A Study On Motion Control Of Virtual Human In Virtual Training Simulation System

Due to the difference of physical properties of oil reservoir, the physical properties of fluid and the development state of fracture in different tectonic positions, the development effect exists great deviation in Chaoyanggou oilfield. In order to achieve cost-effective development in different blocks, the work of block sort management, classification study and administer have to be done. According to the geological characteristics and dynamic development realities of Chaoyanggou oilfield, this paper recognizes sand body form and scale statistically, studys the distinguishing feature of permeability distribution inside the sand body. Based on the reservoir geology classification, the key elements of level of classification, level of development and economic effect, separate the developed blocks into three synthetical categories using the block multi-level and multi-element comprehensive classification methods.Apply non-Darcy flow theory of low permeable sublayer reservoir and modern reservoir engineering method, analyse the reservoir infiltrating fluid characteristics of different blocks in Chaoyanggou Oilfield and utilize drive efficiently theory of low permeable sublayer reservoir to define the main technical factors affected dvisable well spacing density in Chaoyanggou Oilfield including permeability, the control degree of water flooding, the development degree of water flooding, the oil production rate and final recovery efficiency. In the light of oilfield development regulation and control and refer to the actual situation of Chaoyanggou oilfield, apply 5 technical descriptions to evaluate the well spacing density of different blocks in Chaoyanggou Oilfield. On the base of relation between recovery ratio and well spacing density, the consideration of the future value of crude oil sales revenue in the term of development of the field, the future value of development period, the future valure of matintenances and managements, utilize the equilibrium relationship between input and output, gain the computational methods of advisable well spacing density and limit well spacing density of low permeable sublayer under multi-elements releated to oil/water displacement efficiency, final recovery efficiency and reservoir characteristics.According to the research outcome of reservoir structural configuration, the regular pattern of reservoir sand distribution, injection and production capacity, the connectivity level of sand body, reserves abundance, fracture direction and the dynamic analysis of development, deploy different well spacing density program, apply numerical simulation methods to calculate and analyse comparatively the development index of different programs, finally optimize programs of development index as advisabile well spacing density program. Under the situation that adopting the economic limit well spacing density as well spacing density, design five points well network method, rhombus opposite nine points well network method, opposite seven points well network and square opposite nine points well network for the banded sand body and flaky sand body using numerical simulation method to calculate and compare the degree of reserve recovery of different well network, and compare the two well spacing pattern of well array paralleling sand body bearing of trend and perpendicular sand body bearing of trend, it is found that when well array parallel sand body bearing of trend, the degree of reserve recovery is greater than that of well array perpendicular sand body bearing of trend.The research outcome of this paper can provide theoretical guidance to certain rational spacing between wells and liners, choose advisable water flooding regime , deploy infill well and well network optimization regulation. All of the results have important practical significance on maintenance of high and stable yield and advisible efficient development.
