This geological background resulted in characteristics such as many small fault blocks, multiple oil-bearing formations, scattered oil distribution, mini- to small-sized reservoirs, and difficulties in exploration. Aimed at such characteristics, an effective exploration strategy was adopted, and the oil reserves, production and economic benefits of the Jiangsu oilfield were significantly increased. This exploration strategy included understanding the hydrocarbon generation mechanism of source rocks, progressive evaluation of oil resources, comprehensive research on the faulted systems, the distribution of oil reservoirs and their controlling factors. The techniques used included integration of acquisition, processing and interpretation with 3-D seismics as the core technology, trap description and evaluation, directional drilling and cluster drilling, integration of cuttings logging, gas chromatographic logging and geochemical logging, and integration of early reservoir description and progressive exploration and development. This strategy could be guidance for other complex fault blocks.展开更多

As a result, both social enterprises and individuals have paid unprecedented attention to environmental protection and energy conservation. In the chemical industry, it has always been known for its high energy consumption and high pollution. Therefore, how to promote the application of energy-saving and consumption-reducing technologies in chemical processes has become an important issue of concern to chemical enterprises at this stage. The common energy-saving and consumption-reducing technologies in chemical process are analyzed, which can provide reference for the chemical industry to improve the process equipment and production process.展开更多
