Abstract: In the process of oil and gas field development, as the production progresses, sand control screens tend to be blocked and damaged at the bottom of the well caused by sand production, which severely shortens the production life of the oil well. This paper introduces a set of equipment system that uses a test method to evaluate the sand control effect of screen sand control media based on a domestic offshore loose sandstone oil field, which can effectively evaluate the sand control of different sand control technologies and sand control screen sand control media in loose sandstone oil fields. The system design fully considers the degree of formation sand production, the size of the production pressure difference and the change of formation temperature. It is mainly composed of the main test device, sand adding control system, constant pressure and constant speed power system and temperature control adjustment system, which can meet the needs of oilfield development. Requirements for evaluation and optimization of completion sand control technology.
