Abstract

Abstract: The Agadem Oilfield of Niger is located in the Sahara desert area, and the bad natural environment, and drilling rig moving and material transportation difficulties lead to low drilling efficiency and high daily operation cost drilling investment. Based on the analysis of the reservoir new well plan characteristics, we put forward the application of small-scale factory drilling to reduce the well site construction cost, improve the efficiency of the drilling rig moving, so as to improve drilling efficiency and material utilization, achieve the purpose of reducing drilling cost through rig moving process optimization, cluster well site location optimization, well slot and borehole trajectory optimization, casing program optimization, drilling fluid system optimization and reutilization, PDC + motor one trip drilling and cementing quality security technology research. Actual construction application proves that small-scale factory drilling and matching technology apply successfully in the field with remarkable effect.

Key words: desert oilfield, complex fault block, small-scale cluster wells, factory drilling, one trip drilling
