Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model sand control screen intensity detecting device.
Detailed description of the invention
The embodiment of this utility model sand control screen intensity detecting device: as it is shown in figure 1, sand control screen intensity detecting device, the device body 4 extended in left-right direction including axis, device body 4 in a tubular form and has the installation cavity loaded in left-right direction for sand control screen.The two ends, left and right of device body 4 are the most threaded left plug 2, a right plug 8, left plug 2, right plug 8 structure identical, be outer pipe plug, it is possible to achieve the exchange that left and right sides is installed.Hammering union joint 1 it is equipped with on left plug 2 and right plug 8.
Left plug 2 is provided with for installing the pipe nipple 3 connecting sand control screen, and pipe nipple 3 is positioned at installation cavity.Pipe nipple 3 is provided with fluid passage 31 the most through, that pass through for the liquid detected, fluid passage 31 connects the inside of sand control screen 5 in use, having annular space between the installation cavity of sand control screen 5 and device body 4, fluid passage 31 is connected with this annular space by the screened port on sand control screen 5.The most through left passage being communicated with fluid passage on left plug 2, the most through right passage being communicated with installation cavity on right plug 8.Hammering union joint 1, device body 4, left plug 2, pipe nipple 3 and right plug 8 are coaxial line assemblings, the feed pathway 11 of the hammering union joint 1 of left and right sides shape cost apparatus respectively and liquid outlet channel.The part of the left and right sides of pipe nipple 3 is all external screw thread, and the external diameter of left part is less than the external diameter of right part.For detecting undersized screen casing, on the left of pipe nipple 3, external diameter is likely equal to or more than right side external diameter.By arranging pipe nipple 3, according to the sand control screen (particularly radial size) of different size specification, pipe nipple 3 can be replaced, it is achieved various sizes of sand control screen maximum is resisted the intrinsic pressure and mensuration of critical external compressive resistance data.
The pressure-detecting device for detecting its internal pressure on device body 4, pressure-detecting device includes pressure transducer and fixing structure of sensor 9, and fixing structure of sensor 9 is plugged on device body outer wall.Fixing structure of sensor 9 has the inner chamber for installing sensor.Pressure-detecting device also includes flow transducer, and flow transducer is positioned at the outside of detection device, is connected with this detection device by pipeline.
For ensureing the stability of sand control screen, it is provided with in installation cavity for the centralizer 7 to sand control screen 5 righting diametrically, the sand control screen 5 of test is carried out righting placed in the middle.Centralizer 7 has the joint face that the supporting surface coordinated in use is connected with the periphery of sand control screen 5 with the support of device body 4 inwall.Centralizer 7 is set on sand control screen 5.Centralizer 7 uses the most totally enclosed annular so that the liquid mediums such as mud can along centralizer 7 axially through.
When concrete test uses, first sand control screen 5 to be tested is arranged on pipe nipple 3, from feed pathway 11 pumping liquid plugging material, plugging material forms a circulation by flowing out from liquid outlet channel after screen openings, in cyclic process, sand control screen eyelet is progressively blocked by liquid plugging material, cyclic process is controlled by pressure transducer and flow transducer video data, when sand control screen complete blocked after boost in pressure cause sand control screen to rupture to a certain numerical value, thus the maximum recording sand control screen resists intrinsic pressure data.When liquid plugging material pumps into from right plug, the maximum critical external compressive resistance data of sand control screen can be recorded.
In other embodiments, device body be not the good of circular tube shaped, such as profile be square, or triangular prism shaped, as long as its internal installation cavity disclosure satisfy that the installation of the sand control screen of different size.In other embodiments, pressure-detecting device may also set up Pressure gauge, for detecting the internal pressure data of device body.
In other embodiments, feed pathway may also be arranged on the sidewall of device body, highly pressurised liquid by device body radially into the installation cavity of its inside.In other embodiments, left and right plug also can not use threaded removable mounting means, it is possible to uses bolt to add the connected mode of sealing gasket, it is achieved the removable of left and right plug is tightly connected.In other embodiments, when the left plug installing pipe nipple is releasable connection, right plug also can fixing with device body be connected.
