Recently, the drilling operation of a production well in Bohai that was drilled by the Kan-6 platform of the Shanghai Bureau of Petrochemical Industry Co.
, Ltd.
was successfully completed, marking the success of the first battle of the Kan-6 platform in the "single-bore double well"
.

The "single-bore double well" is a highly difficult well.
The maximum inclination of this type of well is up to 60 degrees, and the Kan-6 platform has never been operated
.

Due to the limited space of the production platform and the number of slots, in order to save production costs, more wells are drilled with limited well slots and risers.

In order to ensure the safe and smooth operation, six measures were taken simultaneously, the anti-collision plan was strictly implemented, and the directional drilling of the first well of the "dual well" was completed according to the designed trajectory, and sufficient space was reserved for the second well
.

The use of new technology and technology-occupying drilling tool technology, transformation of related supporting tools, refined technology and optimized design, realized safe and efficient operation, effectively shortened the construction period, and completed the task two days in advance
