高温高压气井测试地层出砂的评价方法

Evaluation method of formation sand production in gas well testing with high temperature and pressure

随着石油勘探开发技术的发展和勘探领域的扩大,高温高压气藏、含硫油气藏、凝析油气藏等相继得到开发,而高温高压气井地层测试出砂问题广泛存在于国内外各油田,目前国内外更多的是从防砂工艺和出砂预测做文章,为了及早地控制地层出砂,文中着重从测试压差方面给出地层出砂的一些评价方法,如从抗压强度法、井口油压法、剪切强度法以及射孔流速法上来评价。

With the development of oil exploration and production technique and with the enlargement of exploration area,the oil gas reservoir with high temperature and pressure,sour oil gas reservoir and condensate oil gas reservoir have been developing successively.However,the problem of formation sand production in gas well testing with high temperature and pressure has always existed in almost every domestic and foreign oilfield now.Many people are engaging in sand controlling process and sand production prediction.In order to control formation sand production early,this paper places stress on presenting several evaluation methods in reasonable pressure differential,such as compression strength,wellhead oil pressure,shear strength and perforation velocity.
