目前传感器运用在各大油田开采作业中，对于在油田开采传感器的应用，油田开采是指受单一局部构造单位所控制的同一面积内的油藏、气藏、油气藏的总和。如果在这个局部构造范围内只有油藏，称为油田；只有气藏，称为气田。但是油气聚集的场所一般不是油气生成的地方，油气藏是油气经过运移、聚集才形成的。油田开采是油气现在聚集的场所。石油和天然气之所以能够聚集起来，是由于这里受局部构造单位控制，形成了各种圈闭。
这类局部构造单位可以是穹隆、背斜、单斜、刺穿构造等等，在它们所控制的范围内往往伴生多种圈闭，从而形成多种油气藏。这些受同一局部构造单位控制的面积内油藏、气藏的总称，就是一个油田开采。
如果说油藏是勘探是寻找原料，油田开发和采油是提供原料那么集气站的功能是收集气井的天然气，对收集的天然气进行气液分离处理后，处理后分别对气液进行计量；分离出的天然气需进行压力控制，使之满足集气管线的输送压力要求。为此集气站的工艺流程通常为集气、分离、计量、清管等。
为了提高油田计量的准确性，气田集气站都采用气体流量传感器来计算油田计量，气体流量传感器主要由壳体、前导向架、叶轮、后导向架、压紧圈和带放大器的磁电感应转换器等组成,吸取国内外先进技术进行设计，综合气体动力学、流体力学、电磁学等理论而自行研制开发的新一代高精度、高可靠性的紧密气体流量传感器，具有出色的低压和高压计量性能，多种信号输出方式以及对流体扰动的低敏感性，广泛适用于天然气、煤制气、液化气、轻烃气等气体的计量。
气体流量传感器工作原理当被测流体流经传感器时，传感器内的叶轮借助于流体的动能而产生旋转，叶轮即周期性地改变磁电感应系统中的磁电阻，使通过线圈的磁通量周期性地发生变化而产生电脉冲信号，经放大器放大后传送至相应的流量积算仪表，进行流量或总量的测量。
因而对于在油田开采传感器的应用，目前用的比较多的是气体流量传感器。这一传感器采用微机电系统（MEMS）流量传感器芯片来制作，适用于各类清洁、干燥气体。传感器采用标贴式安装，使安装尺寸更加紧凑，可以很容易的实现在小空间内的多传感器集成。
At present, sensors are used in the production of various major oilfields. For the application of sensors in oilfield production, oilfield production refers to the sum of reservoirs, gas reservoirs and oil and gas reservoirs within the same area controlled by a single local structural unit. If there is only a reservoir in this local structure, it is called oil field; only gas reservoir is called gas field. But the place where oil and gas accumulate is generally not the place where oil and gas are generated. Oil and gas reservoirs are formed by migration and accumulation of oil and gas. Oil exploitation is the place where oil and gas are now gathered. The accumulation of oil and gas is due to the formation of various traps controlled by local tectonic units.
This kind of local structural unit can be dome, anticline, monocline, piercing structure, etc. It often accompanies many kinds of traps within the scope of their control, thus forming a variety of oil and gas reservoirs. These oil and gas reservoirs within the same area controlled by the same local structural unit are collectively referred to as an oilfield production.
If the reservoir is to search for raw materials and the oilfield development and production are to provide raw materials, the function of gas gathering station is to collect natural gas from gas wells, and measure gas and liquid separately after gas-liquid separation and treatment. Pressure requirements. For this purpose, the gathering process of gas gathering stations is usually gas gathering, separation, metering and pigging.
In order to improve the accuracy of oil field metering, gas flow sensors are used in gas field gathering stations to calculate oil field metering. Gas flow sensors are mainly composed of shell, front guide frame, impeller, rear guide frame, compression ring and magneto-inductance transducer with amplifier. The advanced technology at home and abroad is adopted to design and synthesize gas. A new generation of high precision and high reliability tight gas flow sensors developed by ourselves on the basis of theories of dynamics, hydrodynamics and electromagnetism have excellent low pressure and high pressure metering performance, various signal output modes and low sensitivity to fluid disturbance. They are widely used in natural gas, coal gas, liquefied petroleum gas and light. Measurement of hydrocarbon gas and other gases.
The working principle of gas flow sensor When the measured fluid flows through the sensor, the impeller in the sensor generates rotation by means of the kinetic energy of the fluid. The impeller periodically changes the magnetoresistance in the magnetic inductive reaction system, so that the magnetic flux through the coil changes periodically and generates electric pulse signal, which is amplified and transmitted by the amplifier. The meter is sent to the corresponding flow integrator to measure the flow or total amount.
Therefore, for the application of sensors in oil field, gas flow sensors are widely used. The sensor is fabricated with a micro-electro-mechanical system (MEMS) flow sensor chip. It is suitable for all kinds of clean and dry gases. The sensor is mounted in a label mode, which makes the mounting dimension more compact and makes it easy to realize multi-sensor integration in a small space.
