Description
Technical Field

Background
The domestic vertical well fracturing has the objective limitations of small fracturing fluid amount and small field in the construction process, and a jet fluid distribution technology is mainly used, namely, a thickening agent is mixed with clean water by utilizing the principle that negative pressure can be generated when water passes through a pipeline at high speed. The implementation method is that N water tanks are prepared and filled with clear water. The jet flow equipment sucks clean water in the first tank and then discharges the clean water to the tank to form circulation. In the circulating process, a thickening agent (powder) and various liquid additives are sequentially sucked by utilizing the principle that water passes through a pipeline at a high speed to generate negative pressure, and after the medicament is sucked, the tank is fully circulated to the tank, the liquid in the tank is uniformly mixed, so that the preparation of the fracturing fluid in the first tank is completed. And repeating the above operations to complete the preparation of the N tanks of fracturing fluid.
Such a solution preparation process has a number of drawbacks:
in the process aspect, the fish eye type powder dough can not be completely eliminated, and the concentration of the base liquid is reduced because the thickening agent can not be completely swelled; on equipment, a water-powder mixer is easy to block materials, and once the water-powder mixer is blocked, the water-powder mixer needs to be stopped for cleaning; the labor intensity of workers is high, other liquid additives are sequentially sucked after the thickening agent is fully swelled, and the final base liquid can be obtained through full circulation, so that the process is long in time consumption and low in construction aging.

With the rapid development of the petroleum industry, fracturing construction is an effective measure for increasing the yield of oil fields. At present, the workload of fracturing construction in China is increased year by year.

However, after the fracturing flow-back fluid is treated, a large amount of bubbles are generated in the secondary fluid preparation process of the fracturing fluid by adopting a conventional jet flow mode, and finally, the preparation of the fracturing fluid cannot be completed. If the defoaming agent is adopted to solve the foaming problem, the cost of preparing the fracturing fluid by the flowback fluid is increased virtually, the formula of the fracturing fluid in each block is greatly different, and a single defoaming agent cannot be applied to the fracturing flowback fluid of all systems.
