Instrumentation is a key piece of equipment used in oilfield production. Its main function is to measure pressure, temperature, liquid level, flow rate, and other production parameters of various equipment and processes during oilfield extraction. Driven by modern information technology, traditional instruments are gradually being replaced by automated instruments.
Automated instrumentation represents a major development direction in instrumentation today. Compared to traditional instruments, automated instruments offer numerous advantages and significantly enhanced functionality. Furthermore, my country's instrument automation technology is maturing rapidly, with the emergence of highly advanced automated instruments such as intelligent and digital devices. Automated instruments possess powerful computing and memory capabilities, and can be programmed and edited, enabling them to process large amounts of complex information and greatly contributing to the development of my country's oilfield industry. In summary, automated instruments offer the following functions:
(1) Calculation function. The presence of microcomputers in automated instruments has greatly improved their calculation and data processing capabilities, enabling them to handle more complex and massive engineering data and significantly improving the accuracy of calculation results. This has played a significant role in the development of petroleum production.
In oil production measurement, problems such as linearization, self-checking and self-calibration, conversion between measured and engineering values, and anti-interference are frequently encountered. The microcomputer and corresponding microprocessor software in automated instruments can effectively solve these calculation problems, which not only reduces the burden on hardware equipment in oilfield production, but also enables automated instruments to perform tasks such as retrieval and optimization, demonstrating outstanding computational capabilities.
(2) Programming Function. With the rapid development of computer technology, computer technology has been widely used in many fields, especially in instrumentation. This has enabled automated instruments to be programmable. Computer software has been added to the instruments, which can replace hardware logic circuits, thereby improving many of the instrument's performance characteristics.
(3) Memory function. The circuits used in traditional instruments are a combination of logic circuits and timing circuits. Therefore, the memory function of the instruments is relatively backward and the memory level is low. It can only basically remember the equipment operation status at certain specific moments in the oilfield production process. However, as time gradually changes, the working status of the instruments will also change accordingly. The data and information previously recorded by the instruments will be replaced by new information, and the old data and information will be lost. This will have a great adverse impact on oilfield production and mining, resulting in the loss of relevant production and mining data.
By integrating microcomputers into automated instruments, the powerful storage capacity of microcomputers can be used to memorize information and data from all states of oilfield production and extraction. This data will not be lost due to new data overwriting it, and the information can be permanently stored. Furthermore, adjustments and improvements can be made to address situations where only one state could be memorized at a given time, enabling the memorization of multiple oilfield production and extraction data within the same time period.
