气测录井在南方页岩气黔绥地1井中的应用

Application of Gas Logging in Shale Gas Well Qiansuidi-1 in South China

摘要:

南方页岩气黔绥地1井为全井取心钻进，通过加工模拟绞车实现了绞车传感器的安装、安装开关代替了悬重传感器的安装、将泵冲传感器安装到皮带轮保护罩上等解决方法，使得气测录井在黔绥地1井中顺利进行。影响黔绥地1井气测录井结果的主要因素有储集层、钻井液、钻井工程以及脱气器，这些影响因素的存在给黔绥地1井气测录井资料解释带来了很大的困扰。为了减少对气测录井资料解释的困扰，必须加强对现场工作人员的录井培训，使录井人员在工作当中能够有效地消除可控因素对气测录井的影响，在一定程度上提高地质钻探气测录井的准确度，为南方页岩气地层划分提供有力的数据支撑。

Abstract:

In the full length core drilling in well Qiansuidi-1 of southern China, the winch sensor installation was realized by processing the simulation winch, the suspended load sensor was replaced by the installation of a switch and the pump punching sensor was installed on the pulley protection cover, which made the gas logging being smoothly carried out. The main factors affecting the gas logging results in well Qiansuidi-1 are the reservoir, drilling fluid, drilling engineering and degasser. In order to reduce the misunderstanding of gas logging data, it is necessary to strengthen the training of logging personnel on site to effectively eliminate the influence led by controllable factors on gas logging and improve the the accuracy of geological drilling gas logging to a certain extent to provide powerful data support for the division of shale gas formations in south China.
