Qinshui basin hosts marine-continental facies in the North China Craton, ranks top in coal-bed methane exploration and development in China. This paper, based on its total content of organic carbon (TOC), orgianic maturity, minerals, fissures, porosity, permeability and gas content, concludes that Qinshui basin, although thin in single shale-mud bed of marine-continental facies, hosts a good gas reservoir-forming condition from its high organic maturity at gas generation bloom, especially high content of brittle minerals which can easily form natural fissures and inducing cracks by external forces, favorable for latter extracting. It’s practical to extract shale gas and coal-bed methane together. This paper gives an outlook for Qinshui basin’s shale gas resources.

Based on the observation and study of the samples of 3^#  and 15^#  coal seams in ten coal mines in the south of Qinshui Basin with optical microscope and scan electron microscope, the authors expound the characteristics of coal microfracture and its correlations with coal maceral composition. The study shows that the fractures are commonly present in both 3^# and 15^# coal seams. They are more developed in 15^# coal seam than in 3^# coal seam, but some fractures in 15^#  coal seam are filled. Fractures, including endogenic fracture and exogenous fracture, are mostly developed in vitrinite, among which telocollinite is primary and desmocollinite the second. In inertinite, fractures are primarily developed in fusinite and are mainly of tensional fractures. Endogenic fractures are not developed in inertinite of high rank coal. The fracture is controlled by coal maceral composition in the procedure of coalification through the release of water adopted in paludification, the combined action of composition structure and generated gas, and mechanical behaviors.

Coal mines in Northern China are becoming exhausted in the shallow after a long period of mining, so it is a necessity to look for coal in the deep. This paper summarizes systematically the distribution of coal resources and deep potential in five provinces in the east of northern China, analyzes the change trend of coal beds in the deep, and predicts the prospecting in the existing coal mines. The deep coal resources (-800~-1500m) are of huge potential, 2~4 times the shallow (above-800m) in Hebei, Shandong, Jiangsu and Anhui. Gas coal fields are generally located in the shallow while coking coal fields are in the deep. The future prospecting lies in the deep and outskirts of existing mines, Coal beds under the large thrusts and complicated structures are of economic values. A detailed geological exploration and development planning must be completed due to a complicated geology in the deep, giving priority in developing those of stable and quality coal beds by  verifying the deep structures in order to avoid severe geological disasters.

This paper gives a brief introduction to the foreign marine oil-gas exploration methods. By studying the marine oil-gas exploration experiences, this paper gets an understanding of geophysical methods which are applied in big foreign oil companies, discusses the marine oil-field exploration modes, offering a reference to develop the marine oil-gas in the future.

The west slop in Songliao basin abounds in oil sand resources, whose formation has a close relation to the geology, structure and oil-gas enrichment in Songliao basin. Large quantity of sand body provide a reservoir for crude oil, faults and strata erosion form the channel for oil to migrate, and the compact mudstone keeps crude oil from volatilizing, oxidizing and biodegradation. The abundant oil sources in Songliao basin are another necessary factor to form the oil sands. This paper presents that the Tumuji oil sands are largely controlled by sedimentary facies, reservoir-caprock, local peak, lithological change uparwards, surface hydrological dynamics and  gross oil-gas migration quantity.

The oilshale resources are very abundant with its reserve triple to oil reserve in the world. As the oil-gas resources become less and less, it is economic and feasible to mine the oilshales. This paper compares the traditional oilshale mining technology (dry distillation and fluidized combustion for power generation) and Shell's ICP (Insitu Conversion Process), with results indication ICP is much better in environment, cost and products. So China shall develop ICP to face the challenging energy consumption.
