Abstract: It is an innovative idea to realize the decentralized and independent control of oil reservoir exploitation and finally realize the intelligent control of oil field exploitation by using the micro hydraulic system to drive oil field cementing slip sleeve separately in sections. The existing micro hydraulic pump is difficult to meet the requirements due to the extremely narrow layout space. A single piston micro pump with valve distribution structure
