A Statistical Method of Linked Damage Points

Abstract

The invention provides a counting method of connected injury points. The method comprises the following steps: S1, collecting injury point records of N detection channels in a well wall detection process of a gas storage well, and storing the same in a database; S2. utilizing a temporary injury point allocation table tool and a set tool to allocate sets for all the injury point records in the database, carrying out set counting, and obtaining an injury point set chain table; and S3, building an injury point list and injury point counting tables according to the injury point set chain table andthe database. Through the injury point counting tables and the injury point list formed by the method, a grayscale image of wall thickness corrosion warning points can be seen, the consecutive numberof the injury points can also be known, and an oscillogram thereof can be seen at the same time. The method has the advantages of scientific design, safety and reliability.

Description

technical field [0001] The invention relates to the field of multi-data storage, in particular to a statistical method for connected damage points. Background technique [0002] Due to uneven wall thickness and uneven well wall stress, stress concentration is likely to occur, which is very dangerous to high-pressure pressure-bearing equipment, so it is necessary to detect the change of well wall thickness. So far, in the relevant literature, only a simple conclusion on the minimum thickness value of the borehole wall thickness, or the statistical data of the wall thickness variation range, these data cannot reproduce the full picture of the borehole wall thickness change, and it is not clear whether the damage points are continuous. In fact, it is not easy to achieve this goal, because the amount of data is large, and the statistics of continuous damage points are cumbersome. [0003] In order to solve the above existing problems, people have been seeking an ideal technical...
