控因法研究有效储层分布规律

以鄂尔多斯盆地苏里格气田苏120井区为主要研究区域,以盒8段为目的层段。通过测井资料整合数据,将气层、含气层、气水层三类储层厘定为有效储层,并进行有效储层厚度统计,人机联作从井控、砂控、构控等方面进行控因分析,将井区内部有效储层平、剖面规律进行研究,从而可对各小层油气相对储量以及油气的平、剖面分布规律进行指导。结合前人研究成果,得出盒8段各小层平面有效砂岩展布,盒8下亚段为主要储集层段。

Study on Effective Reservoir Distribution Laws by the Method of Controlling Factors

Taking Sul20 well area of Sulige gas field in Ordos basin as main research region, and Hes segment as target interval, gas reservoir, gas bearing formation, gas and water formation of three kinds of reservoirs were determined as the effective reservoir, and the statistical information of effective reservoir thickness was obtained by integrating the logging data. The law of plane and profile of effective reservoir in well area was studied through analysis of well control, sand control, structural control and other controlling factors by man-machine interaction. Based on previous research results, the distribution of sandstone in all the layers of He8 was obtained, it＇s pointed out that the main reservoir interval is lower He8 submember.
