Abstract

The invention discloses an oil reservoir injection-production scheme optimization design method. The method comprises the steps of: obtaining real-time oil reservoir data and categories of oil reservoir numerical distribution information included in the real-time oil reservoir data; correcting a display coefficient of the real-time oil reservoir data to meet a coefficient value condition; transforming the display coefficient of the real-time oil reservoir data to obtain real-time oil reservoir exploitation scheme data; inputting the real-time data of the oil reservoir to be predicted and the reference real-time data marked with the category of the oil reservoir numerical distribution information into a neural optimization network model based on an analysis training set constructed by combining the corrected real-time data of the oil reservoir and the real-time oil reservoir exploitation scheme data and the category of the included oil reservoir numerical distribution information; and determining optimized oil reservoir exploitation scheme data. In the prior art, an oil exploitation scheme may be inaccurate, so that the exploitation time can be prolonged. According to the scheme, the exploitation scheme is optimized according to the real-time oil reservoir data, so that the exploitation time can be effectively shortened, and the cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of oil reservoir data optimization, in particular to an optimal design method for an oil reservoir injection-production scheme. Background technique [0002] At present, the relatively mature mining technology for heavy oil and super heavy oil in my country is steam injection thermal recovery. The usual steam injection thermal recovery method is steam huff and puff. However, after a certain period of steam huff and puff for heavy oil to form thermal communication, only the crude oil in the oil layer near each well point can be recovered, leaving a large number of dead oil areas between the wells. , the general recovery rate is only 10% to 25%. [0003] In order to improve the overall effect of steam injection thermal recovery and the oil recovery rate, it is necessary to turn steam stimulation production into steam flooding production at an appropriate time. Steam flooding oil recovery is to continuously in...
