气测录井在涪陵页岩气田焦石坝区块勘探开发中的应用

摘要

Gas logging,also known as chromatographic logging,is a kind of test technology while drilling,to determine the nature of formation fluid by measuring the component and content of natural gas in drilling fluid as well as to carry out assessment of the reservoir indirectly.This technology is one of the basic way in discovery and evaluation of oil and gas reservoir,featuring real-time convenience,high accuracy and efficiency.The application of gas logging in Jiaoshiba Block,Fuling shale gas field,has received good results integrated with drilling data collected for years.%气测录井又称为相色谱录井，是一种随钻测试技术，主要是通过对钻井液中天然气的组分和含量进行测量，从而判断地层流体性质，间接评价储层。该技术是目前石油钻探中发现和评价油气层的基础方式之一，具有实时方便，准确度高，效率高的特点。气测录井技术在涪陵页岩气田礁石坝区块进行应用，结合该气田多年钻探的成果资料，取得了非常好的效果。
