In order to research the application extension of the viewpoint of the four key factors controlling formation process of lithologic traps, the paper was dissected lithologic reservoir dynamically, mainly analyzing the paleo-fluid dynamics, paleo-hydrocarbon migration pathway, paleo-critical physical properties of reservoirs and paleo-sealing conditions of the traps in formation of hydrocarbon accumulation period. The results show that they recover the limited and most important factors for formation of lithologic traps and come back the formation process of lithologic traps availably, and it also can used to be evaluated low exploration basin dynamically, compositely analyzed key factors controlling formation process of lithologic traps and selected advantaged target area. The application of this methodology indicates that it could be widely used in the dynamic formation of lithologic traps and dynamical evaluation of low exploration basin in Hongliuquan area, Qaidam basin.

The existence of abundant hydrocarbon has been discovered in the Yakela Fault-convex, Tarim Basin, after reconstructing and superimposing for several periods. Through interpretation of 3D seismic data up to date, combined with the circumferential field geology, after comprehensively analyzing the characteristics of development on hydrocarbon migration passages and its relationship with hydrocarbon accumulation, this paper holds that it is divided into fault type, unconformity type and carrier bed type in the Yakela fault-convex. The unconformities and the carrier beds are the main lateral migration passage of gas and oil for long distance. The faults are the main vertical migration pathway of hydrocarbon, and the hydrocarbon can arrive at any strata with fault. It is significant to know the hydrocarbon migration pathways in the study area for exploration in future.

Based on the sequence stratigraphy principle, reservoir forming elements has been detailed analysis in Cretaceous system of Hailaer basin, by using core, logging and 3-D seismic data. The study shows that the thick mudstone layer in the transgressive systems tract of the super-sequence is good regional source rock .and regional caprock, meanwhile the sandbody developed in transgressive systems tract and highstand systems of the super-sequence become the regional reservoir of depression. The main hydrocarbon migration pathway is uncomformable surface, fault, frame-sandstone, or that the hydrocarbon born in source rock went into the sandstone of sublacustrine fan directly, and then, lithologic reservoirs was formed.

Through comprehensive study on the combination of each accumulation of Putaohua Reservoir in Xingnan area of Daqing Placanticline, analyzing the controlling factors of hydrocarbon accumulation, accumulation rule and the corresponding exploration ideas, Enriching and developing the study of non-structural reservoir in slopes and depressions of Daqing Placanticline. The study shows that faults are well-developed, especially oil source faults which were active during the crucial moment of hydrocarbon accumulation, as for connecting source rock and reservoir and poor sealing capacity, they are the main passage for hydrocarbon migration. The relations between oil source faults and reservoir greatly restrict the distribution and scale of reservoirs. Accurate evaluation of the relationship between faults and reservoirs has an important significance which can give a guide to the surrounding exploration of Daqing oilfield and improve the success rate of exploration.

Putaohua reservoir in south of Daqing Placanticline is rich in oil and gas resources. However, the distribution of oil and gas is so complex and the hydrocarbon accumulation process is still unclear by now. Due to low proven reserves, it is not effective to explore the reserves. By use of the logging interpretation and results of production test and together with analysis of the oil and gas distribution and hydrocarbon accumulation process of Putaohua reservoir in south of Daqing Placanticline, the controlling factors of hydrocarbon accumulation in aspects of oil and gas migration pathway, developmental characteristics of sand, local structure etc are discussed in order to optimize potential blocks. The hydrocarbon of Putaohua reservoir in both flanks in south of Daqing Placanticline is from the local K1qn1 source rock. Hydrocarbon migration mainly depends on vertical movement and is supported by short-distance lateral migration; hydrocarbon accumulation is mainly affected by restrictions of oil source fault and high fault block, so that most of hydrocarbon accumulate in the distributary channel and distal bar of reverse faulting footwall, horst, reverse fault and other high fault blocks where are closely adjacent to the oil source faults.

Based on the analysis of the relationships between the conditions of structures, sedimentations, source rocks, cap rocks, faults, oil and gas migration passages and traps and hydrocarbon accumulation, the controlling factors of hydrocarbon accumulation and distribution was studied in Talaha-changjiaweizi area. It is held that the source rocks control the hydrocarbon vertical distribution, the drainage capabilities control the hydrocarbon plane distribution, fracture belts control the hydrocarbon accumulation of Talaha syncline, underwater distributary channel is a favorable accumulation environment and reservoir physical properties control the oil and water distributions. Therefore, it is concluded that source rocks, fracture belts, sedimentary microfacies and reservoir physical properties are the main controlling factors of hydrocarbon accumulation and distribution in Talaha-changjiaweizi area.

Metal cutting is a complex process in which several mechanisms are at work simultaneously. The mathematical modelling allows carrying out research into the optimization of machining conditions. This work examines the simulation of chip formation during the process of cutting. The studies demonstrated that the chip formation process, taking into account the plastic deformation and destruction of metal in the local zone, is most appropriately represented by a rheological model in the form of a series connection of elasticductile- plastic relaxing medium of Ishlinskiy (reflecting the process of primary deformation of metal from the cut off layer) and the medium of Voigt with two elastic-dissipative elements (representing the process of deformation and frictions from the convergent shaving). The attained complex rheological model served as the basis for constructing a representative dynamic model for the chip formation process. The key factors that govern the chip formation have been taken into account, such as tool vibration frequency and amplitude, depth of cut, feed rate.

ABSTRACT Karst-related geo-disasters often occur in karst regions during underground construction. In recent years, a number of shallow buried karst features have been discovered in eastern China. Survey boreholes show that karst caves exist at depths of 26–30 m and 33–36 m, which are typical of shallow buried karst. Using cross-hole seismic computed tomographic techniques, 36 geological anomalies consisting of 26 mud-filled caves, three empty caves, and seven fissure zones/loose lens bodies were detected. Most of the karst caves were oblate or oval. After determining the scale of and the connection between the caves, the study area was divided into two areas to provide advice on the treatment of caves during construction. An analysis of the development characteristics of the karst suggests that karst is controlled by several key factors, including topography, structural features, groundwater conditions, and human activities. Following an analysis of these factors and field studies of the process of formation of the shallow buried caves, solutions are proposed to prevent karst-related geo-hazards. The research results can be used in the design of foundations for buildings that are located in regions that include shallow buried karst in eastern China.
