摘要

针对中原油田保护油气层技术现状和陕北富县风险探区低孔、低渗储层特征,提出了合理保护天然气藏的新观点。借助OFI - 170 - 50 高温高压动失水仪、YPM - 02 高温高压页岩膨胀模拟试验仪等仪器,对比分析了正电胶钻井液体系强抑制、防水锁的天然气藏保护效果,为钻井完井液保护深层气现场施工提供一定的理论依据。

Abstract

Views of correctly protecting natural gas reservoirs were

put forward and study field of protect natural gas reservoirs

were widened in theory in accordance with protecting natural

gas reservoirs technology state and low hole and low osmotic

reservoirs characteristic1 Result of strong inhibitive and

prevent water lock were analyzed in virtue of OFI2170250

HTHP moving filtrate instrument and YPM202 HTHP

swelling instrument1 Theory bases were put forward for

drilling and complete fluid to protect deep natural gas

reservoirs.
