摘要
小口径油气地质调查井作为一种地质调查的工作手段,在施工过程中遇到很多问题。以已完成施工的羊D1井、黑富地1井、黑富地2井为背景,对油气地质调查井钻井特点、施工要求和施工难度进行分析,阐述了由于配套设备、钻井工艺方法和相关安全规范等因素不健全,对油气地质调查工程带来的风险和对油气赋存情况评价造成的影响。
The small-diameter oil and gas geology survey well,when used as a geological survey method,faces a lot of problems and difficulties in the drilling process.Based on the completed Well Yang D1,Well Heifudi 1,and Well Heifudi 2,the drilling characteristics,requirements and difficulty in the oil and gas geological survey well are analyzed.The risks in oil and gas geological survey drilling and the impact on evaluation of the oil and gas occurrence due to incomplete drilling equipment,drilling processes and related safety regulations are explained.
