Problems solved by technology

This method is mainly used for the evaluation of proven reserves. When the exploration and development entities are inconsistent, the exploration investment benefit can be quantitatively calculated in combination with the market value of reserves transactions. In the process of reserves transactions, this method can play a reference role in discovering market values; but When the subject of exploration and development is the same, this method cannot reflect the actual benefits of exploration investment

Embodiment 1

[0024] A method for evaluating the benefits of exploration investment in oil and gas field development and construction projects involved in this embodiment includes the following steps:

[0025] (1) Determine the development index system and investment in exploration and development of oil and gas field development and construction projects;

[0026] Specifically, the project development indicators include annual output and other indicators, which are determined according to the law of oil and gas field development; the exploration and development investment includes all investment in exploration and detailed exploration in the relevant area, development investment, working capital and interest during the construction period Calculated according to the actual occurrence of the production capacity construction stage, the specific performance is as follows:

[0027] Total project investment = construction investment + working capital + interest during the construction period; ...

Embodiment 2

[0066] In this embodiment, the exploration investment benefit evaluation method of the oil and gas field development and construction project in Embodiment 1 is used to evaluate the exploration investment benefit of an oil field development and construction project. The development indicators of this embodiment are as follows: figure 1 as shown, figure 1 The figure shows the change trend chart of the target annual oil (gas) production from 2015 to 2029 in the future. The unit cost change curve of this embodiment is as follows figure 2 As shown, the figure shows the change trend chart of unit operating cost, unit operating cost and unit total cost. The cumulative net cash flow curve before tax and after tax in this embodiment is as follows image 3 As shown in the figure, the cumulative net cash flow change trend diagram before tax and after tax is shown in the figure. Through the exploration investment benefit evaluation method of the present invention, the exploration ben...

Abstract

The invention relates to the technical field of petroleum resource exploration and development. The invention particularly relates to an exploration investment benefit evaluation method for an oil-gasfield development and construction project. The method comprises the following steps: determining an oil-gas field development and construction project development index system and exploration and development investment; determining various costs according to oil-gas field development cost factors; determining product sales income, sales tax and appendages, and establishing output data such as cash flows and post-tax profits of each year of the project by applying a discount cash flow method; and defining exploration output according to a principle that unit exploration investment and unit development investment are equal, and carrying out corresponding benefit evaluation. According to the method, the overall benefit of the project is determined through the discount cash flow method, theexploration benefit is decomposed according to the principle that the unit exploration investment and the unit development investment are equal, quantitative description of the exploration benefit inthe oil-gas field development and construction project is achieved, and the method plays an important role in controlling the exploration and development investment benefit of large oil and gas companies.

Description

technical field [0001] The invention relates to the technical field of exploration and development of petroleum resources, in particular to a method for evaluating the benefits of exploration investment in oil and gas field development and construction projects. Background technique [0002] There are many uncertain factors in the development and construction of oil and gas fields, so it is necessary to effectively evaluate oil and gas exploration and development enterprises. Related to it in the prior art is the value evaluation method of proven oil and gas reserves, that is, the method of quantifying the value of proven reserves when the proven reserves have not yet been developed. This method is based on constructing the cash flow of the reserve development process, and reversely determines the reserve value according to a certain internal rate of return standard. This method is mainly used for the evaluation of proven reserves. When the exploration and development entit...
