[ Abstract ] has the depositional cycle in view of the double river oil field reservoir complex, rhythm changeable, thick oil layer growth, in level band many, the lithological character is complex, the nature changes in a big way, anisotropic extremely serious characteristic, and the reservoir swelling clay mineral was creates the reservoir harm the latency, in the room develops one kind of new polysaccharide well drilling fluid system. This system through increases one kind of low seepage to drill the processing medicinal preparation as well as many kinds of and duplicate falls the dehydration medicinal preparation but to match several different formulas, the optimal one formula does the further performance evaluation experiment. The experiment indicated that, it has a better thermally stable anti- warm 130℃ , the rheological property, the lubricating ability (lubrication coefficient 0.15 --0.16), anti- (25%), the anti- calcium (2.4%), the suppression ( returns-ratio is 91.2%), thixotropic, the reservoir protection (has good to different hole core sample and crack seals off ability, compressive strength is higher, can effectively protect reservoir) and so on the characteristic, has solved the above double river oil field reservoir existence problem well .
