Problems solved by technology

However, due to the late start of research on gas hydrate, there is no large-scale industrial exploitation data for reference, so the economic evaluation method of gas hydrate is still in the exploratory stage

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] The present invention is based on the most commonly used net present value method in the evaluation of oil and gas resources, combined with the technical characteristics of natural gas hydrate exploitation, concretely quantifies each economic factor, obtains the expression of net present value of natural gas hydrate exploitation project, and then according to For the definition of the minimum economic reserves, the reserves of natural gas hydrates corresponding to the net present value of zero are used to obtain the expression of the minimum economic reserves of natural gas hydrates. If the gas hydrate reserves to be exploited are less than the minimum economic reserves of gas hydrates, the project is not feasible and should be eliminated; otherwise, the project may be feasible; of course, in order to further ensure the feasibil...

Abstract

The invention relates to a measurement and calculation method of minimum economic reserves of natural gas hydrates, which is based on the net present value method most commonly used in the oil and gas resource estimation, combines with the technical characteristics of the exploitation of the natural gas hydrates and specifically quantifies various economic factors to obtain an expression formula of the net present value of an exploitation project of the natural gas hydrates, and then the corresponding reserves of the natural gas hydrates when the net preset value is zero are taken according to the definition of the minimum economic reserves, thereby obtaining the expression formula of the minimum economic reserves of the natural gas hydrates; the use of the method can very conveniently calculate the minimum economic reserves of one exploration project of the natural gas hydrates, thereby judging whether the exploration project of the natural gas hydrates has economic feasibility or not. The method of the invention is simple and concise. The various economic parameters of the method can also be modified according to the actual exploration situations, so that the method can be applied in a broader range.

Description

【Technical field】 [0001] The invention relates to the technical field of natural gas exploration, in particular to a method for calculating the minimum economic reserves of natural gas hydrate, which is used to judge whether the natural gas hydrate project is economically recoverable. 【Background technique】 [0002] Due to the shortage of coal and petroleum resources and the enhancement of people's awareness of environmental protection, the development and utilization of natural gas hydrate with huge reserves has attracted more and more attention as a clean energy. In the current field of gas hydrate research, the main work focuses on the physical properties of gas hydrate and the research on exploration technology, but there is little research on the method of minimum economic reserves of gas hydrate. [0003] The methane contained in natural gas hydrate can realize its economic value only when it is exploited. Like conventional oil and gas fields, the exploration and devel...
