The collapse and burst pressure of screen is an important parameter to evaluate the service performance of screen. In the process of using screen, there will be pressure from the internal or external. If the sand layer of screen cannot bear the pressure and breaks, the formation sand will enter the oil pipe through the broken part, that is to say, sand control failure is declared. At present, metal mesh screen and wire wrapped screen are mostly used in gravel pack sand control in oil and gas fields. In order to solve the problem of sand bridge and block in gravel packing of deep-water oil and gas fields and large displacement and long horizontal well section, a multichannel bypass screen is designed. In the development of multi-channel by-pass screen in deep water horizontal well, the metal mesh is used as the filter layer, so the collapse and burst pressure of the metal mesh screen has been tested for many times, and the screen with different sand layer structure and processing technology has been tested for many times. Finally, a set of metal mesh type screen structure andprocessing technology which meet the internal and external pressure strength requirements is obtained.
