of the hollow hydraulic jack; and a hydraulic robber pipe is connected with the hydraulic manual pump and the hollow hydraulic jack. The hydraulic jam release tool is reasonable and compact in structure and convenient to use, the filter net is lifted out from a filterbarrel through the hollow hydraulic jack, the situation that a filter net is pulled by force from a filter net by a manual hoist crane or the filter net cannot be taken out even a lifting ring is broken is avoided, accordingly, the manpower and material resources are saved, and the taking-out operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of filter desanders, in particular to a hydraulic jam release tool for filter screens of filter desanders and a method for using the same. Background technique [0002] The filter desander is used in the process of oil field trial production, mainly to filter the fluid in the well and protect the ground equipment. The fluid is introduced into the cylindrical filter cartridge through the inlet of the desander, and the filter cartridge is equipped with a filter net. The filter screen filters and collects the solid phase impurities in the fluid in the filter screen, and the clean fluid is led out of the filter screen to the outlet of the desander to complete the fluid filtration process. When cleaning, the filter screen is taken out from the filter cartridge by a manual hoist. However, during on-site use, it often occurs that the filter screen is stuck in the filter cartridge due to deformation of the filter ...
