Embodiment Construction

[0023] Such as figure 1 A specific embodiment shown includes a first collection tank 1, a second collection tank 5, a multi-stage solid-liquid separation module 10, a deep processing module 15 and a delivery system.

[0024] The first collection tank 1 and the second collection tank 5 are formed by dividing a silo body. An overflow baffle is arranged in the bunker body. The overflow baffle is lower than the silo wall of the bunker body, and the overflow baffle They are the first collection tank 1 and the second collection tank 5 respectively. The volume of the second collection tank 5 is smaller than that of the first collection tank 1.

[0025] The first collection tank 1 is provided with a fixed receiving tank 2 connected with the first collection tank 1; the second collection tank 5 is provided with an adjustable receiving tank 6 connected with the second collection tank 5; A horizontal guide rail is fixed on the collection tank 5, and the adjustable receiving groove 6 is slida...

Abstract

The invention discloses an integrated waste drilling mud treatment system capable of treating while drilling. The integrated waste drilling mud treatment system capable of treating while drilling comprises two collecting tank bins, a multi-stage solid-liquid separation module, a deep treating module and a conveying system. The multi-stage solid-liquid separation module comprises a centrifugal machine, a liquid transfer bin, a coarse-mesh dryer and a fine-mesh dryer, wherein the mesh number of the fine-mesh dryer is larger than that of the coarse -mesh dryer, and a liquid outlet of the centrifugal machine is connected with the liquid transfer bin. The deep treating module comprises a water treating regenerator and a liquid recovery tank, and a liquid outlet of the water treating regenerator is connected with the liquid recovery tank. A feeding port of the coarse-mesh dryer is connected with the first collecting tank bin, and a feeding port of the fine-mesh dryer is connected with a liquid outlet of the coarse-mesh dryer and the second collecting tank bin. The integrated waste drilling mud treatment system capable of treating while drilling has the advantages that on one hand, use of solidifying chemical agents can be reduced greatly, so that harmful solid discharge is reduced fundamentally; on the other hand, liquid recovery ratio after treatment is increased greatly, so that waste drilling mud is reduced fundamentally.

Description

Technical field [0001] The invention relates to an integrated treatment system for drilling waste mud while drilling. Background technique [0002] In the process of oil and gas exploration and development drilling, the vibrating screens, de-sanders, mud separators and centrifuges in the drilling facilities will produce mud. These waste muds are composed of solid phase, liquid phase and chemical treatment agent. A large amount of clay, aggravating materials, various chemical treatment agents, sewage, slop oil and multiple colloidal suspension systems of drill cuttings, if not treated, will cause immeasurable harm to the natural environment. [0003] At present, there are three domestic treatment methods for waste drilling fluid: direct discharge, large-circulation tank precipitation and solidification treatment. [0004] (1) Direct discharge method [0005] Some waste drilling fluids can be directly discharged into the environment, but this is limited to low-toxic or non-toxic drilli...
