海上酸化施工技术探讨

Analyzing the Technology of Acidifying Operation at Sea

本文概述了碳酸岩盐及砂岩地层的酸化机理 ,回顾了KT -2钻井平台在渤海海域海上酸化施工的应用情况 ,并对酸化后增产效果作了分析 ,提出了对海上酸化施工的一些认识。

This paper summarily describes the acidification principle of carbonate and sand formation,reviews the application of acidifying operation on the Kan Tan -2 rig at Bohai sea, analyses the effects of well test after acidifying. Author puts forward some suggestions concerning the acidifying technology at sea.Key words:acidification principle;acidifying operation;acidifying effect;suggestion dichloride was determined by gas chromatography.The low limit of detection was 0.08 μg/mL.This method has been used to determine the trace ethylene dichloride in the epoxyethane circulating reactor gas with high sensibility and accuracy.
