The corresponding reasonable production and well spacing density to the three kinds of reservoir were calculated by using the method of economic limit evaluation and numerical simulation.

本文主要利用经济极限评价方法和数值模拟的方法确定出三类储层的合理产量以及井网密度。

This paper considers every factor affecting the well spacing density, uses net present value to improve the method for calculating economy rational well spacing density of matured oilfield.

本文提出经济采收率的概念 ，并以油田投入与经济极限井网密度关系及谢尔卡乔夫公式为基础 ，根据经济学投入产出均衡原理 ，建立了具有实际应用价值的经济采收率模型。

However, the pixel density of the film can be straightforwardly reduced by fabricating smaller array spacing and a smaller antenna size, as well as using a more tightly focusing lens for recording.

但是，薄膜的像素密度会由于通造更小的阵列间距和更小的晶须尺寸以及使用更精密的聚焦透镜等直接降低。

This study was focused on promting quality of rice through different plants spacing and density for controlling different groups quality so as to study the influence of quality of Zhengdao 18.

本试验是以提高稻米品质为宗旨，通过不同的栽插行距和不同的栽插株数，调控不同的群体，研究不同群体质量对郑稻18品质的影响。

The rational well spacing under certain perforating level and the rational open thickness under certain well density can be determined by this equation.

用此关系式可确定该类油藏给定打开程度下的合理井距及给定井网密度下油井的合理打开厚度。
