切六号构造是柴达木盆地西部坳陷区昆北断阶带上的一个次级构造。昆北断阶带勘探面积3000km~2。2007年根据地震攻关资料部署切6井,在切6井获得高产工业油流,实现昆北断阶带勘探的突破之后,切六号构造至今先后钻预探井、评价井11口,经试油多口井均获高产工业油流。2009年油藏评价切6区块落实储量规模,新增石油控制地质储量xxx万吨,预测地质储量xx万吨。认识切六号构造油层分布规律,对扩大整个昆北断阶带的勘探开发成果,对建设千万吨级高原油气田,有一定的借鉴意义。
The Qie-6 structure is a secondary structure on the Kun-Bei fault zone in the western depression area of the Qaidam basin. Kunbei fault zone exploration area of 3000km ~ 2. According to the seismic data to deploy cut 6 wells in 6, well 6 to obtain high-yield industrial oil flow, to achieve a breakthrough in Kunbei fault-step exploration, the cut No. 6 has so far drill Pre-exploration wells, evaluation wells 11, the test oil wells were high-yield industrial oil flow. In 2009, the reservoir evaluation cut 6 blocks to implement the reserve size, new oil control geological reserves of xxx million tons, forecast geological reserves xx tons. Understanding the distribution pattern of the No.6 structural tectonic reservoir has certain reference significance for expanding the exploration and development achievements of the entire Kunbei fault-order zone and building a 10 million-ton highland oil and gas field.
