克拉玛依油田注水储层伤害与水质问题分析
Reservoir Damage and Quality Index of Injected Water in Karamay Oilfield
摘要
Abstract
To reveal the reservoir damage of the injected water,this paper aiming at the incompatibility and lower water qualification rate at mixed injection in Karamay Oilfield,discussed the compatibility of swage and eau douce at mixed injection,core damage by the ineligible injection-water,plugging mechanism to the reservoir by suspended particles or emulsified oil,and injection water quality indicators.The result indicates that the sewage has a little incompatibility with eau douce and the injected water also has the same problem with the formation water,but fortunately the loss rate of calcium (magnesium) is all below 30%.Mixed injection will result in core damage,and the more proportion of eau douce,the higher the concentration of suspended particles and emulsified oil,the greater the degree of core damage.Therefore,the largest quantity of injection eau douce allocation should be the minimum required injection allocation in Karamay Oilfield.The recommended index of injection water quality is that the content of suspended particles is less than 5 mg/L,and emulsified oil content is no more than 20 mg/L.关键词
