The Cretaceous in southern china is mainly a set of red and mauve clastic rock,with evaporation layers. For lack of source rock,it has been paid little attention to in the exploration process. With the development of research on hydrocarbon exploration,the masses of Cretaceous reservoirs and shows have been found in recent years. This means that the Cretaceous has great exploration potential. According to the research,authors find that the high-quality reservoir and efficient cap rocks develop in the Cretaceous. At the same time,the Cretaceous and underlying Paleozoic-Early Mesozoic marine strata and overlying Cenozoic nonmarine strata constitute a superimposed basin. Moreover,high-quality source rocks developed in the above-mentioned two sets of strata. In the south,especially in the middle and lower Yangtze region since the Himalayan strong rift was associated with a large number of faults,These faults connect the Cretaceous reservoir and its overlying and underlying source rocks,forming the fault-based and unconformity-based discontinuous source-reservoir-cap accumulation assemblages. Because the Cretaceous has the abundant oil and gas from Paleogene source rocks or Mesozoic–Paleozoic source rocks with secondary hydrocarbon generation ability,three types of reservoirs develop in the Cretaceous:"new-generating and old-reservoiring" reservoirs,"old-generating andnew-reservoiring" reservoirs,and few "self-generating andself-reservoiring" reservoirs. The hydrocarbon enrichment depends on two key factors. Firstly,Cretaceous reservoirs are near to the source kitchens,so its oil and gas source is ample. Secondly,the fault system is well developed,which provides the necessary conducting systems for hydrocarbon accumulation.

THE FLOW PATTERNS OF BUBBLE PLUME IN AN MBBR

Journal of Hydrodynamics 2011年第4期23卷 510-515页

作者： LI Shi-rong CHENG Wen WANG Meng CHEN Chen Key Laboratory of Northwest Water Resources and Environmental Ecology of Ministry of Education Xi＇an University of Technology Xi＇an 710048 China oil production plant of No. 4 Changqing oilfield company China National Petroleum Corporation Jing Bian 718500 China

The flow patterns of the gas-liquid two-phase flow in a Moving-Bed Biofilm Reactor （MBBR） have a critical effect upon the mass transfer by the convection. Bubble plumes promote unsteadily fluctuating two-phase flows during the aeration. This article studies the unsteady structure of bubble plumes through experiments. The time-serial bubble plume images in various cases of the tank are analyzed. The Recursive Cross Correlation-Particle Image Velocimetry （RCC-PIV） is used to calculate the velocities in those cases, and then the time-serial vortex, the total turbulence intensity, the time-serial streamline are obtained. It is shown that the aspect ratio and the void fraction are the dominant factors influencing the unsteady structure of bubble plumes. When the aspect ratio is unity and the void fraction is high, the bubble plumes see a symmetrical vortex structure with a long residence time, which is beneficial for optimizing the aeration system and enhancing the applied range of bubble plumes.

Quantitative description of the high-capacity channels in unconsolidated sandstone reservoirs, into which water was injected to improve oil recovery, is a hot topic in the field of reservoir development. This paper presents a novel approach to describing quantitatively the characteristics of connected macropores in unconsolidated sandstone reservoirs using in situ production data. Based on physical simulation for formation mechanisms of high capacity channels and interwell tracer test data, a mathematical model was established to describe high-capacity channels by grey correlation theory, flow mechanism of fluid in porous media and reservoir engineering, and a program was developed to describe quantitatively the channel characteristics. The predicted results were consistent with field monitoring data （80%）, so this model could be economically and effectively used to identify high-capacity channels.

This paper presents a new aquathermolysis study of conventional heavy oil in superheated steam. A new high temperature autoclave was designed, where volume and pressure could be adjusted. Aquathermolysis was studied on two different conventional heavy oil samples under different reaction times and temperatures. Experimental results show that aquathermolysis does take place for conventional heavy oil. As reaction time increases, the oil viscosity reduces. However, the reaction will reach equilibrium after a certain period of time and won＇t be sensitive to any further reaction time any more. Analysis shows that, while resin and asphaltenes decrease, saturated hydrocarbons and the H/C ratio increase after reaction. The main mechanism of aquathermolysis includes hydrogenization, desulfuration reaction of resin and asphaltenes, etc.

Pyrolysis gases collected in the experiment prove that the dissociation of week bonds of heavy components present in oil occurs in the presence of high temperature water vapor. Field testing results show that downhole catalytic aquathermolysis enhances oil and water recovery,raises oil/steam ratio and extends production time during steam stimulation,which proves that it is a effective technology for recovering heavy oil under steam injection circumstances.

Control of neotectonic movement on hydrocarbon accumulation in the Kuqa Foreland Basin,west china

Petroleum Science 2010年第1期7卷 49-58页

作者： Jiang Zhenxue Li Lianxia Song Yan Tian Fenghua Zhao Mengjun Wang Haijiang Zhao Zhenxing State Key Laboratory of Petroleum Resources and Prospecting China University of Petroleum Beijing 102249 China Basin and Reservoir Research Center China University of Petroleum Beijing 102249 China Exploration and Development Research Institute PetroChina Beijing 100083 China Department of Exploration ＆ Development PetroChina CBM Limited Company Beijing 100013 China Exploration Department Tarim Oilfield Company PetroChina Kuerle Xinjiang 841000 China No.8 oil production plant Changqing Oilfield Company PetroChina Xi＇an Shaanxi 710018 China

Neotectonic movement refers to the tectonic movement that has happened since the Cenozoic, which is the latest movement. It has the most important influence on the basins in west china, especially on the hydrocarbon accumulation in the western foreland basins. We determined the time of neotectonic movement in the Kuqa Foreland Basin, which began from the Neogene, and analyzed the patterns of movement, which were continuous and fast subsidence in the vertical direction and intense lateral compression. The structure styles are that the faulting is weakened and the folding is strengthened gradually from north to south. We studied the control of neotectonic movement on the hydrocarbon accumulation process and model in the Kuqa Foreland Basin with basin simulation technique. The largest subsidence rate of the Kuqa Foreland Basin reached 1,200 m/Ma during the neotectonic movement, leading to rapid maturing of source rock within 5 Ma and a large quantity of hydrocarbon being generated and expelled. The thick neotectonic strata can form high quality reservoirs with the proved gas and oil reserves accounting for 5% and 27% of the total reserves, respectively. 86% of the structural traps were formed in the neotectonic movement period. The faults formed during the neotectonic movement serve as important migration pathways and they exist in the region where the hydrocarbon reservoirs are distributed. Abnormally high pressure caused by the intense lateral compression, thick neotectonic strata deposition and rapid hydrocarbon generation provide driving force for hydrocarbon migration. The accumulation elements match each other well over a short period, leading to many large gas fields formed later in the Kuqa Foreland Basin.
