Patented Mar. 26, 1946 AIPARATUS Willis P. Orr, Houston, Tex., assignor to Standard Oil Development Company, acorporation of Delaware Application October 5, 1942, Serial No. &60,734
` 7 Claims. (Ci. iee-20) The present invention is directed to apparatus adapted to aid in cleaning a well before producing through a screen.
In my co-pending application, Serial No. 4603733, filed October 5, 1942, now abandoned, a method of cleaning wells before producing through a screen is' disclosed. The method therein disclosed involves blocking off of the screen and removing foreign bodies from the well by fiowing well fluid through a by-pass at a relatively high velocity. After the cleaning step the bypass is closed and the well then produced through the screen. .As disclosed in the aforesaid application, a number of arrangements maybe employed to carry out the procedure. The present application is directed to an embodiment useful for practicing the method claimed in my above menticned application. i
Other objects and advantages of the present invention may be seen from the following description taken with the drawing in which Figures -1 and 2 are elevations partiy in section, Figure 1 showing the device adjusted to by-pass a screen and Figure 2 illustrating the device arr-anged for fluid flow through ,the screen.
The invention may be described briefly as including side ports arranged to by-pass a screen and a valve arranged at the upper end of the screen to close off the screen from the Joy-pass. The device is arranged so that after the well is cleaned manipulative steps performed by an operator at the surface will close the by-pass and open the valve to allow production through the screen into the tubing.
Turning now specifically to the drawing, the lower portion of a hole is disclosed with the lower end of casing I I provided with a conventional cement plug !2. Within the casing and secured to a lower end of a string of tubing l3 for loweri Ledge i& is provided with lefthand' screw threads 20 whichtmate with similar threads on coupling member 2l attached. to the lower end of tubing [3 and serve as a means of attaching the assembly to the string of tubing. Spaced above collar Zi is another coilar 22 carrying packe r setting tool 23, the two collars being separated by a short joint of tubing za. This joint of tubing is provided with a longitudinally extending slet 25. e
In Operating the device of the present invention, tubing !5 having attached thereto the'assembly arranged as illustrated in Figure 1 islowered into the bore hole until the liner is on bottom, or -alternatively the liner may be hung in position by slip's. The tubing may 'thenbe rotated to the right'to disengage left hand threads 20 and the tubing raised enough to engage packer setting, tool 23 with packer l'l. The weight of the tubing'is then allowed to rest on the packer An elongated body which is shown in in an amount sumcient to operate it to seal the annular space betweencylindrical member i! and casing ll; Thewell is then allowed to flow through side ports 26, 29 to remove foreign material from the annular space deflned by the screen and the bore hole and from the Iace of the producing formation. i
After the well is cleaned the by-pass may be closed and flow through the screen initiated by either of the manipulative steps:
(1) An overshot on a wire line may be dropped inside the tubing to engage spear head 31. An upward pull on the wire line will first pull plug .38 out of member 34. Additional upward movement will 'engage member 40 with pin 3! to raise sleeve 21 to its uppermost osition where it is located with side port 26 closed by member 21. An additional pull on the wire line will first shear pin 3|,- then pin 39 to release elongated body this operation is completed the tubing may be allowed to move downward to re-engage packer setting tool with packer l'l.
Having fully described and illustrated the pres- .ent invention, what I desire to claim is:
1. A device adapted to be arranged in a bore hole comprising in combination a cylindrical member having side ports in an upper portion thereof, an inwardly projecting circular ledge secured to a lower portion of said member, a sleeve provided with'ports corresponding to the ports of said cylindrical member slidingly ar-- ranged in said cylindrical member, a shoulder secured to said cylindrical member limiting the downward movement of said sleeve a second shoulder secured to said sleeve member limiting the upper movement of said sleeve, a plug arranged to cooperate with said inwardly projecting'ledge to seal the lower end of said sleeve when in a flrst position and to allow flow through the'opening defined by said ledge when in a second position, means adapted to be secured to a string of tubing for moving said sleeve from said 'first to said second position and said plug from said first to said second position.
2. A device in accordance with claim 1 in which the means for moving said sleeve includes a shear pin and said means for moving said plug includes a second shear pin.
3. A device in accordance with claim 1 including a rod attached to said plug, a spear head secured to said rod adapted to be engaged by a grappling tool, a member secured to the upper end of said rod by a shear pin and a shear pin attached to said sleeve for engagement with said member. I

5. A device adapted to be arranged in a borehole and to be attached to the upper end o! a liner 'screen comprising, in combination, a cylindrical member provided with side ports, a packer body mounted on said cylindrical member above said ports, a sleeve member carried by said cylindrical member and arranged to expose said side e ports when in a first position and to close said ports when in a second position relative to said cylindrical member, a valve member arranged to close the lower .end of said cylindrical member when in a first position and to allow fluid flow therethrough when in a second position relative means secured to said body arranged to engage said sleeve member and to move the sleeve and valve members 'from their first to their 'second positions as the body moves from its first to its second position.
6. A device in accordance with claim 5 in which a packer setting means is mounted on said tu r in 7. A device adapted to be arranged in a bore-. hole and tobe attached to the upper end of a liner screen comprising, in combination, a cylindrical member providedwith valve ports, a sleeve member carried by said cylindrical member and arranged to expose the ports when in a first position and to close them when in a second position relative to said cylindrical member, a valve member arranged to close the lower end of said cylindrical member when in a first position and to allow fluid flow therethrough when in a second position relative to said cylindrical member, a tubing member extending into the cylindrical member and provided with readily disengageable means securing it to said cylindrical member', an elongated body arranged in the lower end of said tubing to m`ove longitudinally therein from a first position to a second position and secured to said valve member to move it from its first to its second position as the elongated body is moved from its first to its second position, and means secured to said body arranged to engage with and move the sleeve member from its flrst to its second position as the body moves from its flrst to its second position.
