Stress corrosion cracking behavior of buried oil and gas pipeline steel under the coexistence of magnetic field and sulfate-reducing bacteria
《Petroleum Science》2024年第2期1320-1332,共13页Jian-Yu He Fei Xie Dan Wang Guang-Xin Liu Ming Wu Yue Qin 
supported by the National Science Foundation of China(Grant numbers 52274062);Natural Science Foundation of Liaoning Province(Grant numbers 2022-MS-362)。
Magnetic field and microorganisms are important factors influencing the stress corrosion cracking(SCC)of buried oil and gas pipelines. Once SCC occurs in buried pipelines, it will cause serious hazards to the soil env...

An approach to grading coalbed methane resources in China for the purpose of implementing a differential production subsidy
《Petroleum Science》2019年第2期447-457,共11页Liangyu Xia Yujie Yin Xin Yu Yuhua Zheng 
Financial support from the Ministry of Science and Technology of China (No. 2016ZX05042-002-004);Science Foundation of China University of Petroleum, Beijing (No. 2462015YQ0718)
The heterogeneity of coalbed methane(CBM) resources was not taken into account when the current indiscriminate subsidy policy was developed. In it, limited subsidy funds are given first to high-quality resources and e...
