ДОБЫЧА НЕФТИ И ГАЗА

ОПЫТ ВОЗДЕЙСТВИЯ ASP-ЗАВОДНЕНИЯ НА НАСОСНОЕ ОБОРУДОВАНИЕ

(HISTORY OF ALKALINE-SURFACTANT-POLYMER FLOODING IMPACT ON PUMP EQUIPMENT)

Один из способов увеличения нефтеотдачи пластов – щелочь-ПАВ-полимерное заводнение, или ASP-заводнение. За счет смешивания композиции с пластовыми флюидами жидкость, поступающая в добывающую скважину, приобретает новые, более агрессивные для насосного оборудования, свойства. В работе рассматривается опыт промышленного применения ASP-составов и их влияние на насосное оборудование на месторождениях Китая, Канады и России. Цель статьи – изучение влияния щелочь-ПАВ-полимерного состава на внутрискважинное оборудование при разных геологических и термобарических условиях реализации метода увеличения нефтеотдачи. Задачи работы: рассмотреть влияние ASP-композиции на разные виды насосов; обозначить место в насосном оборудовании, наиболее подверженное повреждениям; проанализировать опыт использования метода в промышленных масштабах. В результате выделены общие факторы, влияющие на солеотложение в насосном оборудовании и снижение межремонтного периода работы скважины. Установлено, что наиболее подвержены повреждениям входные элементы насосного оборудования, а солеотложение зависит от совместимости пластовых и закачиваемых вод, пород-коллекторов призабойной зоны и их химического состава, а также неоднородности пластов. Солеотложение в результате использования ASP-заводнения делает проекты по увеличению нефтеотдачи пласта экономически нерентабельными даже при значительном увеличении коэффициента извлечения нефти.

Alkaline-surfactant-polymer (ASP) flooding is one of the ways to enhance oil recovery rates. Mixing the compound with formation fluids gives new properties to the fluid flowing to the production well, making it more aggressive toward pumping equipment. This paper discusses the history of the use of ASP mixes for industrial applications and their impact on pumping equipment at fields in China, Canada, and Russia. The objective is to investigate how an ASP mix impacts the downhole equipment under various geologic conditions, temperature and pressure when practicing the enhanced oil recovery method. The tasks are: to consider what effects an ASP mix has on various types of pumps; to identify where the pumping equipment is most susceptible to damage, and to analyze the history of using the method at an industrial scale. The study identified common factors influencing scaling in pumping equipment and reduction in well turnaround. It is found that inlet components are the most susceptible to damage in a pump and scaling depends on the compatibility of formation and flood waters, reservoir rocks in the bottomhole area, and their chemical composition, as well as the heterogeneity of formations. Scaling resulting from ASP flooding makes recovery enhancement projects non-profitable even at a significant increase in the oil recovery factor.
