Determination method for drilling fluid density in managed pressure drilling

The invention provides a determination method for a drilling fluid density in managed pressure drilling. The determination method comprises the following steps: acquiring a formation pressure Pp, a collapse pressure Pb, a cracking pressure Pf, an allowable value Sb of a suction pressure, an allowable value Sg of a surge pressure, an allowable value Sk of a well kick adjusting pressure, a formationfracture safe added value Sf, a pressure difference allowable value deltaPn, a wellhead back pressure P and circular pressure consumption deltaP; determining the minimum density value rho2min of a drilling fluid in a stationary state, determining the maximum density value rho2max of the drilling fluid in the stationary state and determining the maximum density value rho4max of the drilling fluidin a circulating state; and determining the range of the density rho of the drilling fluid: rho is greater than or equal to Max(rho2min, rho4min) but smaller than or equal to (rho2max, rho4max). The determination method can determine the value range of density of the drilling fluid in managed pressure drilling effectively, so that the operating time of managed pressure drilling site operation is shortened, the operating cost is reduced, a well wall is maintained stable, various drilling accidents and complex conditions are avoided, and a reservoir can be also prevented from being polluted.

Triangular alloy tool bit

InactiveCN106270665AImproved cutting efficiencyshorten working time
The invention relates to a triangular alloy tool bit, and aims to mainly solve the technical problems that an existing alloy tool bit is nearly all linear, is lower in cutting operation benefit and the like. The triangular alloy tool bit is characterized by comprising a first cutting edge, a second cutting edge and a third cutting edge which are circularly and uniformly distributed and arrayed to form a whole, wherein the inner sides of the first cutting edge, the second cutting edge and the third cutting edge are higher than the outer sides of the first cutting edge, the second cutting edge and the third cutting edge, so that the upper ends of the first cutting edge, the second cutting edge and the third cutting edge are respectively inclined. The triangular alloy tool bit disclosed by the invention has the beneficial effects that by arranging the first cutting edge, the second cutting edge and the third cutting edge, when a drill bit operates, an electric drill drives the drill bit to rotate by one circle, and then cutting output of one cutting edge can be correspondingly increased compared with an existing drill bit, so that cutting benefits of the drill bit can be remarkably improved by one third, the operation time is correspondingly shortened by using the triangular alloy tool bit under the same workload; as the operation time is shortened, the service life of the drill bit can be effectively prolonged.
