Background
Borehole flushing fluids are commonly referred to as "blood" in drilling projects, and their importance is self evident. In recent years, great development has been made on the wall protection technology of flushing liquid and the leakage prevention and stoppage technology, but the wall protection technology under the conditions of strong breakage and continuous leakage of the stratum is difficult to break through all the time. For example, when drilling construction is carried out in a whole survey area of a rhodanu mine field in Sichuan province, the formations to be drilled are mainly carbonaceous slates and limestone which are extremely broken, and limestone erosion holes and longitudinal cracks are extremely developed, so that unstable formations and lost formations frequently and alternately appear. Therefore, during drilling construction, once the leaked stratum rock is drilled and uncovered, the conventional flushing liquid leaks out immediately due to formation crack development and higher density of the flushing liquid, so that the anti-collapse capability of the upper carbon plate rock stratum is difficult to exert; in order to ensure the stability of the pore wall of the carbon plate rock stratum, a collapse-preventing and leakage-preventing drilling flushing fluid while drilling needs to be researched;
the foam generator fully mixes gas and drilling flushing fluid, reduces the density of the drilling flushing fluid, reduces the pressure of a liquid column and increases the leakage resistance on the basis of ensuring the performance of slurry so as to achieve the purposes of preventing collapse and leakage. The existing foam generators have various styles, such as jet flow type, concentric tube type, spiral tube type, turbine type and the like. A jet foam generator as in the first: the two-phase gas-liquid foam foaming device comprises two sections of cavities with different diameters, wherein a gas-liquid two-phase fluid enters a large-diameter cavity through a small-diameter cavity at a high speed, and the pressure is rapidly diffused to the periphery, so that the gas-liquid two-phase fluid is dispersed and mixed to form foam. A second concentric tube foam generator: the gas-liquid two-phase fluid is jetted to the main pipe in a jet mode through the small holes at high speed, and is quickly dispersed and mixed to form uniform foam. The spiral pipe type foam generator and the turbine type foam generator are arranged in the pipe body, and the flow direction of fluid and the flow state of the fluid are constantly changed by arranging a spiral diversion trench or a spiral flow clapboard in the pipe body, so that strong turbulent flow and spiral flow are formed, and the gas phase and the liquid phase are uniformly mixed;
