东河塘油田位于新疆库车县,构造上隶属于塔里木盆地塔北隆起轮台凸起东河塘断裂构造带,是我国发现的第一个高产高丰度海相砂岩油田,它的发现是中国海相砂岩油气勘探理论和实践的一次重大突破。油田发现于1990年7月,至1994年探明石油地质储量3323.13×104t,天然气地质储量15.5×108m3,至2009年底累计产原油825.75×104t。石炭系东河砂岩油藏是东河塘油田的主体,其储层东河砂岩段是一套滨岸相砂体,具有厚度巨大、埋深大、储集性能好的特点;其油藏类型为块状底水背斜油藏,产能高,储量丰度高。论述了东河塘油田勘探与发现的历程,剖析了取得勘探成功的实践认识与意义。
Donghengtang Oilfield is located in Kuche County, Xinjiang, and is structurally subordinated to the Dongheitang fault belt in Taibei uplift and Taitai uplift in Tarim Basin. It is the first high-yield and high-abundance marine sandstone oilfield discovered in China. Its discovery was A major breakthrough in the theory and practice of marine sandstone oil and gas exploration in China. Oilfield was discovered in July 1990, to 1994 proven oil geological reserves of 3323.13 × 104t, natural gas geological reserves of 15.5 × 108m3, to the end of 2009 a total of 825.75 × 104t crude oil. The Carboniferous Donghe sandstone reservoir is the main body of Donghengtang Oilfield. The Donghe sandstone section of the reservoir is a set of coastal sand body with large thickness, large buried depth and good reservoir performance. Its reservoir type As a block bottom water anticline reservoir, high productivity, high abundance of reserves. The course of exploration and discovery of Donghentang oilfield is expounded, and the practical understanding and significance of successful exploration are analyzed.
