Oil well fracturing ball injector

Abstract

The invention relates to the technical field of fracturing ball injectors, and discloses an oil well fracturing ball injector. The oil well fracturing ball injector comprises a box body, a ball injection pipe fixedly communicates with the interior of the box body, a ball injection channel is formed inside the ball injection pipe, the side face of the ball injection pipe is movably sleeved with a check block, a first installing frame is fixedly connected to the side face of the ball injection pipe, and a first telescopic rod is fixedly connected to the inner side face of the first installing frame. According to the oil well fracturing ball injector, a communicating sleeve fixedly communicates with the side face of a ball injecting pipe, a discharging hole and a selecting hole are formed in the bottom face of the communicating sleeve, a second telescopic rod on the digging side of a box body is connected into the communicating sleeve in a sleeve mode, a magnetic suction head on the end face of the communicating sleeve is utilized, the magnetic suction head is powered off and loses magnetism, when blocking balls with a proper diameter are selected, the unsuitable blocking balls are attracted and pulled to the discharging hole to be released in a power-off mode after being powered on, the selection effect of the blocking balls is improved, the blocking balls can adapt to pipelines conveniently, and the using effect is good.

Description

technical field [0001] The invention relates to the technical field of fracturing ball launchers, in particular to a fracturing ball launcher for oil wells. Background technique [0002] In order to extract oil, the holes drilled according to the well layout system of the oilfield development plan are the channels through which the oil rises from the bottom of the well to the wellhead. And inject oil well cement into the annular space between the casing and the well wall to maintain the well wall and seal the oil, gas, and water layers, and then use the perforating gun to open the oil layer according to the requirements of oil field development to form a channel, and then enter the tubing to A suitable induction method is to raise the oil from the bottom of the oil well to the head of the well. Ball throwers are usually used in oil well production. Ball throwers are commonly used equipment in layered fracturing construction in oil recovery acidizing fracturing technology, es...

Problems solved by technology

[0003]The existing fracturing balls for oil wells, in the process of use, due to the different diameters of the plugging balls, adapt to different pipe diameters, and block different pipes Usually, different diameters of clogging balls are needed, but the diameters of the clogging balls in the pitching channel do not match in the actual operation process, and it needs to be selected before pitching to ensure that the diameter of the pitching ball is accurate. Sorting the clogging balls in the predetermined clogging order, additional sorting operations are added, and the use effect is not good

[0004] In addition, in the process of using the existing fracturing balls for oil wells, since there are a certain number of clogged balls in the pitching channel, the clogged balls at the bottom are released At the same time, it is required to release the stopper of the bottom jammed ball to slide quickly, so as to avoid the upper jammed ball from falling, and errors are easy to exist in the process of collecting and throwing the ball. Poor, use poorly

[0005]On the other hand, in the process of using the existing fracturing balls for oil wells, because the clogging balls are frequently used, there are some diameters in the actual use process. The wear is serious and it is not suitable for the throwing operation. However, the existing ball pitcher cannot effectively judge the quality of the blocked ball before pitching, and it cannot be discharged in time and effectively when there is a problem with the blocked ball. The wear and tear in the pitching channel It is troublesome to clear the clogged ball, and the effect is poor
