Detailed Description
Various features of the invention are further described below in connection with the accompanying drawings and the examples.
The rock debris separating device can separate rock debris from drilling fluid for further research. As shown in fig. 1, a cuttings separation apparatus 100 (shown as 100 in the figure) in one embodiment of the present invention includes a feed port 107 for introducing a drilling mud containing cuttings, which may be provided at any location, or of any shape and configuration, into a solid-liquid separation unit 101 for separation, the solid-liquid separation unit 101 including a tubular screen 111 and a solids discharge mechanism 112 passing through and pivotable relative to the tubular screen. Wherein the tubular screen 111 has a slurry inlet 111a for introducing slurry and a solids outlet 111b for allowing separated solids to leave the solid-liquid separation unit 101.
FIGS. 2a-2b are schematic diagrams of solid-liquid separation units. As shown in fig. 2a, 2b, the tubular screen 111 may be cylindrical with both end faces 1112, 1113 closed, and a side wall 1110 provided with an inner wall filtrate screen 1110a and open with a slurry inlet 111a and a solids outlet 111b. The size of the cuttings to be screened can be selected according to the filter screen, for example, different meshes can be set according to the sizes of the siltstone, the mudstone and the carbonate drilled by the PDC drill bit, for example, 80 meshes, 100 meshes and the like, and ribs 120 can be added on the inner side or the outer side of the screen to increase the strength of the screen on the side wall. The ribs may be divided into longitudinal ribs 120a and circumferential ribs 120b, and the longitudinal ribs may be divided into main longitudinal ribs and auxiliary longitudinal ribs having different thicknesses and lengths. The main longitudinal rib may extend in the length direction of the entire sidewall, and the auxiliary longitudinal rib may extend in the length direction of the entire sidewall.
The solids discharge mechanism 112 may be coaxially disposed through the interior space of the tubular screen 111. For example, the solid matter discharge mechanism 112 may be fitted into shaft holes on both end surfaces of the tubular screen by means of a mandrel 112a through a boss, a bearing, or the like, so that the solid matter discharge mechanism 112 may pivot with respect to the tubular screen. The mandrel 112a may be driven to rotate by a motor drive, or directly by a motor drive, through a gearbox coupled to a motor, or a chain coupled to a motor, or by a hydraulic motor driving a tubular screen pivot, for example, to rotate the solids discharge mechanism 112.
The solids discharge mechanism 112 may include a long shaft portion fixedly connected to the spindle 112a and a carrying portion 112b spirally extending along the long shaft portion. Of course, the long axis may not be provided, and the carrying portion 112b may be directly attached to the mandrel 112a as shown in fig. 2a. The attachment may be removable to facilitate replacement of the carrying portion, although non-removable fixed connections may be used. The helical extension may be of any pitch.
The carrying portion 112b is used to deliver solid rock cuttings from one end of the long shaft portion or mandrel to the other. As shown in fig. 3a, the carrying portion 112b may be a continuously disposed structure 1120, for example, in the form of a belt; the non-continuous structure 1121 shown in fig. 3b may also be, for example, in the form of a comb or brush having a fixed or varying pitch. The carrying portion may also be formed of a flexible material so that the compressive forces exerted on the cuttings during their transport are reduced, preventing the cuttings from being damaged and maintaining the cuttings in their original size and form. For example, the continuous carrying portion may be provided as a continuous elastic band, which may be made of natural rubber, synthetic rubber, or silicone, etc., which may have a larger dimension near the long axis portion and a smaller dimension away from the long axis portion. Instead of an elastic band, a comb or brush having a certain strength and density may be used, for example, a brush, a rubber comb, or the like may be used. The brushes or rubber combs may be arranged in parallel in multiple groups to increase strength.
The carrying portion 112b extending along the long shaft portion or the mandrel may drive the slurry entering the inner space of the tubular screen to move from the slurry inlet 111a to the solid outlet 111b, during which the drilling fluid is penetrated out through the tubular screen and solid matter such as cuttings is sent to the solid outlet 111b.
As mentioned above, in further embodiments, the carrying portion may also extend directly helically and be secured to the mandrel without the need for a long shaft portion.
The outer edge of the carrying portion 112b is generally positioned against the inner wall 1110a of the tubular screen. For example, if a continuous structure 1120, the top of the carrying portion opposite the tubular screen may have a cleaning portion 1120a, which may be a hard material, such as a scraper blade made of metal, plastic, or a brush or comb made of a soft material, such as a brush, plastic brush, rubber comb, or the like, which may act to clean the inner wall 1110a of the tubular screen during the process of the carrying portion opposite the tubular screen. An example of this is given in fig. 4 a. Whereas if the carrying portion is a discontinuous structure 1121, such as comb-like or brush-like as described above, cleaning of the tubular screen inner wall 1110a may be accomplished, for example, as long as its length meets or exceeds the tubular screen. Of course, it is also possible that the comb-like or brush-like portions do not reach the inner wall of the tubular screen.
As shown in fig. 5a to 5c, the solid-liquid separation unit may be horizontally, obliquely or vertically disposed. The inclined arrangement may be more convenient for drilling fluid filtering out. In the embodiment shown in fig. 5b, the tubular screen is arranged at an angle of 30 degrees to the horizontal. It should be understood that other arbitrary angle arrangements are possible, such as 15 degrees, 45 degrees, 60 degrees or any other angle therebetween.
The tubular screen may also be arranged at an angle of 15-60 degrees to the horizontal, e.g. 30 degrees or the like, diagonally downwards. At this time, except along the arbitrary position of tubular screen axis, can also set up the feed inlet at an terminal surface of tubular screen, the mud that has the detritus moves along tubular screen under the action of gravity, at this moment, can set up the carrying part that extends along a dabber spiral to be to the higher direction delivery mud of horizontal position, hinder the flow of mud promptly to the time that makes mud in tubular screen becomes longer, does benefit to the leaching of drilling fluid.
The inclined arrangement of the carrying section in the tubular screen increases the load on the drive of the carrying section, but as the mud is lifted to a greater height, drilling fluid is more likely to pass through the screen of the tubular screen under the influence of gravity. The inclination angle of the tubular screen can be adjusted by an angle-adjustable supporting mechanism.
In further embodiments, the tubular screen may be configured to be pivoted relative to the carrying portion by a drive mechanism 106, such as a motor-driven acceleration-deceleration device, a chain drive, or directly by a motor or by a hydraulic motor. The rotation may be a continuous rotation or an intermittent rotation, which may be controlled by the control device 109. The solid-liquid separation device is continuously or indirectly rotated to change the upward movement of rock fragments, so that the blockage of the partial sieve wall can be avoided.
The drilling fluid separated from the mud falls directly or through a collecting structure such as a funnel into a liquid pan or sump of the base part of the cuttings separation apparatus 100, which may be provided with a drain through which the drilling fluid may be discharged from the cuttings separation apparatus for subsequent use after collection. The separated rock debris part is discharged from the solid outlet 111b to be used later under the driving of the carrying part.
Both the horizontally arranged cuttings separation apparatus and the vertically arranged cuttings separation apparatus shown in figures 5a and 5c may effect separation of cuttings from drilling fluid. For example, drilling fluid in mud in an upright cuttings separation apparatus may be forced out of the tubular screen under the urging of the carrying section. While a horizontally disposed cuttings separation apparatus need not push mud from a lower level to a higher level along the long axis as is the case with an inclined arrangement.
In other embodiments, such as the cuttings separation apparatus shown in figures 6a and 6b, reference numeral 200 is used in this example to distinguish the previous embodiments. In the present embodiment, the solid-liquid separation unit 201 may be provided with a vibration mechanism 203 as an auxiliary portion for enhancing the filtering effect on the slurry. The vibration mechanism 203 may include a vibration generating portion 2031, for example, a rotating cam structure, a buffer portion 2032, and a control portion 2033. The vibrating mechanism or the auxiliary part can be arranged at the middle upper part of the tubular sieve, and an adjustable vibrator can be adopted for assisting in solid-liquid separation, so that the separation efficiency is improved. Finally, the solid-liquid separation is realized continuously in all weather.
The material splitting section may carry a tubular screen, a shock absorbing support and an auxiliary section above the lowermost layer of the overall device. The material splitting section collects all of the separated liquid and outputs it through a conduit. And (3) enabling the separated solid matters to enter a discharge conveying mechanism through a tubular sieve, and finally outputting the device.
The ultrasonic vibration mechanism can be used for replacing the mechanical vibration mechanism, and converts high-frequency electric energy into mechanical energy through the ultrasonic vibration mechanism by means of a sound wave generator to drive the tubular screen to perform ultrasonic vibration so as to assist in filtering rock debris.
As shown in fig. 6b, the cushioning portion 2032 may be a spring cushioning bracket. Is installed between the solid-liquid separation unit 201 and the base 204. The solid-liquid separation unit 201 may be made to vibrate, or to translate or oscillate, or a combination thereof, for example in a direction substantially perpendicular to the long axis of the solid-liquid separation unit by providing the position and angle of the spring-damper support.
To prevent liquid splashing and to protect the device, a housing 208 is mounted in fig. 1. The housing may be constructed in a closed configuration to house the solid-liquid separation portion and the liquid recovery portion in a fully enclosed housing with an observation window and a maintenance door. An adjustable motor 206 and controller 209 are mounted at one end of the housing 208 to power the entire solids discharge device and to effect control of the device. The solid-liquid separation portion 201, the auxiliary portion 203, and the solid matter discharge mechanism are enclosed inside an enclosed housing 208.
In operation, drilling fluid and cuttings discharged from the wellhead flow through the channels into the mud pit and into the apparatus from the feed ports 107, 207 in fig. 1 or 6 a. After entering the device, the drilling fluid starts to separate through the tubular screen 101, 201. The liquid in the drilling fluid is separated from the solid matter with the aid of an auxiliary part, in particular the vibrating mechanism 203 in fig. 6 a. The liquid material, after being separated by the tubular screen, falls to a liquid collection tank 105, 205 mounted on the bottom frame 104, 204 and finally is discharged from the liquid outlet. While the separated solid material is pushed out of the vibrating tubular screen through the solids discharge means 112, 212. The last falling solids outlet 181, 281 is pushed out of the whole device.
It will be appreciated that the tubular screen may have other configurations than the cylindrical shape depicted in the drawings of the present invention, for example, may have an outer wall of a cone, while the inner feed structure secured to the mandrel may have an outer diameter that varies gradually with the taper of the cone to achieve a feed and cleaning effect substantially consistent with the previous embodiments. The tubular screen may also be configured to have an elliptical cylinder, triangular prism, or quadrangular prism, etc., and the outer diameter of the feeding mechanism may be correspondingly configured to match the minor axis of the elliptical cylinder, the diameter of the inscribed circle of the triangular prism or quadrangular prism, thereby achieving substantially identical feeding and cleaning effects as in the previous embodiments.
The drive driving the tubular screen and or the solids discharge means may be controllable, either individually or in combination, by a controller 9 for example. The drive may be an electric motor, or a pneumatic motor, or a hydraulic motor or a fuel engine. The transmission mode can adopt the transmission of a chain, a belt and a gear transmission shaft. The inverter direct drive mode can also be adopted. The frequency and intensity of the vibration generating part of the vibration mechanism can be adjusted by the controller.
Moreover, while advantages associated with certain embodiments of the technology have been described in the context of those embodiments, other embodiments may also exhibit such advantages, and not all embodiments need necessarily exhibit such advantages to fall within the scope of the technology.
