Description
Technical field
The present invention relates to a kind of fluid loss agent, relate to a kind of high-temperature resisting and salt-resisting fluid loss agent and preparation method thereof particularly.
Background technology
Along with the development of petroleum industry and the continuous growth of petroleum demand, oil-gas exploration and development is gradually to deep formation and marine development, and the difficulty of drilling engineering is increasing, proposes requirements at the higher level to drilling fluid and additive for drilling fluid.Fluid loss agent, as one of the important process agent of water-base drilling fluid, plays an important role to the safe, fast, efficient drilling well of guarantee.Its consumption is maximum, and of a great variety, is mainly natural materials or natural materials modified product and synthetic polymer class.Natural materials or natural materials modified product comprise humic acid, Mierocrystalline cellulose, xylogen, starch based and derivative thereof; Synthetic polymer is mainly based on various vinyl monomer multiple copolymers and sulfomethylated resol etc.Under certain condition, some mineral compound such as calcium carbonate superfine powder, silicon ash also can be used as fluid loss agent.In recent years, in order to meet the needs of complex stratum condition safety drilling, the research of high temperature resistance, salt resistant drilling fluid loss agent is progressively paid attention to.And polymer class fluid loss agent enriches due to monomer whose classification, adjustability is strong, has broad application prospects in high temperature resistance, anti-salt, just progressively becomes the focus of research both at home and abroad.
Since twentieth century six the seventies, external just to fluid loss agent, particularly high-temperature resisting and salt-resisting fluid loss agent has been cooked a large amount of experimental studies, and also achieves good real world applications effect at the scene.As early stage SSMA (Zelan 338), VSVA (vinyl sulfonate and ethernamine multipolymer), the rare amide copolymer of methyl-prop of Soviet Union's development, the Hostadrill (ethernamine vinyl sulfonic acid salt copolymer) of West Germany's development and Resinex (valchovite) etc. produced in USA; The Driscal series product having U.S. Xue Fulong-Karen Phillips company to produce be widely used in the recent period.
China's additive for drilling fluid obtains in the 1970s and 1980s in 20th century and develops rapidly, and it is acrylamide, the acrylic-multipolymer class treatment agent of representative that period defines with PAC-141, has walked abreast into corresponding polymer drilling fluid system.There is the both sexes complex ionic additive for drilling fluid and the drilling fluid system that take FA-367 as representative in the nineties, polymer drilling fluid Technology is had again new development, compared with anionoid polymerization, amphoteric ion type polymkeric substance flocculation and anti-collapse in make moderate progress, but the restriction of the polymerization activity due to cationic monomer used, the introduction volume of cationic monomer is limited, there is no rapid progress improving in the over-all properties of polymkeric substance.Studies in China work in the last few years mainly concentrates on the multi-component copolymer objects system based on acrylamide, temperature resistance and the anti-salt property of product is improved by introducing sulfonation group and rigid chain segment on molecular chain, but in actual use, these products are all difficult to the high temperature bearing more than 200 DEG C, high-density weighting material is caused to precipitate, saline-alkaline tolerance declines, and cannot meet the requirement of deep & ultra-deep well.
Summary of the invention
The object of this invention is to provide a kind of novel high-temperature resisting and salt-resisting fluid loss agent material and preparation method thereof, to solve the poor problem of existing water-base drilling fluid fluid loss agent heat and salinity tolerance ability.NIPA (NIPAM) has stronger stability to hydrolysis and heat and salinity tolerance performance, simultaneously owing to having hydrophilic amide group and hydrophobic sec.-propyl in molecule, its homopolymer is made to have temperature sensitivity, at Kraft point (LCST) (40-65 DEG C) below, the uniform solution of the water-soluble formation of its homopolymer, when temperature rises to more than Kraft point, solution is separated.Given this characteristic, this monomer is introduced acrylic amide water-soluble polymers main chain, the multipolymer of preparation has responsive to temperature type equally, when temperature is lower than LCST, the interaction of macromolecular chain polar groups and surrounding water molecules is better than the interaction between hydrophobic grouping, macromolecular chain is water-soluble, and soltion viscosity is lower, is easy to situ configuration glue; When temperature is higher than LCST, the polar group extent of hydration of macromolecular chain reduces, hydrophobic segment in NIPAM is separated out from solution, produce in molecule and Interpolymer Association, increase hydrodynamic volume and make drilling fluid have good shear force with suspension high-density weighting material, and in salt-water drilling fluid, because solution polarity increases, heat resistance and salt tolerance is strengthened, obvious anti-salt property can be shown.Therefore, the introducing of NIPAM, can improve the heat and salinity tolerance effect of acrylic amide fluid loss agent.
