The CLIMAP 18k bp sediment data files were compiled by Oregon State University. The files contain micropaleontology in the form of faunal counts of diatoms, planktonic foraminifera, coccoliths, and radiolaria, as well as stratigraphy (percent fine, coarse, total carbonate, oxygen 18 and carbon 13), and geochemistry (percent opal, quartz, and organic carbon), and inferred sea surface temperatures for 635 ocean sediment cores.

此数据库的沉积物数据由Oregon州大学收集编制，包括硅藻动物群、浮游有孔虫目、颗石藻、放射虫目中的古微生物，以及地层中碳酸盐、氧18和碳13的百分含量和由635个海底沉积物钻芯样本推测得到的海面温度。

Based on the example in Min114 block at Xinmin oil field,the authors analyze the relation of the fracture and crustal stress,measure the direction and length of the hydraulic fracture by receiving the microseism signals when the terrene is broken,which provides a basis for deploying reasonable flood pattern for development of low permeability reservoir.

Through the research of this paper, the new standpoint is verified theoretically that borehole collapse will be caused by radial shear fracture in formations resulted from over-high drilling fluid density, and a new concept is given out that to maintain a stable borehole the maximum and minimum mud density should both be controlled.

通过本论文的研究，从理论上证实了泥浆密度过高将导致地层产生径向剪切裂缝而造成井壁坍塌的客观规律，提出了稳定井壁需要同时控制泥浆密度上、下限的新观点。

Mechanical reason of borehole collapse in brittle shale is researched. With the elastic theory, the formula for calculating the maximum and minimum drilling fluid density that would cause the initial shear fracture in vertical and inclined borehole is derived and the influence of formation non-linear deformation property is taken into account. The solution of the formula is given by iteration method.
