Comprehensive tripping monitoring operating system

Abstract

The invention relates to a comprehensive tripping monitoring operating system comprising a touch screen industrial computer and a PLC (Programmable Logic Controller) as a control system and a computing processing system. An acquisition system is formed by various sensors, and an executive operating system is formed by various controllers. The comprehensive tripping monitoring operating system is characterized in that an integrated intelligent program design is adopted and combined with qualitative analysis and quantitative analysis to integrally and comprehensively solve the problems of well kick and well leakage monitoring, single upright post timing counting, intelligent grouting and prevention of a runner wagon from knocking an upper overhead travelling crane and smashing a lower platform in the tripping process.

Description

Technical field [0001] The invention belongs to the technical field of petroleum drilling engineering, and relates to a comprehensive monitoring operating system capable of monitoring well kick and lost circulation, timing and counting of a single column, intelligent grouting and anti-collision crown block during the tripping process. The degree of early warning and alarm can be monitored step by step, and the leakage speed and leakage volume can be quickly monitored when lost circulation occurs. Background technique [0002] First of all, in the process of drilling and tripping in oil exploration and development, the current monitoring of well kick and lost circulation is to measure the liquid level of drilling fluid (commonly known as mud) at manual intervals, and the other is to rely on liquid level monitors (such as float type). Or ultrasonic liquid level monitor) to monitor the change of mud liquid level. The shortcomings of the above methods are: one is not scientific...

AI Technical Summary

Problems solved by technology

Although this method solves the problem of wasting energy by "big horse-drawn carts", it cannot solve the contradiction between anti-waterfall slurry and well leakage warning, that is, three columns are used to grout once for anti-waterfall slurry, and this cannot be done in time. Lost circulation found

If it is necessary to grout each column in order to detect well leakage in time, this will not solve the problem of anti-waterfall slurry

[0004] Third, in the process of drilling and tripping, the current practice is to manually record the timing and counting of a single column, which is prone to misrecording and omission

The reason why the prior art has problems of one kind or another is that the various tasks in the tripping process are not operated as an organic unity, and each work link can only operate independently without systematic integration, which will inevitably lead to a leak and a hidden danger. huge security risk
