Through studying it is shown that in chagan sag, the geothermal gradients in the center are higher than those around the sag margin and major factors influencing the characteristics of temperature field distribution are the property of geotectogenesis and the differences in tectonic portion, lithology and underground water behaviour ; there are three types of mudstone compaction, i. e. normal compaction, undercompacition and overcomepaction ; there are two pressure systems in sandstone reservoirs, i. e. normal pressure and negative pressure systems and the strata ' s being uplifted and denuded is the key factor leading to the formation of the negative pressure system in reservoir ; and the distinctive temperature - pressure field characteristics in the sag are possessed of important petroleum geological significance in hydrocarbon source maturity, hydrocarbon generation, widening on oil and gas exploration domain and selecting exploration targets, etc
研究表明，查干凹陷中心的地溫梯度高於凹陷邊緣，大地構造性質及所處構造部位、巖性與地下水活動的差異是影響凹陷地溫場分佈特徵的主要因素；泥巖壓實存在正常壓實、欠壓實和過壓實三種類型，砂巖儲層段壓力類型可分為正常和負壓兩個系統，地層抬升剝蝕是導致儲層負壓系統形成的主導因素；凹陷獨特的溫壓場特徵對烴源巖成熟、油氣生成、油氣勘探領域的擴大及勘探方向的選擇等具有重要的油氣地質意義。In the third chapter, the mathematical models of project system have been established, and simulation has been done on the simulink enviroment of matlab software kits. the simulation focus on the effects of main parameters on the dynamic characteristics of speed control system, and the main parameters include viscosity damp coefficient and friction torque of electrical motor shaft, internal leakage coefficient of pump / motor of hydraulic circuits, gas volume of pressure accumulator, viscosity damp coefficient of cylinder piston and different running building floors, etc. at last, theoretical research effects of the flow and pressure pulsation of pump / motor on car speed and oil volume leakage theory are discussed. the fourth chapter of this thesis concerns the research on the key items about hydraulic power control system according to the ens 1 - 2 and other hydraulic elevator standards
