Description
The utility model relates to the drilling fluid cleaning system equipment in the oil drilling.
In Process of Oil Well Drilling, use drilling fluid cooling drill bit, bottom-hole cleaning usually.From the drilling fluid that the shaft bottom is returned, be entrained with many landwaste, sand mud, must make it to recycle after solid, liquid separates also further the purification through cleaning system.Equipment such as drilling fluid cleaning system involving vibrations sieve, desander, deaerator, centrifuge.Along with improving constantly that drilling technology is required, the cleaning system of drilling fluid is also more and more huger, complicated, thereby drilling cost also improves thereupon; On the other hand, the discarded object got rid of in decontamination process of drilling fluid is also serious day by day to the pollution of environment.Therefore, simplify drilling fluid cleaning system, reduce drilling cost, the minimizing discarded object has been a problem that presses for solution to the pollution of environment.
According to the interrelated data introduction, in colliery and technics of metallurgy mineral dressing technology, the Separation of Solid and Liquid of its mixed ore pulp has adopted various static filterings to realize at present.The static filtering method mainly comprises the press filtration formula, three kinds of filtering type and vacuum filtration formulas of calming the anger.The filter press that press filtration adopts has belt and frame type, and it is to rely on the huge operating pressure of hold-down mechanism with the pulp dewatering between filter cloth; Calm the anger and filter and vacuum filtration is to rely on the pressure reduction of just (bearing) of ore pulp and atmosphere to make ore pulp pass through filter cloth and form filter cake, the realization pulp dewatering respectively.Treating capacity to ore pulp depends primarily on filter cloth both sides pressure reduction and filter screen transmission coefficient.The characteristics of above equipment are that bulk is big, and the filter cloth order is counted height, and Separation of Solid and Liquid is static batch (-type).
In petroleum drilling engineering, in order to simplify drilling fluid cleaning system, carried out relevant research work both at home and abroad, for example the MAX drilling fluid processor developed of the U.S. and China is exactly a kind of single-stage vacuum apparatus, it belongs to static solid-liquid separating equipment continuously, but its Separation of Solid and Liquid Negative Pressure Difference (vacuum) size is limited during because of operate as normal, and keep difficult, and be subjected to factor affecting such as property of drilling fluid (grading), formation lithology very big as viscosity, proportion, one-tenth to the processing of drilling fluid, so fail so far to be applied.
The purpose of this utility model is to simplify existing drilling fluid cleaning system, proposes the drill fluid purification device that a kind of structure is simple, separative efficiency is high, the discarded object environmental pollution is less.
For achieving the above object, the utility model by the following technical solutions:
The drill fluid purification device mainly comprises Separation of Solid and Liquid net (2) and drilling fluid liquid case (1), it is characterized in that the utility model also comprises: in order to quicken the vibrator (6) of drilling fluid Separation of Solid and Liquid, it is installed on the upper end of Separation of Solid and Liquid net (2); The screen tray (14) and the vibrator (6 ') that make solid phase particles quicken sedimentation, screen tray (14) be installed on Separation of Solid and Liquid net (2) below, vibrator (6 ') is installed on the upper end of screen tray (14); With solid phase particles compacting and the automatic spiral chip cleaner of getting rid of (3); In order to the automatic control system (A) of controlling this device operating parameters, it is made up of computer (4), sensor groups (7), data collecting system (8), exciting controller (9), (10) and frequency converter (11) etc., to realize the control to each parameter in the purification process (as pressure, temperature, liquid level, flow, excited frequency, amplitude, chip removal speed, solid capacity etc.).
The utility model has the advantages that: (1) is because this device has adopted vibrator, under the effect of exciting force and drilling fluid import and export pressure reduction, serially drilling fluid is handled, the solid-liquid separation efficiency height, can remove harmful solid phase particles such as wherein landwaste, sand mud effectively, also can remove gas wherein, thereby replace the vibrosieve in the existing cleaning system, and saved equipment such as desilter, desander, simplified cleaning system greatly; And take up room and power demand all less, be convenient to the transportation and energy-conservation, reduced drilling cost.(2) processing to drilling fluid is to carry out in the liquid case, compares with existing cleaning system, and this device loss of drilling fluid is minimum; And, can select the Separation of Solid and Liquid net of different meshes for use, control drilling fluid effectively and handle granularity.(3) the mud cake density height that adopts the spiral chip cleaner to get rid of can reduce to minimum to the pollution of environment.(4) adopt filtering type to make the drilling fluid Separation of Solid and Liquid, solid phase particles is to the friction of Separation of Solid and Liquid net and impact little than vibrosieve, so the application life of Separation of Solid and Liquid net is more much longer than the vibrosieve.(5) adopted microcomputer automatic control system that purification process is controlled, purification efficiency and quality are all improved greatly.(6) needs of this device energy simultaneous adaptation conventional drilling and special drilling well (as desert, sea, low pressure, underbalance, foam drilling etc.) technology.
