The algorithms for well pump control in well-formation system
M.A. JamalbayovThe influence of various factors on the dynamics of fluid column rising in well borehole with open wellhead in well-formation system is studied. On the basis of computer model of well-formation system, a number of machine investigations have been carried out. A case, when gassed oil is filtrated in the formation considering actual properties of fluids and medium, has been reviewed. It was established that the time necessary for static fluid column formation does not change during development due to the layer pressure. It depends only on transmissibility of bottomhole zone. The criterion for defining of periodical operation regime of well pump is defined. The algorithms for defining of operation parameters of well pump and effective control of its functioning in periodical regime have been developed. Offered algorithms may be used in creation of automated systems of control on well pump in periodical regime.
