Description
Technical field
The utility model relates to the ball-throwing apparatus of oil well delamination fracturing technology for a kind of oil field, belong to separate stratum fracfturing ball-throwing apparatus technical field of structures for oil field.
background technology
Ball injector is the separate stratum fracfturing conventional equipment of constructing in oil recovery acidizing fracturing process, particularly stop up ball sleective fracturing technique, this kind of pressure break is that the interval of wanting pressure break in well is once penetrated out, utilize the difference of fracture pressure between each layer, first press off the interval that fracture pressure is lower and carry out gaza, while then noting displacement fluid, drop into and stop up ball, its perforation eye is temporarily stopped up, provide again pressure to open brokenly the interval that pressure is higher, because fracturing work operation pressure is higher, danger coefficient is larger, therefore the ball-throwing apparatus that designs a kind of Long-distance Control and can select at random to drop into the steel ball of different-diameter is significant.
Existing pitching fracturing device is when pitching operates, throw in the input that pipe can only be controlled a ball for one, as need to be projected again the steel ball of same diameter time, need another starting gate to carry out again the input that another throws in steel ball in pipe, this structure operation is got up more loaded down with trivial details, wastes time and energy.
Summary of the invention
Security hidden trouble when the utility model is intended to solve closely controlling that existing pressure break ball-throwing apparatus exists, so provide that a kind of project organization is scientific and reasonable, handling safety reliable, can remote control and can select at random to drop into the separate stratum fracfturing ball-throwing apparatus of different-diameter steel ball.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of separate stratum fracfturing ball-throwing apparatus, its special character is, comprise the ball injector body being installed on the test strobe of fracture well head top, and be connected with described ball injector body and control the control valve group that it completes pitching operation, described ball injector body comprises that top has the pitching cylinder of pitching cover, and a plurality of different-diameters, downward-sloping in described pitching cylinder one side and the dress bulb that is connected with cylindrical shell, the end of described dress bulb is connected with ground described control valve group via high-pressure hose line; The structure of described dress bulb be included in described dress bulb internal vertical to of upper process for holding the ball storehouse cylinder of steel ball, and the ball seat for steel ball described in support of establishing in opposite directions with described ball storehouse cylinder ball mouth, the same diameter steel ball of a plurality of longitudinal arrangements can be equipped with in cylinder inside, described ball storehouse; A side of described ball storehouse cylinder and ball seat be provided with along in described dress bulb circumferentially center tighten up to form the trunnion of high-pressure spray, the opposite side of described ball storehouse cylinder and ball seat be provided be installed on week in described dress bulb for playing the rubber soft rubber stopper of buffer stop effect; Described control valve group comprises a master valve communicating with high pressure pump truck and minute gate being connected with different-diameter dress bulb respectively; By difference, dividing the keying of gate to realize controls the pitching of difference dress bulb;
Described pitching cover by screwed connection in the top of described pitching cylinder;
The cylinder inside, ball storehouse of described dress bulb can be equipped with 2-10 equal diameter steel ball as required;
In order to prevent that described rubber soft rubber stopper is deviate from by steel ball impact extruded, in described dress bulb inwall, the side that is positioned at the nearly pitching cylinder of described rubber soft rubber stopper, Ka Tai or the baffle ring that is fastened in described rubber soft rubber stopper end is installed.
A kind of separate stratum fracfturing ball-throwing apparatus of the present utility model, its reasonable in design is simple and direct, adopts Long-distance Control, has greatly improved the safety of operation.At the ball storehouse cylinder that fills tube design, traditional ball-throwing apparatus can be effectively solved and once the defect of a steel ball can only be projected, ball storehouse cylinder and ball seat below, cooperatively interact, and by the Action of Gravity Field of steel ball, can realize continuous pitching, convenient in operation, efficiency is higher, time saving and energy saving.
