Those formed during the flare-up period, i.e., the Pana Formation, however, show significant geochemical variations from low-K tholeiitic through calc-alkaline to shoshonitic compositions coupled with increasing enrichment in LREEs. Therefore, the volcanic successions are divided into four suites, namely, calc-alkaline suite, low-K suite, high-REE suite and shoshonitic suite.

Results In 11 cases,5 cases were intracranial,and 6 cases intravertebral canal.MRI could effectively show similarly shuttle or long-round shape's abnormal signal imaging.The T1W imaging showed uniformity or asymmetric and low or equal signal.The borders were slighty low or equal signal intensity,some had spetum.The T2W imaging showed obviously high signal,and a few cases showed slightly high or equal signal,while the borders showed slightly low or equal signal imaging.The thin peripheral could be obviously enhanced,but without inner enhancement.

Geophysical characteristics of Ordovician carbonate rock were studied using drilling data. Impedance is affected mostly by material properties and reservoirs types, to a negligibly extent by lithology and flow. Compact layers and minor\|fracture reservoirs of Ordovician carbonate rock have characteristics of high density, high velocity and high impedance, and the prediction of minor fractures reservoir is difficult by the general seismic ways. Big fractures and fractured\|vuggy and vuggy and cavity reservoirs of Ordovician carbonate rock have characteristics of minor density and low velocity and low impedance in central Tarim basin, which obviously different from the surrounding rock and produce obvious characteristics in seismic data, so reservoirs can be predicted by applying general seismic data.
根据已钻井资料,对塔中地区上奥陶统良里塔格组岩石地球物理特征进行了研究,结果表明:物性、储层类型对波阻抗影响最大,岩性、流体对波阻抗影响较小;奥陶系碳酸盐岩致密层和小裂缝型储层具有密度大、速度高、波阻抗值大的特点,利用地震常规预测手段较难预测出小裂缝型储层,而塔中地区奥陶系碳酸盐岩大裂缝型、裂缝-孔洞型、孔洞型、洞穴型储层具有密度小、速度低、波阻抗值小的特点,与围岩具有较为明显的差异,在地震上可以产生明显的响应,可利用常规地震资料来预测这种类型储层。

The results are shown as below.1 Tectono-thermal evolution: The history of the Songliao basin is divides into four stages, high-temperature doming and extension, high-temperature rifting, low-temperature depression, and low-temperature shrinkage. Numerical simulation of mechanical process shows that the basin appeared in the early- to late- Jurassic as a result of rapid low-angle subduction of the Pacific plate towards the northwest, of movement of the Siberian block towards the southeast, of many other influences such as internal thermal stress in the mantle, gravitational force, stress of phase transition, etc. Both the Pacific plate and the Siberian block slowed down in the early Cretaceous, and almost stopped in the middle Cretaceous with the rapid decrease of abnormal heat in the mantle below.
盆地构造热演化力源机制数值模拟研究表明:早、中侏罗世至晚侏罗世晚期,盆地演化主要是太平洋块体向北西方向以低角度快速俯冲和西伯利亚块体向东南俯冲共同作用的结果,同时也与地幔内部热力、重力、相变力以及地球自转及公转速度变化效应和上覆块体绝对运动的作用有关;早白垩世早期至早白垩世中期,来自东部太平洋块体俯冲作用的减弱,而这一时期影响盆地演化的主要力源是地幔内部热力、重力、相变力以及地球自转及公转速度变化效应和来自西伯利亚块体俯冲作用;进入早白垩世晚期至晚白垩世早期,由于双重俯冲带中西侧俯冲作用带基本停止活动,而本区地幔热能的快速衰减则控制盆地的构造热演化;晚白垩世晚期以后,太平洋块体活动加强和地幔热运动是影响盆地演化的主要动力。

And it is concluded that the No.4-2coal seam is a mid-reserve and low-permeable seam, with surrounding rocks having low enclosed system and high permeability. And the coal seam's gas content is low, while its quantity in the roof-sandstone which is the main source of coalface's gas emission is high . The quantitative index used to analyze gas content and gas emission amount are pointed out systematically. And gray association analysis method is adopted to search the main factors affecting coal-bed content and gas emission amount.
