低渗透油气资源包括低渗透油气藏和致密砂岩气藏,低渗透油气勘探对于现阶段油气资源勘探增储上产具有重要的现实意义。油气化探的勘探原理与利用现今动态看待油气资源的勘探思想和理念相一致,它在低渗透油气资源勘探应用方面具有优势。英南2井致密砂岩气藏上方化探异常空间展布规律可对气藏起到指示作用,化探指标高含量“异常”成因很好地证实了该气藏的保存条件差,聚集天然气散失严重的地质推测。鄂尔多斯盆地某油田低渗透油气藏区SC1、SC2+、DC1等化探指标异常空间分布特征可较为有效地响应油藏空间分布,辩证地认识研究区化探指标应用效果与正确认识化探异常区与已提交储量勘探区两者间的辩证关系同等重要。2个地区化探应用结果表明化探技术可在低渗透油气资源勘探中发挥重要作用。
Low-permeability oil and gas resources include low-permeability reservoirs and tight sandstone gas reservoirs. Low-permeability oil and gas exploration is of great practical significance for increasing oil and gas resources exploration and yield enhancement at this stage. The exploration principles of oil and gas geophysics are consistent with the exploration concepts and concepts of utilizing dynamic current oil and gas resources, which have advantages in the exploration and application of low-permeability oil and gas resources. The abnormal geophysical and geochemical distribution patterns above the tight sandstone gas reservoirs in the Innen-2 well may play an instructive role in the gas reservoir. The high content of geochemical indicators and the genesis of the “anomaly” well prove that the gas reservoirs are poorly preserved and aggregated Natural gas loss serious geological speculation. The spatial distribution characteristics of SC1, SC2 +, DC1 and other geophysical indicators in an oilfield with low permeability in an oil field of Ordos Basin can respond to the spatial distribution of oil reservoirs more effectively, and dialectically understand the application effects of geochemical indicators in the study area and correctly recognize the geochemical anomalies Submitted reservoirs Exploration area The dialectical relationship between the two is equally important. The results of geochemical exploration in two areas show that geochemical exploration can play an important role in the exploration of low-permeability oil and gas resources.
