Abstract
A heating system preventing wax deposition of oil production well tubes comprises a microwave guide tube, a microwave generator, a wellhead device pipeline equipped with a valve, and a tube-casing annular space between a tube and a casing. The microwave guide tube is mounted inside the wellhead device pipeline connected with the casing and communicated with the tube-casing annular space. The front section of the microwave guide tube is connected with a microwave transmitting end of the microwave generator, while the rear section is equipped with a reflection board which is positioned inside the tube-casing annular space. The microwave generator transmits microwave through the microwave guide tube to the reflection board on the rear section of the microwave guide tube, the microwave is reflected by the reflection board into the tube-casing annular space for further microwave heating, the wall of the tube is heated by continuously heating steam in the tube-casing annular space and moisture at the well bottom, thereby preventing wax from coagulating on an inner surface of the tube during crude oil extraction, utilizing heat to remove the wax on the wall of the tube and a surface of a sucker rod, and increasing yield of crude oil.
Description
Technical field
