The structure of Circum-Tibetan Plateau Basin-Range System and the large gas provinces

Science China Earth Sciences 2013年第11期56卷 1853-1863页

作者： JIA ChengZao LI BenLiang LEI YongLiang CHEN ZhuXin research institute of petroleum exploration and Development PetroChina

Northward subduction of the Cenozoic Tethys ocean caused the convergence and collision of Eurasia-Indian Plates, resulting in the lower crust thickening, the upper crust thrusting, and the Qinghai-Tibet uplifting, and forming the plateau landscape. In company with uplifting and northward extruding of the Tibetan plateau, the contractional tectonic deformations persistently spread outward, building a gigantic basin-range system around the Tibetan plateau. This system is herein termed as the Cir- cure-Tibetan Plateau Basin-Range System, in which the global largest diffuse and the most energetic intra-continental defor- mations were involved, and populations of inheritance foreland basins or thrust belts were developed along the margins of an- cient cratonic plates due to the effects of the cratonic amalgamation, crust differentiation, orogen rejuvenation, and basin sub- sidence. There are three primary tectonic units in the Circum-Tibet Plateau Basin-Range System, which are the reactivated an- cient orogens, the foreland thrust belts, and the miniature cratonic basins. The Circum-Tibetan Plateau Basin-Range System is a gigantic deformation system and particular Himalayan tectonic domain in central-western China and is comparable to the Tibetan Plateau. In this system, northward and eastward developments of thrust deformations exhibit an arc-shaped area along the Kunlun-Altyn-Qilian-Longmenshan mountain belts, and further expand outward to the Altai-Yinshan-Luliangshan- Huayingshan mountain belts during the Late Cenozoic sustained collision of Indo-Asia. Intense intra-continental deformations lead ancient orogens to rejuvenate, young foreland basins to form in-between orogens and cratons, and thrusts to propagate from orogens to cratons in successive order. Driven by the Eurasia-Indian collision and its far field effects, both deformation and basin-range couplings in the arc-shaped area decrease from south to north. When a single basin-range unit is focused on, deforma

Geochemical Characteristics of the Source Rocks in Mesozoic Yanchang Formation,Central Ordos Basin

引用

Journal of Earth Science 2013年第5期24卷 804-814页

作者：林森虎袁选俊陶士振杨智吴松涛 research institute of petroleum exploration & Development PetroChina

The shale of Yanchang Formation in Upper Triassic is the most important source rock for the Mesozoic petroleum reserviors in Ordos Basin. Chang 7 and Chang 4＋5 members are the major source rock formation. Source rock samples, obtained from 22 cored wells in central Ordos Basin, were geochemically analyzed to determine the organic matter abundance, kerogen type and thermal maturity. Total organic carbon values ranged from 0.36% to 19.10%, 8.09% on average, in- dicating a good source rock potential. In this area, the shale is mature, as indicated by vitrinite re- flectance values. RockoEval data revealed that the samples are dominated by type II kerogen. Com- pare the Chang 7 and Chang 4＋5 members, which suggests that the Chang 7 shale has higher TOC, especially the highest lower Chang 7 members. The abundance of organic matter of Chang 4＋5 and Chang 7 members is both richest in southeast basin. The kerogen type of Chang 4＋5 and upper Chang 7 members is type II~, the counterpart of middle and lower Chang 7 member is type I. During the burial history, the total hydrocarbon-generating quantity of Chang 7 member is much more than that of Chang 4＋5 members.

In order to explore the influence of sandstone architecture on waterflooding mechanisms using the architecture method,and taking as an example the M-I layer of the Kumkol oilfield in the South Turgay Basin,Kazakhstan,we portrayed the architecture features of different types of sandstones and quantitatively characterized heterogeneities in a single sand body in meandering river *** on the waterflooding characteristics of point bar sand and overbank sand according to waterflooded interpretation results in 367 wells and numerical simulation results of well groups,we finally analyzed the remaining oil potential of the meandering river sandstone and pointed out its development directions at the high water cut *** result shows that because lateral accretion shale beds are developed inside single sand bodies,the point bar sand is a semi-connected *** overbank sand is thin sandstone with poor connectivity,small area and fast lateral *** heterogeneity of the overbank sand is stronger than the point bar *** sandstone architectures control the waterflooding *** meandering river sandstones,the bottom of the point bar sand is strongly waterflooded,while the top of the point bar sand and most of the overbank sand are only weakly waterflooded or *** thickness percentage of unflooded zone and weakly waterflooded zone in point bar sand is 40％,and the remaining oil in its top part is the main direction for future development.

Journal of Earth Science 2014年第2期25卷 337-347页

作者： Huanqing Chen Yongle Hu Jiuqiang Jin Qiquan Ran Lin Yan research institute of petroleum exploration and Development PetroChina

Taking member one of Yingcheng Formation of Cretaceous in Xudong area, Xushen Gas Field of Songliao Basin for an example and aimed at the diachronous problem generally existed in vol- canic reservoir division, firstly advanced the method of two steps and two unites in the researches of volcanic reservoir finely division that guided by the method that sources controlled and founded the stratigraphic trellis. In this process, volcanic edifices and bodies were identified and traced. The results indicated that aimed strata in study areas could be carved up to six layers of YCII1, YCII2, YCII-II, YCIIlI, YCIII2 and YCIIII from the top to the bottom. Analyzing causes and firmly united of well data and seismic data could achieve fine stratigraphic division of volcanic reservoir. Surfaces of layers and volcanic bodies were basically unanimous in side direction. Stratum inclination gradually reduced with the distances increased from craters. The results of volcanic reservoir division had preferable con- sistency with lithologies and volcanic lithofacies and dynamic development data. The researches offered a useful method to stratigraphic division of volcanic reservoir and it had very important significance to effective development of volcanic reservoir in practice.
