伏尔加下游地区按勘探程度属老的产油区。该区剩余潜在储量分散于潜伏的,多为非背斜型圈闭中。现探讨查明和预测这类圈闭的方法。根据苏联及其它产油区的勘探工作经验表明,首先是在紧邻已知油气田的一些地区寻找岩性-地层油气藏效果较好,这些地区对形成岩性-地层油气藏的条件比较有利,并且根据以往已钻探井和构造-制图井掌握了充分的资料。鉴于此,在伏尔加下游地区对四个地区进行了研究:乌麦托夫及科托夫(乌麦托夫-里涅夫洼陷及其西坡)、安季波夫-巴雷克列依及卡梅申(安季波夫-谢尔巴克夫古隆起
The lower reaches of Volga exploration area by the oil production area is old. The remaining potential reserves in this area are scattered in the latent, mostly non-anticline trap. Now explore ways to identify and predict such traps. Based on exploration experience in the Soviet Union and other oil-producing regions, it is shown that lithology-stratigraphic reservoirs are first of all found to be effective in some areas immediately adjacent to known oil and gas fields, and these areas are more favorable for the formation of lithologic-stratigraphic reservoirs, and Based on well-drilled wells and tectonic-drawing wells in the past, sufficient information was available. In view of this, four areas have been studied in the lower Volga region: Umettov and Kotov (Umettov-Livneh Sag and its western slope), Andipov-Barrekeli and Kameshin (Antiporpo - Shelby Bakuk paleon up
