摘要:
垦利10-1油田沙三段渗透率8.2~839.1 mD,孔喉半径平均值7.84 μm,泥质含量4.2%~32.8%,修井作业漏失修井液极易对储层造成损害。通过分析垦利10-1油田修井作业储层损害机理,得到该油田储层损害原因主要为外来固相颗粒堵塞、有机垢堵塞、无机垢堵塞和水锁。提出了快速过滤技术、加热车加热技术、防水锁技术、防垢技术和自生热解堵技术等“物理+化学”多种技术方法配合使用的储层保护技术。垦利10-1油田现场应用效果表明,本文所提出的储层保护技术可显著提升储层保护效果,使产量恢复期由20 d以上降低至3~6 d,为该类油田储层保护提供了新思路
Abstract:
With the permeability of 8.2~839.1 mD, average pore throat radius of 7.84 μm and shaly content of 4.2%~32.8%, the third member of Shahejie Formation of KL10-1 oilfield is very prone to damage caused by working fluid leakage. Through analyzing the mechanisms of reservoir damage during workover in KL10-1 oilfield, it is concluded that the main causes of reservoir damage include external solid particle blockage, organic scale blockage, inorganic scale blockage and water lock. Thus, the “physic+chemical” combined reservoir protection techniques were put forward, such as fast filtration, heat by heating vehicle, water lock prevention, anti-scaling and autogenous thermal de-blocking. The field application in KL10-1 oilfield indicates that those techniques put forward in this paper can significantly promote the reservoir protection effects, and reduce the yield recovery period from more than 20 days to 3~6 days, which provide a new idea for the protection of similar reservoirs
