Application of flow meters in onshore and offshore oil fields

flow meterThe accuracy of the selected instrument should be determined based on the level of measurement to avoid waste, including the detection components, primary instruments, and displays of the flow measurement systemRecording instrumentThe accuracy between them should be coordinated appropriately.

Application of flow meters in onshore oil fields: In oil field sites, for deep and ultra deep well drilling in various oil fields across the country, in order to solve the current problem of waste of high-density weighting materials, if 80% is recycled, at least nearly 90 million yuan in weighting material costs can be saved annually. Through theoretical research combined with field experiments, it is found that in order to achieve "real-time" recovery of weighting materials, it is necessary to consider the changes in viscosity and density properties of drilling fluidscentrifugeChanges in performance parameters, throughsensorAfter detection, the input control system provides the working speed and processing capacity of the centrifuge, which is controlled by a computer to meet the design requirements and establish the control system flow.

Application of flow meters in offshore oil fields: Offshore oil field platforms are divided into three main parts: process production systems, auxiliary process systems, and utility systems. Choose the appropriate oneflow meterApplied to different operating conditions of different systems.

(1) The selection of flow meters is a systematic engineering process, and there may be several options for instruments that can be used in a specific application site. It should be tailored according to the actual working situation and the flow meter with good performance should be selected.

(2) Selection should not be limited to standardized instrument selection, and thinking should be innovative, such as the current non standardized onesV-cone flow meterThere are many advantages that other flow meters do not have in many aspects, which are also worth discussing in the selection process.

(3) The installation position and direction selection of flow meters should be given sufficient attention. Specific instruments have specific installation requirements. Only with the joint cooperation of correct instrument selection, correct installation position, and sufficient length of front and rear straight pipe sections, can the measurement system ultimately achieve the required measurement accuracy.

Flow meters must meet the specified length of straight pipe sections and consider factors that affect instrument installation, such as temperature resistance, pressure resistance, vibration resistance, and safety protection; After using the instrument, the surrounding environmental conditions should be considered, including the convenience of daily maintenance and replacement of the instrument, the impact of environmental temperature, humidity, and electromagnetic interference on the instrument, and the safety performance of the environment.
