摘要

压裂是吉林低渗透油田新区开发和老区稳产的主要增产措施,而压裂效果的好坏却受着诸多因素的影响。从分析影响因素入手,提出在压裂后的适当时期对人工裂缝进行处理,清除伤害裂缝的物质,恢复裂缝的导流能力,提高油井的产量,延长压裂的有效期。

Abstract

Fracturing is one of the main stimulation measures for developing the new field and stabilizing the production of matured field in low permeability J1lin oilfield. The effects of fracturing are influenced by a lot of factors. This paper, starting from the analyzing of the influential factors, points out that the man-made fractures should be treated in the proper time after fracturing, the substances damaging the fractures must be cleaned out, the flow conductivity of the fractures should be recovered. By doing so, the output of the oil well can be increased, and the effective period of fracturing can be prolonged.
