摘要： A continuous static mixing apparatus includes mixing disks. Each of the mixing disks has a set of symmetrically distributed nozzles therein that accelerate the flow and that create a mixing turbulence in the flow. Typically, the mixing apparatus combines the outlet flows of the mixing disks to provide a collision therebetween and, thus, increased turbulence and mixing. Communication passageways connect the material supplies to the mixing apparatus and direct the materials through the mixing disk. The materials may be combined either upstream or downstream of the mixing disks. An eductor may be used to combine the materials upstream of the mixing disks.

Each jet pump assembly (26) has an outer housing (28) secured to the bit body (14) and receiving any elongate nozzle member (46) therein in concentric relation to form an annular chamber (48) therein. A flow restriction (38) is mounted within the outer housing (28) above the nozzle member (46). The elongate nozzle member (46) has a lower nozzle port (50) and an opposed upper nozzle port (52). Drilling fluid from the central bore (20) is directed to the nozzle member (46) where the drilling fluid is divided into two streams, one stream for flow through lower nozzle port (50) against the formation and the outer stream for flow through the upper nozzle port (52) and flow restriction (38) to create a low pressure area or suction in an annular chamber (48). A low pressure cross sectional area is formed at the bottom of the bore hole (B, FIG. 4) and drilling fluid with entrained formation cuttings is drawn upwardly through the annular chamber (48) and the flow restriction (38).

摘要： A liquid cleaning system for liquid that is substantially continuously circulated and which becomes contaminated with solid particulate and debris during circulation. The liquid cleaning system, which is particularly advantageous to cleaning liquid that is circulated within a petroleum well bore during completion and workover activities, incorporates a vibratory screen separator for accomplishing preliminary separation of large particulate and debris from the contaminated liquid and which also incorporates a filtration bank having a plurality of filters that are each interconnected with inlet discharge and drain headers. Filter bank incorporates a valving system having the capability of accomplishing backflushing by circulating clean fluid in reverse manner through selected ones of the filters to remove collected solid particulate therefrom and transport the removed particulate to the drain header. The drain header is interconnected with a centrifugal solids separation system that separates a majority of the solid particulate material from the backflushing fluid and transports the backflushing fluid back through the filter bank for cleaning thereof. The filter bank is designed for selective backflushing of individual filters thereof while at the same time maintaining continuous filtering activities by means of other filters in order that the liquid circulation system may function in continuous manner without necessitating any downtime for restoration of the filtration system.

摘要： An improved fluid mixing nozzle and method, in which a first fluid flows therefrom to mix with a second fluid external the nozzle, for inducing vortex creation and chaotic turbulent flow. The nozzle has a body with a cavity extending therethrough from the inlet end to the outlet end. The cross sectional area of the inlet orifice of the nozzle is greater than its outlet orifice cross sectional area. The outlet orifice cross section area shape has a substantially circular central portion and at least one (but typically more than one) protrusion extending from the perimeter of the central portion. Generally, the protrusions are smaller in cross sectional area than the central portion, are equally spaced about the central portion perimeter, and have a length to width ratio from 1 to 2. Functionally applying the above described nozzle is a method of improved mixing, of creating chaotic turbulent flow, and of inducing vortex creation.

摘要： An apparatus for cleansing a stream of drilling fluid fouled drill cuttings having a housing divided into a plurality of compartments each designed to retain cleansing fluid. A spinning force is imparted into the incoming fouled drill cuttings in an inlet chamber wherein cleansing fluid is intimately mixed with the fouled drill cuttings. A decanting chamber removes liberated drilling fluid from the cuttings and disposes of such drilling fluid from the apparatus via a drain trough assembly. The underflow from the decanter is passed through a solids concentrating assembly wherein the coarse solids are deposited in a concentrating assembly bottoms chamber wherein the settled drill cuttings are removed from the apparatus. The overhead stream from the solids concentrating assembly is directed to a second decanter for removal of any remaining drilling fluid and fine drill cuttings entrained therein from the apparatus via the drain trough assembly. The remaining fluid in the concentrating assembly bottoms chamber is recirculated to the second decanting chamber and the inlet chamber.
