摘要
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。
Abstract
W ith the developm ent o f o il exploration and production
technique and w ith the en la rgem ent of exp lo ration area, the oil
gas reservoir w ith h igh temperature and pressure, sour o il gas
reservo ir and condensate o il gas reservo ir have been
developing successively. H owever, the problem o f fo rma tion
sand production in gas w ell testing w ith high tem pe ra ture and
pressure has a lw ay s ex isted in alm ost every domestic and
fore ign o ilfie ld now. M any people are engag ing in sand
contro lling pro cess and sand production prediction. In o rder
to contro l fo rm ation sand production early, th is paper p laces
stress on presenting severa l evalua tion m e thods in reasonab le
pressure d ifferen tia,l such as com pression streng th, we llhead
o il pressure, shear strength and perforation ve loc ity.
