储层真厚度求取新方法

The New Calculation methods of True Reservoir Thickness

将数学方法与地质情况相结合,根据储层真厚度的定义、计算原理和公式,运用地球物理的视角和研究方法,运用储层顶面的和底面的深度、构造倾角、构造倾向以及储层的铅垂厚度,推导出精确计算储层真厚度的计算公式,创新地求取了储层的真厚度。该方法与从井出发的常规计算方法相比,最大的优势是无需假定储层的顶底面是平行的,充分利用储层底面的构造信息,更为准确地得到储层的真厚度,具有方法简单、准确、不易出错的特点。

According to the definition, the calculation principle and formula of the true reservoir thickness, the true thickness of reservoirs has been calculated with mathematics and geophysical methods based on the geological conditions. With the top and bottom depth of the reservoirs, dip angle and trending of structure, the formula for calculation of the true reservoir thickness has been derived. Comparing with the conventional method, it is not necessary to assume that top and bottom surface of the reservoirs are parallel, which is one of the biggest advantages in calculation of the true reservoir thickness. By making full use of the bottom structure information, the true thickness of the reservoir can be calculated more accurately. This method is simple and accurate, with no errors.
