Architecture of Sandstone Bodies of Paleogene Shahejie Formation in Northern Qikou Sag, Northeast China

引用

Journal of Earth Science 2017年第6期28卷 1078-1085页

作者： Hua Wang Si Chen Chuanyan Huang Xianbin Shi Yuantao Liao Faculty of Earth Resources China University of Geosciences Wuhan 430074 China Key Laboratory of Tectonics and petroleum Resources Ministry of Education China University of Geosciences Wuhan 430074 China Hubei Geological Survey Institute Wuhan 430034 China

The conception of special geologic bodies has been applied in this study to define and illustrate economic oil and gas reservoirs in sandbodies, which is helpful for hydrocarbon forecast and exploration. Using the comprehensive analysis of drilling, logging, seismic, seismic attribute extraction, and logging constrained inversion in 3D data volume, the special geologic bodies of the Shahejie Formation（Ps^1s） in northern Qikou sag, which have good hydrocarbon potential, are identified and described under the constraint of sequence stratigraphic framework. The dimensions, geometry, and spatial distribution features of the special geologic bodies, as well as their inner architectures and sequence-structure patterns, are also ascertained. The geologic bodies evolved from relative centralization in the middle part of the lacustrine basin in the early stage of Ps1~s Formation, to several dispersive isolated parts in the later stage. This shows a small cycle interval（~2.5 Ma） at the end of the whole transgressive depositional process of Ps1（~7.5 Ma） during the expansion of the lake and relative lake level rise, with the control of sediments supply and fault-related subsidence, which effect the evolution of the sedimentary system. According to the relevance and regularity of the geologic bodies＇ development, different types of potential profitable reservoir traps, including the lithologic lenticular traps, lithologic updip pinchout traps, and structural-lithologic composite traps, can be preserved in the study area. In addition, the internal architecture models provide scientific basis for further hydrocarbon exploration in the frontier basin without enough data.

China Oil & Gas 2005年第3期12卷 38-39页

作者： Sun Weizheng CNOOC Bohai company

Floating production, storage and offloading unit （FPSO）, a single engineering unit with the largest investment in offshore petroleum industry, carries on board various facilities including oil production, storage and export, as well as living and power. It is used to process and storage crude oil, which will be shipped regularly by tankers to various places. Along with the intensification of offshore exploration and development in China, China National Offshore Oil Corporation （CNOOC） has been working hard to expand its FPSO industry scope. Now, 14 FPSO units have been put into operation in 16 oilfields, of which 13 FPSO units operate in China＇s offshore and 1 in Java offshore in Indonesia. China＇s FPSO technology has reached international advanced level and China has become the largest manufacturer and user of FPSO in the world, with both the number and gross tonnage of FPSO units ranking the top of the world.

Evolution of Ordovician YJ1X ultra-deep oil reservoir in the Yuecan oilfield, tarim Basin, NW China

Based on a combined in-situ calcite U-Pb dating, molecular geochemical correlations of reservoir oil and extract from reservoir rocks, and fluid inclusion analysis, the charge and evolution history of the YJ1X ultra-deep oil reservoir of the Ordovician Yijianfang Formation in the southwestern part of the Tabei Uplift has been determined systematically.(1) The reservoir oil, free oil and inclusion oil have similar geochemical characteristics and are presumably derived from marine source rock deposited in similar sedimentary environment.(2) The reservoir oil, free oil and inclusion oil have similar maturities with calculated equivalent vitrinite reflectance values in the range of 0.80%-0.96%.(3) Two types(Group Ⅰ and Ⅱ) of oil inclusion assemblages(OIAs) have been identified in the reservoir, of which Group Ⅰ represents the original gas-saturated oil entering the trap during the initial oil charge, whereas Group Ⅱ represents undersaturated residual oil retained in the reservoir after minor leakage of light hydrocarbon.(4) The reservoir experienced oil charge only once during the Early Devonian around 425 Ma and has been well preserved after the minor light hydrocarbon leakage in the Middle Devonian. The study shows that there may be old oil and gas accumulations in ultra-deep strata of petroliferous basins with well-developed caprock and stable tectonic background.

Analysis and Opinions on How PetroChina Markets Its Equity Oil

引用

China Oil & Gas 2002年第4期9卷 50-52页

作者： Ren XiaoruPetroChina Oil Refining and Marketing company PetroChina Oil Refining and Marketing company

In the past five years, PeroChina has signed seven contracts for overseas petroleum exploration and development. Those projects are scattering in seven countries in three main regions - Central Asia and Russia, the Middle East and North Africa as well as South America. Currently, PeroChina has obtained the equity recoverable reserves of 460 million tons worldwide with the annual crude oil production reaching 13.5 million tons. In addition, PetroChina is making ambitious efforts to seek new opportunities in Asia-Pacific region and North America for increase of its equity oil from overseas business.
