Abstract
Telah dilakukan penelitian dan analisa kendali kedalaman terhadap
karakteristik well logging pada batubara dengan menggunakan metode geofisika
well logging. Penelitian dilakukan di daerah Siduung dan sekitarnya, Kecamatan
Kelay, Kabupaten Berau, kalimantan Timur.
Penelitian menggunakan data rekaman dari metode well logging antara
lain gamma ray log dan density log serta hasil pemboran dari tiga line yang ada.
Penelitian dilakukan dengan menganalisa defleksi kurva well logging untuk
mengetahui respon well log pada batubara dan nilai densitas pada batubara serta
menganalisa pola trendline pada grafik respon well log terhadap kedalaman.
Dari hasil penelitian, diperoleh pembacaan log rendah pada batubara.
Respon log relatif menurun terhadap kedalaman dengan pola log yang
berkembang yaitu respon log besar berada pada bagian roof dan floor, respon
relatif kecil pada bagian body lapisan batubara. Hubungan log gamma ray dan
kedalaman sangat lemah, semakin kedalam respon log meningkat. Hubungan
tersebut dipengaruh oleh proses yang terjadi pada saat batubara terbentuk,.
Sedangkan antara log density dan kedalaman memiliki hubungan yang kuat,
semakin dalam respon log semakin besar. Hubungan tersebut dipengaruhi oleh
material yang terkandung di dalam batubara.
Kata kunci: Well logging, gamma ray log, density log, Karakteristik well logging
batubara, Kedalaman.
A study and analysis of the characteristics of the well depth control
logging on coal by using geophysical well logging. The study was conducted in
the Siduung area, Kelay, Berau, East Borneo.
The study used data from the recording well logging methods such as
gamma ray logs and density logs and drilling results from three existing line. The
study was conducted by analyzing the deflection curve well to study the response
of well logging log on coal and coal density values and analyzes the trend line on
the chart patterns of well log response with depth.
From the research, log readings obtained low on coal. Log response
decreases with depth with a growing pattern of the log of the log responses are on
the roof and floor, the response is relatively small in body of the coal
seam. Relationship gamma ray log and depth is very weak, the more into the log
response increases. The relationship be affected by the process that occurs when
coal is formed,. While between log density and depth have a strong relationship,
the greater the log response. The relationship is influenced by the material
contained in the coal.
Keywords: Well logging, gamma ray log, density log, well logging characteristics
of coal, Depth.
