摘要

华北油田泥灰岩储层曾进行多种类型的酸化增产改造工艺,但均未取得理想效果。经过对泥灰岩地层进行大量的油藏地质、室内试验研究以及工程、地质技术人员的反复论证,优选出一种切实可行的酸压改造措施——前置液+高温乳化酸+固体硝酸酸压工艺。经过现场应用,收到了较好的增产效果,为华北油田泥灰岩储层改造措施找到了突破口。

Abstract

Many acid stimulation technologies have been done to muddy limestone reservoir in Huabei oilfield, but achieved a little. Engineers and geologist made many geology data analysis and laboratory experiment, optimized a practicable acid fracturing reform technology, which use ahead fluid and high-temperature emulsified acid and solid nitric acid fracturing technology. Applications have increased production, find a new approach for muddy limestone fracturing of Huabei oilfield.
