高35-2井和高35-1井是冀中坳陷蠡县斜坡大百尺构造带高35断块上距离很近的两口井,高35-2井使用屏蔽暂堵钻井液,高35-1井未使用屏蔽暂堵钻井液。通过对比分析两口井的电测曲线可以发现,高35-2井的滤饼薄,钻井液侵入半径小,油层段深感应电阻率受钻井液侵入的影响小,油水层电测曲线特征分明,说明采用屏蔽暂堵钻井液能提高测井解释的准确性,有利于保护和及时发现油气层。
High 35-2 wells and high 35-1 wells are Jizhong depression Dabaifeng tectonic belt on the 35 block on the very close distance between the two wells, high 35-2 wells using temporary shield blocking drilling fluid, high 35 -1 well did not use the temporary shield blocked drilling fluid. Through comparative analysis of the electric measurement curves of the two wells, it can be found that the filter cake in high 35-2 well is thin and the intrusion radius of the drilling fluid is small. The deep induction resistivity of the reservoir section is less affected by the intrusion of drilling fluid. The electric measurement curve of the oil- This shows that the use of temporary plugging shield drilling fluid can improve the accuracy of logging interpretation, is conducive to the protection and timely detection of oil and gas layers.
