The utility model has simple and convenient installation and operation, not only prevents the pipeline arranged in the downstream well from scaling, but also greatly reduces the corrosion under the scale and increases the economic benefit; in addition, the service life of the oil well and pipeline equipment is prolonged, the maintenance operation of the oil well is reduced, and the production cost is greatly reduced.
Description
Technical Field
The utility model belongs to the technical field of petroleum engineering, especially, relate to scale control nipple joint in pit.
Background
With the rapid development of society, the demand of countries and people for energy is increasing day by day. The development of oil fields in various fields is continuously advanced, and the importance of exploiting onshore and offshore oil is self-evident, so that the economic benefit of an oil well is more important. For an oil well with high mineralization, due to the fact that the content of scaling ions is high, frequent scaling of a downhole pipe column causes various problems of blockage, increased transportation pressure, energy waste, corrosion under equipment scale and the like of the downhole pipe column; the problems not only increase the production cost of petroleum, but also bring great potential safety hazard to the underground due to scaling and under-deposit corrosion of the underground pipe column.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an underground scale control nipple joint to solve the technical problem of the easy scale deposit of the high oil well of degree of mineralization.
In order to realize the purpose, the utility model discloses a concrete technical scheme of scale control nipple joint in pit as follows:
a downhole subs, comprising: the upper joint is arranged on the short section, and the shell and the lower joint are sequentially arranged below the upper joint in a matched manner; wherein the content of the first and second substances,
the upper end of the shell is connected with the upper joint; a plurality of scale prevention sheets capable of loading ultra-precise micro-shock wave energy are arranged in the shell; and a plurality of O-shaped rings are sleeved in the shell.
Furthermore, the plurality of anti-scaling pieces are respectively of two semi-cylindrical structures and are fixedly connected to the periphery of the short section, the two semi-cylindrical structures after being fixedly connected form an integral cylindrical structure, and the anti-scaling pieces are protected by the shell.
Further, the plurality of anti-scale sheets are arranged outside the short section at intervals of a set distance.
Furthermore, the plurality of O-shaped rings are arranged at intervals at set distances and are respectively arranged at the upper end and the lower end of the short section.
Further, the O-shaped rings are made of rubber materials.
The utility model discloses an underground scale control nipple joint has following advantage:
the utility model has simple and convenient installation and operation, not only prevents the pipeline arranged in the downstream well from scaling, but also greatly reduces the corrosion under the scale and increases the economic benefit; in addition, the service life of the oil well and pipeline equipment is prolonged, the maintenance operation of the oil well is reduced, and the production cost is greatly reduced.

Detailed Description
In order to better understand the purpose, structure and function of the utility model, the following description is made in detail with reference to the accompanying drawings.
As shown in fig. 1-3, the present invention includes: the device comprises an upper joint 1 arranged on a short section, and a shell 2 and a lower joint 3 which are sequentially arranged below the upper joint 1 in a matching manner; wherein the content of the first and second substances,
the upper end of the shell 2 is connected with the upper joint 1 in a screw 4 mode; a plurality of scale prevention sheets 5 (three are arranged at set intervals in the embodiment) capable of loading ultra-precise micro-shock wave energy are arranged in the shell 2; and a plurality of O-rings 6 (three are provided at a set distance in this embodiment) are sleeved on the upper and lower ends in the housing 2.
The scale prevention pieces 5 are respectively of two semi-cylindrical structures and are fixedly connected to the periphery of the short section through the hexagon socket head cap screw, and the two fixedly connected semi-cylindrical structures form an integral cylindrical structure; the scale prevention sheet 5 is protected by the housing 2.
The plurality of anti-scale sheets 5 are arranged outside the short section at intervals, and the anti-scale sheets 5 can load ultra-precise micro-vibration wave energy.
The O-shaped rings 6 are arranged at intervals and are arranged at the upper end and the lower end of the short section respectively.
The O-rings 6 are made of rubber material.
During the use, will the utility model discloses with the installation of tubular column in the pit to be connected together, then the fluid through the scale control nipple joint in the tubular column, under the effect that the super fine microseism swung the wave, the physical characteristics of scaling ions such as calcium, magnesium, iron, barium, strontium of aquatic are changed to be difficult for adsorbing each other, the macromolecule group of water of scattering increases the solubility, reaches the purpose of scale removal scale control.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements.
