Solid phenolic resin sand sand construction methods and construction process parameters

Different sand method of construction procedures and parameters are different , here focuses on several commonly used chemical sand oilfield construction procedures and parameters .
Phenolic resin solid construction sand and construction process parameters
( A ) perforating : vacuum perforating hole density of 20 holes / m, pore size of not less than 10mm.
( 2 ) wash well : there is no solid well fracking phase with a plus cleaning liquid clay anti-swelling agent, emulsifier and anti- flushing .
( 3 ) through well : with less than 4-6 mm casing diameter wells regulatory pass through to the lower bound of the following reservoir 20m, no Difficult phenomenon .
Anti ( 4 ) under the sand column : Full Wells once sand , light pipe above the upper boundary of the reservoir was completed in 5 ~ 10m, installed wellhead for construction ; multi- layered reservoir sand Nagai segment , using the first down into the packer , from under the previous paragraph by paragraph, sand , each segment length control wells within 20 m.
( 5 ) being extruded activity Diesel : Diesel ceramic proppant was added 1% of polyoxyethylene alkyl ether -8 active agents, i.e. the activity of diesel oil in an amount of not less per m perforation 500 L, CC 300 L / mim.
( 6 ) being squeezed hydrochloric acid : hydrochloric acid concentration of 5% to 7 % per meter reservoir perforation less than 200 L, displacement 300L/min.
( 7 ) being squeezed diesel : the amount of 2m, displacement 300L/min.
( 8 ) being squeezed phenolic resin solution : oil per meter perforation less than 200 L, displacement 300L/min.
( 9 ) n- extrusion pore former ( diesel ) : the amount of resin in an amount of 2 to 3 times the displacement 300L/min.
( 10 ) n- extrusion curing agent ( HCl ) : HCl concentration of 10% to 12%, an amount of 2 to 3 times the amount of resin , the displacement 300L/min.
( 11 ) are squeezed replace liquid ( diesel ) : All hydrochloride squeeze oil displacement 300L/min.
( 12 ) shut Hou Ning 48h or more.
( 13 ) kill , resin surface exploration drilling plug to artificial bottom.
( 14 ) down into the production string production.
