Anti-sand screen pipe for deep well

Abstract

An anti-sand screen pipe for a deep well comprises a base pipe, a screen mesh, a stopping block and a joint; the screen mesh is arranged outside the base pipe; the screen mesh is fixed on the base pipe in a welding mode; the stopping block is arranged on the outer side of the screen mesh; the screen mesh is a stainless steel screen mesh which is in a circular hole shape; a corrosion resistant layer is stored in the base pipe; the joint is provided with connection threads. According to the layer of screen mesh is arranged outside the base pipe and accordingly the sand cannot enter an oil well pump and accordingly the damage to the oil well pump can be avoided, the oil production of the oil field cannot be affected, the inspection cycle of the oil well pump can be reduced, and the production cost of the oil field is greatly reduced; meanwhile the threaded connection of the joint is adopted and accordingly the connection of an oil pipe and the screen pipe can be convenient, the sealing performance of the connection position of the oil pipe and the screen pipe is improved, the leakage of the crude oil is avoided, and the oil production of the oil field is improved; the corrosion resistant layer is arranged in the base pipe and accordingly the corrosion resistance of the base pipe can be extended, the base pipe cannot crack, the leakage of the oil cannot be caused, and the energy is saved.

Description

technical field [0001] The invention relates to a deep well sand prevention screen. Background technique [0002] With the continuous development of oil fields, more and more oil well pumps are put into the production of oil fields. Many oil well pumps need to be buried deeply in the ground for oil pumping operations. In this way, sand and gravel will often enter the oil well pumps, resulting in The failure of the oil pump affects the oil production of the oil field. At present, the connection between the sand control screen and the oil pipe is connected through a coupling. This connection often leads to leakage, resulting in a large amount of waste of crude oil, resulting Soil pollution affects the oil production of the oil field and leads to economic losses. The base pipe is often eroded by oil during the transportation of oil, resulting in cracks in the base pipe. Such cracks will cause crude oil to leak and pollute the surrounding area. environment, which also causes a ...

[0002] With the continuous development of oil fields, more and more oil well pumps are put into the production of oil fields. Many oil well pumps need to be buried deeply in the ground for oil pumping operations. In this way, sand and gravel will often enter the oil well pumps, resulting in The failure of the oil pump affects the oil production of the oil field. At present, the connection between the sand control screen and the oil pipe is connected through a coupling. This connection often leads to leakage, resulting in a large amount of waste of crude oil, resulting Soil pollution affects the oil production of the oil field and leads to economic losses. The base pipe is often eroded by oil during the transportation of oil, resulting in cracks in the base pipe. Such cracks will cause crude oil to leak and pollute the surrounding area. environment, which also causes a waste of resources, which is not conducive to the long-term development of the oil field. Such a situation will affect the service life of the base pipe, shorten the service life of the base pipe, increase the economic burden of the oil field, and require excessive capital investment into oil pipeline infrastructure
