據(jù)油田技術(shù)9月9日消息稱(chēng)，Equinor在2018年從道達(dá)爾接管該油田的運(yùn)營(yíng)商之前，對(duì)馬丁林格油田的鉆井進(jìn)行了深入分析。

這項(xiàng)審查得出的結(jié)論是，有幾口井沒(méi)有必要的防護(hù)層。因此，Equinor計(jì)劃鉆探新井，以確保安全生產(chǎn)。

2018年之前在馬丁林格油田鉆探四口氣井中存在防護(hù)層缺陷，這些被認(rèn)為不適于安全生產(chǎn)。

派特洛對(duì)油井防護(hù)層進(jìn)行了獨(dú)立評(píng)估，以支持了運(yùn)營(yíng)商的觀點(diǎn)。

Equinor負(fù)責(zé)技術(shù)、項(xiàng)目和鉆井的代理副總裁Geir Tungesvik說(shuō)：“目前，這些井被認(rèn)為是安全的，但我們將繼續(xù)封井，并對(duì)其進(jìn)行持續(xù)監(jiān)控，直到我們通過(guò)從其他井中開(kāi)采來(lái)降低地層壓力。安全始終是第一要?jiǎng)?wù)。”

馬丁林格工廠專(zhuān)為油氣混合而設(shè)計(jì)，需要以一定速度生產(chǎn)的氣井來(lái)啟動(dòng)和生產(chǎn)。

Tungesvik 表示：“我們的首要任務(wù)是確保安全啟動(dòng)該領(lǐng)域。我們的首要任務(wù)是確保油田的安全啟動(dòng)。因此，除了開(kāi)發(fā)與運(yùn)營(yíng)計(jì)劃(PDO)中剩余的兩口氣井外，我們計(jì)劃再鉆三口新的氣井，以按照原計(jì)劃生產(chǎn)。”

鉆探三口新井的成本總計(jì)約為2 0億挪威克朗。

Equinor將向挪威當(dāng)局提供所有正在開(kāi)發(fā)的項(xiàng)目的最新信息，包括Covid-19的后果。該計(jì)劃將與十月份國(guó)家預(yù)算的發(fā)布一起發(fā)布。

馬士基Intrepid鉆機(jī)最近開(kāi)始在馬丁林格進(jìn)行鉆探作業(yè)。

Equinor是馬丁林格（70％）的大股東和運(yùn)營(yíng)商。派特洛（30％）是唯一的合作伙伴。

Equinor to conduct further drilling at Martin Linge field

Equinor has conducted an in-depth analysis of the wells drilled at Martin Linge before the company took over as the operator of the field from Total in 2018.

This review concluded that several of the wells do not have the necessary barriers. Equinor therefore plans to drill new wells in order to ensure safe production.

In the four gas wells that were drilled at Martin Linge before 2018 well barrier deficiencies that are considered to make them inappropriate for safe production have been established.

Petoro has carried out an independent assessment of well barriers that support the operator's view.

“The wells are considered safe as they are now, but we will keep them plugged and under continuous monitoring until we have reduced the pressure in the formation by producing from other wells. Safety is always priority number one,” said Geir Tungesvik, acting EVP for Technology, Projects and Drilling in Equinor.

The Martin Linge plant is designed for a mixture of oil and gas, and needs gas wells that produce at a certain rate for start-up and production.

“Our number one priority is to ensure safe start-up of the field. We will therefore plan to drill up to three new gas wells in addition to the two remaining wells from the plan for development and operation (PDO) for the field to produce as originally planned,” said Tungesvik.

The costs of drilling up to three new wells total about NOK2 billion.

Equinor will give an update on all projects under development to Norwegian authorities, including the consequences of Covid-19. The plan will be published in connection with the presentation of the state budget in October.

The Maersk Intrepid drilling rig recently started the drilling operations at Martin Linge.

Equinor is the majority shareholder and operator of Martin Linge (70%). Petoro (30%) is the only partner.
