摘要： The method for releasing the stuck pipe of the present invention uses a combination of components which oxidize the mud cake and generated gas bubbles to create an upward buoyancy for the oxidized mud cake. The spotting method of the present invention comprises adding to the borehole in the region of the stuck pipe: 1) an oxidizer which oxidizes the mud cake; and 2) at least one component which reacts in the borehole to generate a gas. Optionally, but preferably, the spotting method further uses a lubricant which is added to the borehole in the region of the stuck pipe. The lubricant acts to lubricate the oxidized parts of the mud cake. Also disclosed is a spotting fluid system including 1) an oxidizer which oxidizes the mud cake, 2) at least one component which reacts in the borehole to generate a gas, and, optionally a lubricant which acts to lubricate the oxidized parts of the mud cake.

摘要： Apparatus and methods are disclosed for drilling a well. A separator sub includes a cyclone separator which separates a stream of drilling mud into a less dense first portion and more dense second portion. The stream of drilling mud flows downward in an annular stream around the cyclone separator and then flows into a lower end of the cyclone separator. The less dense first portion of the stream of drilling mud is directed from the cyclone separator downward to a drill bit so that the drilling mud adjacent the drill bit has a density less than an initial density of the stream of drilling mud. The more dense second portion of the stream of drilling mud is directed upward from the cyclone separator and is ejected into a well annulus with an upward component of velocity and thereby reduces a hydrostatic drilling mud pressure adjacent the drill bit.

摘要： In one embodiment, the cyclone separator includes an adjustable sidearm conduit which selectively receives different strata of particles passing through the radially outer sectors of the cylindrical region defined within the cyclone body. The cyclone separator may further include a traveling cone valve to restrict the size of the lower outlet. The vortex finder of the cyclone may include a vortex side port to extract the heavier particles entrained in the forced vortex received by the intake of the vortex finder. An inner vortex finder tube is further disposed in the passage through the vortex finder. In another embodiment, the traveling cone is replaced by a lower outlet head spaced from the lower outlet and the lower portion of the housing defining the apex of the frustoconical region. A control system may be combined with the cyclone separator to analyze the particles extracted from the various outlets from the cyclone and effect a change of the controllable features of the cyclone such as the position of the sidearm conduit and affecting the size of the lower outlet. A method for separating particles includes establishing a free vortex and a forced vortex within the cyclone and selectively extracting strata of particles traveling in the radially outer sectors in the cylindrical region of the cyclone body.

摘要： A drilling sub is provided in a drill string above a drill bit. The drilling sub includes a nozzle oriented to eject drilling fluid from said drill string into an annulus between the drill string and a well bore hole at an elevation above the drill bit with a horizontal velocity component tangential to said annulus to thereby impart a swirling motion to drilling fluid in the annulus. This creates a vortex extending down to the drill bit to enhance the cleaning of cuttings from the bore hole and to reduce a pressure differential thereby increasing a penetration rate of the drill bit.

摘要： A downhole separator sub for separating drilling mud into a more dense portion and a less dense portion. The apparatus includes a barrel having a central opening therethrough and a cyclone separator cartridge positioned in the central opening. The barrel is attachable to the drill string and the drill bit. The cyclone separator cartridge includes an upper insert, an intermediate cyclone separator housing and a lower insert. An annular flow passage is defined between the cyclone separator housing and an inner surface of the barrel. The upper insert includes an inlet passage providing communication between an upper portion of the barrel central opening and the annular flow passage. The lower insert includes a cyclone inlet providing communication between the annular flow passage and a cyclone chamber in the cyclone separator housing. A removable vortex finder tube is positioned in the cyclone separator housing and has an outlet hole through which less dense fluid is discharged into a lower portion of the barrel central opening. The upper insert also includes an underflow passage in communication with the cyclone chamber. The underflow passage has an outlet positioned adjacent transverse holes in the barrel through which more dense fluid is discharged from the apparatus into a well annulus. Alternate embodiments include deflectors adjacent the transverse holes in the barrel to prevent direct impingement of fluid on a wall of the well annulus and a sleeve interconnecting the upper and lower inserts to separate the annular flow passage from the remainder of the barrel central opening.

摘要： A fluid agitating apparatus is disposed in a vessel containing a body of fluid to be agitated. The fluid agitating apparatus includes a housing having an inlet at an open lower end thereof, and an outlet at an open upper end thereof, with a flow passage disposed through the housing communicating the inlet and the outlet. The flow passage is preferably circular in cross-section and has a minimum diameter at a throat thereof. The diameter of the flow passage increases continuously from the throat toward both the inlet and the outlet. A vertically upward directed nozzle is located in the flow passage below the throat for inducing flow of fluid from the body of fluid in which the housing is submerged into the inlet and upward through the flow passage. A tangentially directed nozzle is disposed in the flow passage above the throat for inducing a swirling flow in the fluid flowing upward through the flow passage. This creates a swirling vortex type flow exiting the outlet of the housing which provides agitation of the body of fluid in which the apparatus is submerged. Covers are provided in the corners of the vessel to prevent deposition of sediment at those corners. Additional nozzles extend through a wall of the vessel near the bottom thereof for agitating a lower portion of the body of fluid adjacent the bottom of the vessel.
