Taking for example the salt rhythms of the Qianjiang Formation in the Qianjiang Sag of the Jianghan Basin (which is a typical Paleogene saline lacustrine basin in eastern China), through a detailed study on cores, the authors have determined for the first time the Ⅳ-order salt rhythm based on Ⅰ-,Ⅱ-and Ⅲ-order salt rhythms which were determined previously and got to know that the sedimentary process following the sequence of desalinizing→salinizing and crystallization of salt minerals from halite rock→(mud-bearing) glauberite rock→dolomite-bearing mudstone (mud-bearing doloston)→mudstone→doloston→glauberite rock→halite rock. The authors also analyzed the Ⅳ-order salt rhythm and the correspondence between its sedimentary records and the fluctuation of the palaeosalinity of waters and the short-scale (0.05~1.0 ka duration) change of dry-moist palaeoclimate.

Both of conventional continuous medium mechanics and noncontiguous medium mechanics, having strong pertinence, can abstract and simplify the rock model in research procedure, in which the rock body lying over the coal face can be considered as a static beam or board to leave out the push changes and the changes of property and load during the stability of overlying rock deformation has lost. Hence the derived profile equation is only the approximate expression of final subsidence of surface after the mining finished, and it is difficult to obtain the dynamic subsidence process of rock body.

传统的连续介质力学和非连续介质力学均具有针对性，在研究过程中将岩体模型抽象简化，将工作面上方的岩体看成是一静止的梁、板，省略了工作面的推进变化及覆岩在变形失稳时的性质和载荷的变化，得出的剖面方程仅是开采结束后地表的最终沉陷近似表达式，难以得到岩体的动态沉陷的过程。

Maturity of Lower Cretaceous source rock, researched by the authors, is closely relative to the deposition thickness of the Tertiary and the Quaternary. It shows that source rock at the depth of 4,000-4,400m is low mature, and 4,400-5,200m is in the peak of oil generating. Correspondingly, the source rock of the Zhonggou Formation is immature; the Upper Xiagou Formation is low mature; and the Lower Xiagou Formation and the Upper Chijinpu Formation are in the peak of oil-generating; and the Lower Chijinpu Formation is at the stage of generation of condensate-wet gas with high maturity. There is no source rock reaching the overmature stage of dry gas at present.

可溶有机质转化率、镜质体反射率、热解、生物标志物特征等参数表明：青南凹陷中部的下白垩统烃源岩生油门限深度为4000m（相应的镜质体反射率为0.65％），埋深4000～4400m为低成熟阶段，埋深4400～5200m为成熟生油高峰阶段，因此中沟组烃源岩未成熟，下沟组上部烃源岩低成熟，下沟组下部和赤金堡组上部烃源岩处于成熟生油高峰阶段，赤金堡组下部烃源岩处于高成熟的凝析油—湿气阶段，目前尚无烃源岩达过成熟干气阶段。

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.
