摘要： The invention relates to a system for drilling subsea wells from a Mobile Offshore Drilling Unit (MODU), comprising;
a marine drilling riser (8) arranged from the MODU to a seabed located Blow Out Preventer (BOP) (6),
a drill string (3) arranged from the MODU through the marine drilling riser (8) and BOP (6) and further down a wellbore,
at least one closing device (13, 15) arranged in the marine drilling riser (8), or in a high pressure part of the system below the marine drilling riser (8), such as integral with the BOP (6), the closing device (13, 15) being adapted to close the annulus outside the drill string (3). The system further comprises:
at least one mud return outlet (29, 35) fluidly connected to the annulus at a lower part of the marine drilling riser (8) or below the riser (8) as well as below said closing device (13, 15), for flowing mud to a subsea lift pump (40) that is configured to pump the received mud from the wellbore annulus (5) to above sea level, and
a means (8; 38) for separating gas from mud, coupled into the path of flow from the annulus (5) to the subsea lift pump (40), and
a means (8; 35; 10) for dynamic regulation of annular well pressure, coupled to the path of flow from the annulus to the subsea lift pump (40).

The invention further relates to a subsea drilling method for controlling the wellbore annular pressure, a subsea drilling method for maintaining constant bottom hole pressure in a well during drilling and well circulation and a method of drilling a subsea well bore.

摘要： A subsea drilling method for controlling the bottom hole annular pressure and downward injection rate during mud cap drilling operations from a mobile offshore drilling unit with a low pressure marine riser and subsea blowout preventer. The method called controlled mud cap drilling uses the hydrostatic head of a heavy annular mud (fluid) managed or observed in order to balance the highest pore pressure in the well and to control the injection rate, by using a subsea mud lift pump and a control system to regulate the process.

摘要： A method for removing a fluid influx from a subsea wellbore drilled using a pump to return fluid from the wellbore to the surface. The method includes detecting the influx when a rate of the return pump increases. Flow from the wellbore is diverted from the return pump to a choke line when the influx reaches the wellhead. A choke in the choke line is operated so that a rate of fluid pumped into the wellbore is substantially equal to a flow rate through the choke line. Fluid flow from the wellbore is redirected to the return pump inlet when the influx has substantially left the well.

摘要： The invention provides a method and apparatus for performing a plug and abandonment operation on a subsea well. A wellhead interface module is located on a wellhead, which accommodates a volume of wellbore fluid in fluid communication with the wellbore. A system control module receives a signal from a sensor in the chamber and is configured to derive volume data relating to a change in volume of wellbore fluid in the chamber and compares the derived volume data with a volume change expected due to the removal of tubing from the wellbore. In embodiments of the invention, this enables a change in wellbore conditions to be characterised, for example a fluid influx or a fluid loss, from the volume data. The method may comprise providing wellbore fluid to the apparatus to replace fluid which enters the wellbore to occupy the volume vacated by the tubing, and/or removing or adding fluid in fluid influx/loss situations respectively.
摘要翻译：本发明提供了一种用于在海底井上执行堵塞和放弃操作的方法和装置。井口接口模块位于井口，其容纳与井筒流体连通的一定数量的井筒流体。系统控制模块从室中的传感器接收信号，并且被配置为导出与腔室中的井筒流体的体积变化相关的体积数据，并将导出的体积数据与由于将管道从井筒。在本发明的实施例中，这使得能够根据体积数据来表征井筒状况的变化，例如流体流入或流体损失。该方法可以包括向设备提供井筒流体以替换进入井眼的流体以占据由管道腾出的体积，和/或分别在流体流入/流失状况下去除或添加流体。
