Description

Deep pumps are known with a forced opening pressure clan. However, in such machines, when pipeless deep-pumping operation, as well as in the joint operation of two horizons, the harmful influence of nodpacker gas takes place.

In the described pump these deficiencies are eliminated by the release of gas from under the pump plunger into the lifting pipes. For this purpose, the pump plunger is provided with an additional special sliding valve.

FIG. 1 shows a deep pump in longitudinal section; on fng. 2 is the same in cross section; in fig. 3-part of the pump in longitudinal section; in fig. 4-schematic diagram of the installation of a deep pump in the well with pipe-less operation mode, n in FIG. 5 shows the pumping unit's borehole layout for the joint operation of two horizons.

The sliding valve is a sleeve /, worn on the nozzle 2, screwed into the lower part of the pump plunger 3. The sleeve surfaces of the sleeve / and nozzle 2 are carefully machined. Slide n1, the valve moves with the ram. Forced sleeve / bushings are achieved by installing special spring-loaded four fixed rings 4. By their friction against the inner walls of the pump bushings y, the initial moments of changing the direction of the plunger's stroke somewhat delay the movement of the bushings. The movement of the sleeve /, the plunger itself is limited by the lower end of the plunger and the upper TopHOBoii by the surface of the valve cage 5. When the plunger moves down, the sliding sleeve abuts the lower end of the plunger and the npii end-in 1;

On the lower part of the pipe 2, an injection pump is installed. Stage 6. By forcing the sliding valve opening} 1a, the gas is released from under the valve to the lifting points and the valve: 0; The release of gas from under the plunger is accompanied by: a. Displacing 1 space occupied by gas and liquid entering

When using the described (lh) pump above d; 1st operation without pipes (Fig. 4) gas,) .5.1.1 reservoir,: 1spect for the presence of a jack), the pump is passed through the pump, the water supply is installed.

When a pump is used for jointly pumping two horizons (Fig. 5), it is installed under the packer to operate the lower horizon, and for the operation of the upper horizon a deep pass with a conventional ball valve is installed (not forced). Here, just as with non-rude operation, the zodobod pump is pumped through the packer-1 gas node, which provides the Elsp water pump with no special gas; no gas.
