English term or phrase: abrasive formation
Definition from Hacettepe University:
A rock consisting of small, hard, sharp-cornered, angular fragments, or a rock, the cuttings from which, produced by the action of a drill bit, are hard, sharp-cornered, angular grains, which grind away or abrade the metal on bits and drill-stem equipment at a rapid rate.

Example sentence(s):
  • Coiled tubing drilling was selected due to the small production casing and the aggressive curve section buildup rate in the hard, abrasive formation. Hart Energy Publishing, LP
  • In general, an impregnated diamond bit with a low identifying number such as “D2” would be used to drill a relatively soft, fractured and abrasive formation. Dimatec Inc
  • If used in the correct rock type then the drilling speed is faster than with other bits designs. These bits can't be used in soft and high abrasive formation rocks. Rod Pietsch

Definition from own experience or research:
含有大量的石英、斜長石、微斜長石等比較堅硬的礦物成分, 研磨性大且十分堅硬的砂岩地層,鑽井難度大。

Example sentence(s):
  • 據大慶油田鑽探鑽井一公司工程技術人員介紹,“鶯深2井”所處區塊地層可鑽性級值高、地層硬度高、地溫梯度高、地層研磨性強,鑽井難度大。 - 新華網  
  • 開發這種裝置的意圖不是將其用於從上至下鑽完全井,而是將其用於鑽非常難鑽、特別耗時和成本較高的特定井段,如極硬或極具研磨性地層。試驗證明,使用PID裝置的鑽進速度比其他常規鑽井技術的鑽速要快許多倍。 - 資源網  
  • 鑽頭在鑽進超研磨性地層時,胎體的磨損非常嚴重.文章分析測試了這類地層的可鑽性,具有針對性地採用加大胎體中金剛石濃度的方法來保護胎體,極大地延長了鑽頭的壽命. scholar.ilib.cn/A-QCode~zbkj200603008.html - ilib
