Problems solved by technology
[0003] Existing methods are mainly based on single-well dynamic and static data, single-well logging data or mathematical methods to directly select the reservoir for refilling holes, but the research lacks in oil testing data, low-resistivity oil layer dynamic and static classification data, and adjacent well production in the same layer. Fusion analysis of data and other types of data does not make full use of the large amount of static and dynamic data accumulated in oilfield development, and the research cannot reflect the current level of understanding

According to the embodiments of the invention, a method and a device for determining the position of a perforation layer of an oil reservoir are disclosed wherein the method comprises the following steps: obtaining the well measuring data and well logging data of the current well; identifying a low resistance oil reservoir in the current well based on a predetermined low resistance reservoir database and the well measuring data and the well logging data; selecting the position of the to-be-stitched perforation layer for the low resistance oil reservoir in the current well; calculating the production potential at the position of the to-be-stitched perforation layer for the low resistance oil reservoir according to a preset rule; and based on the calculated production potential, determining the position of the perforation layer of the oil reservoir. With the method and the apparatus provided in the invention to determine the position of the perforation layer of the oil reservoir, higher reliability in doing so can be achieved.
Description
technical field [0001] The present application relates to the technical field of petroleum exploration and development, in particular to a method and device for determining the perforation layer of an oil layer. Background technique [0002] Compared with the adjacent water layers, the characteristics of electric survey curves of low-resistivity oil layers are less different and identification is more difficult. At present, the research is mainly focused on the cause and identification of low-resistivity oil layers, and further potential research after identification has just started. On the one hand, there are relatively many studies on conventional oil layers, which are mainly divided into three aspects: research by mathematical methods, comprehensive research on single well geology, and new technology research on single well logging. [0003] Existing methods are mainly based on single-well dynamic and static data, single-well logging data or mathematical methods to direc...
