辽河坳陷火成岩油气藏勘探关键技术

摘要/Abstract

摘要： 火成岩油气藏已经成为辽河坳陷油气勘探的重点领域之一。通过多年攻关研究和勘探实践，形成了３项具有辽河特色的火成岩油气藏勘探核心技术。①火成岩油气藏评价技术决定勘探方向：主成盆期的沙三段是火成岩油气勘探的主要层系；近源成藏决定了油气勘探的主要区带；优势岩性岩相和裂缝改造区是有效储层发育的勘探目标。②火成岩体识别与预测技术锁定勘探目标：属性—反演联合地震识别，落实火成岩体的分布范围；火成岩岩相地震识别与刻画，预测优势岩相的分布区；地质—测井的综合识别，确定火成岩类型，识别优势储层。③火成岩储层改造技术有效提高储量动用：针对该区火成岩油藏的^“大排量、低砂比、高强度、多级段塞压裂^”的储层改造工艺，提高产能效果显著，保障了油气勘探成功率。

Abstract:

Igneous reservoir has become an important oil and gas exploration area in Liaohe Basin. Three unique items of key technology have been developed for exploration of igneous reservoirs on the basis of exploration study and practice in the past few years. (1) Technology for evaluation of igneous reservoirs determines the exploration direction. The Es3 formation in the main stage of basin development is the major stratum series of igneous oil and gas exploration. Near-source accumulation determines the main zones and belts for oil and gas exploration. The favorable lithology, lithofacies and fracturing transformation zones are the exploration target of effective reservoirs. (2) Technology for identification and prediction of igneous igneous rock body confirms exploration targets. Attributes – inversion joint seismic identification confirms the distribution scope of igneous rock body while igneous lithofacies seismic identification and description predicts the favorable distribution zone of lithofacies. Integrated geological-logging identification helps determine the type of igneous rock and identifies favorable reservoirs. (3) Technology for transformation of igneous reservoirs effectively improves producing reserves. The ^“large displacement, low sand ratio, high strength and multi-stage plug fracturing^” process for transformation of igneous reservoirs substantially improves productivity and ensures success rate of oil and gas exploration.
