Abstract
The utility model discloses a floating section hoop. The floating section hoop comprises a body; the floating section hoop is characterized in that the body is cylindrical; internal threads are processed inside the left side of the body; external threads are processed outside the right side; the screw thread direction, shape and pitch of the external threads are same as those of the internal threads; the external threads can be matched with the internal threads; a blind plate is arranged in the middle of the body; the blind plate and the inner wall of the body are sealed through a blind plate rubber ring; the blind plate is fixed through a snap ring. The floating section hoop is guarantee for lowering a casing pipe smoothly during well completion, and is simple in processing technique, convenient to mount and use, and good in construction adjustability; the two ends of the section hoop are ensured to be isolated by the blind plate and the rubber ring; poured slurry is prevented from leaking to the lower part; after casing pipe lowering is fulfilled, certain pressure is applied, and the blind plate is crushed; during operation period of well completion, well completion quality is improved; the floating section hoop has remarkable advantages on manufacturing technique, assembly and disassembly.
Description
Technical field
The utility model relates to oil well completion field, specifically a kind of floating completion system.
Background technology
Along with the increase of the large horizontal well quantity in China some areas, the innovation of the completion mode to advantages of simple is extremely urgent, and original completion tool can not be best complete completion, cause constructional difficulties, completion is of poor quality etc., can not meet the demand of engineering, this just requires us to need more advanced technology and equipment to solve this difficult problem.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of semi-rigid centralizer, and it is smooth that this device effectively ensures that sleeve pipe is transferred.Prevent that underground equipment from damaging, and ensures normally carrying out of construction.
The purpose of this utility model is carried out specific implementation by the following technical programs:
A kind of floating joint hoop, comprise body, body is tubular, the inside, left side of body is processed with internal thread, and the external process on right side has external screw thread, and externally threaded thread rotary orientation and screw thread form, pitch are identical with described internal thread, make described external screw thread can with described screw-internal thread fit, middle part at body is provided with blind plate, pass through blind plate rubber sealing, and described blind plate is fixed between described blind plate and the inwall of body by snap ring.
Described blind plate is made up of special glass, is preferably tempered glass.
On body and blind plate, all scribble paint.
Blind plate cushion rubber has good sealing, can two ends are completely isolated.
There is the screw thread button-type coordinating completely at two ends, left and right, ensure that floating joint hoop is installed on sleeve pipe smoothly.
A kind of floating joint hoop of the utility model, the guarantee that while being completion, sleeve pipe is transferred smoothly, processing technology is simple, easy to install, and construction controllability is good.Blind plate and cushion rubber ensure that joint hoop two ends are isolated, ensure that the mud of perfusion can not drain to bottom.After having sent under sleeve pipe, apply certain pressure, blind plate is crashed to pieces.Thereby improve completion quality the duty cycle of completion, and there is clear superiority in manufacturing process and mounting or dismounting.
Brief description of the drawings
According to drawings and embodiments the utility model is described in further detail below.
