Protecting Hydrocarbon Zone to Improve the Ability of Identifying Pay Zones with Log Data

李厚裕．保护油气层提高测井资料识别油气层的能力．测井技术，１９９７，２１（２）：１４２～１４７钻井过程中减小泥浆对地层的污染，可为测井提供良好的井眼环境，增强测井信息的分辨能力，从而大大提高地层参数与油气识别精度，及时发现油气层或油气田。测井实例证明，在钻井、完井、修井、注水及生产过程中保护油气层是十分重要的。

Decreasing mud invasion during drilling may provide a good borehole condition for well logging, hence reducing its influence on log data and improving the accuracy of formation parameters. Thus, hydrocarbon zone can be identified correctly. Case history shows that protection of pay zones is very important in drilling, well completion, workover treatment, water injection and the whole production process.
