中原油田发现亿吨级油气田!本月初,从中原油田获悉,该油田在油气藏勘探领域取得新突破,在东濮凹陷葛岗集洼陷带部署实施的马3001斜井开始试油,为国家能源安全再添“底气”。

东濮凹陷葛岗集洼陷带,属于地质构造上的概念,应对的是鲁豫交界处。而中原油田正位于东濮凹陷之上,过去,受限于工程技术、产业技术等难题,这里的部分油气资源难以获得规模勘探开发。现在,随着中原油田科技攻关“加速度”,东濮凹陷的勘探新突破、难动用储量开发等成果越来越多。在葛岗集洼陷带部署实施的马3001斜井,就是“老油区”挖潜增效的新成果。
新油井于今年5月底开始试油,目前已完成四个阶段的测试求产,试油成果斐然。初步评估葛岗集洼陷带的石油资源量达1.1亿吨,具有较大勘探潜力,有望形成千万吨级油气资源开发区域。油井日产油量高达62.8立方米,日产气量达4.32万立方米,油气当量106.0立方米。标志着油田东濮老区近洼油气勘探取得了重大突破,有望形成千万吨级油气规模增储阵地。
马3001斜井是油田近十年来在东濮凹陷悉心耕耘,试获百方高产工业油气流的重点工程和成功之作。不仅开辟了增储新阵地,有力推动东濮凹陷洼陷带“源内高压”油气资源的规模勘探,而且对后续同类型地区洼陷带油气资源勘探具有积极的借鉴和指导意义。
