储气井水包油钻井液对综合录井的影响

The influence of Oil in Water Drilling Fluid in Gas Storage Well On Mud Logging Service

针对储气井储层保护问题，结合东濮凹陷文留构造地质特征，储气井三开采用水包油钻井液。通过在文96-储6井的应用证明，水包油钻井液具有很强的抑制性和稳定性，且抗盐能力和悬浮携屑能力强，能够满足欠平衡钻井的要求，并有利于储层的保护，特别适用于气层的保护。该水包油钻井液体系采用5#白油，无荧光，对综合录井影响较小，现场运用多种录井手段可以准确识别油气显示。

Aiming at the problem of reservoir protection combined with the geological feature of Wenliu Structure, Dongpu basin. Through the application in Wen 96-Chu 6 Well etc., the drilling fluid had good rejection capability and resistivity, strong sah tolerance and lifting capacity, could satisfy the demands of underbalaneed drilling operation in complex conditions anti protected the oil and gas resera, oir. It took 5# white oil with no fluorescence and little influence on mud logging service. The hydrocarbon shows cau be exactly identified by various mud logging methods.
