Prospects for comprehensive utilization of symbiotic/associated oil and gas resources in exploration area of Shengli Oilfield
摘要
Abstract
Various symbiotic/associated oil and gas resources have been found in the exploration area of Shengli Oilfield,and some of them serve as strategic resources for guaranteeing the security of national defense,agriculture,high-tech,and other industries,which are of great value in development and utilization.The current exploration and development status,occurrence characteristics,ore-forming conditions,and comprehensive utilization prospects of helium,brine(potassium salt),and uranium ore that have been deeply studied and industrially produced in China were analyzed.The results show that ① the high helium anomalies are mainly dis-tributed in more than 10 areas of the Jiyang Depression and Qaidam Basin,as well as in multiple layers of the Proterozoic-Cenozoic,associated with conventional natural gas,non-hydrocarbon gas,and shale gas;② Jiyang Depression and Qaidam Basin provide the paleoclimate and palaeoenvironment for developing brine(potassium salt)from the Paleogene to the Quaternary.The oilfield water in Dongying Sag contains abundant amounts of bromine,lithium,and potassium,and more potassium and lithium are found in the oilfield water in Qaidam Basin,with the content in some areas reaching industrial grade;③ the sandstone is the pri-mary type of uranium ore.The multiple wells in Chepaizi Uplift exhibit highly abnormal gamma values in the Cretaceous and Neo-gene,indicating that this area is the most favorable prospective area of associated uranium ore.In other exploration areas of Shengli Oilfield,such as Tuha Basin,Qaidam Basin,and Jiyang Depression,the forming conditions for uranium ore are observed,includ-ing uranium sources,structures,lithofacies,hydrogeology,etc.,and natural gamma logging data from some wells show high ab-normal values.Overall,the symbiotic/associated oil and gas resources in the exploration area of Shengli Oilfield show the character-istics of various types,multiple layers,and wide abnormal areas.It is necessary to fully take the natural advantages of Shengli Oil-field in terms of basic exploration data,basic geological achievements,and engineering facilities,to systematically carry out re-search on the reservoir forming(ore-forming)law of symbiotic/associated oil and gas resources,evaluate resource potential,and innovate extraction technology as soon as possible,to achieve a new business growth pole.关键词
