摘要
随着勘探开发程度的不断加深,在姬塬地区长8储层中发现多个有利含油区块,预计储量规模可达10.0×108t,是长庆油田发现的具有较好开发前景的深层油藏。与西峰长8储层相比,姬塬长8储层具有埋藏深、岩性致密、地层温度高、闭合应力大、物性差、改造难度大等特点。为了达到提高单井产量的目的,通过不断的探索与试验,针对不同储层特点形成了多级加砂、前置酸加砂、前置水化剂、低伤害压裂液等一系列配套工艺技术,取得了较好的应用效果。
With additional exploration and development,more favorable oil blocks have been discovered in C8 layer of Jiyuan area,expected reserves scale can reach 10.0× 108t.It has a good development prospect to the deep reservoir discovered in Changqing oilfield.Compared with the C8 layer of Xifeng oilfield,the C8 layer of Jiyuan oilfield has many characteristics such as buried depth,lithology density,high formation temperature,big closure stress,poor physical property,hard to stimulate and so on.In order to achieve the purpose of improving single well production,a series of related technology,such as multilevel sand stimulation treatment,lead acid,front hydration agent,has been formed for different reservoir characteristics through continuous exploration and experiment,low damage fracturing fluid,and achieved good application results.
