Description
Technical field
The present invention relates to petrochemical industry, be specifically related to a kind of definite hyposmosis oil well and rationally, take out the method for system.
Background technology
In LOW PERMEABILITY OILFIELD DEVELOPMENT process, along with stratum energy obviously declines, the phenomenon of well deliverability deficiency is very general.Because product is taken out imbalance, oil pumper is for a long time in inefficient operation state, and energy dissipation is serious, and the invalid wearing and tearing aggravation of equipment, causes economic benefit very low.
At present each elephant for poor efficiency well, substantially all adopts between the mode of taking out produce, but for ease of management, conventionally adopt unified fix between take out system.Be generally by well head set-up time controller, to control the start and stop of oil pumper, this time controller is normally controlled the working time of oil pumper by the time interval arranging in advance.This control mode is manual control mode in fact, the time interval of its control is rule of thumb to come to determine completely, owing to not considering the actual feed flow situation in down-hole, just likely produce following two kinds of situations: one, arrange too short interval time, cause down-hole liquid level not recover just to start to produce with rational position, cause the waste of electric energy; Two, arrange interval time longly, cause down-hole liquid level to reach rational position and do not produce in time, oil well effective production time shortens, and causes oil well output to reduce, and fails to bring into play capacity of oilwell.Between unified fixing, the system of taking out is unfavorable for taping the latent power and energy-conservation, therefore, must want specific well conditions to make a concrete analysis of according to different poor efficiency wells, adopts between different and takes out system.
Summary of the invention
The present invention is intended to propose a kind of new method that is applicable to the rational production cycle of low-permeability oil deposit of scientifically formulating.
Definite hyposmosis oil well is taken out a method for system rationally, comprise well downtime T2 and oil well well opening time T; Wherein,
