疏松砂岩油藏出砂是造成油井低产、水井欠注的主要原因,影响油田正常生产。雁木西油田是典型的疏松砂岩油藏,为选择有效的防砂技术,先后试验了多种机械、化学、复合和压裂防砂技术,取得很好效果,根据雁木西油藏出砂特点和油田生产实际,确定了油井采用油管悬挂防砂为主的多元防砂技术和压裂充填防砂技术,注水井选择JTS-阻砂剂防砂技术,有效地解决了油藏出砂对油田生产的影响,油、水井开井时率明显提高,油田增产、增注效果显著。
Unconsolidated sandstone reservoir sand production is the main reason for the low production wells, well undershoot, affecting the normal production of oilfields. Yanmuxi Oilfield is a typical unconsolidated sandstone reservoir. In order to choose effective sand control technology, a variety of mechanical, chemical, composite and fractured sand control technologies have been tested and achieved good results. According to the sand production characteristics of Yanmuxi reservoir and oilfield production In practice, the multi-element sand control technology and fracturing sand control technology are mainly adopted for oil well suspension pipe sand control. The JTS-sand control agent sand control technology is selected for water injection wells to effectively solve the impact of sand production on oilfield production. Oil and water wells Open well rate was significantly increased oil field production, significant increase effect.
