Drilling Technology for Jiaoye Well 60-5HF

Abstract:

Jiaoye 60-5HF is a horizontal shale gas well in southeast wing of Jiaoshiba structure with designed depth of 5290m, inclination angle 69.30° , vertical depth of 3945.04m and closed displacement 2513.99m. Several adjustments were made to overcome high temperature, large friction drag, backing pressure and well trajectory intersection to ensure the horizontal section extension along the reservior during the construction; the drilling depth was 5235.00m. It was a horizontal well with the deepest vertical depth in Fuling work area with inclination angle 81.8°, vertical depth 3820.56m, horizontal displacement 2509.53m and horizontal section length 1775.00m.
