The Research And Application Of Gas Exploratory Well Drilling Technology In Jingbian-gas Field

Jing Nan gas field exploration and development has made certain progress, exploration well drilling speed increased year by year, the formation of exploratory well drilling technology of the following, but there are many problems in the process of drilling, drilling machinery, mainly is the slow formation leakage, hole collapse, seriously restricted the exploration and development of Jing Nan oilfield speed. This paper studies the technology of gas field exploration well drilling in Nan Jing, finds out the factors affecting the drilling speed of gas, respectively, puts forward the corresponding technical measures, By comparing the practice and theoretical analysis, the optimization of wellbore structure, analyze and solve the collapse, leakage, cards and other complex situations, optimizing bit and parameters, the further study of strong inhibition drilling fluid system, fast drilling scheme to realize the optimization of Jing Nan natural gas blocks.
