子洲油田何家集区主力油层储层物性较差,测井曲线对其含油性的识别能力较低。本文通过深入分析储层“四性”关系,认为区内主力储层的“四性”关系符合特低渗储层的基本规律,即岩性控制物性,物性控制含油性,电性是对三者的综合反映;在划分油水层时,需应用自然电位、自然伽玛、声波时差、微电极及深中深感应电阻率等多条曲线综合判断。
The reservoir properties of the main oil reservoir in Hejiadizi of Zizhou Oilfield are poor, and the logging curve has a low ability to recognize oil. In this paper, through deep analysis of reservoir “four sex ” relationship, it is considered that the “four sex ” relationship of the main reservoirs in the area accords with the basic laws of the ultra-low permeability reservoirs, namely lithology control property, physical property control oil content, Sex is a comprehensive reflection of the three; in the division of oil-water layer, the need to use the natural potential, natural gamma, acoustic time difference, micro-electrode and deep deep induction resistivity and other multiple comprehensive judgment curve.
