Five, the specific embodiment:
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, solids ground catching device is designed to five valve square tubes remittance structural shape in the well, and it is made up of two straight tubes (4) and a straight pipe (6).Straight tube (4) is parallel with straight pipe (6) formation one or three pipes, and the pipeline that is interconnected is equiped with by-pass valve control in connection place, all is fixed with screen casing (5) in two straight tubes (4).Be provided with spacer pin (7) in the straight tube (4), spacer pin (7) contacts in screen casing (5) rear end, guarantees that screen casing (5) is in the center in straight tube (4), and strenuous vibration does not take place, and not by fluid impulsion displacement.
Be communicated with clip (2) at straight pipe (6) front end, described clip (2) is provided with No. three clip valves (13), all be communicated with cross (11) at described clip (2) front end and straight pipe (6) rear end, the cross (11) that is communicated with clip (2) is communicated with the oil well inlet line, and the cross (11) that is communicated with straight pipe (6) is communicated with the oil well outlet line.Two straight tubes (4) are positioned at straight pipe (6) both sides, all are communicated with threeway (3) at two straight tubes (4) front end, and the rear end is communicated with oil nozzle cover (8), is provided with oil nozzle (9) in the oil nozzle cover (8), are communicated with threeway (3) in oil nozzle (9) rear end.One port of the threeway (3) that is communicated with straight tube (4) front end is connected with plug (1), port and another clip (2) are communicated with in addition, described clip (2) is communicated with the cross (11) that is communicated with at straight pipe (6) front end, is respectively arranged with a clip valve (15) and No. two clip valves (14) on the clip (2).Threeway (3) one ports that are communicated with oil nozzle (9) are connected with plug (1), port and other clip (2) are communicated with in addition, described clip (2) is communicated with the cross (11) that is communicated with in straight pipe (6) rear end, is respectively arranged with No. four clip valves (10) and No. five clip valves (12) on the clip (2).
As shown in Figure 1, 2, screen casing (5) is the pipe that two ends are not sealed, and spreads all over sieve aperture (17) on its tube wall, is with ring baffle (16) in screen casing (5) front portion, and the rear portion is with wiper block (18).Wiper block (18) is a disk, is 120 degree on its circumference and is distributed with the leg that extend in three straight footpaths.Ring baffle (16) contacts with straight tube (4) inner wall sealing, prevents that solids enters into the annular space between straight tube (4) and screen casing (5) and do not have the seizure effect in the well.Wiper block (18) is guaranteed to keep certain space between screen casing (5) and straight tube (4), and both are directly contact not.
Restriction choke on the well head production tree is the charge of oil mouth not, is connected to the entrance point of solids ground catching device in the well with pipeline, is connected to eliminator and measuring tank behind the catching device of solids ground in the well.Open plug (1), tighten plug (1) after being installed to screen casing (5) in the straight tube (4).Open one, No. four clip valve (15), (10), close two, three, No. five clip valves (14), (13), (12), open the well head production tree and produce valve, the fluid that has solids in the well flows out by a clip valve (15), screen casing (5), oil nozzle (9), No. four clip valves (10) in turn, solids can't pass through screen casing (5) in the well, is trapped in the screen casing (5).Pressure by the solids ground catching device entrance point and the port of export in the observation well changes, judge whether screen casing (5) is filled up or stop up by solids in the well, if be filled or stop up, open two, No. five clip valves (14), (12) of opposite side, close one, No. four clip valve (15), (10), enter into the production of another root straight tube (4).Open the plug (1) of blocked straight tube (4), take out screen casing (5), after solids in the well in it is taken out, stand-by after reinstalling.After solids in the well is got rid of totally, on the restriction choke on the well head production tree, oil nozzle is installed, close one, two, four, No. five clip valve (15), (14), (10), (12), open No. three clip valves (13), borehole fluid is produced by straight pipe (6).
