A display method and processing terminal for the existence state of hydrate and free gas

Abstract

The invention relates to a displaying method of existence states of a hydrate and free gas as well as a processing terminal. The method comprises the following steps in sequence: 1, in logging evaluation software, the scales of a neutron curve, a density curve and an interval transit time curve are set, the three curves of the neutron curve, the density curve and the interval transit time curve are generally referred to as three-hole-degree curves, and the three-hole-degree curves are enabled to be intersected; and 2, a corresponding mark is marked on the three-hole-degree curve intersection area, the existence states of the hydrate and the free gas are judged according to the corresponding mark, and the mark is displayed through display equipment. According to the method, the three-hole-degree curves are intersected, the existence states of the hydrate and the free gas can be intuitively judged, not only operation is convenient, the efficiency is also extremely high.

Description

technical field [0001] The invention relates to the technical field of geophysical prospecting well data evaluation, in particular to a display method and a processing terminal for the existing state of hydrate and free gas. Background technique [0002] At present, in the process of gas hydrate (referred to as hydrate for short, the same below) accumulation research process, it is identified whether the existence state of hydrate is water-saturated or gas-saturated, or the coexistence state of hydrate and free gas. It is of great significance for the understanding of gas accumulation and the calculation of hydrate saturation. However, at present, there is only an inferred understanding of the existence of hydrates, especially the coexistence of hydrates and free gas, without actual evidence, and there is no effective method to show whether the current hydrates exist. The state of coexistence of hydrate and free gas can only be inferred through theoretical analysis at prese...

Problems solved by technology

[0003] In view of the deficiencies in the prior art, one of the purposes of the present invention is to provide a method for displaying the existence state of hydrates and free gases, which can solve the problem that the existence state of hydrates cannot be judged intuitively;

[0004] The second object of the present invention is to provide a processing terminal, which can solve the problem that the existence state of hydrate cannot be judged intuitively
