Hydraulic negative pressure unblocking, increasing production and injection technology

详细说明

Technical Introduction

The hydraulic negative pressure plugging and increasing production and injection technology has the characteristics of fewer construction equipment, shorter construction time, and significant effects. It relies entirely on high-pressure flushing fluid to provide power, has strong sand carrying capacity, good well control safety, and no safety and environmental hazards. It is a physical method plugging technology.

Technical advantages

1. The construction equipment is simple and the construction time is short.

2. Strong sand carrying capacity helps to remove blockages from the formation.

3. Good well control safety and low construction risk.

4. It can be combined with conventional acidification for composite unblocking, with better results.

Adapt to well conditions

1. Oil and water wells in sandstone reservoirs mainly composed of mudstone cementation.

2. Oil and water wells blocked by inorganic substances such as mud, silt, mud, and impurities.

3. Oil and water wells that require unblocking and backflow due to contamination caused by external fluids on the formation.

4. Conventional oil and water wells that require unblocking.

Equipment requirements

1. One set of pump trucks with a size of 400 or above, one sewage tank, and several clean water tanks.
