Analysis Of Sampling Error Of Production Parameters Of Experimental Oil Well Installed Multicup Isoflux Gas Anchor And Its Applications

The multicup isoflux gas anchor is experimentally applied in Daqing Oil Field, and its experimental application effect evaluation has big workload,which need a lot of manpower and material resources and time,and relating to promotion prospects of the multicup isoflux gas anchor in oil field.So it can provides a highly efficient and reliable method of mathematical statistics for the experimental application effect evaluation of the multicup isoflux gas anchor that to study analysis of the sampling error of the production parameters of the experimental oil well installed the multicup isoflux gas anchor and its applications.Based on the basic theory of the sampling error and the confidence interval of mathematical statistics,the calculation method of the sampling error and the confidence interval of the production parameters of the experimental oil well,which are used to evaluate the experimental application effect of the multicup isoflux gas anchor,was given in this paper;the influence rules of the confidence level,the number of sampling measurement oil well,the oil well number to be evaluated and amplitude of wave of single well production parameters on the sampling error of the production parameters of the experimental oil well installed the multicup isoflux gas anchor,were analysed;the program“The calculation and analysis of sampling error of production parameters of the experimental oil well installed the multicup isoflux gas anchor”was programmed;with the program mentioned above,the sampling error and the confidence interval of the production parameters,which are the liquid producing capacity,the oil production and the submergence depth,of experimental oil well installed the multicup isoflux gas anchor of the First,the Third and the Sixth Production Plant of Daqing Oil Field were calculated and analyzed,with which the evaluation of the experimental application effect of the multicup isoflux gas anchor of the First,the Third and the Sixth Production Plant of Daqing Oil Field was realized by using the method of mathematical statistics.
