Abstract
The invention relates to a technics used to dispose of barren liquor in pressing crack work of artesian well. Through treatment from 1 to 3 class, the technics has a good effect and low cost with adopting barren liquor deriving, dosing to crack, sink-float to remove dregs, solid-liquid separation and straining to clarify. After treatment of only one flow, barren liquor is changed to clean water which can met discharging standard or send into inpouring system of oil extraction. So it solves the problem of processing barren liquor in pressing crack work of artesian well.
Description
One, technical field: the present invention is the process technology that is used for oil drilling frac job liquid waste disposal.
Two, background technology: in the drilling well in oil field, pressure break, job execution, produce a large amount of waste liquid (comprising mud, sewage and other waste liquid).These waste liquids have different character and complicated composition along with the different of the requirement of individual well construction and measure, not only contain a large amount of suspended particles and silt, also have materials such as many solubility inorganicss, organic molecule and macromolecular compound, petroleum-type, colloid to exist.These materials mix up in one and have constituted a kind of highly stable, multistage dispersive compound system, and intractability up to standard is very big, becomes the emphasis and the difficult point of oil field efforts at environmental protection, can not get for many years solving well.The treatment process that mainly adopt in present most of well site is: dispersive waste liquid centralized collection near the collecting tank the well site, remake after for some time by to be allowed its spontaneous evaporation, infiltration and buries processing.Continuous development along with the oil field prospecting exploitation, drilling well, pressure break, fracturing wastewater amount increase fast, and above-mentioned treatment process can't satisfy the requirement of environmental regulation at all, and in case run into rainy season, sewage overflows, and brings serious pollution for farmland, plant, the waterhead area of periphery.
Three, summary of the invention: the purpose of this invention is to provide the process technology that is used for oil drilling frac job liquid waste disposal, technical process of the present invention is: the first step, waste liquid in the waste liquid pool is inhaled into molten gas mixing tank through molten gas suction pump, the medicine of sending here with dosing pump carries out thorough mixing after the water distribution uniformity aerator enters the broken steady sink-float of secondary chamber, stirring the back waste liquid at stirrer flocculates, breaks steady rapidly, scum silica frost rises, the macrobead precipitation; The slag scraper that scum silica frost is moved repeatedly is excluded in slag trapping chamber and flows out outside the jar; Water purification after one-level is handled is from entering the first class purification pond communicating pipe.In second step, the solid-liquid separating machine service pump is sent into solid-liquid separating machine to first class purification water and is further handled; The secondary water purification that is come out by solid-liquid separating machine directly flows to the secondary purification pond, and the mud cake of being separated by solid-liquid separating machine is regularly outside the drain tank.In the 3rd step, the water purification of feeding engine after second-stage treatment sent into secondary filter again and filtered; The clear water (water purification after the tertiary treatment) that is filtered out by secondary filter is direct qualified discharge or enter the waterflood system comprehensive utilization just.
This technology integrates that waste liquid draws, broken steady, the sink-float slagging-off of dosing, solid-liquid separation, smart filter are clarified, and treatment effect is good, cost is low.Waste liquid promptly becomes clear water after through the processing of a flow process, can directly flow to the secondary purification pond by a level water purification, and the mud cake of being separated by solid-liquid separating machine is regularly outside the drain tank.In the 3rd step, the water purification of feeding engine after second-stage treatment sent into secondary filter again and filtered; The clear water (water purification after the tertiary treatment) that is filtered out by secondary filter is direct qualified discharge or enter the waterflood system comprehensive utilization just.
This technology integrates that waste liquid draws, broken steady, the sink-float slagging-off of dosing, solid-liquid separation, smart filter are clarified, and treatment effect is good, cost is low.Waste liquid promptly becomes clear water after through the processing of a flow process, can qualified discharge, and also can directly send into the oil-extracting and water-injecting system and use.This has just solved the difficult problem that oil drilling, pressure break, fracturing wastewater are handled well.
Four, description of drawings: Fig. 1 is the schema that is used for the process technology of oil drilling frac job liquid waste disposal.
Five, embodiment: in Fig. 1, the first step, waste liquid in the waste liquid pool is inhaled into molten gas mixing tank through molten gas suction pump, the medicine of sending here with dosing pump carries out thorough mixing after the water distribution uniformity aerator enters the broken steady sink-float of secondary chamber, stirring the back waste liquid at stirrer flocculates, breaks steady rapidly, scum silica frost rises, the macrobead precipitation; The slag scraper that scum silica frost is moved repeatedly is excluded in slag trapping chamber and flows out outside the jar; Water purification after one-level is handled is from entering the first class purification pond communicating pipe.In second step, the solid-liquid separating machine service pump is sent into solid-liquid separating machine to first class purification water and is further handled; The secondary water purification that is come out by solid-liquid separating machine directly flows to the secondary purification pond, and the mud cake of being separated by solid-liquid separating machine is regularly outside the drain tank.In the 3rd step, the water purification of feeding engine after second-stage treatment sent into secondary filter again and filtered; The clear water (water purification after the tertiary treatment) that is filtered out by secondary filter is direct qualified discharge or enter the waterflood system comprehensive utilization just.
