纯梁油田是以复杂断块、低渗透、薄互层为显著地质特征的油藏,近年来采油厂套损井数量呈现逐年上升趋势,影响控制储量495万吨,影响日油251吨。特别是2006年-2010年,年套损井数在20口以上,套损井问题逐渐成为制约油田开发的关键问题。本文针对前期治理效果并不理想现象,开展了套损井治理技术推广应用,取得了较好的效果。
The pure Liang oilfield is a reservoir characterized by complex faulted blocks, low permeability and thin interbedded layers. In recent years, the number of casing damage wells in oil production plants has been increasing year by year, affecting 4.95 million tons of controlled reserves and affecting 251 tons of Japanese oil. Especially from 2006 to 2010, the annual number of casing damage is more than 20, and the casing damage well gradually becomes the key problem restricting the development of the oilfield. In this paper, the effect of pre-treatment is not ideal, carried out casing damage control technology to promote the application, and achieved good results.
