摘要
针对喇嘛甸油田未研制气砂有效厚度解释标准这一情况，在现有气砂地质特征研究的基础上，以气砂的岩性、物性、含气性和电性的关系为依据，采用经验统计法、含气产状法研制出有效厚度物性标准。应用测井、试气和岩心多维空间信息，研制出气砂有效厚度的电性划分标准。该标准深化了气层砂体发育状况认识，应用到喇嘛甸油田生产井的气砂厚度解释中证明是合理、可靠的，为油田气层的储量计算和地质建模等工作提供了基础资料，同时也为油气缓冲区的高效开发提供了坚实的地质依据。
On account of the situation that interpretational criteria of gas sand net thickness have not been studied in Lamadian Oilfield and on the basis of the geologic characteristics study of current gas sand the relationship of lithology, physical property, gas bearing property and electric property, physical property criterion of net thickness is studied with the methods of empirical statistics and gas-bearing occurrence. The electrical property criterion for net thickness division of gas sand is researched applying logging, gas testing and core multidimensional space informa- tion. It is proved reasonable and dependable with applying the criterion to interpret the gas sand thickness of pro- duction well in Lamadian Oilfield, which provides basic data for reserves calculation and geologic modeling of gas formation, deepens the understanding for the developmental situations of sandy body of gas formation, and supplies firm geological evidence for developing the oil/gas buffer zone effectively.
