As an important type of “conventional–unconventional orderly accumulation”, shale oil is mature stored in organic-rich shales with nano-scale pores. This paper analyzes and summarizes elementary petroleum geological issues concerning continental China, including sedimentary environment, reservoir space, geochemical features accumulation mechanism. Mainly deposited semi-deep to deep lake rich organic matter usually coexists other lithologies laminated texture, micron pores microfractures...
Continental shale oil has two types, low-medium maturity and medium-high maturity, they are different in terms of resource environment, potential, production methods technologies, industrial evaluation criteria. In addition, continental is from the tight United States. Scientific definition connotations these types great significance for promoting exploration “outside source” into “inside making it a strategic replacement future. The oils made clear this study. former refers to liquid...
Petroleum geology is evolving into two branches, conventional petroleum and unconventional geology, with the latter becoming a new theoretical frontier in industry. The core of hydrocarbon geological study based on identifying match between source rock, reservoir, caprock, migration, trap, preservation timing; evaluates if oil gas part continuous accumulation, where stress placed evaluation "lithology, physical properties, brittleness, oiliness, rock features, anisotropy" their...
Global petroleum exploration is currently undergoing a strategic shift from conventional to unconventional hydrocarbon resources. Unconventional hydrocarbons in tight reservoirs show characteristics distinct those of sources hosted structural and stratigraphic traps. The characteristic features include the following: source reservoir coexist; porosity permeability are ultra-low; nano-pore throats widely distributed; hydrocarbon-bearing bodies continuously there no obvious trap boundary;...
The features and exploration potential of the Permian tight oil in Junggar Basin were analyzed evaluated using outcrop, core geochemical data etc. Early-Mid is a saline lacustrine basin after residual sea closed, set hybrid sedimentation deep-lake dark mudstone dolomitic rock developed, high-quality source rocks dolomite are alternated. High quality mature stage next to reservoirs closely provide good conditions for accumulation proximal type. Tight mainly distributed centre slope region...
Continental shale oil is a general term for liquid hydrocarbons and many kinds of organic matter in continental organic-rich series with vitrinite reflectance more than 0.5% at buried depth 300 m, an important type source-rock gas. Based on the evolution model generation expulsion controlled by maturity, divided into two types: medium-high maturity medium-low maturity. (1) The China develop high-quality source rocks freshwater saltwater lacustrine facies, as well multiple types reservoirs,...
Based on the latest global conventional-unconventional petroleum development situation and conclusion of geology theory technology innovation in recent 10 years, connotation conventional unconventional "orderly accumulation" is formulated. This concept indicates that, occurs hydrocarbon supply direction petroleum, may appear outer space petroleum. Proper evaluation methods engineering are important to push co-development, finding thought from outer-source into inner-source. Unconventional...
In-situ conversion processing (ICP) of shale oil underground at the depth ranging from 300 m to 3 000 is a physical and chemical process caused by using horizontal drilling electric heating technology, which converts heavy oil, bitumen various organic matter into light gas in large scale, can be called “underground refinery”. ICP has several advantages as CO2 capture, recoverable resource potential quality hydrocarbon output. Based on geothermal evolution mechanism materials established...
By comparison of the types, geological characteristics and exploration technologies conventional unconventional hydrocarbon, this paper proposes concept “nano-hydrocarbon” regard nano-hydrocarbon as development direction oil gas industry in future. Nano-hydrocarbon refers to research production, by nano-technology, accumulated reservoir system nano-sized pore-throats. It is mainly distributed source rocks neighbouring tight reservoirs includes shale oil, gas, coal-bed methane, sandstone...
Large and extra-large oil/gas fields are mainly distributed in Tethys areas, passive margins, foreland thrust belts, craton basins the world. Unconventional slopes, basin (depression) centers, synclines, tundra. Since 21st century, major exploration discoveries across globe have been concentrated deep water area of carbonate rock, lithologic-stratigraphic zone, belt, mature area, new unconventional reservoir (field). These involve conventional resources. The oil geology stresses migration...
The new century has witnessed a strategic breakthrough in unconventional oil & gas. Hydrocarbon accumulated micro‐/nano‐scale pore throat shale systems become an important domain that could replace current gas resources. Unconventional plays increasingly role our energy demand. Tight gas, CBM, heavy and asphaltic sand have served as key of exploration development, with tight becoming ‘bright spot’ ‘hotspot’ domain. China made great breakthroughs resources, such progress shale, hydrate,...
The differences in organic matter abundance and rock composition between shale mudstone determine the discrepancy of their contributions to formation conventional oil/gas reservoirs. evaluation criteria source rocks are different future exploration self-sourced petroleum systems. Shales deposited deep/semi-deep lacustrine, with low sedimentation rate chemical depositions various degrees, while mudstones mostly formed shallow lacustrine/lakeside, high deposition density flow characteristics....
The evolution of pore structure in shales is affected by both the thermal organic matter (OM) and inorganic diagenesis, resulting a wide variety structures. This paper examines OM distribution lacustrine its influence on structure, describes process porosity development. principal findings are: (i) Three patterns are distinguished; laminated continuous distribution, clumped stellate scattered distribution. differences total carbon (TOC) content, free hydrocarbon content (S1), among these...
The self-sealing of caprocks plays a vital role in CO2 geological sequestration. However, the mechanisms by which distinctive mineral combinations and types caprock bring about are unclear. Studies with different rock promise to effectively identify capabilities cap rocks evaluate long-term safety This study focuses mainly on three caprocks, specifically shale Qingshankou Formation Songliao Basin, calcareous mudstone Da'anzhai Sichuan Yanchang Ordos Basin. applies key technology...
Based on distribution of oil and gas in the world, connotation characteristics "continuous" petroleum reservoirs are elaborated this paper. "Continuous" refer to unconventional trap existing a large-scale reservoir system, is continuous. The main geological as follows: located center slope basin, rich locally; mainly reservoirs; traps have no clear boundaries; self-generating self-preserving; primary migration; accumulated by diffusion buoyancy limited; non-Darcy flow; poor oil-water...
