Abstract
The utility model belongs to underground tool for oil extraction of oil field, in particular to a multi-layered production separate-pumping process pipe column which solves the problem of interlayer pressure inconsistency during multilayer production of multi-layered production process of oil well of the oil field, and effectively improves the extraction percentage. The multi-layered production separate-pumping process pipe column comprises an oil pump, a divider, a packer, a ball base, a screen pipe and a screwed plug, the components penetrate through an oil pipe to form a whole from top to bottom, the process pipe column improves the extraction percentage through multi-layered production, the pipe column adopts the divider and the ball base to separate the high and low pressure layers inside the pipe column, the exterior of the pipe column is separated by the packer, the pipe column is applicable to multilayered production and realizes the synchronous mining of the high and low pressure layers, and improves the oil yield; meanwhile, the pipe column also can be equipped with a multilevel packer and a multilevel divider to perform multilayer mining, adapts to different well conditions, reduces the operation cost and effectively guarantees the smooth operation of the multi-layered production.
Description
Technical field:
The utility model belongs to the downhole tool of oil field oil recovery usefulness, be specifically related to a kind of separate zone production technology that is used for oilfield when solving commingling production interlayer pressure contradictory problems and the separate zone whole production branch that effectively improves oil recovery rate take out process pipe string.
Background technology:
Along with continually developing of oil field, separate zone production becomes mainstream development direction gradually, and the difference of interlayer is obvious day by day, as the interlayer pressure contradictory problems, when the high-low pressure layer closes when adopting, high pressure zone can form additonal pressure to the low pressure layer, and then have influence on the liquid outlet quantity of low pressure layer, these contradictions are prevalent in the production well at present, and it has brought very big difficulty to oil production technology, has a strong impact on oil field development effect and benefit.As seen develop a kind of present condition that is applicable to, it is imperative to close new technology, the new technology of adopting branch and taking out to moisture oil reservoir close, different pressures.Solution at this problem mainly is to adopt the method for oil well pump for separated zone operation at present, but the oil well pump for separated zone operation complex structure, reliability is low, and involves great expense, and cost is higher.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of separate zone whole production branch by separate zone whole production raising oil recovery rate to take out process pipe string.
The purpose of this utility model is achieved in that and comprises oil well pump, current divider, packer, ball seat, screen casing, plug, it is characterized in that: described each parts run through into an integral body by oil pipe UNICOM from top to bottom.
Described each parts two ends are threaded, and are connected with the screw thread at oil pipe two ends.
Be a kind of being tightly connected between described each parts and the oil pipe.
The utility model improves oil recovery rate by separate zone whole production, and inner current divider and the ball seat of adopting of tubing string separated the high-low pressure layer, and tubing string is outer to be separated by packer, is applicable to commingling production, and realization high-low pressure layer is exploited simultaneously, increases liquid outlet quantity; This tubing string also can be joined multiple-string packer and current divider and carried out commingling production simultaneously.This tubing string can adapt to different well ' s conditions, reduces operating cost, guarantees carrying out smoothly of separate zone whole production operation effectively.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model comprises oil well pump 1, current divider 2, packer 3, ball seat 4, screen casing 5, plug 6, it is characterized in that: described each parts run through into an integral body by oil pipe 10 UNICOMs from top to bottom.
Described each parts two ends are threaded, and are connected with the screw thread at oil pipe two ends.Be a kind of being tightly connected between described each parts and the oil pipe.The oil pipe that is described each parts of connection is a section, and every Oil-saving pipe has box and pin thread respectively in two up and down.The every joint of the oil pipe of described each parts of connection is between 9-10 rice, and the external diameter of oil pipe is between 70-75mm.7 is the artificial bottom of a well, and 8 is that high (low) presses layer, and 9 is that low (height) presses layer.
The utility model is made up of parts such as common oil well pump, current divider, packer, ball seat, screen casing, plugs. requires each parts to be in turn connected into an integral body according to actual mined bed with oil pipe. can select other kits according to actual conditions simultaneously, the allotment tubing string is convenient. and packer is in current divider and the ball seat between (it), in the tubing string outside high-low pressure layer is separated; Current divider and ball seat and screen casing plug correspond respectively to different pressures layer up and down, and during work, when the relative lower floor of upper strata operating pressure operating pressure was high, last stressor layer can only pass through current divider, will be cut off by ball seat when it enters lower floor; Otherwise when the relative upper strata of lower floor's operating pressure operating pressure was high, lower floor's pressure will be cut off by current divider when entering the upper strata by behind the ball seat, thereby solved the problem of the different mining operations difficulties of interlayer pressure.
By actual mining Design requirement tubing string is arrived the precalculated position down, and make packer setting, Seal Oil cover annular space, the high-low pressure layer is separated outside tubing string, at tubing string inner utilization flow divider and ball seat the high-low pressure layer is separated simultaneously, current divider and ball seat and screen casing plug correspond respectively to different pressures layer up and down, during work, when the relative lower floor of upper strata operating pressure operating pressure was high, last stressor layer can only pass through current divider, will be cut off by ball seat when it enters lower floor; Otherwise, when the relative upper strata of lower floor's operating pressure operating pressure is high, lower floor's pressure is by behind the ball seat, when entering the upper strata, will be cut off by current divider, utilize common taking out not have pump that the high-low pressure layer is carried out noiseless pumping in the pump barrel afterwards, realization high-low pressure layer is opened the purpose of taking out, take their own roads, being independent of each other simultaneously, thus thorough liberation low pressure layer.
