Rapid refueling and purifying equipment for petroleum drilling and fracturing

Abstract

The invention discloses rapid refueling and purifying equipment for petroleum drilling and fracturing. The purifying equipment comprises a purifying oil inlet end pipeline, a purifying tank and a purifying oil outlet end pipeline, wherein the purifying oil inlet end pipeline is communicated with a liquid inlet end of the purifying tank, the purifying oil outlet end pipeline is communicated with aliquid outlet end of the purifying tank, and valves are arranged on the purifying oil inlet end pipeline and the purifying oil outlet end pipeline. The rapid refueling and purifying equipment has thebeneficial effects that by completely utilizing a physical separation manner, mediums are not influenced and changed at all; the filtering efficiency is greatly improved, the handling capacity is increased, the service life is prolonged, and the coalescence speed and the two-phase separation speed are relatively high; a filter element in the design is relatively convenient mounted, easy to operateand low in labor intensity; and therefore, clean diesel can be provided, and rapid refueling can be realized.

Description

technical field [0001] The invention relates to the technical field of petroleum extraction, in particular to rapid refueling and purification equipment for petroleum drilling and fracturing. Background technique [0002] The acid treatment process of squeezing the formation under the pressure enough to open the formation to form fractures or open the original formation fractures is called fracturing acidization. It can be divided into front fluid acid fracturing and common acid fracturing (or general acid fracturing). Fracturing and acidizing are mainly used to plug oil and gas wells in deep or low permeability areas. Fracturing and acidizing in which the acid injection pressure is higher than the fracture pressure of the oil (gas) layer is commonly called acid fracturing. Acidizing hydraulic pressure is a widely used measure to increase production and injection in limestone reservoirs at home and abroad. Now it has begun to become an important means of well completion, ...

AI Technical Summary

Problems solved by technology

[0003] In oil drilling and fracturing sites, the supporting fracturing equipment is high fuel consumption equipment, especially the fracturing pump truck, which needs to be refueled about two to five times during the eight-hour work, while the existing refueling process at the general well site is that the oil tanker directly Refueling to the oil receiving equipment, or the oil tank truck to the pressurized oil pump pipeline and then transported to the oil receiving equipment, this process can only refuel a single equipment

In general, at least 4 or more fracturing pump trucks are equipped at the same time at the fracturing site. Refueling according to this process will not only waste time, but also cause hidden dangers to the HSE of the well site.

However, due to the long-term failure to clean and transfer various crude oils in oil tank trucks, the diesel oil contains various impurities, water and other pollutants, which will cause the filter system of oil drilling equipment to be blocked or the fuel filter to be damaged. In severe cases, the combustion system of the engine cannot normal work

Therefore in the prior art there is not a kind of equipment that can provide clean diesel oil and can realize fast refueling
