Research On Integration And Scale Application Of Rapid Drilling Technology For Factory Well Group In Changqing Dense Oil And Gas

In 8 Wells platform and double six horizontal double row of well group drilling rig construction,formed the factory drilling well site layout patterns,formed the drill fast moving and drilling equipment standard of form a complete set of equipment and so on,mainland China,the construction process optimization to effective,horizontal well bore profile to be optimized,formed a vertical Wells,rectifying section and inclined section and horizontal section of the corresponding trajectory control technology,the factory well group crash-proof has carried on the overall design and calculation,the symmetry of the friction torque of directional well and horizontal well overall theoretical analysis and the frictional drag reduction technology application,Two drilling of directional well,three drilling of two-dimensional horizontal well and four drilling of three-dimensional horizontal well are formed,which effectively improves the efficiency of well group construction.27 Wells were tested in 4 well groups,which saved 21 road before drilling,138 mu of road land area,161 days of construction before drilling,131 mu of land expropriation area of well site and 138 days of moving.The drilling cycle was reduced by 8% and the completion cycle by 10%,resulting in a total cost savings of about 78 million yuan.
