断块油田防砂效果研究方法

Study Method on Sand Control Effect in Fault Oilfield

我国的第三系出砂油层在构造特征上大多呈现多断、多阶，垒、堑相间的面貌，且由于陆相沉积地层非均质性严重，使防砂工艺必须密切结合断块油田的具体地质情况才能发挥良好的效果。文中结合断块油田的实际，分析了影响防砂效果的因素和判断依据，提出利用物理建模—数据采集—数据处理的研究方法在断块油田进行防砂效果研究，对防砂效果由定性评价转换为定量评价。

The tectonic charateristic of the Tertiary Period unconsolidated sandstone reservoir in Chinais almost presented by multiple fault and multiple terrace combining with rampart and moat. According to the serious anisotropy of continental deposit formation, sand control technology must be meeting with the individualcondition of fault oil field if this technology has good effect. Combining with the condition of fault oil field, overallfactors which can influnce sand control effect, the author gives study method which uses phsical model-data acquisition-data process to study sand control effect of fault oil field at first time in China. This is very importantto convert qualitative evaluation of sand control effect to quantitative evaluation.
