Horizontal well synthetic speed increase technology in Sulige 53 block

Sulige gas field 53 block is low pressure,low permeable block,reservoir buried deep,oil layer is thin,single well production is low.Horizontal well development technology is effective method to enhance single well production and recovery efficiency in the study block.In the drilling process,great well drilling and exploration engineering limited company implemented a series of synthetic speed increase measures as optimizing well casing structure,optimizing drilling fluid system,optimizing drilling parameter selection and deployment,reasonable selection of drilling tool combination and optimizing bit model,which gained remarkable effect in horizontal well drilling,summarized successful experience of Sulige 53 block drilling technology and put forward existing problems.
