Dedicated oil adjusting paraffin removal device for rodless oil production and device with paraffin removal device

Abstract

The invention discloses a dedicated oil adjusting paraffin removing device for rodless oil production and a device with the dedicated oil paraffin removal device. The dedicated oil adjusting paraffin removing device comprises a copper conductor, and structurally comprises the copper conductor, a polyimide film, fluoroplastic, glass fiber cloth, a stainless steel heating tube and an insulating heat-conducting jacket arranged from inside out respectively; the right end of the copper conductor is electrically connected with the right end of the stainless steel heating tube; and the insulating heat-conducting jacket is arranged at the right end of the electric joint of the right end of the copper conductor and the right end of the stainless steel heating tube. The device with the dedicated oil adjusting paraffin removing device for rodless oil production comprises the dedicated oil adjusting paraffin removing device for rodless oil production and a medium-frequency inverter, wherein the medium-frequency inverter is electrically connected with the upper end of the copper conductor of the dedicated oil adjusting paraffin removing device for rodless oil production and the upper end of the stainless steel heating tube. The dedicated oil adjusting paraffin removal device for rodless oil production is mounted in a rodless oil production pump, so that higher paraffin removal efficiency is achieved, paraffin accumulation in the rodless oil production pump and an oil production pipe is avoided, oil production efficiency is improved, paraffin removal cost is lowered, and great convenience is brought to maintenance of oil production equipment.

Description

technical field [0001] The invention relates to a special oil-adjusting and wax-removing device for rodless oil production and a device with the wax remover, which is mainly used in the process of oil-adjusting and wax-removing for rodless oil production wells. Background technique [0002] Paraffin or paraffin deposits are present in various grades of crude oil. During production, without additional heating, the temperature of the oil decreases from the time it leaves the formation until the crude reaches the refinery. When the temperature drops below the crystallization point of paraffin wax, the paraffin wax is precipitated out of crude oil, and after forming crystals, it gradually grows larger and deposits inside oil production pipelines or oil well casings, inside processing and separation equipment, and inside oil storage equipment. If an oil well has excess paraffin deposits, it can restrict the flow of crude oil and eventually block the pipeline completely. Another...

Problems solved by technology

Another problem that is often overlooked occurs when small paraffinic micelles such as microinverse emulsions are suspended in produced water: when these paraffinic produced waters are reinjected into the formation, the paraffins contained can plug the tubing Perforations and throats, even plugged formations

Therefore, when the deposition of paraffin is serious, the oil well needs to be shut down for maintenance, which directly affects the oil recovery efficiency.

[0003] Electric submersible pumps, submersible direct drive pumps, reciprocating pumps, etc. are often used in rodless oil production. Due to the deposition of paraffin, frequent shutdowns are required to scrape the wax. The construction is complicated and expensive, which brings a lot of inconvenience to oil production and affects oil recovery efficiency.
