Oil soluble temporary blocking agent

The oil-soluble temporary blocking agent is an acid-insoluble bridged temporary plugging material processed by a specific process from special natural polymer fiber and resin containing a plurality of reactive functional groups, which has a high strength, suitable particle size distribution, leakage prevention and plugging effect and is apparent for acid sensitive or water sensitive oil layers. It is widely used in the preparation of working fluids such as drilling fluids, completion fluids, workover fluids, kill fluids and acid fluids, and can also be used as a bridge plugging material.

The product is non-toxic, does not pollute the environment, and has good compatibility with other treatment agents; it can form a strong cushion on the well wall of the micro-fracture formation of sand shale and mud shale, so as to improve the strength of the well wall and reduce the permeability of the mud cake,reduce the drilling fluid leaks to the oil layer and protect the oil and gas layer. after temporarily sealed , the oil layer isunblocked for the product is easily dissolved . In the case of large pore loss, it will be better to be combined with other plugging agents.
