Application Analysis Of Deliverability Test In Changling Gas Field Development

With the increasing amount of natural gas,the demand for gas well production is also getting higher and higher.Continued exploitation of natural gas makes the formation pressure lower,while mining more and more difficult.Domestic and foreign experts in the gas well production technology has done a lot of research,have been considerable results.Gas well deliverability is an important index to characterize gas reservoirs,and is an evaluation of reservoir development potential.The current primary task,how to more effectively carry out gas field dynamic monitoring and interpretation assessment research work.For example,in the natural gas production management,the focus on the dynamic monitoring of gas fields,through the relevant static data acquisition,analysis,to meet the needs of information and dynamic analysis needs for the rational development of gas fields to provide a strong basis for accurate understanding,development The purpose of gas reservoirs should be to strengthen the understanding of these methods in obtaining unimpeded flow and well control reserves,and gas well testing to properly shut the time.Production capacity test technology is an important means of dynamic monitoring of gas field development.What are the most pressing problems to be solved by the test technician? Is to solve the problem of gas field development by analyzing the test data to solve the problem of complex geological conditions.Or how to use well data to diagnose the contradiction between gas field development,which has become an effective means of testing data.Therefore,the severe development of the production capacity of the test technology has brought new challenges,but also brought a rare opportunity for development,test technology will continue to resolve the development of contradictions at the same time,the gradual development and improvement.In this paper,the development process of production capacity test technology is summarized.Taking Changling gas field as an example,the practical application of test data in gas field development process is studied,and the guidance function of different productivity test data in gas field development process is analyzed.At the same time,through the analysis of the single point formula,the main parameters that affect the calculation of the absolute open flow rate are the deliverability coefficient α,which is corrected and the corrected deliverability capacity coefficient is brought into the theoretical formula of the single point method.The new Changling gas field Empirical formula.Through the error analysis,combined with geological and field conditions,the conclusion is drawn that the new formula is more consistent with the actual flow of Changling gas field.
