The output of tight oil of the USA in 2016 was 220 million tons. According to the statistics of EIA, China has abundant tight oil resources, and its reserves rank No. 3 in the world. In the current situation of continuously low oil prices, through the technical progress and optimized management, the development costs of tight oil of the USA are continuously reduced, and the cost-effective development has been successfully realized. By contrast, China still has to carry out the further exploration in such aspects as policy guidance, understanding of tight oil resources, related technologies and management models. At present, through the positive exploration and practice, some oil fields in China have frist realized the cost-effective development of tight oil. By the summarization of existing successful experience and the study of advanced technologies of the USA in tight oil development, the sound engineering management system suitable for the development of tight oil resource in China is established, and great efforts should be exerted to realize the large-scale, cost-effective development of tight oil resources as soon as possible.展开更多

A 3D simulation design of comprehensive testing system for detecting strata mining-induced fractures on surface with radon gas (CTSR) was carried out by using a large-scale 3D solid model design software Pro/Engineer (Pro/E), which overcame three main disadvantages of ''static design thought, 2D planar design and heavy workload for remodification design'' on exiting design for mining engineering test systems. Meanwhile, based on the simulation design results of Pro/E software, the sta- bility of the jack-screw pressure bar for the key component in CTSR was checked with a material mechan- ics theory, which provided a reliable basis for materials selection during the latter machining process.展开更多
