The purpose of this study is to investigate the
variation in well performance over years by performing step drawdown test. The
well used in this study was drilled by Neojen Engineering in the unconfined
aquifer in Bursa Küçük Sanayi region and is 27 meters deep. The first step
drawdown test was carried out on November 2, 2012. The test was repeated on
March 23, 2017 in the same well. The step drawdown test data obtained from the
field study were solved by the Hantush-Bierschenk and Rorabaugh analytical methods
and the well performance parameters were obtained. The change in well efficiency
and specific capacity were investigated between the dates of the two tests. Suggestions
are presented to increase the well performance.

Anahtar Kelimeler

KADEMELİ POMPALAMA TESTLERİ İLE KUYU PERFORMANSININ ZAMAN İÇİNDE DEĞİŞİMİNİN İNCELENMESİ

Öz

Bu çalışmanın amacı, kademeli pompalama testi ile
kuyu performansının yıllar içerisindeki değişimini incelemektir. Çalışmada
Neojen Mühendislik tarafından Bursa Küçük Sanayi bölgesindeki basınçsız
akiferde açılan 27 metre derinliğindeki kuyu kullanılmıştır. İlk olarak 2 Kasım
2012 tarihinde bir adet kademeli pompalama testi yapılmıştır. Kademeli
pompalama testi, aynı kuyuda 23 Mart 2017 tarihinde tekrar yapılmıştır. Arazi
çalışması sonucu elde edilen kademeli pompalama test verileri
Hantush-Bierschenk analitik metoduyla çözülüp kuyu performans parametreleri
elde edilmiştir. İki testin uygulandığı tarih arasında kuyu verimindeki ve
özgül kapasitedeki değişim incelenmiştir. Kuyu performansının artırılması için
öneriler sunulmuştur.
