Abstract
The invention discloses a pressure test device of a hydraulic cementing tool and a working method, and belongs to the pressure test technology of petroleum tool products. The pressure test device of the hydraulic cementing tool and the working method overcome the defects of other technologies. The pressure test device of the hydraulic cementing tool is composed of a hydraulic cylinder, a pressure test pipeline, a supporting plate, threaded rods, an upper plate, the cementing tool, sealing parts, a lower plate and nuts in a connected mode, wherein the hydraulic cylinder penetrates through the supporting plate to be connected with the upper plate, the pressure test pipeline penetrates through the supporting plate, the bottom end of the pressure test pipeline is connected to the upper plate, the supporting plate is installed at the upper ends of the threaded rods, the lower plate is installed at the lower ends of the threaded rods, and is fastened through the nuts, the sealing parts are inlaid into grooves of the upper plate and grooves of the lower plate, and the cementing tool is arranged on the sealing parts.
Description
Technical field: the present invention relates to a kind of product pressure test technology of petroleum tool class, especially fluid pressure type cementing tool pressure testing device and method of work.
Background technology: in normal pressure testing operation, because the specification of cementing tool product is a lot of and connected mode is various, often need to process all kinds of action pressure-testing joints and be mostly and be threaded, the kind being simultaneously threaded needs and the screw thread of product mates, the action pressure-testing joint of the different screw threads of specification of the same race like this has again a variety of, needs manually to screw simultaneously, and this kind of mode is not suitable for pressure testing in batches, service time of a specified duration just need to again process action pressure-testing joint, waste time and energy.
Summary of the invention: the object of this invention is to provide fluid pressure type cementing tool pressure testing device and method of work that a kind of operating efficiency is high, it has overcome the shortcoming that other technology exists, the object of the present invention is achieved like this, it is to be formed by connecting by hydraulic cylinder, pressure testing pipeline, support plate, screw rod, upper plate, cementing tool, seal, lower plate, nut, hydraulic cylinder is connected with upper plate through support plate, pressure testing pipeline is through support plate, and its bottom is connected on upper plate; Support plate is arranged on the upper end of screw rod, and lower plate is arranged on the lower end of screw rod, and has fastening nuts; In the groove of upper plate and lower plate, inlaying seal; Cementing tool is positioned on seal.
Method of work of the present invention is: this device is connected fastening by screw rod and nut realization, cementing tool is placed in pressure testing device, utilize the seal that upper plate and lower plate are inlayed to realize metal sealing to the upper and lower end face of cementing tool, hydraulic cylinder thrust output, cementing tool is fixed in pressure testing device, the water that extracts water tank by test pump is transported in cementing tool by pressure testing pipeline, realizes pressure testing operation process.Whole operation process is without manually cementing tool manually being screwed.
The invention has the beneficial effects as follows, 1. utilized hydraulic principle realization handling pressure testing product fast, the set-up time is short, and frequency of usage is high, only needs a people just can to operate by complete independently, and work efficiency is high; Simple in structure, reliable, safety coefficient is high; 3. by adjusting spiro rod length, can increase the scope of application of pressure testing product, the usable range of pressure testing device can cover all specifications of API standard cementing tool, and utilization factor promotes greatly.4. adopt metal sealing, realize the harmless pressure testing operation to product; 5, can save to greatest extent the pressure testing activity duration, greatly reduce artificial operation intensity.
