Maintenance considerations for oil drilling machinery and equipment
Second, regularly check the equipment seal, once the equipment seal oil leakage, to timely shutdown, and the oil leakage will be sealed; in addition, to regularly check the connection of each connection firmware, such as loose, to timely reinforcement.
What drilling tools are available and the function of the drilling tools
Shock Absorber A tool that accumulates elastic energy to produce shock when the drill column is elongated elastically under tension, which can be used to deal with stuck drill accidents and facilitate safe drilling.
What are the two current drilling methods?
Rotary drilling is the current common spa drilling method, and there are two types of rotary drilling and downhole power drilling according to different power transfer methods. 1、Rotary drilling. A rotary disc is installed at the wellhead of the drilling platform, with a square hole in the center of the rotary disc, through which the square drill rod at the upper end of the drill column passes, and the drill column and drill bit are connected under the square drill rod. When the power machine drives the turntable, it drives the drilling column and bit to rotate together, breaking the rock, deepening the borehole as the drilling column lengthens, and returning the rock chips to the surface with the recycle mud. 2、Downhole power drilling. Downhole power drilling tools are used to drive the drill bit to break the rock. The characteristic is that the drill column does not rotate while drilling, which is suitable for drilling directional wells with low wear and long service life. There are turbine drilling, screw drilling and electric drilling tools. The first two are driven by high-pressure mud, while the latter one is driven by electricity. turbine drilling was first used in the Soviet Union in the early 1930s, and turbine drilling and screw drilling have been used in China since the 1950s, mainly for drilling directional wells. Electric drilling requires special drilling columns with cables and has not been used in large quantities.
Understand the geological structure before drilling
Hot Springs drilling is the process of drilling a cylindrical borehole with a certain depth into the ground using mechanical equipment. Before drilling a well, we must first understand the geology of the area to be drilled, such as the strength, hardness and drillability of the rock, in order to arrange the drilling operation in a scientific and reasonable manner.
Domestic oil instruments adhere to the "go out" active world
Oil logging instruments continue to develop in the direction of high integration, high reliability, high timeliness, imaging logging systems, drilling logging systems and other logging instrument development has become the focus of major logging instrument production developers, but also represents the future development direction of oil logging instruments.
