Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] The implementation of the present invention will be described in detail below in conjunction with specific embodiments.

[0029] Such as figure 1 As shown, the cementing ball seat provided in this embodiment includes a ball seat main body 1 and a basketball seat 2 .

[0030] Such as figure 1 As shown, the ball seat main body 1 has a tubular shape as a whole, and the ball seat main body 1 includes a shear seat 11 which is hollow inside and has openings at both ends. The shear seat 11 is used to cooperate with the outer sphere 5 for crimping.

[0031] Such as figure 1 As shown, the basket...

Abstract

The invention relates to the field of cementing in petroleum and natural gas engineering, and discloses a cementing ball seat, comprising a ball seat main body and a ball basket seat. It is connected with the main body of the ball seat to keep the two relatively fixed, and the ball basket seat is provided with an accommodating groove for accommodating the shear seat after being crushed and broken. Compared with the prior art, because the cementing ball seat is provided with a ball basket seat, the ball basket seat is provided with an accommodating groove, and the shear seat falls into the accommodating groove of the ball basket seat after being broken by the crumple pressure, so it can be Effectively prevent the shear seat from falling to the floating hoop and causing damage to the floating hoop, thereby improving the safe use factor of the floating hoop in the construction process and ensuring the quality of cementing construction.

Description

technical field [0001] The invention relates to the cementing field in petroleum and natural gas engineering, in particular to a cementing ball seat. Background technique [0002] With the development of the petroleum industry and the development of oil fields, there are more and more extended-reach wells. How to ensure the quality of liner cementing of these complex wells is a major problem faced by field operators. [0003] At present, domestic liner cementing tools are usually hydraulic liner hangers. In the cementing process, in order to block the pressure channel and generate hydraulic pressure to hang the hanger, it is necessary to perform ball-throwing lame pressure operation. The cementing ball seat is used as the seating nipple of the outer sphere, and its performance directly affects the cementing quality of the entire liner. In the existing conventional liner cementing process, the position of the cementing ball seat is usually designed at the bottom of the line...
