Technical introduction:
The branch well technology is suitable for a variety of reservoir development, including: heavy oil or heavy oil reservoirs, layered reservoir systems, fault blocks or isolated reservoirs, low permeability reservoirs and natural fracture reservoirs, etc., using multi-lateral wells Technology can reduce oil and gas development costs, achieve multi-layer production, and improve oil and gas recovery.

Technical features:
1. Increase the length of wellbore in the reservoir, expand the drainage area, and improve the recovery factor;
2. Improve the oil flow dynamic profile, slow down the coning speed, and provide gravity oil drainage path;
3. Increase vertical production of oil and gas reservoirs;
4. Improve fracture drilling rate in fractured oil and gas reservoirs;
5. Economic exploitation of marginal oil and gas reservoirs;
6. The upper section can be reused to reduce drilling cost;
7. Platform construction costs are reduced due to the reduction of surface wellheads or offshore Wells;
8. Reduce costs of oil well management and environmental protection, and improve economic benefits.

Applicable conditions:
        Multiple reservoir development
