Abstract：Based on seismic data，logging and core samples，the sequence stratigraphy，sediment，sediment evolution，and their controls on reservoir distribution of lower Carboniferous are studied in southern Kazakhstan.The results show that lower Carboniferous can be divided into four three-order sequences.Every sequence is composed of trangressive system tract and highstand system tract，but lacks in the lowsand system tract.Maior sedimentary facies include evaporative carbonate platform，reef-shoal complex in the open platform，reef and shoal in the platform margin，intershoal lows，lagoon in the restricted platform，and drowned rimmed carbonate platform.In the highstand system tracts，open platform facies is dominant，while restricted platform facies is dominant in the trangressive tracts.Drowned rimmed platform develops in SQ3，and evaporative carbonate platform mainly develops in upper SQ4. Facies are wholly distributed in the form of close north-south each other.From south to north，there are tidal margin zone-restricted platform，sandy shoal in open platform，reef-shoal in the platform margin，and shallow sea-bathyal sea.The distribution of the reservoirs is controlled by the sedimentary facies and sequence.Favorable reservoirs mainly distribute in the high energy facies of the platform margin and higher quality reservoirs often distribute near the interfaces of three-order sequence and four-order sequence，and their porosity are greater than 10%.

Abstract：In accordance with insufficient cognition of Niutuozhen uplift rising time and inner structure，based on the previous research results，the method of geophysical method and equilibrium profile is applied to development process of Niutuozhen uplift.The results show that Niudong fault and adiusting fault form Y type，three reverse step faults under Niudong fault.The structure evolution can be divided into three stages：J-K was structure stage before the uplift was developed，J2end-J3was compressive and thrusting stage.K1k-E2d was development of Niutuozhen uplift，E2s3-E3d was Langgu-Niutuozhen fault-block rotation stage.N-Q was large depression stage.Mesozoic structure was controlled by regional extrusion and strike-slip motion.During the Cenozoic period，the evolution of the salient was controlled by extensional structure，strike-slip motion and basement subsidence.And it has connection with fault’s occurrence.By analyzing seismic profiles and structure evolution profile characteristics，it could be concluded that there were reverse faults in the uplift and Niutuozhen uplift was developed obviously in the E2s3.By analyzing the influence of source rock，reservoir，cap rock，migration passage and trap，it could be concluded that Ni-utuozhen uplift developed favorable conditions and buried hills reservoirs would probably be found.

Abstract：This work is aimed at the problems of high temperature and high salinity of Shengtuo oilfield and its low oil recovery by waterflood.We develop spontaneous emulsification flooding formula which adapt to reservoir condition of Shengtuo oilfield.A serious of emulsification tests and oil/water interfacial tension measurements were conducted to screen alkali，surfactant type and concentration of spontaneous emulsification flooding system.The results showed that the interfacial tension of oil/water could be low-ered to an ultralow level by synergistic effect combined alkaline and surfactant，leading to easy spontaneous emulsificationof oil under slightinterfacial disturbance.Its static adsorptionislittle，which on the oil sand is lower than the clean sand.The results of sandpack flood tests suggested that spontaneous emulsification system and residual oil could form emulsion under the shearing action of porous media in the homogenous sandpack，depended on emulsion droplets generated Jamin effect and shunt effect by plugging large pore throat，which improved the sweep efficiency and produced oil zone at the same time.The tertiary oil recovery increased by 25%by iniecting a 0.8 pore volume（PV）of alkali/surfactant slug.E-mulsion droplets formed in the heterogeneoussandpacksare insufficient to plug water channel effectively and entrained out of formation with the displacing fluid，result in lower oil displacement efficiency.

Abstract：In the process of CO2flooding，the gas slippage effect was affected by gas saturation.However the relationship between slippage effect and gas saturation is disputed.For researching the relationship，the slippage effect was tested in CO2flooding experiment which is under high gas saturation. However，the slippage effect under low gas saturation is hard to be tested.Therefore starch solution and plugging agent was used to build low gas saturation，and the slippage effect under low gas saturation was tested.Micro models were designed to find the reason caused the relationship between slippage effect and gas saturation.The result shows that slippage effect is little in the early stage of CO2floodng，because the gas is not a continuous phase；slippage effect increased with the increasing number of gas flow channel in the middle stage of CO2flooding；and the slippage effect decreased with the increasng of channel radius.Therefore，the slippage effect is under the influence of both the gas saturation and the gas saturation distribution.

Abstract：The fractal model for shale reservoir pores can indirectly reflect the characteristics that is difficult to observe directly.Using samples taken from Quanqian1 well from Sanquan profile in Nanchuan and Guanyinqiao profile in Qiiiang，the based structural features were studied by low-temperature nitrogen adsorption experiments and the FHH fractal model was established.The relationship between fractal dimension values and pore structure parameters，TOC content were discussed.The results shows that the shale pores were mainly distributed in micropore under 40 nm and have obvious fractal characteristics.The fractal dimension lies between 2.76～2.85 with correlation coefficient higher than 99%reflecting the complex pore structures and strong heterogeneity.Some samples shows dual fractal feature and the pores can be divided into seepage pore and absorption pore bounded by methane molecular free path.The fractal dimension D1for absorption pore（2.881～2.917）is higher than D2for seepage pore（2.791～2.823）.The relationship between pore volume，average pore radius and fractal dimension were negatively correlated and the relationship between specific surface area and fractal dimension were positively correlated which shows that the smaller the average pore size，pore volume is and the bigger the specific surface area is，the fractal dimension is more close to 3.There is a positive correlation between the fractal dimension values and TOC content which shows that the TOC content is an important influencing factors of fractal dimension values.The fractal dimension value can be used to evaluate the complexity and heterogeneity of reservoir pore quantitatively.It provides support for new reservoir evaluation methods and shale gas occurrence and migration mechanism in nano-pore research.
