Evaluation of the Influence of Pre-Crosslinked Polymer Particle Blocking Agent and its Surface Adhesion on the Plugging Effect
Pre-crosslinked polymer particle blocking agent is a new efficient water blocking agent in the oil field.The adhesion behavior of the blocking agent particles will affect its migration-blocking ability in the formation.In this paper,a macroscopic detection method of the adhesion of precrosslinking blocking agent is used,which explored the influencing factors and degree of the adhesion of the blocking agent,and studied the relationship between the adhesion on the sealing ability and the migration ability.The results provide a reference for the systematic evaluation of the adhesion performance of pre-crosslinked particle plugging agent in oil field.In the mine test,the adhesion agent can be reasonably adjusted to adapt to different effluent layers according to the experimental research results Plug-off,improve oil recovery.
