精细与专用化学品

针对目前在油田广泛应用的化学堵水体系存在黏度高、强度低、有效周期短、注入难度大等问题，开发出一种无固相、易注入、具有深部封堵的颗粒型调堵体系。该体系注入地层后由地层温度激发发生液固转化生成固体堵水颗粒，形成的颗粒能进入孔喉形成封堵。在渤海某油田油井应用证明，该体系可有效降低油井含水率，8个月内累计增油3050m³,可为海上提产增效提供了新的思路。

Currently, chemical water shutoff systems widely used in oilfields face issues such as high viscosity, low strength, short effective duration, and difficulties in injection.In response to these challenges, this study developed a solid-free, easily injectable particulate profile control and plugging system capable of deep reservoir blockage.After being injected into the formation, this system is activated by the formation temperature to undergo a liquid-to-solid transformation, generating solid water-plugging particles.The formed particles can enter pore throats to create effective blockages.Field application in an oil well in the Bohai Sea oilfield demonstrated that this system effectively reduced the well's water cut and has achieved a cumulative oil production increase of 3050m³ over eight months, offering a new approach for enhancing production and efficiency in offshore operations.
