Abstract
The utility model relates to a double fluid dual pumping pump with oil production by layer and two sets of layer systems. The utility model solves the problem of interlayer interference of the two sets of layer systems of an oil field. The utility model is characterized in that the inner screw of a ball seat (2) with a plurality of holes is connected with one end of a convex center pipe (8), causing that the top of the ball seat (2) is contacted with a boss of the center pipe (8) through a sieve pipe (7); a ball seat (5) is pushed by a top thread (6) and is contacted with a valve ball (4) is arranged in a hole of the ball seat (2), wherein, the ball seat (2) and the center pipe (8) corresponding to the valve ball (4) are provided with via holes. The utility model has the characteristics of double fluid and dual pumping; simultaneously, the construction is simple; the hierarchical yield calculation, the pressure test, etc., can not be disturbed; the cost is lower.
Description
Technical field:
The utility model relates to a kind of oil well pump that oilfield uses, and belongs to two feed liquor oil well pump for separated zone operation of two cover series of strata oil productions by layer.
Background technique:
At present, in the oil recovery process of oil field, under the situation that reservoir physical property differs greatly, two cover series of strata adopt single pump exploitation, exist the problem of interlayer interference like this, are unfavorable for giving full play to the potentiality of oil reservoir, influence the output in oil field, the oil reservoir injury relatively poor relatively to rerum natura is bigger.And the double pump exploitation is often adopted in the oil field, though can satisfy the purpose that two cover series of strata branches are adopted, double pump is in the process of going into the well, the rod tube length calculation is difficulty relatively, and working strength of workers is big, the operating expenses height, make and the also corresponding raising of cost had a strong impact on field produces.
Summary of the invention:
In order to overcome the problem of prior art interlayer interference, the utility model provides a kind of pair of feed liquor oil well pump for separated zone operation, and this pump can be avoided interlayer interference and realize separate zone production.
The purpose of this utility model can reach by the following technical programs: this oil well pump for separated zone operation is made up of hollow connecting rod, valve cover and change discount, the hollow connecting rod periphery connects change discount and valve ball seat by box cupling, there is ball seat internal thread connection convex center tube one end in some vertical holes to make tee top touch the center tube boss mutually by screen casing, in the hole of ball seat, have pushed up mutually by jackscrew and touch the valve ball ball seat mutually, there is through hole at wherein corresponding with valve ball ball seat and center tube place, and the center tube the other end is connected with the box cupling that becomes discount.
Vertical hole of above-mentioned ball seat is 6.
The utility model has following advantage than above-mentioned prior art: because there is through hole at the ball seat and the center tube place of valve ball correspondence, when making exploitation, liquid can and become discount feed liquor respectively, the purpose that satisfied branch is taken out from screen casing; The while easy construction, hierarchical production calculating and pressure test etc. are interference-free, and cost reduces greatly.
Description of drawings:
Accompanying drawing 1 is that structure of the present utility model is cutd open figure.
1-valve cover among the figure; (2,5)-standing valve ball seat; The 3-hollow connecting rod; 4-standing valve ball; 6-ball seat jackscrew; The 7-screen casing; The 8-center tube; 9-becomes discount.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, this oil well pump for separated zone operation is made up of hollow connecting rod 3, valve cover 1 and change discount 9, hollow connecting rod 3 peripheries connect change discount 9 and standing valve ball seat 2 by box cupling, and valve ball seat 2 has 6 vertical holes, ball seat 2 internal threads connect convex center tube 8 one ends makes ball seat 2 tops touch center tube 8 boss mutually by screen casing 7, that push up mutually and the ball seat 5 that touch valve ball 4 mutually by jackscrew 6 is arranged in the hole of ball seat 2, there is through hole at wherein corresponding with valve ball 4 ball seat 2 and center tube 8 places, and purpose makes liquid to pass through from this hole through screen casing 7; Center tube 8 the other ends are connected with the box cupling that becomes discount 9.
During actual the use, standing valve ball seat 2 is linked to each other with travelling valve cover 1 by box cupling.In oil recovery process, a part of liquid enters in the travelling valve cover 1 by jackscrew 6, ball seat 5, valve ball 4, the ball seat 2 of screen casing 7, standing valve ball seat 2; Part liquid enters in the travelling valve cover 1 by change discount 9, hollow connecting rod 3, and then realizes dividing the purpose of taking out.Hierarchical production calculating simultaneously and pressure test etc. are interference-free, and cost reduces greatly.
Claims (2)
1, a kind of two feed liquor oil well pump for separated zone operation that relate to oil field two cover series of strata oil productions by layer, by hollow connecting rod (3), valve cover (1) and change discount (9) are formed, it is characterized in that: the peripheral connection by box cupling of hollow connecting rod (3) becomes discount (9) and valve ball seat (2), there are ball seat (2) internal thread connection convex center tube (8) one ends in some vertical holes to make ball seat (2) top touch center tube (8) boss mutually by screen casing (7), in the hole of ball seat (2), have pushed up mutually by jackscrew (6) and touch valve ball (4) ball seat (5) mutually, wherein corresponding with valve ball (4) ball seat (2) and center tube (8) have been located through hole, and center tube (8) the other end is connected with the box cupling that becomes discount (9).
2, according to claim 1 pair of feed liquor oil well pump for separated zone operation is characterized in that: vertical hole of ball seat (2) is 6.
