[0004] The development effect of the oil field in the development process is the joint influence of the congenital uncontrollable indicators and the acquired controllable indicators, and is the result of the mutual influence and interaction between various element indicators. However, this method is relatively limited in the selection of indicators, and can only select However, the indicators in the standard do not take into account the innate geological quality factors of oilfields and development investment and other factors; moreover, this method does not consider the complex relationship between oilfield development indicators, and only analyzes and evaluates each indicator separately

Embodiment 1
[0099] Embodiment 1 of the present invention provides a method for evaluating evaluation objects, the process of which is as follows figure 1 shown, including the following steps:
[0100] Step S11: Obtain valid data for evaluating the evaluation object.
[0101] In one embodiment, after receiving the data of at least one indicator of at least one evaluation object, the validity of the data is identified to obtain valid data.
[0102] It can be, for each numerical value, carry out the validity identification of index validity and value validity at the same time; or, after receiving the data used to evaluate the evaluation object, first screen the effective index, and then screen each index for each index. A valid numeric value for the evaluation object.
[0103] The identification of the validity of indicators and values may specifically be: screening the effective indicators of each evaluation object according to the pre-stored indicator list, and screening the effective ...
Embodiment 2
[0143] Embodiment 2 of the present invention provides a specific application of the above-mentioned method for evaluating the price object, which is used to evaluate the oilfield development level. The oilfield development level evaluation method provided in this embodiment is as follows: image 3 As shown, the specific steps are as follows:
[0144] Step S31: Obtain valid data for evaluating the oilfield to be evaluated.
[0145] The obtained effective data includes at least two values of various indicators of the oilfield to be evaluated.
[0146] The indicators include at least one indicator of the pressure indicator, the state indicator and the response indicator in the pressure-state-response PSR model.
[0147] In one embodiment, the pressure index at least includes: reservoir permeability, formation crude oilviscosity, permeability variation coefficient and reserve abundance; the state index at least includes: recovery rate, water flooding reserve control degree, F...

Abstract
The invention discloses a method and a device for evaluating an evaluation object. The method comprises the steps of obtaining effective data used for evaluating evaluation objects, wherein the effective data comprises numerical values of various indexes of at least two evaluation objects; for each index, calculating the weight of the index according to the numerical value of the index of each evaluation object in the effective data; for each evaluation object, calculating a comprehensive evaluation index of the evaluation object according to the weight of each index of the evaluation object and the numerical value of each index; and determining the category or grade of each evaluation object according to the comprehensive evaluation index of each evaluation object. According to the scheme, multiple indexes can be flexibly selected for evaluation for multiple evaluation objects, analysis and evaluation can be performed by integrating the mutual relation among the indexes, and the evaluation result has higher rationality, accuracy and practicability.
Description
technical field [0001] The invention relates to the technical field of data analysis and evaluation, in particular to a method and device for evaluating evaluation objects. Background technique [0002] The natural energy of my country's oilfields is generally insufficient, and most of them are in the middle and late stages of development. The development method of artificial water injection is mainly adopted, and the reserves of water flooding oilfields account for more than 85% of the total reserves. Through the evaluation of oilfield development level, we can objectively evaluate the current state of oilfield development, find out the main factors affecting the development effect, and formulate corresponding measures to improve and enhance the oilfield development effect, which is of great significance to the efficient development of oilfields. [0003] At present, the evaluation of oilfield development level is mainly carried out in accordance with the Petroleum and Natu...
