Product description
Single-cylinder double-well technology is an advanced conduit sharing drilling technology, which is suitable for the development of offshore marginal oil fields and adjustment wells. With this technology, two directional wells can be drilled in a well. When the space on the offshore platform is limited, under the limited wellbore, more boreholes can be drilled, equivalent to two wells share a well of risers, used in cluster well platform.
Features:
1. There can be two separate wells in a single conduit;
2. Two separate wells each have their own oil casing string at different depths;
3. Effectively reduce the number of mining platforms, and reduce platform development costs;
4. Metal to metal sealed oil casing hangers design;
5. Achieve independent exploitation of oil and gas layers.
