Film-forming resin anti-collapse agent

Wellbore instability is a complex longterm problem that affects the drilling costs of old oilfields and the progress of drilling in new areas. For the new area drilling, the most effective asphalt anti-collapse agent is currently banned by the geological department because of its high fluorescence level. Therefore, it is of great significance to research and develop new high-efficiency anti-collapse agents with no pollution and no fluorescence. Generally, saturated carbon chain polymers have no fluorescence, and polar groups such as branched light groups and sulfhydryl groups have affinity adsorption with clay, which play a role in bonding reinforcement in the interstices of clay particles. DY-067 is a preferred film-forming resin, a non-ionic saturated carbon chain polymer. When an aqueous solution or drilling fluid prepared by it meets a porous medium (such as rock), it can penetrate a small amount of water into the medium,thus forming a dense and strong film on the surface of the medium to prevent water from continuing to enter. so DY-067 is a non-fluorescent, non-polluting, medium molecular weight nonionic saturated carbon chain polymer. Indoor evaluation shows that DY-067 can inhibit the expansion of clay, prevent shale dispersion, reduce fluid loss and mud cake penetration, and can be compatible with common treatment agents. It is a very effective drilling fluid to prevent collapse.
