Design and application of submersible level transmitter for offshore platform


Abstract: with the development of China's modern economic development faster and faster, for the construction of natural gas resources and transmission application is more and more widely, offshore platform as gas resources exploration and the importance of factors, in the exploration of natural gas resources application, for in the application is more and more attention to the type liquid level transmitter and by means of the inputting type liquid level transmitter to the corresponding offshore platform technology application effect.In view of this, this paper conducts a special study on the design and application of the offshore platform submersible level transmitter, hoping to provide a reference for the design and application of the offshore platform submersible  level transmitter with the help of this study.

 

Design and application of submersible level transmitter for offshore platform

Preface

Natural gas exploration plays an important role in China's current economic development. In order to ensure the overall improvement of the construction and application capacity of natural gas resources in China, a comprehensive analysis should be made on the technical application during the construction and exploitation of natural gas resources.As an important form of natural gas exploitation, offshore platform is very strict in the application of technology in the construction of its platform.The application of the submersible level transmitter can improve the application effect of the offshore platform, which has important construction significance for improving the overall natural gas exploitation effect of the offshore platform.

1、Principle and characteristics of submersible level transmitter

As an important control factor in the design and application of the submersible liquid level transmitter, special analysis should be paid attention to its working principle and characteristic application to ensure that the corresponding design work can be well implemented and the corresponding work processing ability can be controlled and improved during the analysis process.According to this research in this paper, the corresponding transmitter design original selection for diffusion silicon and ceramic sensitive original as a special form of control application, at the same time, to transform, the signal transmission with the help of a 4-20 ma current signal output control the operation of the entire system, and its corresponding control liquid level transmitter input in a fixed depth control of the corresponding formula is:

P = P, g, H

On the type of P represents the corresponding pressure transmitter, P represents the density of the exploration area, and on behalf of the acceleration of gravity g, according to the principle of application of view, on the application of exploration technology, should be the corresponding acceleration of gravity change, security in the change factors of control, can send the corresponding pressure work to deal with.

2、Design and application of submersible level transmitter for offshore platform

2.1 determination of design parameters of the submersible level transmitter on the offshore platform

In the design process of offshore platform submersible level transmitter, the most important design factor is to make a special analysis of the design parameters, which is the important premise to ensure the application of offshore platform submersible level transmitter [1].In this paper, the post leg MEG level transmitter as an example of the application of its parameters to make a special design.The specific parameter design is shown in table 1:

Can be seen by the parameter design data in table 1, in the sea in the application of the type liquid level transmitter and the corresponding parameter in order to be able to design and the application of the offshore platform together, in technical applications, the sensor design part of the original by the stainless steel material processing the wear-resisting processing, but also for its protection grade level IP68 protection processing, through the implementation of the protection technology to the overall level push effect, at the same time, in order to ensure the inputting type liquid level transmitter push effect, in to push the implementation, to two line production to push the brake control system,Its corresponding braking control parameter is 4-20ma output with HART protocol. The application control of this parameter is of great significance for improving the overall application effect of the platform [2].

2.2 pump head design of MEG pump

In order to ensure in offshore platform application, to put it into type liquid level transmitter effect into play, in the design of invest type liquid level transmitter, MEG in the design of the pump to the specific analysis and design, through its analysis and design factors of implementation, to the whole gas extraction efficiency of offshore platform promotion lay the foundation.This article in view of the MEG pump pump head of the elements in the design of building install it in the bottom of the casing, and in the implementation of the installation technology, in order to be able to stable effects of liquid level transmitter, sensors installed in the pump head below 1 m, and has carried on the design for the cable fixed, step-down principle as the fixed installation of the cable technology, under the installation application of its technology, the implementation of the overall transport device installed, to facilitate the assembly work and implementation of the follow-up for the whole platform into type level conveyor installation.

 

2.3 application of submersible level transmitters on offshore platforms

Offshore platform design and development submersible type liquid level transmitter has importance for the whole Marine gas research significance, the current design of the device can not only be applied to the gas exploration technology applications, at the same time in the underground water level measurement and chemical and pharmaceutical industries in the development of the application of this technology is also more common.Through scientific assembly technology, the overall submersible level transmitter is installed in the construction area to ensure that the corresponding assembly work can be well implemented in the installation and application of its construction technology and that the overall assembly management effect can be brought into play in the application and implementation of the assembly technology.Usually, in the offshore natural gas exploitation, it is necessary to detect the natural gas reserves with this device, and in the application of detection technology, scientific detection management is carried out with the help of special detection technology to ensure the detection quality and the corresponding effect improvement.

3 conclusion

To sum up, in the development of modern petroleum exploration technology, more and more attention has been paid to the construction of offshore platforms. As an important construction factor in the construction, the design and application of the submersible level transmitter have important research significance for improving the application efficiency of offshore platforms.Through research and analysis of this article, the offshore investment type liquid level transmitter design parameters and the corresponding MEG pump pump head design are analyzed, and its application is the application of technology to implement demand has carried on the comprehensive analysis, but also for its installation technology in the real application has carried on the comprehensive analysis and elaboration, slip into type level to enhance general sea transportation is running effect, has important application significance.
