Jilin Fulongquan Area Drilling Speed Up Technology Research

At present,the oil play an important role in People’s Daily life,become a kind of material we are indispensable.Our demand for oil is growing,and the importance of oil exploration work is increasingly remarkable.A series of oil exploitation and exploration work is more important.While in oil exploration work of the most important is the speed of drilling problems,factors affecting drilling speed is also various.So now how can greatly improve the speed of drilling has become an urgent need to solve the problem.This is we need to focus on the optimization of drilling technology,constant innovation.Oil rapidly increase was launched,through to the Jilin oil field Fulongquan block some actual problems encountered in the drilling,through to the bit improvement,optimization of the screw,the borehole mud applications,and down hole accident prevention detailed discusses the measures of accelerating the effect and the matters needing attention and received.The oil and gas field is located in the Fulongquan county agriculture and Changling county of jilin province at the junction,distribution for large area of oil and gas in this area of low pressure,low permeability,low yield of gas reservoir,the development is difficult.Because of its special geological structure,which leads to the increase in the number of complicated conditions encountered in the process of drilling,drilling speed decreased,increased costs at the same time,this will directly affect the Fulongquan region the process of exploration and development.In order to better drilling construction,the production of the rational development of underground resources,to reduce the accidents and the complicated and caused great economic losses,we completed Wells in this area and typical accidents and complex situation has carried on the detailed analysis,studies the characteristics of formation optimizing drilling technology of mature and develop a series of practical construction measures,and applied to the drilling production,greatly improve the drilling speed in the block.Fu230 compared to the rate of penetration of 3.73 m/h,Fu233 Wells,on average,mechanical drilling velocity to 4.33 m/h,than in Fu230 increased by 16.1%.Also greatly shorten the drilling cycle at the same time,by Fu230 of well drilling cycle 58.14 days to 46.02 days.At the same time in the screw and the use of the bit are greatly reduced,created a considerable economic benefits.
