With the construction of oil and gas pipelines,despite of a variety of anti-corrosion and preventive measures,the pipeline leakage still occurs.

It is difficult for China to recognize, measure, record and report the production activity of oil and gas industry.

The study of oil and gas accounting in China started in the 1980's, which is, on the whole, divided into blankness period before the 1980's, the translation period of the 1980's to the middle 1990's, and deeply systematic research period after the middle 1990's.

Oil and natural gas are the national important energy resources.

Based on the factors including supply and demand,transportation,cataclysm,economy and environment,oil & gas security pre-warning index system was established.

The Ni-P alloy electroless plating coating was prepared on the inner wall of petroleum gas transportation pipeline and container,and corrosion resistance of coated pipeline and container to CO2 was studied.

A lot of wastes were generated during the course of petroleum and natural gas exploration and production(E&P).

Six sulfur compounds in high sour petroleum and natural gas were determined qualitatively and quantitatively using gas chromatography equipped with capillary column and FPD(Flame Photometric Detector).
