Description
Technical field
The present invention relates to horizontal well completion tubular pile enters instrument under auxiliary, a kind of firm resistance absorber of the fall applied in horizontal well completion tubular pile.
Background technology
Owing to horizontal well technology is in the large-scale promotion in oil field, the problem that some initial stages do not account for is the most following, such as Short Radius Horizontal Wells, the problem entering difficulty under completion tubular column is all there is in the hole conditions such as long horizontal sections horizontal well or the bigger horizontal well of the degree of depth in Completion Operations, in the well track irregular well example particularly caused because of misoperation in some complex geologic conditions and drilling process, enter under completion tubular column and be easily hampered.Cause under tubing string not in place.This kind of situation once occurs, may result in the instrument dislocation on tubing string, casing cementing mode is not bad in this way, simply a loss point oil layer section, but if special well, picture needs pressure break completion or screen casing crest water flooding bricklayer's's skill completion all can cause packer card seal point to misplace, light then cause Party A to lose several sections of exploitation oil reservoirs, heavy then cause whole process failure, it is impossible to carry out lower step construction, the most whole oil well is scrapped, and loses the most serious.And existing completion technique does not still have effectively to reduce the instrument of tubing string local stiffness, the particularly local stiffness between large scale work, therefore develop and a kind of can then reduce tubing string specific purpose tool of excessive dog-leg severity in well track be just particularly important by reducing tubing string local stiffness.
Summary of the invention
It is an object of the invention to provide a kind of firm resistance absorber of the fall applied in horizontal well completion tubular pile, solve horizontal well completion tubular pile because of in wellbore trajectory dog-leg severity excessive and enter the problem of difficulty under causing, reduce tubing string entirety frictional resistance by reducing tubing string local stiffness.
In order to reach above-mentioned purpose, present invention employs following technical scheme, a kind of firm resistance absorber of the fall applied in horizontal well completion tubular pile, including work urceolus, special material cylinder, work inner core, described special material cylinder is connected to work inner core upper end, be loaded work outer barrel by the bottom of work urceolus the most together；The lower end of described work urceolus is provided with spacing bottom hung ring with work inner core upper end position.
The standard of the described special material cylinder linked together and work inner core loading work outer barrel is at least completely special material wound packages to be entered work outer barrel；Described special material cylinder is metal that bending stiffness is less or nonmetallic materials are made.
Described work inner core upper end outer wall processes the sphere that two convex-concaves are connected respectively, two spheres respectively with the sphere Corresponding matching that arranges on work urceolus and bottom hung ring.
Described work inner core internal diameter is identical with special material cylinder internal diameter, and upper end is machined with the screw thread matched with special material cylinder lower end screw thread；Work inner core bottom outer wall is machined with casing threads.
The inwall upper end of described work urceolus is machined with casing threads and the limited step of special material cylinder, and lower end inner wall is machined with the connection screw thread mated with bottom hung ring and its top is machined with the concave ball surfaces mated with the inner core spirogyrate sphere that works.
Described special material cylinder is the tubular that upper coarse and lower fine inwall is isometrical, and external wall of upper portion is machined with at least 1 seal groove, and lower end is machined with the coupling screw thread being connected with the inner core upper end that works.
Described bottom hung ring inwall upper end is machined with the convex spherical inside surface matched with the inner core top exterior walls concave outer surface that works, and inwall is processed as the upper coarse and lower fine conical surface of certain angle, and below inwall, it being machined with seal groove, outer wall upper end is machined with the connection screw thread matched with the urceolus that works.
Compared to prior art, the method have the advantages that
Solve the conventional completion tubular column problem that local stiffness that is that cause is excessive because the connection of large scale instrument is overstocked, improve the safety of Well Completion Engineering of Oil Reservoirs to greatest extent, and this tool construction is simple, reliable operation, perfect in shape and function, the suitability is wide, low cost, requires low to the condition of use.On-the-spot application is convenient, requires relatively low to the technology of construction team, and operational procedure is identical with conventional completed well process, this instrument can be placed any desired position of horizontal well completion tubular pile, it is not necessary to any additional step.Therefore, there is significant economic benefit and bigger popularization and application space.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation dropping firm resistance absorber applied in horizontal well completion tubular pile of the present invention.
In figure: work urceolus 1, special material cylinder 2, work inner core 3, bottom hung ring 4.
Detailed description of the invention
Detailed description for the present invention and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides reference and purposes of discussion, is not used for being any limitation as the present invention.
With reference to shown in Fig. 1, a kind of firm resistance absorber of the fall applied in horizontal well completion tubular pile, special material cylinder 2 and work inner core 3 are by after screwed connection, loaded by the bottom of work urceolus 1, bottom hung ring 4 is inserted in and passes through bottom screw thread and work urceolus 1 from work inner core 3 bottom to connect, by spacing for work inner core 3.Wherein special material cylinder 2 is metal that bending stiffness is less or nonmetallic materials constitute (such as wearability engineering plastics etc.), work inner core 3 outer wall top process respectively two convex-concaves be connected and respectively with work urceolus 1 and the sphere of bottom hung ring 4 Corresponding matching.
Work inner core internal diameter is identical with special material cylinder internal diameter, and upper end is machined with the screw thread matched with special material cylinder lower end screw thread；Work inner core bottom outer wall is machined with casing threads.The inwall upper end of described work urceolus is machined with casing threads and the limited step of special material cylinder, and lower end inner wall is machined with the connection screw thread mated with bottom hung ring and its top is machined with the concave ball surfaces mated with the inner core spirogyrate sphere that works.Described special material cylinder is the tubular that upper coarse and lower fine inwall is isometrical, and external wall of upper portion is machined with at least two seal groove, and lower end is machined with the coupling screw thread being connected with the inner core upper end that works.Described bottom hung ring inwall upper end is machined with the convex spherical inside surface matched with the inner core top exterior walls concave outer surface that works, and inwall is processed as the upper coarse and lower fine conical surface of certain angle, and below inwall, it being machined with seal groove, outer wall upper end is machined with the connection screw thread matched with the urceolus that works.
