Description
Technical field
The present invention relates to a kind of polyamine shale control agent and preparation method thereof.
Background technology
Drilling fluid refers in oil/gas drilling process, meets the general name of the various circulating fluid of drilling well demand with its several functions.The function of drilling fluid mainly contains: carry and suspend drilling cuttings; Stabilizing borehole and equilibrium strata pressure; Cooling and Lubricator drill bit, drilling tool; Transmit water power.
Along with the development of petroleum exploration domain, deep-well, ultra deep well, the appearance of ocean well and complex ground well, drilling well difficulty increases, also more and more strict to the requirement of drilling fluid system.Particularly in oil gas drilling process, when boring chance mud shale stratum, hydration swelling, the dispersion of mud shale will cause the series of problems such as borehole well instability, bit balling and hole cleaning.Traditional oil base drilling fluid, possesses many good performances, but its contaminate environment, application is restricted.The high performance water-based drilling fluid being main shale control agent with polyamine class becomes with its environmental protection, low cost, the characteristic such as functional the study hotspot that countries in the world oil investigator pays close attention to.
Polyamine base polymer is as main shale inhibitor, its mechanism of action is: worked by the distinctive absorption of amido, low molecule amine penetrates clay layer as potassium ion, the exchangeable cation of the subsidiary hydration shell of amine desorb of lower concentration, together with by electrostatic adhesion, hydrogen bond action and dipole effect etc. clay lamella being strapped in, stop water molecules to enter, play the effect that shale suppresses.
Polyamine class shale control agent is mainly based on macrocation, small cation.Macrocation is polyamine methacryloyl amine quaternary ammonium salt, as suppressed dose of clay bag; Small cation is epoxypropyltrimethylchloride chloride.Small cation molecular weight is little, with positive charge, is easily adsorbed in surface of clay, and enters between clay seam, replaces exchangeable cation and is adsorbed in wherein.And the surface at its binding molecule place is the hydrophobic surface containing hydrocarbon group, is conducive to stoping water molecules to enter, therefore effectively can suppresses hydration swelling and the dispersion of clay.
Polyether monoamine inhibitor is the ULTRADRIL that MISWACO company of the U.S. releases in recent years
tMhighly inhibited water-base drilling fluid.It is the people such as Patel develop be not hydrolyzed, completely water-soluble, low toxicity and with other conventional water-based drilling solution additive compatibility, its shale inhibition can be better than size cationic polymers.
All kinds of performance of drilling fluid that it is shale control agent that Chinese patent CN 1069755A describes with large small cation, size cationic drilling fluid system shale inhibition can be better.US Patent No. 7012043 B2 describes polyether monoamine inhibitor, and such inhibitor shows good mud shale rejection ability.Macrocation backbone structure or be connected with C-C key between side chain with main chain, branched fraction contains C-N key; Small cation is containing C-C, C-N ,-O-key.Polyether monoamine inhibitor based on C-C ,-O-, in chain or the end of the chain contain a small amount of C-N key.The result that the basic reason of the strong rejection capability of polyether monoamine is in its main chain or a small amount of multiple amido of the end of the chain acts on simultaneously, therefore ability of its constraint hydration and expansion of clay is stronger, shows strong rejection capability.CN201110313847.1 describes a kind of preparation method of cationic polyamine shale control agent, to hold diamines, cyclic ethers, epoxy chloropropane for raw material, obtained after polymerization.Although this shale control agent inhibition is given prominence to, the compatibleness of itself and drilling fluid system needs to improve further.
