摘要
从油气层渗流空间特性、矿物组成、钻井液及工程等因素分析钻井过程中造成油气层损害的因素,探讨监督在现场应采取的保护油气层措施。以大港油田长芦地区板深51断块为实例,通过采取成膜封堵保护油气层技术,有效降低钻井液中的固相及滤液对油气层的损害,取得明显的经济效果。
The factors damaging the oil and gas reservoirs during well drilling in the aspects of the reservoir seepage space features, the mineral composition, the drilling fluid and engineering factors are analyzed, and the on-site supervision measures for the reservoir protection are discussed. The film plugging reservoir protection technology is applied to Shen 51 fault block in Changlu area of Da- gang Oilfield, which effectively reduces the damage of the solid phase in drilling fluid and filtration liquid to the reservoir, and whose economic benefit is evident.
