Development History and Characteristics of Micro-bubble Drilling Fluids
In the exploration and development of low pressure and atmospheric pressure fractured buried hill reservoirs and energy-depleted reservoirs,if conventional drilling fluid is used for drilling,well leakage will occur frequently,which will not only affect the construction progress,but also drilling fluids can pollute the formation and block the oil and gas hole,resulting in unsatisfactory productivity.Therefore,this paper analyzes the development history and characteristics of the micro-bubble drilling fluid system in the low-density drilling fluid system,which provides a theoretical basis for the rational selection of drilling fluid system when drilling into low-pressure fractured formation in the future.
