Ensuring that the drilling rods do not distort is a crucial part of the drilling process, which directly affects the efficiency of drilling and the quality of hole formation. The following are some common measures:
Pre-drilling preparation Drilling Tools Inspection. Drilling tools such as bits, rods and joints should be inspected regularly to ensure that there are no cracks, wear and other defects. The joints of each component should be tight and free from looseness. Borehole trajectory design. Reasonably design the borehole trajectory according to the stratigraphic conditions and construction requirements to avoid drilling into complicated strata. Drilling fluid preparation. The drilling fluid should have good rock-carrying capacity and suspension performance to ensure that the drill cuttings are discharged out of the well in time and prevent the borehole from shrinking.
Drilling Process Drilling pressure control. Excessive drilling pressure will easily lead to the deflection of drilling tools, while too little will slow down the drilling speed. The drilling pressure should be reasonably controlled according to the stratigraphic conditions. Speed control. Too high a speed may cause the drill bit to jump, while too low a speed may slow down the drilling speed. Choose the appropriate speed according to the type of drill bit and the hardness of the formation.
Control of drilling fluid parameters. Drilling fluid density, viscosity, water loss and other parameters should be adjusted according to the formation conditions to ensure the stability of the borehole. Timely handling of borehole complications. Timely measures should be taken to avoid further deformation of the borehole in case of borehole collapse or stuck drilling. Regular measurement of borehole trajectory. Regularly measure the trajectory of the borehole with measuring instruments to detect and correct the deviation in time.
Drilling Tool Selection and Maintenance Drill bit selection. Select the appropriate type of drill bit according to the hardness of the formation, drilling depth and other factors. Replace worn bits regularly. Drill pipe maintenance. Regularly check the curvature of the drill pipe and replace the badly bent drill pipe in time. Ensure the sealing of drill pipe joints.
Commonly used methods to prevent drill pipe distortion Mechanical directional drilling: Use mechanical devices to actively control the deflection direction of the drilling tools. Drill Follow Measurement: Real-time monitoring of the borehole trajectory by the drill follow measurement instrument to adjust the drilling parameters in time. Directional Drilling Fluid: Directional drilling fluid is used to control the flow direction of drill cuttings, which in turn affects the deflection direction of the drill bit.
