Abstract
A well cementation cement head fast connecting clamp hoop comprises a sealing connector, a clamp hoop body, an annular sealing element, a clamp ring assembly and a lock pin. The sealing connector is connected with the clamp hoop body in threaded mode. The annular sealing element is arranged in an inner cavity disposed on the lower portion of the sealing connector. A casing coupling arranged on the top of a casing tubular column is sleeved in the clamp hoop body. Sealing is formed between the upper end face of the casing coupling and the annular sealing element. The clamp ring assembly is arranged on the lower end portion on the periphery of the clamp hoop body. The upper portion of the clamp ring assembly is clamped on the clamp hoop body. The lower portion of the clamp ring assembly is clamped on an annular end face on the lower end of the casing coupling. The clamp ring assembly is locked through the lock pin. A main body of the well cementation cement head fast connecting clamp hoop is made of high-strength structural alloy steel, so the well cementation cement head fast connecting clamp hoop is high pressure resistant and long in service life. When the clamp hoop is arranged in the coupling, the clamp hoop is rotated certain angles and can complete connecting with a pipe string. Operation is simple and reliable, and well cementation efficiency is greatly improved. Casings which are applied just have the same size, and any kind of thread forms can be connected.
Description
Technical field
The utility model relates to the cementing cement head Quick joint hoop that uses in a kind of oil drilling technique, solves cementing cement head and well cementing pipe series winding and connects difficulty, is not easy to the problem that is threaded with particular tube.
Background technology
At present, known cementing cement head need to be connected with the pipe string by casing joint, the sleeve pipe of dissimilar connecting thread needs different casing joints, especially along with the now employing of more and more special threads, greatly limit the applicability of cementing cement head, so just needed a kind of joint that can make cementing head be applicable to various threaded sleeves.
Summary of the invention
The purpose of this utility model provides a kind of cementing cement head Quick joint hoop, solves cementing cement head and is connected hard problem with the special thread button-type of sleeve pipe or casing coupling.
The technical solution of the utility model is achieved in the following ways:
The utility model comprises joint for sealing connecting, clip body, lip ring, snap ring assembly and lock pin, it is characterized in that: joint for sealing connecting is threaded with the clip body, lip ring is located at the inner chamber place of joint for sealing connecting bottom, the casing coupling of sleeve pipe tubing string upper top packs in the clip body, seal between casing coupling upper surface and the annular confidential paper, the design of snap ring assembly is in the bottom in external week of clip, top is stuck on the clip body, the bottom is stuck on the lower end annular end face of casing coupling, by lock pin locking snap ring assembly.
Joint for sealing connecting is made as tubular, and top is provided with the male thread that is connected with cementing cement head, and the bottom is provided with the male thread that is connected with the clip body, is provided with one section extension diameter section in the bottom week.
The clip body is made as tubular, and the top internal diameter is greater than the bottom internal diameter, and top is provided with the box thread that is connected with joint for sealing connecting, and the bottom periphery is provided with the snap ring groove of snap ring assembly, and periphery is provided with rotary handle.
Lip ring is made as cylindrical, and upper periphery is provided with sealing ring, and lower, outer perimeter is provided with necking segment, is provided with Gask-O-Seal in the undergauge section.
The snap ring assembly is comprised of button type two lobe snap rings, the lock pin that is fixedly connected with the bearing pin of two lobe snap rings, one end and fixes the two lobe snap ring other ends, convex-concave button type engaging lug is established at two lobe snap ring two ends, the engaging lug of one end is provided with pin shaft hole, and the engaging lug of the other end is provided with the lock shaft hole.
Compared with the prior art the utility model has the following advantages:
1, main body has adopted the high-strength alloy structural iron, and is high pressure resistant, and the life-span is long;
2, clip is packed into behind the box cupling, rotates to an angle just to connect completely with the pipe series winding, and operation is simple and reliable, greatly improves well cementation efficient.
3, all sleeve pipes need only measure-alike, no matter which kind of button-type can connect.
