Oil and gas field drilling waste mud treatment device

Abstract

The invention discloses an oil-gas field well drilling waste sludge treatment device. The oil-gas field well drilling waste sludge treatment device comprises a kiln. The kiln comprises a kiln head, a kiln middle portion and a kiln tail. The kiln middle portion is rotationally connected with the kiln head and the kiln tail respectively. A rotational driving mechanism is arranged below the kiln middle portion. A pulverized coal feed pipe, a material feed pipe, a pulverized coal air inlet pipe and a material air inlet pipe are arranged on the front portion of the kiln head. A pulverized coal hopper is mounted at the upper end of the pulverized coal feed pipe. A material hopper is mounted at the upper end of the material feed pipe. A pulverized coal blower is connected to an air inlet of the pulverized coal air inlet pipe. A material blower is connected to an air inlet of the material air inlet pipe. A lighting-up tuyere is arranged on the kiln head. A discharge outlet is arranged at the bottom of the kiln tail. An exhaust outlet is arranged on the upper portion of the kiln tail. A gas purification system is connected to the exhaust outlet. The oil-gas field well drilling waste sludge treatment device has the advantages that harmless treatment of well drilling waste materials is realized, treated mixtures meet three-level standards of natural soil quality, components are highly integrated, occupied area of the device is small, concentration and continuation in operation are achieved, and treatment efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of oil and gas field drilling engineering, and in particular relates to a treatment device for oil and gas field drilling waste mud. Background technique [0002] Drilling waste mud in oil and gas fields is a multiple stable colloidal suspension system containing clay, weighted materials, various chemical mud treatment agents, a certain amount of dirty oil and drilling cuttings. The hydrocarbons, salts, various polymers, sulfonates, and certain metal ions contained in it are extremely harmful to the environment. If they are not treated, they will definitely cause serious pollution to the surrounding environment of oil and gas fields and groundwater. With the strengthening of people's awareness of environmental protection, the hazards and impacts of oil and gas field drilling waste mud on the environment have attracted much attention, and many countries have listed it as an important project of environmental ...
