In this paper, theoretical mathematical model of reservoir simulation using tracer is given and an ideal tracer reservoir model is established. Numerical simulation results show that the injected concentration of tracer has no effect on breakthrough time and peak time of the tracer, but breakthrough concentration and peak concentration increase along with the injected tracer concentration. The higher...
During the production of oilfield, it is necessary to understand the strata pressure in the recovery process, which is the so-called current formation pressure. However, how to choose the pressure monitoring well point correctly is one of the important tasks in the oilfield development. Usually the simplest method of understanding the strata pressure is actual measurement, but in order to get the...
According to the fact that starting up pressure gradient exists when fluids flow in low permeability reservoir, a concept called effective driving coefficient is introduced to this paper,the recovery ratio calculation formula of low permeability is proposed, and also the formula is revised by using the effective driving coefficient, on that basis, the authors establishes an economic evaluation model...
Fracturing of oil layer is one of the effective measures of improving inefficient well capacity, and it is applied by many oil fields at home and abroad. This paper analyzes quantitatively the main factors of influencing the fracturing effects, gives the relation between fracturing effects and the parameters, and divides the grade intervals of each influencing factor quantitatively, then establishes...
With the rapid development of computer, applied mathematics and reservoir engineering, which have provided a technology platform for the scientific management, digitalization and informationization of reservoir, the integration research of geological modeling and numerical simulation is more and more emphasized in oilfield.
