Abstract

In response to issues such as wellbore leakage, coalbead water sensitivity, and pulverized coal plugging in the Yuwang coalbed methane reservoir, a nitrogen drilling software was independently developed. Suitable gas injection parameter calculation models and friction torque calculation models for coalbed methane nitrogen drilling were established. The calculation methods for construction parameters such as gas injection volume, injection pressure, friction torque under different working conditions, and erosion wear of the drill string were clarified. The drilling tools for horizontal well nitrogen drilling technology were analyzed and selected, and one directional test well and one horizontal production test well were drilled in the Yuwang Block in Yunnan. During the actual construction process, the calculated injection pressure values were within 10% error range of the actual values. No accidents occurred due to friction torque and erosion wear of the drilling tools. The mechanical drilling speed reached 11.64 m/h, which is three times the drilling speed of the adjacent wells, verifying the high accuracy of the software. This study provides a reference for nitrogen drilling in coalbed methane reservoirs.

Key words： coalbed methane; horizontal wells; nitrogen drilling; friction torque; erosion; gas injection; Yuwang Block
