摘要
The authors studied Bohai sea SZ36-1 oil field scaling conditions and analyzed its formation characteristics as well as injected water characteristics. According to the Oddo-Tomson saturation index, this oil field scale can be calcium carbonate scale and calcium sulfate scale. Research indicates that calcium carbonate (CaCO3) scale will form during the process of water injection, but calcium carbonate scale is not the main scaling type. With our own experiment measuring device and scale static and dynamic experimental evaluation data, the amount of actual scaling buildup can be calculated and the extent of the formation permeability damage caused by the amount of scaling buildup can also be studied. On this basis, the scale inhibitor can also be well selected. Conclusion of the study will help guide oil field water injection practice and reduce formation damage, and thereby enhance oil recovery.
