Description

Novel diesel water pump unit

Technical Field

The utility model relates to an oil development fracturing unit field, in particular to novel diesel pump unit.

Background

In the process of exploiting the oil and gas field, the fracturing technology is one of important technical means for increasing storage and increasing production of the oil and gas field, and the fracturing operation is carried out on the oil and gas well, so that the permeability of an oil and gas layer can be enhanced, the flowing environment of oil and gas at the bottom of the well is improved, and the purpose of improving the yield of the oil and gas is achieved. In the fracturing operation process, the performance of the fracturing equipment directly determines the fracturing effect of an oil-gas well and the increase of the oil-gas yield. At present, fracturing equipment mainly comprises a fracturing pump truck, a sand mixer truck, an instrument truck, a high-pressure manifold and related fracturing auxiliary equipment. The diesel oil water pump unit is a fracturing auxiliary device and mainly provides a power lifting device for water for fracturing operation of oil and gas fields.

At present, a diesel pump unit commonly used in domestic fracturing operation sites mainly comprises a diesel engine, a coupler, a middle-open double-suction centrifugal pump, a manifold and other parts. However, the diesel water pump unit commonly used in the fracturing site in China has a single water flow direction and cannot realize reverse water delivery. Before the diesel pump unit starts the pump at every time, complex operations such as pump priming and the like of the water pump are required to be carried out in advance, the diesel pump unit is long in starting time during fracturing operation, and response is not timely. After the fracturing operation is finished, the residual water in the water conveying pipeline and the residual water in the environment-friendly water storage tank can be only treated by a conventional suction and discharge method, so that time and labor are wasted, the environmental pollution of an operation site is easily caused, and the environment is not favorable for environmental protection.

Disclosure of Invention

The utility model aims to solve the technical problem that it still need carry out the pump priming in advance to the water pump and in well site operation completion back environmental protection cistern and conduit surplus water can only handle the problem of wasting time and energy not environmental protection with conventional suction drainage method before overcoming the current diesel water pump unit that exists in the background art at every turn and opening the pump, and provide a novel diesel water pump unit, this novel diesel water pump unit, can be with in the outlet conduit and the environmental protection cistern in deposit a large amount of surplus water discharge smoothly, reduce environmental pollution, need not the jar pump, time saving and labor saving, guarantee the safety in production.

The utility model provides a its problem accessible reach as follows technical scheme: the novel diesel water pump unit comprises a pump driver, wherein the pump driver is connected with a rotary self-sucking pump through a coupling; the rotary self-priming pump is connected with a water inlet manifold and a water outlet manifold, and the water outlet manifold is connected with an environment-friendly reservoir through two water conveying pipelines; the water inlet manifold is connected with the first-stage reservoir.

Compared with the above background art, the utility model can have following beneficial effect: this novel diesel water pump unit, simple structure, convenient operation, operation safe and reliable has adopted unique diesel water pump unit structural design, has not only solved the diesel water pump unit that internal fracturing operation is commonly used and has supplied water the single drawback of direction when supplying water, makes the fracturing operation accomplish the back, can convenient and fast's processing fall out the surplus water problem in the environmental protection cistern and the conduit, can also save loaded down with trivial details pump filling step for the user, has improved fracturing operating efficiency greatly. Has better practical application value.
