The mechanism of action of the present invention:
(1), adhesive aggregation is mended the wall effect
Anti-collapse dose of the present invention is under the bottom temperature effect, splitting action takes place easily, moisture in the bitumen emulsion is separated gradually, pitch particle is coalescent mutually, simultaneously with the adsorption of rock of borehole, pitch particle carries out physical adsorption by molecular chain and rock surface, and the result makes rock of borehole surface form the firm asphalt film of one deck, and it can stop in the drilling fluid free water to be permeated to the stratum on the one hand.When the pitch particulate forms the asphalt membrane with certain intensity on the borehole wall on the other hand, with the influence that can not washed away by drilling fluid.
(2) strengthen the mud cake lubrication
Anti-collapse dose of particle of the present invention is because self viscosity and elasticity produce deformation under fluid column pressure, and further shutoff mud cake mesoporosity forms thin and fine and close mud cake.Its oleophilic moiety is forming the Oil solvent film on the mud cake surface, and its oil dispersible asphalt particle plays good lubrication in drilling fluid.
(3) leak-off and restraining effect fall in reinforcement
Contain a certain amount of polyacrylate among anti-collapse dose of the present invention, polyacrylate exists with emulsion form, and contain a certain amount of potassium ion, in drilling fluid, play and fall leak-off and restraining effect, simultaneously provide complexing action for pitch in the microporosity, stratum and the borehole wall, make the polyacrylate breast grain separated viscosity and the resilient energy intensity that in microporosity, stratum and microfissure, improves the pitch adhesive membrane, improvement of mud cake by self.
The rig-site utilization situation
Anti-collapse dose of the present invention has effectively reduced the down hole problem generation in drilling process, mainly show:
(1) anti-collapse dose of the present invention is good with the cationic polymer drilling fluid compatibleness, and property of drilling fluid is stable, and its adding is non-foaming, it is sticking not carry, and do not influence original property of drilling fluid.Be convenient to safeguard that contamination resistance is strong in the on-the-spot use.
(2) improved the inhibition ability of cationic polymer drilling fluid, effectively suppressed caving in of shale hydration and hard resistance stratum, avoided falling the generation of the lock of tool drilling that piece brings because of the borehole wall that leakage causes.The hole diameter amplification degree significantly descends, and has realized the stable of the borehole wall.
(3) polymer cation pitch helps the shutoff to the stratum microfracture, can effectively reduce wastage, helps reducing drilling fluid cost.
(4) the polymer cation bituminous uses, and the coefficient of friction resistance of drilling fluid mud cake is reduced, and makes it to have good lubricating property.
