In combination with these experimental phenomena and theoretical analysis, the foam corrosion inhibition mechanisms in foam drilling are first put forward in the paper. They include: the adsorption of foaming agent on steel surface; the complex of foam-stabilized viscosifier with the multivalence metallic ions in formation water; isolating the steel from oxygen by foam; and fixing sands and reducing washout by foam.

结合实验现象和理论分析，首次总结提出泡沫钻井中泡沫的缓蚀机理，泡沫的缓蚀性主要在于：发泡剂在钢铁表面的吸附；稳泡增粘剂能与地层水中的多价金属离子络合；泡沫对氧的隔绝；泡沫能固定砂粒，减少冲蚀。

The mathematical model is dispersed by finite-volume method and the dispersed equations are solved by SIMPLER algorithm. This is the first time to solve a problem of drilling fluid mechanics with the numerical method of Newtonian fluid mechanics.

5首次将牛顿流体力学经常采用的数值方法用于钻井流体力学的研究中：用有限体积法离散钻井液流动和传热的数学模型，用Simpler算法求解该数学模型的离散化方程。

Based on a comprehensive study of drilling and log data, sequences of short-term base-level cycle of turbidite fan in Yanchang Formation of Triassic in Longdong area are divided into three basic structure types: up - deepening non - symmetry, up -shallowing non ?symmetry and symmetry ones according to recognition sign of the interface of the short - term base - level cycle.

以高分辨率层序地层学理论和技术方法为指导，以钻井、测井资料的综合研究为基础，运用短期基准面旋回界面的识别标志将陇东地区三叠系延长组浊积扇短期基准面旋回层序划分为向上"变深"非对称型、向上"变浅"非对称型和对称型3种基本结构类型。
