Technical Field
The utility model belongs to the technical field of well completion sleeve pipe antiskid fastening, concretely relates to high reliability antiskid fastening well completion sleeve pipe.
Background
And (5) the final link of the well completion drilling project. In oil production, oil and gas well completion comprises oil layer drilling, well completion method selection, well cementation, perforation operation and the like. When a production zone with low permeability or a production zone seriously polluted by mud is subjected to production increasing measures such as acidizing treatment and hydraulic fracturing, well completion can be calculated, the main task of well completion is to ensure that a well hole is well communicated with a reservoir layer, the well can be high in yield, meanwhile, the long-term stability of the well hole is kept, and the well can be stable in yield for a long time.
SUMMERY OF THE UTILITY MODEL
To the problem that the above-mentioned background art provided, the utility model aims at: aims to provide a high-reliability anti-skid fastening completion casing.
In order to realize the technical purpose, the utility model discloses a technical scheme as follows:
the utility model provides a high reliability antiskid fastening well completion sleeve pipe, includes the sleeve pipe, both sides all are equipped with the screw thread about the sleeve pipe outer wall, both sides from top to bottom evenly paint the fixed glue between the screw thread, paint the fixed glue and be equipped with the quartz sand layer outward, the quartz sand layer outside evenly is provided with the solid fixed ring of a plurality of reinforcing bars, the solid fixed ring outside of reinforcing bar evenly is equipped with a plurality of reinforcing bars, the solid fixed ring of reinforcing bar is for taking the breach ring, the solid fixed ring's of reinforcing bar breach department is equipped with two corresponding locking pieces, the locking piece is equipped with the through-hole, the through-hole is connected with the bolt, the through.
Further defined, the quartz sand layer is composed of 20-30 meshes of quartz sand particles with uniform particles. The gaps among the quartz sand layer particles are increased through the structural design, and the existence and fixation of cement paste can be accommodated.
Further, the distance between two adjacent steel bar fixing rings is 2 m. The structural design makes the connection more stable.
Further defined, the thickness of the quartz sand layer is 1.5 mm. The area of contact of quartz sand layer and grout has been increaseed to such structural design.
Further defined, the diameter of the steel bar is 4 mm. After the cement paste is solidified, the steel bar has higher fixity due to the structural design.
The utility model has the advantages that: the contact area of reinforcing steel bars and cement is increased by using the reinforcing steel bars and the sleeves of different sizes in a matched mode through replacing reinforcing steel bar fixing rings of different specifications, gaps existing between particles of the quartz sand layer can enable the cement to exist and be fixed, the reinforcing steel bar fixing rings can fix the sleeves and the cement into a whole, stability is enhanced, and anti-slip performance is improved.

fig. 1 is a schematic cross-sectional structure diagram of a high-reliability antiskid fastening completion casing according to an embodiment of the present invention;
fig. 2 is a schematic top view of a high reliability anti-slip fastening completion casing according to an embodiment of the present invention;
the main element symbols are as follows:
the steel bar locking device comprises a sleeve 1, a quartz sand layer 2, a steel bar fixing ring 3, a steel bar 4, a locking block 5, a through hole 6, a bolt 7, a nut 8 and threads 9.
Detailed Description
In order to make the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below with reference to the accompanying drawings and examples.
As shown in fig. 1-2, the utility model discloses a high reliability antiskid fastening well completion sleeve pipe, both sides all are equipped with screw thread 9 about the 1 outer wall of sleeve pipe, evenly paint the fixed glue between the screw thread 9 of upper and lower both sides, paint the fixed glue and be equipped with quartz sand layer 2 outward, the 2 outside on quartz sand layer evenly is provided with the solid fixed ring of a plurality of reinforcing bars 3, the solid fixed ring of reinforcing bar 3 outside evenly is equipped with a plurality of reinforcing bars 4, solid fixed ring of reinforcing bar 3 is for taking the breach ring, the breach department of solid fixed ring of reinforcing bar 3 is equipped with two corresponding locking pieces 5, locking piece 5 is equipped with through-hole 6, through-hole 6 is connected with bolt 7, bolt 7 passes through-.
During manufacturing, the sleeve 1 is wholly preheated, special fixing glue is uniformly coated between threads 9 on the upper side and the lower side of the outer wall of the sleeve 1, 20-30-mesh quartz sand particles with uniform particles are uniformly coated outside the coated fixing glue, and a set of reinforcing steel bar fixing rings 3 are fastened at intervals of 2 meters from the end part of the sleeve 1. Through changing the solid fixed ring 3 of different specifications reinforcing bar, realize the use of not unidimensional sleeve pipe 1.
