Abstract

The utility model discloses a lower sand blower for oil exploitation, which comprises a body and a cap. The lower extreme hole of body is M54x 2's screw thread box, and the nut outer wall is equipped with the external screw thread, the screw thread box of the lower extreme of body and the external screw thread meshing of nut are connected. This novel lower sand blaster can be according to customer's core requirement, according to the design life of sand blaster in the pit promptly, adjust the production material and the production technology of and cap, should and the cap adopts soluble material, and through strict inspection and test, satisfy the total requirement of sand blaster accumulative total operating time in the pit that the customer set up in advance, this soluble material can be adjusted in real time according to the well condition, simultaneously, the internal diameter of this type sand blaster is through precision finishing, with the internal body reasonable cooperation of sand blaster, can also play the effect of throttle, the oil is opened and is adopted this lower sand blaster, work efficiency when can greatly strengthen production, improve life by a wide margin.

Description

Lower sand blower for oil exploitation

Technical Field

The utility model relates to a sand blaster technical field specifically is a sand blaster under oil exploitation.

Background

Along with the development of present oil exploitation technique, the sandblaster is more and more extensive by the use when carrying out fracturing construction, it can make the rock in oil reservoir or near area form the crack to spray fracturing fluid through the sandblaster, can reduce the pressure during fracturing construction, thereby reduce the construction risk, wherein, the speed of spraying fracturing fluid is faster, the corresponding crack that forms is also bigger, the pressure reduction effect is also more obvious, consequently, how to design the sandblaster is the key that improves pressure reduction efficiency, and current sandblaster when using, fracturing fluid sprays at a high speed down, cause very big wearing and tearing to seal cover and sandblast hole, life is shorter. Therefore, a lower sand blaster for oil exploitation is provided, and the lower sand blaster is matched with a sand blaster (side blasting).

Meanwhile, the nozzle of the lower sand blower is required to be time-efficient, and the nozzle can be dissolved to be completely ablated in a specific time. The nozzle of the sand blaster is also required to play a throttling role. Therefore, a novel lower sand blaster for oil exploitation is provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a sand blaster under oil exploitation to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a sand blaster under oil division adoption, includes the body and the cap, the upper end hole of body is the beautiful system tapering screw thread box of standard, and the body is connected through the screw thread box of upper end and standard oil pipe's external screw thread meshing, the lower extreme hole of body is M54x 2's screw thread box, and the cap outer wall is equipped with the external screw thread, the screw thread box of the lower extreme of body and the external screw thread meshing of cap are connected.

The union cap is composed of a soluble material.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses the body and the cap be a special design, and the cap is a material and the very special material of component, independently develops, for novel original design, and the cap is that a soluble material constitutes. After the well is worked, the soluble material can be selected for use according to different well conditions. Dissolve within a preset time and open the channel. Not only plays a role of throttling, but also can control the opening time of the downward channel.
