Abstract: The research on the characteristics of oil migration mechansim and pathway of oil migrating from K2qn1 source rocks down-ward to F, Y oil layer in Sanzhao Depression shows that the source faults of F,Y oil layer should be the T2 faults. The upper part of those faults disappeared in K1qn1source rocks, and the main faults just cut through T2, along from T2 to T3, from T2 to T4 and from T2 to T5 and distributed in the whole depression. The migration distance of oil downward from K1qn1 source rocks in Sanzhao Depression is mainly influenced by the difference between ancient overpressure of K2qn1 source rock and flow resistance during the process of migration downward and also influenced by combination way of faulted sandstone and mudstone in F, Y oil layer. It makes the deviation of actual downward migration distance with the theoretical migration distance. The actual distance of oil downward from K2qn1 source rocks is 300 m, and the high-value area mainly distributed in oil fields. The control factors of source faults to oil accumulation and distribution are given. The development area of source faults controls the area of oil distribution. The development degree of source faults controls oil downward migration distance. The high fault blocks nearby source faults are favorable for oil accumulation in F, Y oil layer. The distance to source faults controls the productivity of oil wells.

Abstract: Applications of real sandstone micro-models to research micro-flow characteristics of Chang 6 reservoir in Jiyuan area of Ordos Basin, and analyzes the relationship between physical property, Pore throat and displacement efficiency by combining thin casting sections, scanning-electron micro-scopes and constant-rate mercury injection. Results show that there are finger-like, reticular and homogeneous flows in Chang 6reservoir research areas and the rock of the research area can be divided to remind intergranular pore dissolved pore as well as dissolve-remind intergranular pore. Different types of rock have different microflow characteristics in which displacement efficiency is different. The displacement efficiency of dissolve mind intergranular pore is high, and the dissolved pore is low. Heterogeneity is the main internal factors affecting displacement efficiency, and physical properties and pore throat impact on displacement efficiency weakness. Of the external factors, water injection pressure and injection water multiple have a large influence on displacement efficiency compared to multiple injections. Improvements to the water injection pressure will have a better effect on improving oil displacement efficiency.

Abstract: Chang 8 member of Yanchang Formation is the major reservoir in Jiyuan Oilfield. With the development of oil and gas exploration, the areal heterogeneity of the reservoir has become an obstacle for further exploration and development, so the fine sedimentary facies description is particularly significant. Based on the analysis of sediment provenance and facies indicator, it is considered that Chang 8 member of Yanchang Formation is controlled by the provenances from the northwest and northeast, experienced the transformation from delta plain to delta front, and deposited distributary channel sand body which is superimposed vertically and continuous laterally. The physical properties of Chang 81 layer under different subfacies and different sources are contrasted. The result shows that the reservoir property of delta plain in Chang 8layer is better than that of delta front, and the reservoir property controlled by the provenance from northwest is better than that controlled by the provenance from the northeast. The favorable reservoirs of Chang 8 member are predicted, and it is considered that the reservoir in the northwest of Jiyuan Oilfield has great hydrocarbon potential.

Abstract: The lithology profile of Baer Depression in Hailar Basin is complex, which not only exists in the volcanic lava and sedimentary rock, but also has the transition lithology of volcanic rock. Conventional logging curve of obvious characteristics, better reflect the ability of large sedimentary thickness of lithology, but for the deposition of thin thickness, complex composition of transition rocks, often need to on the basis of the lithologic variation for the judgment. Based on the analysis of the relationship between the main lithology and well logging response of the Baer depression in Hailar basin, this paper presents and establishes 4 kinds of logging response patterns of the lithologic profile, and gives the corresponding well examples. The application of the logging response model of continuous lithologic profile will greatly improve the identification accuracy of the thin and complex composition of the transitional lithology.

Abstract: The thickness, lateral connectivity and boundary position of the thin layer are increasingly becoming the focus of lithologic seismic exploration, but the recent progress on thin layer have less systematic summary. Therefore, four aspects of thin layer research relating to research subject, forward modeling method, time-frequency analysis method, thickness prediction method are summarized. The following conclusions show that spectrum variation regularity of reflected wave is the key to thin layer analysis. A quantitative relationship between the peak frequency or notches frequency and thin layer thickness has already established. Wave equation forward modeling can reflect the dynamic characteristics of seismic wave in the propagation process, so the simulated wave field information is more rich and real. Analytical tools of reflected wave field are from time domain, frequency domain analysis to the time-frequency analysis and temporal characteristics of the reflected wave spectrum are took more attention. Thus wave field characteristics of thin layer are gradually evolved from a simple qualitative analysis to quantitative prediction direction.

Low back pain affects a large proportion of athletes. The purpose of this study was to perform a comprehensive review of literature regarding prevalence of low back pain, treatment, and rehabilitation with a specific exercise programme. With the information gathered a rehabilitation programme will be proposed with emphasis on specific exercises and progressions that can be used to help guide rehabilitative clinicians in their treatment and rehabilitation of the athlete with low back pain. A search of electronic databases was performed including; Pub Med, Medline, and Google Scholar. Key Words used: Spondylolysis, Lumbar stabilization, core stabilization, low back pain, athletes, exercise, and any combination of these words. Based on the search of electronic databases their does appear to be some efficacy of exercise programme established in the athletes with low back pain. However, at this time does not appear to be superior to other exercise interventions. The most effective prevention strategy seems to be exercise, specifically trunk stretching and strengthening exercises. It is not the intent of this study to create an all-encompassing approach to treating every athlete, but to give some insight into the best strategies and progressions to receive the best outcomes possible. However, further high quality studies, isolating specific primary interventions need to be completed in an attempt to reduce the burden of low back pain in athletes.
