Metal soluble bridge plug

Introduction to metal soluble bridge plugs

Suitable for 25 ℃~204 ℃ temperature range.

A variety of material combinations are available to meet the requirements of different blocks.

Short structure, simple design, integrated anti-setting design.

The material is more than 40% less than the conventional bridge plug, which is more conducive to dissolution.

100% metal soluble material can be achieved and completely dissolved within 5 days.

The metal surface is refined and can be sprayed with acid-resistant, water-soluble and anti-corrosion surface to adapt to the construction well soaked by acid injection.

Applicable to all current casing steel grades (P110/125/140 etc.)

The inner diameter maximization design is conducive to flowback after fracturing and does not affect production.

The miniaturized design, which can achieve 67-73-77 mm outer diameter, is suitable for small hole operation and effectively reduces the risk of well entry.

Metal soluble bridge plug - single slip narrow rubber tube soluble bridge plug

Single slip structure, compact structure, integrated anti-advance sealing mechanism, bridge plug body length is short, easy to go down well, with good passability and construction safety.

The metal ceramic composite slip tooth nail is anchored firmly and can be recovered by strong magnetic salvage.

Soluble narrow rubber cylinder reduces soluble rubber volume by 60%.

Small size, large inner diameter, rapid dissolution, conventional well conditions can be completely dissolved within 7 days.

Non-integrated center tube structure, efficient dissolution.

Metal soluble plug - double slip soluble plug

The double-slip structure has smooth seat seal shape, small outside diameter of bridge plug body, large seat seal radius, integrated anti-advance seat seal mechanism, and good passability.

The metal ceramic composite slip tooth nail is anchored firmly and can be recovered by strong magnetic salvage.

The upper slip adopts the integral structure and the ultra-small embedded slip studs. The lower slip adopts the split structure and the standard embedded slip studs.

It can adapt to harsh well conditions, and can enter the well twice under certain conditions, providing a reliable fracturing construction environment.

Ensure construction safety

Application suggestion

It is suggested that the best tool combination should be adopted according to the field situation

When the toe end of horizontal well and wellbore environment are not ideal, or even long downtime situation, it is suggested to use double slip long rubber tube dissolvable bridge plug.

Fracturing immediately after downhole. In general, single slip narrow rubber tube dissolvable bridge plug is used in good well conditions.

Fracturing immediately after downhole, and all-metal soluble bridge plug is used in good well condition. (Small volume, quick dissolution rate)

The combination of the above tools can greatly shorten the plug sweeping operation time. 

It is recommended to adopt those below measures at the same time.

Shut-in is suggested. Shut-in is beneficial to formation temperature recovery and formation induced fractures. In 2021, URTEC published a paper confirming that soaking has such an effect.

It is suggested to adopt chemical sand control measures, such as closing coated sand, to avoid sand production in wellbore.

Reasonable control of blowout pressure.

Dissolvable bridge plugs of special size and special purpose can be customized according to customer requirements.
