Sand control testing performance device

1、 Working principle

Sand control testing performance deviceSimulating oil and gas wells manuallyHigh pressure, high temperature, sand carrying fluid erosionReal working conditions allow sand containing fluids to continuously flow through test samples such as sand control screens and sand filtration media. Quantify the detection of samples through real-time monitoring of fluid flow rate, pressure difference before and after, sand leakage, and changes in sample wearSand blocking accuracy, flow capacity, anti clogging, anti erosionThe four core performance indicators are used to determine the quality and long-term reliability of sand control tools.

2、 Overall working logic of the device

1. Medium ratioAccording to the actual situation of the oilfield formation, mix water, oil, gas, and sand of different particle sizes to simulate real sand containing fluids.

2. Working condition loadingSimulate high temperature, high pressure, and production pressure difference environment underground through pressurization and heating systems.

3. Dynamic flushing filtrationHigh speed circulation of sand carrying fluid through sand control samples, replicating long-term sand production, erosion, and blockage processes underground.

4. Real time data collectionThe sensor records pressure difference, flow rate, sand leakage, and sample wear data throughout the entire process.

5. Performance evaluationBy analyzing data changes, determine whether the sample is reliable in sand blocking, has good flowability, is resistant to erosion, and is not easily clogged.

4、 Four core testing principles (corresponding to device functions)

1. Sand blocking performanceCounting the amount of fine sand passing through the sample, the less sand leakage, the higher the sand retention accuracy.

2. Circulation performanceMonitor the pressure difference before and after the sample, the smaller the pressure difference and the more stable the flow rate, the better the oil flow capacity.

3. Anti clogging performanceLong term cyclic test, observe the rate of pressure rise, the slower the pressure rise, the less likely it is to block.

4. Anti erosion performanceHigh speed sand carrying long-term erosion, detecting sample wear, deformation, and damage degree, and determining service life.
