摘要
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。
Donghetang Oil Field is locsted in the Donghetang Fracture Bell of Tabei Uplift, Tarim Basin. It is the first madne sandstone oil field that has been discovered in China. The field is discovered in June, 1990 as high yield oil was ddlled out at the Carboniferous Donghe Sandstone in Well DH-1. It held the total proved oil and gas geologic reserves in-place of 33.2313×104t and 1559×108m3, respectively in 1994 and it has yielded 8.2575×106t of crude oil in total till the end of 2009. The Carboniferous Donghe Sandstone Member is a thick set of good dsep-buded anticlinal littoral sand body reservoir with high abundance of reserves. The history and experience of exploration and exploitation as well as the technology, methods and theory that succeed in oil exploration are reviewed in detail,
