A Study On Advisable Submergence Depth Of Polymeric Compound Rod Pumped Well

The experiment used solution which blend both crude oil and water comes Daqing field. According to the vertical pit shaft conduit flow simulating experiment apparatus,it can have a research about interior polymeric compound liquor and polymer—crude oil conduit flow experiment research. Pursuant to the theory of non-Newtonian liquid dynamics, combinate to production stream rheological behavior test of conduiting flow experiment and the different drive phase, establish the mathematical mode(oil well out performanc) of rod pumped well vertical conduit flow friction calculation which only has bucket rod, dixie grip, sucker rod coupling and insert tubing splice in such three different condition. In the light of the theoryf of fluid mechanics in porous medium, consulting and following dynamic core flow test antecedently and mathematical model of flow event in the oil layer, amending the pattern utilizing the data plotmineral of oil spring, define inflow performance relationship model which is fit for the Daqing oil field coalescing and actuating rod pumped well.Analyse the bearer component of Stringocephalus of rods,we will look the down stroke and upstroke of movement of beam pumping unit as two situation,and will have a research. Analyse and make definite computational method of pump efficiency, establish the math model which are about move forward pump regular pattern of well production fluid and bearer compute of column. Combinate the kinematic regular patter of beam pumping unit point of suspension, consider the coefficient of admission of pump comprehensively, elastic deformation of tube and so on, built up the compute mobel of polymkeric substance which are the inside efficiency and thesurface of the earth efficiency, propose the compute approach of system efficiency.By means of drawing up calculator program to proceed computational analysis, verify and amend pattern which is polymeric compound rod pumped well advisable submergence depth,and confirm changing regular pattern of rod pumped well of advisable submergence depth in the affecting factor, establish advisable submergence depth pattern ,which is semiempirical and semitheoretical. Consider the producing characteristic of polymeric compound rod pumped well, unite rheological behavior of polymeric compound distinct phase,in the prerequisite of insuring outcome require of polymer oil well,take feeding and rowing harmonization as the rule,take the high system efficiency and low energy consumption as object function,establish math model of submergence depth optimize.It can define the minimal submergence depth, largest submergence depth dividing line and optimum submergence depth of different phase.
