波兰将采用新的地震技术寻找油气

中国石化新闻网讯 据全球能源网6月21消息称，波兰国有石油和天然气公司PGNiG表示，其地球物理服务提供商Geofizyka Torun公司成为欧洲第一家采用新的地震数据采集技术寻找油气矿床的公司。

波兰石油和天然气公司在一份新闻稿中表示，该公司正在用超轻型无线节点传感器取代迄今这家波兰石油天然气公司在一份新闻稿中表示，该公司将用超轻型无线节点传感器取代迄今使用的有线检波器网络。它们体积小，重量轻，可以在不破坏自然环境和当地社区的前提下进行勘探。

地震勘探是油气勘探的重要组成部分。这种方法的基础是控制地震波的起爆，地震波深入到地球深处，从随后的岩层反射回来，再回到地表，在那里用一种叫做检波器的特殊传感器记录下来。收集到的地震数据有助于在调查区域内确定石油和天然气矿床的位置。

一个覆盖面积达数百平方公里的检波器网络需要电缆连接、传输设备和重型电池。这些设备需要重型车辆搬运。

为尽量减少对环境的影响及对当地居民的滋扰Geofizyka Torun地震数据采集系统实现了一个创新的节点。它是基于一个超轻量的、自主的测量单元——一个配备了集成地震数据测井系统、GPS和高效电池的节点，这些电池足够持续数周的数据记录。

没有电缆，节点可以很容易地隐藏在一层薄薄的土壤下，并使用智能手机进行监控。这种被称为“轻型地震测量”的新方法使承包商能够使用更环保的运输工具。

PGNiG公司总裁Piotr Wozniak表示：“地球物理调查总是适应当地的环境条件、道路基础设施和农业活动。重要的是，我们的地震调查不会破坏当地居民的日常生活。”

Piotr Wozniak补充说：“新无线技术和超轻小型化的整个系统允许我们的地球物理学家地震测量的环境影响降到最低,同时确保分配的地质任务的最优性能即使在苛刻的条件。”

Geofizyka Torun是欧洲第一家使用创新节点地震数据采集系统。到目前为止，该公司已经使用轻型地震设备进行了10次地球物理调查，其中大部分在波兰。

Poland Employs New Seismic Tech

The Polish state-controlled oil and gas company PGNiG said that its geophysical services provider Geofizyka Torun SA became the first company in Europe to employ new seismic data acquisition technologies in searching for hydrocarbon deposits.

The Polish oil and gas company said in a press release that the company is replacing the hitherto used cabled geophone networks with ultra-lightweight wireless nodal sensors. Their small size and low weight allow to conduct exploration with no harm to the natural environment and local communities.

Seismic surveys are an important part of hydrocarbon exploration. The method is based on controlled initiation of a seismic wave, which reaches deep into the earth, reflects from subsequent layers of rock and arrives back at the surface, where it is recorded with special sensors called geophones. Collected seismic data helps to locate oil and gas deposits within the surveyed area.

A network of geophones spread over an area of up to several hundred square kilometres requires cable connections, transmission equipment and heavy batteries. The equipment needs to be carried by heavy vehicles.

In order to minimise environmental impacts and nuisance to local residents, Geofizyka Torun has implemented an innovative nodal seismic data acquisition system. It is based on an ultra-lightweight, autonomous measuring unit – a node equipped with integrated seismic data logging systems, GPS and efficient batteries durable enough for several weeks of data recording.

Devoid of cables, the nodes can be easily hidden under a thin layer of soil and monitored with the use of smartphones. This novel approach, called ‘lightweight seismic surveying’, enables contractors to use more environmentally friendly means of transport.

“Geophysical surveys are always adapted to local environmental conditions, road infrastructure and agricultural activity. It is important that our seismic surveys do not disrupt everyday lives of local residents,” says Piotr Wozniak, President of the Management Board of PGNiG S.A.

“The new ultra-light wireless technology and miniaturisation of the entire system allow our geophysicists to minimise the environmental impacts of seismic surveying, while ensuring optimal performance of the assigned geological tasks even in demanding field conditions,” Piotr Wozniak adds.

Geofizyka Torun is the first company in Europe to use the innovative nodal seismic data acquisition system. So far, the company has carried out ten geophysical surveys using lightweight seismic equipment, most of them in Poland.
