Study Of The Properties With Polymer Wax Paraffin Inhibitor

The reservoir of Changqing oil field is typically low permeability, which itselfhas a low formation pressure, low permeability characteristics, the application of arelatively mature, traditional drill (completion) technology caused great harm toreservoir. Considering low permeability of Changqing oil and gas fields, this paperproposes the introduction of circulating foam drilling technology, the pressure controldrilling technology and circulating foam drilling technology combined as a newaproach, and change the technical evaluation of the feasibility and gas protection,from the theoretical, foam system, process, equipment, tools supporting other aspectsof Changqing gas field can be circulating foam control pressure drilling mode to study,eventually forming a suitable circulating foam pressure control drilling technology inChangqing gas field, control and optimization of foam, bottom hole pressureformulations to reduce gas injuries, to maximize the protection gas, truly reflect thereservoir properties and the real capacity of Changqing gas field to provide a reliablebasis for effective development.Through successful application to several wells, confirmed the reservoirprotection, find gas formation, low-cost development of oil and gas resources andreduce risk of a number of well leakage targets can be achieved, thereby improvingdrilling efficiency and achieved comprehensive benefits in low permeability oil andgas fields of Changqing...
