Description
Technical field
The utility model relates between a kind of rod-pumped well takes out control device.
Background technology
Pumping production is one of most important mechanical oil production model, and be also oil field power consumption rich and influential family, its power consumption accounts for 40% of oil field total electricity consumption, and overall efficiency is low; The factor of restriction oil pumper energy-efficient operation is a lot, and wherein factor is the balance of the supply and discharge relation of rod-pumped well in very important one; Along with the prolongation of oil-field development time, the continuous exhaustion of producing energy, in well, liquid level constantly declines, and down-hole liquid supply speed is slack-off, and pump degree of filling reduces, low energy well even pumped-off well number gets more and more, the operation jig frequency of oil pumper also should slow down thereupon, otherwise, will cause that pump efficiency is poor, the non-productive work time is long, both waste a large amount of electric energy, turn increase equipment attrition, the probability of damage and maintenance cost; Therefore, change according to well on the beam fluid supply capacity and producing energy and working fluid level and adjust swabbing parameter in time to maintain that supply and discharge balances be an important process.
In actual production, the operation jig frequency of oil pumper can not arbitrarily and infinitely adjust, and when jig frequency can not slow down further, is just necessary open shop between enforcement; So both can save a large amount of electric energy, and also can reduce the wearing and tearing of oil pump rod pump, extend pump detection period.
Oil field low energy inefficient well takes out control between carrying out, and both can save a large amount of electric energy, also can reduce the wearing and tearing of oil pump rod pump, extend pump detection period; Avoid, because rod parting, overload, three-phase imbalance burn out the generation of the major accidents such as motor, improving production timeliness; Take out the common method of control in the middle of prior art and have three kinds: the first, send someone to be timed to well on the beam and remove start-stop oil pumper, this way is time-consuming, and relies on the experience of staff to a great extent; The second, introduces timer clock, and only need set out, between the stopping time, take out control between just automatically completing, this way is difficult to oil pumper duty dynamic response oil well load is changed, and takes out and reach optimum efficiency between cannot ensureing; The third; introduce pick-up unit; realize oil pumper according to well on the beam Production development situation of change open or stop; the third is taken out to the pick-up unit of control mode introducing; having plenty of by detecting current of electric, having plenty of by test pumping-unit workdone graphic, having plenty of by detecting oil pressure and fluctuations in discharge; also have plenty of by detecting level change, and then judge the start/stop machine time.
Wherein, realizing start and stop by level change is the most direct methods; But because the difficulty of long-term dynamics test liquid level is large, cost is high, be difficult to promote; Judge to find time reference mark by the way of testing load-position diagram, be one of method applied the earliest, its major defect is that load transducer long-term work was easily lost efficacy and can only judge point (stop time) of finding time, and cannot the perception on time; By the way of test traffic, oil pressure also because the reason of the aspect such as cost and reliability is not used widely.
For the relevant issues in correlation technique, at present effective solution is not yet proposed.
