In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings needed to be used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings based on these drawings without inventive labor.

Fig. 1 is a schematic view of the overall structure of the present invention.

Reference numerals: 1-central tube, 2-sleeve, 3-upper joint, 4-upper lantern ring, 5-elastic claw, 6-upper cone, 7-pressing cap, 8-slip sleeve, 9-slip sheet, 10-lower cone, 11-filling tube, 12-lower joint, 13-ball seat, 14-guide shoe.

Detailed Description

As shown in fig. 1, the extrusion circulation integration sand control instrument that this embodiment specifically discloses, including center tube 1, the upper end of center tube 1 is equipped with sleeve 2, sleeve 2 passes through top connection 3 with center tube 1 and is connected, the below of sleeve 2 is equipped with the lantern ring 4, go up lantern ring 4 and pass center tube 1, the upper end of going up lantern ring 4 is connected with the lower extreme of top connection 3, go up lantern ring 4's lower extreme fixed mounting elasticity jack catch 5, the below of elasticity jack catch 5 is equipped with cone 6, elasticity jack catch 5 is connected through cap 7 that pushes down with last cone 6, the lower extreme fixed mounting slip cover 8 of last cone 6, slip cover 8 fit in installs several evenly distributed's slip piece 9, cone 10 under the lower extreme fixed mounting of slip cover 8, the lower extreme fixed mounting packing section of thick bamboo 11 of packing section of thick bamboo 11, the inside below of center tube 1 sets up ball seat 13. The gravel-circulating extrusion and filling machine is reasonable in structural design and convenient to use, can effectively combine the functions of once extrusion and circulating filling of gravel, can greatly improve the working efficiency, saves the working time and reduces the construction operation procedures. When using this device, use cable, wire rope or oil pipe to descend the well to this device to suitable position, can be equipped with multiple bottom and connect, this device allows oil pipe flexible, can not unexpected deblocking this device when taking out oil pipe and seal assembly, because take the cover slips and deblocking mechanism to be located the protected area of seal element below, retrieves very easily. Packer deblocking mechanism does not receive the influence of pressure differential or tail pipe weight to putting into the spheroid through center tube 1, and the spheroid can fall on ball seat 13, puts into a spheroid from filling the center tube 2 and takes a seat on ball seat 13, and slips piece 18 is released and can block on oil well casing inner wall, opens through elasticity jack catch 5, and oil well casing annular space is sealed, through constantly punching press to center tube 1 is inside to can extrude, can fill the well inside through filling a section of thick bamboo 11.
