The Third Brigade of Downhole Operations Branch uses the ultra-high temperature heat pump unit with oil-contaminated water to extract heat from the low-temperature oilfield injection water produced in the oilfield production, heat the office and family area, and provide hot water to the staff bath. At present, the injection of cryogenic oil field has become oil-field-specific, valuable, huge renewable energy. A large number of low-temperature oilfield injection water produced during oil field production is usually treated and injected back into the ground, and the heat of 36 ° C. to 42 ° C. is wasted. Oily water ultra-high temperature heat pump unit using heat pump technology, low temperature oil field can be injected into the water heat energy collected, after the energy conversion for heating oilfield enterprises, with hot and provide hot water. Previously, the operation of the third brigade burning residue oil heating, not only costly, but also emit harmful gases such as carbon dioxide, causing great pollution to the air. Taking the heating period in 2006 as an example, about 2,000 tons of residue is burned in the whole heating period, equivalent to about 5.5 million yuan. However, it is estimated that the annual electricity consumption will be about 2.5 million yuan with heating of new units, and the heating cost will be greatly reduced. As the oily wastewater ultra-high temperature heat pump unit is a non-pressure vessel, the control system is fully automated, greatly reducing the labor intensity of workers and achieving heating safety. At the same time, the whole heating process adopts electric-driven heat pump unit, which not only saves a large amount of disposable energy but also realizes zero-emission of toxic and harmful gases such as carbon dioxide and sulfur dioxide and has obvious environmental benefits. The Milling Machine was originally a horizontal milling machine created by American E. Whitney in 1818.In order to mill the spiral groove of the twist drill, American J.R. Brown created the first universal milling machine in 1862, which is the prototype of the milling machine for the lifting platform.The portal milling machine appeared around 1884.Semi-automatic milling machines appeared in the 1920s, and the workbench used the stops to perform automatic conversion of [feed-fast" or [fast-feed".After 1950, milling machines developed rapidly in control systems, and the application of digital control greatly improved the automation of milling machines.Especially after the 1970s, the digital control system and automatic tool change system of the microprocessor were applied on the milling machine, which expanded the processing range of the milling machine and improved the machining accuracy and efficiency.As the mechanization process intensified, CNC programming began to be widely used in machine tool operations, which greatly released the labor force.CNC programming milling machines will gradually replace manual operations.The requirements for employees will also be higher and higher, and of course the efficiency will be higher and higher.
