Abstract
Combined use of gas drilling technique and horizontal well drilling technique can reduce farthest the reservoir damage,augment reservoir exposed area,and is an important technical measure for development low permeability reservoir.The article introduced the main technical problems in gas drilling.At the same time,the applicable conditions,the drilling technology and procedure,the preparation work,the operation methods,the logging technology after completion and the completion technology of horizontal drilling with natural gas were also presented.Combined with the real drilling situation in Guang'an 002-H8 well,the technical problems which should be considered and the technical development orientation were also proposed in horizontal drilling with natural gas.
