Abstract
The present invention discloses a device for catching falling objects in a well in petroleum industry, which is suitable for matching a well using an electric submersible pump for oil extraction with an electric submersible pump. The device can also be used for production pipe columns in other oil wells, matched with well repairing operation and used for catching and deterring falling objects in a well. The device comprises a shaft rod and a basket, wherein the basket is arranged on the lower part of the shaft rod. The device is connected with the lower part of an electric pump machine set or the bottom of a descent pipe column, and descends into a well together. When the electric submersible pump pipe column of other descent pipe columns are lifted, the end of the basket body uses a large caliber for catching or deterring fallen small objects including cable clamps or protecting covers, etc. Therefore, the present invention achieves the purposes of cleaning a well bottom, eliminating hazards and reducing production cost.
Description
Technical field
The present invention relates to the down-hole oil production equipment of petroleum industry, particularly trouble of lost tool in hole catcher, be suitable for well, with the supporting use of electric submersible pump with electric submersible pumping.The oil well that also can be used for other is in order to catch and to canvass trouble of lost tool in hole.
Technical background
In the electric submersible pumping technology of petroleum industry, during the electric submersible pumping well operations, be subjected to the influence of situations such as instrument quality, operation reason, run into the well problem that comes off of strain relief clamp, guard shield through regular meeting.Because strain relief clamp adopts the manufacturing of high hardness alloy material, and out-of-shape, fall to salvage behind the well and handle very difficulty, give the fishing for of downhole tool equipment such as removing, downhole packer of shaft bottom sand setting, bore construction such as mill cement plug and bring serious future trouble.Electric submersible pumping well strain relief clamp, guard shield are fallen the problem of well, also untappedly at present go out effective know-how and solve this type of problem.The thinking settling mode of inertia also rests on the fishing tool of how development and design strain relief clamp and guard shield, not from how preventing the junk down-hole hand research that falls.For other producing well, how the problem that equally yet exists trouble of lost tool in hole to salvage does not prevent object the fall instrument and the measure of well yet.
Summary of the invention
The objective of the invention is development and design trouble of lost tool in hole catcher, fill up the blank that does not have trouble of lost tool in hole reception, trap tool at present.Make it have the ability of catching or canvassing smallclothes junks such as strain relief clamp, guard shield.Changing the mode of thinking, starting with, this equipment is gone into the well with electric submersible pump tubing string or other flow string, catch the smallclothes junks such as strain relief clamp guard shield that fall well because of a variety of causes, eliminate future trouble, thereby reduce production costs from how solving the small article well problem that falls.
Use the present technique solution can reach above-mentioned purpose: the trouble of lost tool in hole catcher comprises axostylus axostyle and basketry, and basketry is made up of basketry body and basketry seat, for being connected and fixed or integral manufacturing, basketry is installed on the bottom of axostylus axostyle between basketry body and the basketry seat.The basketry body is a tubular body, and the upper end opening diameter is greater than the basket diameter, and upper end open is processed with a plurality of vertical slots, vertical slot bottom basket distribution hole or slit.Connect in the bottom of electric pump unit or the bottom of running string, together G.I.H.
The present invention compared with prior art, the starting point difference of dealing with problems has significant effect.Its main feature is: 1, basketry adopts the upper port radial elastic to regulate and the design of wide abdominal cavity basketry body, and its external diameter is abutted on the internal surface of sleeve pipe, can reach best seizure effect.2, be processed with hole or slit at the bottom of the basketry body basketry, flow to guarantee well liquid non-resistance.3, last lower contact connects design with axostylus axostyle anti-back-off pin, the basketry difficult drop-off, and resistance to overturning is good.4, this tool construction is simple, with low cost, has eliminated the fall future trouble of well of small article, greatly reduces cost of production.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed description: referring to accompanying drawing, the present invention is made up of axostylus axostyle 3 and basketry, is installed on the bottom of axostylus axostyle 3.Basketry is made up of basketry body 4 and basketry seat 5, and basketry body 4 is connected and fixed with basketry seat 5.Basketry body 4 is tubular bodies, and the upper end opening diameter is greater than the diameter of basket, and upper end open is processed with a plurality of vertical slots, makes its diameter have the flexible adjustment effect, can abut on the internal surface of sleeve pipe, reaches the best effect of catching.The basket distribution hole or the slit of vertical slot bottom make the well liquid non-resistance that flows, and its underpart and basketry seat 5 are connected and fixed.Basketry seat 5 is provided with endoporus, and endoporus cooperates with axostylus axostyle 3 bottoms, is set on the axostylus axostyle 3 or is welded on the axostylus axostyle 3; Basketry seat 5 housings are evenly distributed with the hole of many up/down perforations, make things convenient for flowing of well liquid, and top and basketry body 4 are connected and fixed.Axostylus axostyle 3 two ends external diameters are processed with screw thread and groove, and in the top of basketry seat 5, the external diameter of axostylus axostyle 3 is provided with boss, carry out spacing to basketry seat 5.When the internal bore welding of basketry seat 5 is connected on the axostylus axostyle 3,, can keep or cancel the boss of axostylus axostyle 3 external diameters because boss is inoperative.As required with the installation site of the present invention on flow string, axostylus axostyle 3 can be designed to hollow stem or solid hopkinson bar, two ends are connected with lower contact 6 with top connection 1 respectively, the position of top connection 1 and lower contact 6 corresponding axostylus axostyle 3 grooves, be respectively equipped with screw hole, interior cartridge screw 2.Top connection 1 can also with axostylus axostyle 3 integral manufacturings; Lower contact 6 can also be designed to nut shape or adopt welding manner to fix, and also can select other connecting mode for use or be designed to difformity according to user's needs.When the internal bore welding of basketry seat 5 is connected on the axostylus axostyle 3, when the bottom does not connect miscellaneous equipment or tubing string again, because not effect of lower contact 6 can be cancelled lower contact 6.Basketry can also integral manufacturing, during integral manufacturing, basketry upper end opening diameter is greater than the basketry lower diameter, upper end open is processed with a plurality of vertical slots, liquid flow hole distributes on the basketry, be directly welded in basketry bottom installing hole on the axostylus axostyle 3 or be set on the axostylus axostyle 3, the bottom connects lower contact 6 or the like.
The present invention is connected to the bottom of motor or the G.I.H bottom of electric pump pipe column when using as the electric submersible pump auxiliary equipment, in well, whole tubing strings and electric submersible pump unit are proposed during the inspection electric pump, also the present invention and other auxiliary equipment are carried to ground simultaneously, can remove the seizure thing in the basketry of the present invention, reach the purpose at the bottom of the clear well.The present invention also is applicable to the different mining tubing string in other producing well, or cooperates workover treatment, prevents the little junk well that falls, and when being used for other oil recovery producing well or running string, the present invention is connected in the bottom of flow string.
