Numerical simulation of oil migration and accumulation is to describe the history of oil migration and accumulation in basin evolution. It is of great value in evaluation of oil resources and determination of the location and amount of oil deposits. Based on such actual conditions as the effects of fluid mechanics in porous media and 3-dimensional geology characteristics,a kind of modified method of second order upwind finite difference fractional steps implicit interactive scheme was put forward. As for the actual problem of dongying hollow,Huimin hollow,Tanhai region and Yangxin hollow in shengli Petroleum oil field,a numerical simulation test was carried out,and the result is basically coincident with the actual conditions. For the model problem,optimal order estimates were derived. Thus the well-known problem on oil resources was solved.

The concept and division method for petroleum accumulation system,based on layer structure,are presented according to characteristics of layer structure and reservoirs. The petroleum accumulation system of Jiyang depression can be divided into four levels,namely petroleum accumulation system combination,petroleum accumulation system,oil-gas reservoir combination and reservoir. The petro-leum accumulation system combination includes three types of genetic pattern: other-source bur-ied-ridge accumulation system combination in pre-Paleogene,medium-deep layer self-source accu-mulation system combination in Paleogene,and shallow layer other-source accumulation system combination in Neogene. This paper also describes the reservoir types and their distribution charac-teristics of different petroleum accumulation system combinations and their interior units.

A mathematical model for phase equilibrium prediction of multi-component gas separation process inside a supersonic separator is established and an efficient numerical solution method is designed. The model and the numerical method are then used to predict the phase equilibrium characteristics and the separation performance of a field test natural gas supersonic purification separator. The predicted results are generally in good agreement with the field test measurements, which proves that the phase equilibrium model and the solution method are both reliable and accurate, and can be used for the prediction of the vapor and liquid phase equilibrium and the separation performance and the configuration optimization of supersonic separator.

Infrared thermo detector is a kind of non-contact instrument used to measure the surface temperature of objects. It incorporates high technologies of optics, infrared and electronics, and has been increasingly popularized in china. Firstly, the advantages and shortcomings of ST2. infrared thermo detector were analyzed. Then based on the requirement of detecting buried geological structures in underground coalmines and the features of ST2., two projects had been studied to modify ST2.: 1) Increasing the resolution of temperature measurements by means of improving the electrical circuit and carrying out field test; 2. Realizing flame protection of ST2. and passing the state-level test and appraisement. In addition, actual application experiments had been carried out for detecting underground buried geological structures (fault, fold, crushing zone, crack, porosity, gas and spontaneous combustion areas, etc.). Some good results have been achieved and valuable conclusions have been drawn.

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.

A segment of Mesozoic subduction-accretion zone was inferred across thenortheastern South china Sea at approximately NE450 orientation. Basic evidence includes thefollowing: A belt of peek gross horizontal Bouguer gravity gradient (PGHGBA) is comparable in sizeand intensity to that of the Manila subduction-accretion zone. A belt of high positive magneticanomalies appears to the north and sub-parallel to the PGHGBA, representing the volcanic arcassociated to the subduction zone. The PGHGBA crosses obliquely both Cenozoic structures and presentseafloor topography, indicating a pre-Cenozoic age. The segment is offset left-laterally byNW-running strike-slip faults, in concord with the Mesozoic stress field of South china. Inaddition, the existence of the subduction zone is supported by wide-angle seismic data obtained indifferent years by different institutions. At approximate localities, a north-dipping ramp of Mohosurface is indicated by records of ocean-bottom seismometers, and a strong reflector about 8 kmbeneath the Moho reflector is indicated by both OBS and long-cable seismic records. Theidentification of a segment of Mesozoic subduction zone in NE South china Sea fills nicely the gapof the Great Late Mesozoic Circum SE Asia Subduction-acrretion Zone, which extended from Sumatra,Java, SE Kalimantan to N Palawan, and from Taiwan, Ryukyu to SW Japan.
