The expandable sieve pipe performance detection experiment apparatus comprises a simulated stratum and wellbore system, a fluid circulation system, a pressure measurement system, a stress measurement system, a temperature control system and a data acquisition and processing system, wherein the simulated stratum and wellbore system comprises a constant temperature box, a kettle body arranged inside the constant temperature box, a flush pipe, an oil pipe, an expandable sieve pipe and a simulated well wall, the flush pipe, the oil pipe, the expandable sieve pipe and the simulated well wall are arranged inside the kettle body, the bottom portion of the kettle body is provided with an outlet, the side wall of the kettle body is provided with a fluid injection port and a pressure measurement hole, the fluid circulation system comprises a pre-heating device and a plunger pump, the pre-heating device pre-heats a fluid, the plunger pump injects the pre-heated fluid into the kettle body through the fluid injection port on the kettle body, and the pressure measurement system is connected to the pressure measurement hole and the outlet on the kettle body, and monitors the injection pressure, the outer wall pressure of the expandable sieve pipe and the outlet pressure.

Description

technical field [0001] The invention belongs to the field of sand control well completion for oil, gas and water wells, and in particular relates to an expandable screen pipe performance detection experimental device and evaluation method. Background technique [0002] The sand production of oil and gas wells seriously affects the normal production of oil, gas and water wells in sandstone reservoirs. Mechanical sand control completion technology is one of the main methods to solve the sand production problem. Mechanical sand control completion mainly includes independent screen and gravel packing completion methods, and there are many types Wire-wound screens, slotted liners and sand filter pipes are widely used as sand control screens in oil, gas and water wells as the main tools in the above-mentioned well completion methods, and there has been a lack of uniform standards for performance testing and evaluation. [0003] Compared with conventional hanging sand filter tube s...

AI Technical Summary

Problems solved by technology

Expandable sand control screens are mainly used in sand control and completion of open-hole horizontal wells. The independent screen completion technology is used to achieve the effect of gravel packing completion annulus filling and sand control. It has the advantages of simple process, short completion period and high sand control accuracy. , long validity period, the current sand control screen evaluation experimental devices and methods are not suitable for this type of screen, and cannot evaluate the overall performance of the expandable screen well
