Abstract
composições de perfuração de poço. uma composição de lama de perfuração a base de água pode incluir um carreador aquoso, um sal sulfonato de asfalto e partículas de látex insolúveis. as partículas de látex insolúveis promovem a estabilização de uma emulsão formada em resposta à introdução de uma fase oleosa na composição. a composição pode incluir a emulsão incluindo uma fase oleosa dispersa como gotículas no carreador aquoso. as partículas de látex insolúveis dispersas podem estar presentes em uma interface de óleo-água entre a fase oleosa e uma fase aquosa do carreador aquoso.well drilling compositions. A water-based drilling mud composition may include an aqueous carrier, an asphalt sulfonate salt and insoluble latex particles. the insoluble latex particles promote the stabilization of an emulsion formed in response to the introduction of an oily phase into the composition. the composition may include the emulsion including an oily phase dispersed as droplets in the aqueous carrier. The dispersed insoluble latex particles may be present at an oil-water interface between the oil phase and an aqueous phase of the aqueous carrier.
