摘要
膏盐岩上下地层压力系数差距较大,往往造成钻井复杂,给油气勘探开发带来了巨大的困难,膏盐岩层底界的卡取是确保钻井安全的关键。元素录井技术是目前被公认的应用效果较好的卡层技术,通过对岩屑元素含量变化特征进行分析判断,确定膏盐岩地层的底界。目前在西部某区卡层应用中成功率达到95%以上,具有较好的推广意义。
The gap between the upper and lower strata of the gypsum saltstone is large,which often leads to the complicated drilling,which brings great difficulties to the oil and gas exploration and development.The bottom of the gypsum rock is the key to ensure the safety of drilling.Elemental logging technology is currently recognized as a good application of the card layer technology,through the analysis of the characteristics of cutting elements to determine the characteristics of the gypsum rock formation to determine the bottom boundary.At present in the western part of the card layer application success rate of 95% or more,has a good promotion significance.
