oil-bearing shale

基本解释

There are many factors to affect identification of oil and gas bearing layers in the sand-shale formation.
在砂泥岩地层中，影响油、气层识别的因素较多，尤其在复杂地质条件下准确识别油气层难度更大。
Lithologies of Chang6 oil bearing set in Lijiacha area is grayish moderate-fine grain arkose in which intercalated beds are deep grey sandy shale and black mudstone.
李家岔区长6油层组岩性主要为浅灰色中细粒长石砂岩夹深灰色砂质泥岩及黑色泥岩。
Based on the seismic attribute-geologic analysis, fault and shale seismic data analysis, integrated with output from available wells, the oil-bearing area can be generally determined.
在地震属性-地质分析的基础上，利用信息分解技术、压制断层及泥岩等地震信息，结合已知油水井的产油气情况，可以大致确定油层的范围。
