Oil Field Scale And Antiscale Technology Research

In the process of oil and gas fields development, Scaling is the oil Wells and pipelines generally have a problem.Scale exist in formation channel and the cross-sectional area of narrow, pipeline equipment operation ability, increase energy consumption, seriously affect the normal production of crude oil and gathering, and increased the production cost of oil field.Because scaling type and degree is difficult to determine, in the process of oilfield water injection development appeared different degree of damage, so the research on this subject has attracted many attentions of the major oil fields.Based on scale types, mechanism and conventional oilfield of daqing oilfield and xinjiang oilfield, jilin oilfield, such as a large number of research and research in the theory of damage and so on.Conventional oilfield scale type with organic and inorganic scale scale and two kinds of inorganic scale as the main;Scaling is one of the main reasons for injection water, chloride, calcium, magnesium ions content in a certain temperature and pressure conditions.At the same time learn from different scale area, and proposes the corresponding scale samples antiscale mechanism and antiscale technology, to achieve environmental protection, the highly effective antiscale descaling.In this paper a in the oil field injection water injection, injection water quality problems of compatibility between injected water with formation water, between injected water and reservoir rocks adaptability scale problems, for example, the injected water scaling causes, influence factors, the types of fouling and the analysis and study of reservoir adaptability, combining traditional and conventional antiscaling descaling technology, put forward the suitable for the field techniques antiscale method, for the oil field injection water in the process of injection to provide basis for anti-scaling measures, put forward the corresponding reservoir protection measures, to ensure normal operation of water injection system, to effectively inhibit the fouling problem of oil and water Wells.
