大体积人造石岩性密度测井刻度模块的研究

STUDY OF BIG-VOLUME ARTIFICIAL MARBLE FOR DENSITY / LITHO-DENSITY LOGGING TOOLS

设计并制作了一种双参数刻度模块,可以使用同一组模块对岩性密度石油测井仪进行光电吸收指数(Pe值)和密度两种参数的刻度校准。由于双参数人造石刻度模块可完成原需用光电吸收指数和密度两组模块完成的刻度工作,可使人造石刻度模块的数目减少一半,节约了建造成本和保存成本。通过制作小样、中样、大样确定了模块的制作工艺,成功制造出了致密、密度均匀、无开裂的大体积不饱和聚酯树脂模块,并使用特种天平对模块进行了密度定标,使其质量的测量精度达到了克。

A series of big-volume artificial marble with two-calibration-parameters was studied,it was used as photoelectric absorption index（ the symbol is Pe） and density calibration standard for petroleum traditional compensated density / litho-density logging tools. It can save half of construction and storing cost,because a set of two-calibration-parameters standard can replace a sets of density standard and a set of photoelectric absorption index standard. The processing technology was obtained based on a series of experimental data,and the compact,fissureless artificial marbles with uniform density were produced,they were synthesized with unsaturated polyester. The density of the artificial marbles was measured with a special balance,and result was accurate to 1 gram.
