在库车坳陷天然气勘探中,由于目的层段上覆膏盐岩厚度变化大、钻井液密度高使得在该区天然气勘探中卡取层位、发现气层十分困难。从天然气藏的高温异常成因、特征出发，根据目前库车坳陷预探井在钻井中普遍应用综合录井仪，能够对井底温度进行连续测量的生产技术条件，结合库车坳陷古近系—白垩系目的层段主要为高压天然气层的实际，充分利用气层温度异常高的特点，通过对地层温度的连续监测，对地层变化进行了及时、准确地预测，卡准了地层、发现了气层，解决了生产中的难题。

Because of the great change in thickness of the overlying gyprock and the high density drilling fluid in Kuqa depression, it is very difficult to define the boundary stratotype. TDC are used in exploration wells and the temperature at the bottom of well can be measured continuously and the natural gas reservoirs of Eogene-Cretaceous are high pressure reservoirs. Based on this situation and according to the cause and feature of the abnormal high temperature in the natural gas reservoir, we inspected the formation temperature continuously and predicted correctly the change of the formation, defined the boundary stratotype, found the trace of gas and solved the difficulty in work.
