随钻测压工具在崖城13-1气田A9井的应用

摘要

In order to obtain current formation pressure of Yacheng 13-1 Gas Field,verify the producing degree of section 3 in Lingshui Formation,and avoid the risk of conventional wireline logging, Stetho-Scope 675 type tool was used to draw formation fluid for pressure test after Well A9 of the gas field was finished. According to the test data obtained, formation pressure and formation physical parameters were determined, which gave further understanding of the gas reservoir,and guided subsequent production operation. This paper briefly presents the principle, technical features and the testing process of StethoScope 675 type formation pressure test while drilling tool,and Well A9 testing process.%为获得崖城13-1气田目前的地层压力数据,验证该区块陵水组3段储层动用程度,规避常规电缆测井风险,该气田A9井在完钻后,使用StethoScope 675型随钻测压工具进行了压力测试.根据测试所获得的数据,可确定地层压力及地层物性参数,增加对气藏的了解,对后续的生产作业有指导作用.简要介绍了StethoScope 675型随钻测压工具的原理、技术特点、测试流程及A9井测试过程.
