Актуальность. Подземные воды Западно-Сибирского региона характеризуются повышенным содержанием ионов железа, силикат ионов и органических веществ гумусового происхождения. Эти примеси способствуют образованию устойчивой коллоидной системы. При использовании природной воды в качестве теплоносителя на поверхности труб формируются силикатные отложения за счет связывания катионов кальция, магния, алюминия, железа. Совместное присутствие силикатов и органических примесей приводит к снижению эффективности очистки воды с применением существующих технологий водоподготовки. Цель: определение концентрационных и температурных условий образования соединений кремния с гуминовыми веществами и скорости их осаждения в присутствии продуктов термической обработки магнезита (каустического магнезита). Объекты: природные воды и модельные растворы, содержащие соединения кремния и растворенные гуминовые вещества, каустический магнезит. Методы: фотоколориметрия, рН-метрия, титриметрия, атомно-эмиссионная спектрометрия с индуктивно связанной плазмой (ICAP-6000). Результаты. Установлен интервал массовых соотношений растворимых гуминовых веществ и силикатов ГВ:SiO32–=0,8–4, в котором гуминовые вещества и SiO32–-ионы при совместном присутствии в интервале рН=5…9 связываются в органо-минеральные комплексы. В природных высокоцветных водах (содержание органических веществ до 30 мгО/л) до 40 % силикат ионов может быть связано в такие комплексы. Размер образующихся коллоидных частиц составил порядка 200 нм, значение ζ-потенциала составило –38 mV. При использовании каустического магнезита в качестве реагента-осадителя взаимодействие в системе «силикат–гуминовые вещества» протекает в две стадии, определяющие технологическую целесообразность одновременного удаления из воды силикатов и гуминовых веществ.

Объектом исследования являются продуктивные пласты юрских отложений месторождения Шаимского нефтегазоносного района, характеризующиеся высокой степенью неоднородности и низкими значениями фильтрационно-емкостных свойств, осложнёнными тектоническими нарушениями. Недостижение проектных показателей выработки запасов нефти для подобных месторождений требует проведения детального мониторинга разработки с учетом ключевых геологических характеристик и последующего регулирования и совершенствования системы разработки. Методический подход к совершенствованию системы разработки месторождений, осложненных тектоническими нарушениями, должен включать критический анализ первичной геолого-геофизической и промысловой информации, анализ основных показателей разработки, характеризующих выработку запасов нефти. Цель работы: определение причин неравномерности выработки запасов по площади и разрезу продуктивных пластов, изучение влияния тектонических разломов различного порядка на эффективность реализуемой системы разработки, в том числе и на систему заводнения продуктивных пластов. Методы исследования: геолого-гидродинамическое моделирование разработки, геолого-промысловый анализ разработки, анализ результатов интерпретации гидродинамических исследований скважин, сопоставительный анализ фильтрационно-емкостных свойств пласта, полученных различными методами исследований. Анализ эффективности системы разработки проводился с использованием косвенных методов математической статистики, подкрепленных прямыми методами – трассерными исследованиями скважин. Результаты. На примере Новомостовского нефтяного месторождения выделены гидродинамически обособленные участки с высокими значениями подвижных остаточных запасов, ограниченных тектоническими нарушениями, для которых предложены геолого-технические мероприятия и технологии, направленные на повышение выработки запасов нефти. По результатам проведенных исследований предложено методическое обоснование оперативного регулирования и мониторинга разработки пластов, осложненных тектоническими нарушениями.
