压裂是对由于油层物性变差、注水受效状况不好或油层堵塞等原因导致产量递减加快的油井实施的,用以提高储层动用程度和油井产量一种增产措施。本文以河南油田安棚区块低渗透油层改造为例,总结了油田注水开发中,影响油层压裂效果的各种素,对于该地区压裂增产以及重复压裂具有指导意义。
Fracturing is an increase in production due to poor reservoir properties, water injection ineffective conditions or reservoir plugging and other causes leading to production declines accelerated implementation of measures to improve reservoir utilization and oil production. Taking the reconstruction of low-permeability reservoirs in Anpeng block of Henan Oilfield as an example, this paper summarizes the various factors that affect the fracturing effect of oil-fractured reservoirs during the development of oilfield waterflooding, which is instructive for fracturing stimulation and repeated fracturing in this area.
