Directional drilling special foundation engineering mud soil: mud is the "blood" of directional drilling, drilling and underground excavation, while bentonite is the "skeleton" of water-based mud.
In the horizontal directional drilling (HDD) construction, the mud has the important functions of cooling, lubrication, carrying drilling chips and stabilizing the hole wall.In HDD construction, especially HDD construction in complex strata, mud is the key to the success of the project.For HDD mud, the gel strength is one of its important properties, the greater the gel strength, the stronger its suspension drilling chip capacity.In addition, the mud shall have good leakage resistance characteristics.Good mud can form a dense mud skin on the hole wall, thus preventing the mud from leaking to the formation.The product slurry speed fast, small filter loss, good rheology, with excellent wall performance, can effectively discharge hole suspension drill, reduce the mud circulation pressure, reduce the risk of loose strata is fracturing and ground uplift, at the same time, can prevent the viscosity underlying water dispersion, expansion caused by hole shrinkage, drill mud bag and other bad phenomenon.In addition, the good lubrication performance of the product greatly reduces the drag resistance, reduce the risk of user construction.
This product is widely used in directional drilling engineering, pipe jacking engineering, rotary excavation pile foundation engineering, underground continuous wall engineering, drilling engineering, shield engineering, oilfield drilling engineering, etc.
1. The product is compound mud material, and the construction site needs any other mud additives to meet the construction needs of the general stratum. The mud mixing time is 5-20 minutes.
2, The mud has good touch, improve the mud support suspension, carrying capacity, mix good mud in pumping flow, presents a good flow state, pumping resistance, when stop pumping, presents a good gel (solid) state, suspended the debris in the hole, ensure that the bottom does not deposit, and the debris out of the hole.
3. Mud has good particle grading, which can quickly form a stable and dense mud cake on the excavation surface of "sand soil" with high water content and high permeability, improve the sealing of "sand soil", reduce its permeability, and prevent the collapse of the excavation surface.
4. The "expansion agent" in the mud enters the "sand soil" under the liquid pressure, and relatively reduces the water content of the soil layer around the excavation surface to control the quicksand, making the "sand soil" has plastic characteristics, which will provide smooth and controllable support pressure and improve the stability of the hole wall.
5. The PH value of mud is greater than 8.5, the use is less than ordinary bentonite mud materials, low labor intensity, low pollution to groundwater and surrounding areas, and good working environment.
