摘要: 针对渤海某区块在石油钻探中所出现的钻头卡死、磨损严重、过早失效以及钻具容易损毁等问题,利用X射线衍射方法对从渤海某区块深部所取的岩样进行全岩矿物成分百分含量和粘土矿物成分相对含量的定量分析,将分析结果进行统计与曲线拟合,对应实验结果进行现场应用。结果表明:每种岩性所含的全岩矿物百分含量和粘土矿物相对含量是不同的,不同的全岩矿物成分对岩性软硬程度和岩石形成的影响是不同的,对钻头的选型以及可钻性的研究都将产生重要影响;不同的粘土矿物相对含量钻井液的配制和选用以及对油气资源的钻探也起着关键性作用。此外,对部分全岩、粘土矿物成分进行了曲线拟合,可为岩石矿物的研究提供一定的借鉴。研究结论对于提高渤海某区块的油气资源的勘探、开采具有参考价值。

Abstract: For a certain block of Bohai, problems of jamming, severe wear and premature failure of the drill bit and easy damage of the drilling tool appear during oil drilling. Aiming at this issue, we perform quantitative analysis of percentage of whole rock mineral constituents and the relative content of clay mineral components by using X ray diffraction method, carry out statistics and curve fitting with the analysis results, and correspond the test results with field application. The analysis results show that each lithology of whole rock mineral content and relative content of clay mineral is different. The influence of different whole-rock mineral composition on the hardness of the rock and the forming process is also different. Therefore, it has an important effect on the selection of drill bit and its drillability. The relative content of different clay minerals plays a key role in the preparation and selection of drilling fluid and oil and gas drilling. And we conduct curve fitting on a part of the whole rock and clay mineral composition, which can provide some reference for the research of mineral rock. The research conclusion has reference value for gas resources exploration and mining.
