鄂尔多斯盆地彭阳演33井区侏罗系储层主要受构造及非均质性控制,油气分布具有隐蔽性,导致在目标油层的划定上难度较大,影响后期产建过程中的开发步骤。本文针对彭阳演33井区油气显示井,通过井-地电法勘探,探明油气藏边界和分布,划定了有利储层范围,研究表明,电阻率由低值区向高值异常区过渡段之间相对高值异常区是较有利的油气聚集区,低值异常区是不利油气聚集的地区。通过后期开发井的实施现状,证实了井-地电法勘探预测有利储层具有较好的应用效果。
The Jurassic reservoirs in the Well Peng 33 in the Ordos Basin are mainly controlled by tectonism and heterogeneity, and the oil and gas distribution is subtle, leading to difficulties in delineating the target reservoirs and affecting the development steps in the post-production process . In this paper, according to the well of oil and gas in Well 33 of PengYangYing, the boundary of oil and gas reservoirs and their distribution are ascertained through well-geoelectric prospecting, and the favorable reservoir range is delineated. The research shows that the resistivity changes from low value area to high value anomalous area The relatively high anomalous zone between the transitional sections is the favorable hydrocarbon accumulation area, and the low anomalous zone is the unfavorable area for oil and gas accumulation. Through the implementation status of the late development well, it is confirmed that the well-geoelectric prospecting and forecasting favorable reservoir has a good application effect.
