火山岩

Volcanic rocks play an important role in the oil and gas production.

火山岩在油气天生过程中起很大的促进作用。

Scientists exploring an emerging undersea volcano near the islands of American Samoa in the South Pacific were so amazed to find eels living in the newly formed lava that they nicknamed the population " Eel City ."

On the basis of volcanological study,here we present thirty one K-Ar ages of basaltic rocks and two 14C ages of coke and peat. The history of LGV Quartenary activities can be divided into three main periods, namely Xiaoyishan Period (Early Pleistocene:2.15～0.75Ma), Longang Period (Middle－Late Pleistocene::0.68～0.05Ma) and Jinglongdingzi Period Holocene:1600～1500a.

This *** selected a certain number of representative cores of glutenite have low porosity and low permeability、carbonatite and vulcanite, and carried on best centrifugal force calibration experiments.

本文选取了一定数目有代表性的砂砾岩、碳酸岩和火山岩岩心进行了最佳离心力标定实验，对每块岩心均分别进行了六、七个不同离心力离心后的核磁共振丈量。

Large number of core analysis results showed that 100 psi as the best centrifugal force of calibrating T_2 cutoff value might be not suitable for glutenite cores have low porosity and low permeability and special lithological cores such as carbonatite cores and vulcanite cores.

大量岩心分析实验结果表明，100psi作为标定岩心T_2截止值的离心力对低孔、低渗砂砾岩岩心以及碳酸岩、火山岩等特殊岩性岩心而言可能不适用。

Under best centrifugal force, author selected a lot of representative Glutenite、carbonatite and vulcanite cores and carried on centrifugal experiments and NMR T_2 measurement, and determined T_2 cutoff value of each cores, This *** also selected a certain amount of representative fresh oil-bearing sandstone for calibrating T_2 cutoff value, and analyzed influence of T_2 cutoff value with original wettability of core.

在最佳离心力下，本文选取了大量有代表性的砂砾岩、碳酸岩和火山岩岩心进行了离心实验和核磁共振T_2丈量，确定出了对应岩心T_2截止值大小，本文还选取了一定数目有代表性的新鲜含油砂岩湿样进行了T_2截止值标定，分析了岩心原始润湿性对T_2截止值的影响。

It is discovered through integrating the fractural analysis approach by flexural strength with other methods that the feature of logging facies in effecfire reservoir of Mesozoic vulcanite of the region mainly shows as low density, low neutron, high interval tr...

综合龟裂系数裂缝分析及其他方法发现，该区中生界火山岩有效储集层的测井相特征主要表现为低密度、低中子、高声波时差和高伽马值等特征。

In 2007, according to the plan of CNPC, gas drilling experiments were carried out extensively in Xujiaweiziensis DaQing. Air drilling, nitrogen drilling and atomization/foam drilling were all applied, and the primary attempt was actualized in the intended interval of Yingchengzuensis. It took out remarkable effect, therefore improved and developed the gas drilling technology. Thus the elementary matching technology of gas (atomization/foam) drilling that is fit for sand shale and vulcanite in Region Xujiaweiziensis of DaQing was formed, which will offer valuable experience for the further application and expansion of gas drilling.

根据中油股份公司的安排部署，2007年气体钻井在大庆徐家围子地区进行了大规模试验，应用了空气、氮气和雾化泡沫钻井工艺，并在营城组目的层进行了气体钻井尝试，取得了显著的效果，使气体钻井技术得到了进一步完善和发展，初步形成了一套适合大庆徐家围子地区深层砂泥岩、火山岩地质特点的气体钻井配套工艺技术，为气体钻井的进一步推广应用积累了宝贵经验。
