What is Downhole Pressure?
Bottom hole pressure refers to the total pressure exerted on the bottom of the well by various pressures on the ground and in the well. The bottom hole pressure is different under different operating conditions. In a static state, bottom hole pressure = hydrostatic pressure. In a static state, the bottom hole pressure is mainly composed of the hydrostatic pressure of the drilling fluid, which is mainly affected by the density of the drilling fluid and the height of the liquid column in the well.
For wells with active oil and gas, it is necessary to pay attention to the diffusion effect of the gas in the formation on the density of the fluid in the well when the fluid in the well is static for a long time, which may eventually affect the bottom hole pressure. In addition, in a static state, the liquid level at the wellhead should be monitored to prevent the height of the liquid column from decreasing and affecting the bottom hole pressure.
