Horizontal well penetration rate increasing technology in Daniudi area

Daniudi gas field is one of the five biggest gas fields of SINOPEC. Major problems on horizontal well drilling were analyzed, and technical measures were put forward in aspects of drilling engineering geological environment description, horizontal wells engineering optimal design, coal seam collapsing prevention technology and Measurement While Drilling technology. Popularizing horizontal well drilling matching technology in Daniudi area, which contains high quality drilling fluids technology, expandable tube sealing technology and electromagnetic wave MWD technology could effectively increase drilling rate, and accelerate the process of exploration and development process of Daniudi gas field.
