T19 -- The Developing Petroleum Industry

China is one of the earliest countries that discovered and used petroleum in the world.  Before 1949, China's petroleum industry was underdeveloped and crude oil was mainly imported from foreign countries.

After the discoveries of Daqing oilfield (Heilongjian Province) in 1959 and Shengli oilfield (Yellow River delta, Shandong Province) in 1961, China's petroleum industry started development.  As other oilfields in the countries were discovered and begun operations, the petroleum industry has made giant progress.

A set of six stamps was released on January 31, 1978, reflecting the development of the petroleum industry in China.

(6-1) 8 fen, Monolithic movable drilling rig  钻机整体搬家
(6-2) 8 fen, Oil extraction  采油
(6-3) 8 fen, Construction of oil field  油田建设
(6-4) 8 fen, Oil refining  炼油
(6-5) 8 fen, Oil transportation  输油
(6-6) 20 fen, Marine drilling  海上钻探

(6-1)【Monolithic mobile drilling rig】A drilling rig is a machine which creates holes in the ground, for exploration and extraction of crude oil.  The stamp showed a mobile drilling rig, which is a machine that can move from well to well, enabling mechanization of oil exploration and extraction.

(6-2)【Oil extraction】 The extraction of petroleum is the process by which crude oil is extracted and removed from the earth.  The stamp showed a near-shore oil extraction facility.

(6-3)【Construction of oil field】 Oil field construction is essential for the petroleum industry.  The stamp showed construction of  new pipe lines at Daqing oilfield.  The red piping stretching to outside the stamp field symbolizes supply of oil from the oilfield to the rest of the nation.

(6-4)【Oil refining】 Oil refining is an industrial process where crude oil is processed and refined into more useful products such as diesel fuel, gasoline, petroleum naphtha, asphalt, heating oil, kerosene, liquefied petroleum gas, etc.  The stamp showed a large, sprawling oil refining complex, with river, bridge and mountain, which enriched the stamp design. 

(6-5)【Oil transportation】 Oil transportation is an essential part of the petroleum industry.  The stamp showed a port facility built to receive, store, load and off-load oil.  Long delivery pipes are showed connecting and transferring oil to giant oil tankers offshore.

(6-6)【Marine drilling】 After Shengli oilfield begun development in 1964, it showed vast potential offshore and marine oil exploration and extraction became a new field of development.  The stamp design showed an oil rig on the right and an oil tanker at an oil rig further away.  A rising sun on the horizon symbolizes a bight future on marine oilfield development.
