Composition and placement process for oil field chemicals |
摘要 |
Oil field chemicals are incorporated in microcapsules of the condensation product of hydroxyacetic acid or the co-condensation product of hydroxyacetic acid and other compounds containing hydroxy-, carboxylic acid-, or hydroxycarboxylic acid moieties. The microcapsules are then introduced into an oil well bore and/or subterranean oil formation where the microcapsules dissolve over a period of time and release the oil field chemicals.
