This invention discloses a high-conductivity emulsion-type intelligent fracturing fluid for oil and gas field enhancement and its preparation method. This fracturing fluid aims to solve the technical problem of the contradiction between the proppant-carrying capacity and the post-colloidal conductivity of traditional fracturing fluids in deep wells under high temperature and high salinity environments. Its core lies in the introduction of a temperature- and salt-responsive zirconium-silicon hybrid nano-crosslinking agent and biomimetic surface-modified layered silicate nanosheets. In preparation, a water-in-oil base emulsion is first formed, followed by the sequential addition of the two modified compounds. The nano-crosslinking agent is prepared through silanization and polymer grafting processes, enabling intelligent activation and viscosity enhancement under formation conditions. The nanosheets are prepared through montmorillonite exfoliation and biomimetic dopamine coating modification, combining drag reduction and proppant surface modification functions. This fracturing fluid system achieves intelligent response with low friction during pumping, high proppant-carrying capacity in the formation, and the formation of high-conductivity channels after colloidal breakdown, making it particularly suitable for fracturing and stimulation of deep and unconventional reservoirs.

The invention relates to the technical field of engineering machinery, and particularly discloses a milling machine control method, a milling hydraulic system and a milling machine, the milling machine control method is implemented through the milling machine, and when the milling machine works through the milling machine control method, due to the fact that the displacement of a milling pump and the displacement of a milling motor can be both adjusted, the milling machine can work stably. S20, the displacement of the milling pump and / or the displacement of the milling motor are / is adjusted, so that the rotating speed V < actual > of the milling drum is equal to V < set >. S40, judging whether the real-time pressure value P < actual > in a milling hydraulic system of the milling machine is larger than the set allowable maximum pressure value P < set >, if yes, indicating that the working resistance of a milling drum is large, and executing S40, and setting P as the maximum pressure value borne by the milling hydraulic system: reducing the rotating speed of the milling drum or reducing the running speed of the milling machine, and if not, judging that the working resistance of the milling drum is large; therefore, the pressure P < actual > in the milling hydraulic system is reduced. According to the arrangement, the rotating speed of the milling drum and the rotating speed of the engine are respectively and independently controlled, the requirements of various working conditions are met, the construction energy consumption is reduced, and the construction efficiency is improved.
