Research On Automatic Control And Alarm Of Well Control

In the field of petroleum engineering,well control can be understood as kick control.Once found kick during drilling and uncontrollable circumstances,will result in well blowout,most likely caused by oil and gas Wells scrap,fire,construction equipment damage and cause serious environmental pollution and so on a series of accidents,and belong to the catastrophic accident,accident harm degree is relatively large.Developing design,the case for the research and development design has certain necessity.This thesis realizes well control for the development of early warning system design work,and early warning is relatively accurate,have a certain practicality and applicability.First need to inspect around well control the demand of comprehensive and in-depth analysis,gradually carry out the research and development design,the system in terms of research and development design,divided into two main research and development design,hardware design and software design part respectively.The hardware design part mainly implements data acquisition system,data processing system,alarm system and other system development design work.In the aspect of data collection article mainly reference to ultrasonic liquid level sensor,flow sensor equipment implementation of imports and exports,in the aspect of data analysis,recording and processing mainly combined with GPRS transmission technology,alarm system to realize the sound and light alarm;About a system software part mainly achieved through data modeling well control the bop to the research and development of early warning system,realize the human-computer interaction interface,data real-time collection function,at the same time also realized the port Settings,parameter setting,etc.Through indoor test and field test can be concluded that,the system signal from the judgment of testing data and have a certain precision,at the same time implementation in reception ways in the receive mode,operation mode to touch mode,etc.,system shows a more just,the system warning is more accurate and easy to popularize.
