Drilling fluid system name

Oil-based emulsion composite plugging system

Matching core finishing agent

Oil-based emulsion compound plugging agent HJD-O

System characteristics

1、The oil-based external phase releases the organic scale/emulsified plugging in the near well zone;

2、The oil-based external phase reduces water saturation in the near-well zone;

3、The oil-based outer phase changes the rock wettability in the near-well zone;

4、The composite organic acid water-based internal phase can partially dissolve the rock minerals, which acts as a pore-expanding effect.

Application situation

The HJD-O oil-based emulsion composite plugging solution is suitable for organic reservoirs caused by silica gel, asphaltene content, high wax content and poor compatibility of crude oil in reservoir. Such as WZ6-9 oilfield production wells, WZ6-10 oilfield production wells, and other production wells with similar characteristics.
