Description
Technical Field
The utility model belongs to the technical field of petroleum drilling and underground operation, and particularly relates to a weighted valve opening ball.
Background
Taking the bypass system activated for multiple times as an example, the bypass system can not be opened by the pump of the valve ball in place under the influence of common valve ball, slurry density and drilling inclination angle factors. If the density of the slurry is too high, the buoyancy is too high in the descending process of the common valve opening ball, so that the valve opening ball cannot reach a preset position; after the well depth, a common valve opening ball sometimes passes through a ball seat after pumping, and a bypass valve system cannot be opened; when the inclination angle of the drilling well is overlarge or the drilling well meets a horizontal well, the valve opening ball is generally aggravated, and is easy to be blocked or blocked due to the structure and the volume, so that the valve opening times are reduced, and the risks of underground complexity, accidents, well control and the like are increased.
The steel ball manufacturing method has the advantages that the steel ball manufacturing method of the rubber ring embedded with the dart is adopted to solve the problems, and the steel ball manufacturing method is difficult to control, complex in structure, high in consumable materials and not beneficial to actual production requirements;
therefore, how to provide a weighted valve opening ball with a bypass system which has a simple structure, less material consumption and small volume and can be activated for multiple times is a problem to be solved by the person skilled in the art.
Disclosure of Invention
The utility model provides the heavy valve opening ball of the bypass system, which has the advantages of simple structure, less material consumption, small volume, recycling of the gravity ball and capability of increasing multiple activations.

The shell is provided with a hollow cavity, and the outer wall of the shell is provided with a notch communicated with the hollow cavity. A gravity ball is located in the hollow cavity. The end cover is installed in the notch, the density of gravity ball is greater than the density of end cover.
Optionally, the annular inner wall of the notch is provided with an internal thread, and the outer side wall of the end cover is provided with an external thread matched with the internal thread.
Optionally, the gravity ball is made of steel.
Optionally, the housing is a sphere.
Compared with the prior art, the utility model provides the weighted valve opening ball, when the weighted valve opening ball works, the weighted valve opening ball is directly put into a well, and directly slides to the position of the ball seat of the bypass system due to the large density of the weighted valve opening ball, when the drilling inclination angle is overlarge or the ball seat of the bypass system is horizontal, the ball seat of the bypass system can be conveniently pumped due to the circular ball body of the weighted valve opening ball, then plugging liquid is pumped, and when the pressure is larger than the shearing pressure of the weighted valve opening ball, the weighted valve opening ball can pass through the ball seat and fall into the ball basket; the accessory provided by the utility model not only can realize recycling and repeated utilization, but also can increase a bypass system activated for multiple times, and has the advantages of simple structure, less material consumption, small volume, simple and convenient operation method and high application value.
