Description
技术领域Technical field
本发明涉及海洋平台机械设备附属装置的技术领域，特别是涉及一种深海钻井防喷器导向装置。The present invention relates to the technical field of offshore platform mechanical equipment attachments, and in particular to a deep sea drilling blowout preventer guide device.
背景技术Background technique
众所周知，水下防喷器是不可缺少的海底井控设备，防喷器通常放置在甲板上特定的存储区域，在它工作前，需要相应的移运装置来搬运防喷器送至井口位置，与雨水管连接并经由隔水管起吊进而完成下放作业，其中深海钻井防喷器导向装置是一种在深海钻井防喷器下放的过程中，用于对防喷器的下放轨迹进行限位的装置，其在防喷器安装的领域中得到了广泛的使用；现有的深海钻井防喷器导向装置包括吊运设备，吊运设备设置有吊运绳组件；现有的深海钻井防喷器导向装置使用时，首先将防喷器已送至井口位置，然后将雨水管连接好，然后将吊运设备的吊运绳组件与防喷器的顶部固定部位连接好，然后通过控制吊运设备将防喷器下放至指定位置即可；现有的深海钻井防喷器导向装置使用中发现，防喷器在下放的过程中没有限位装置，因此一旦船体发生晃动，则防喷器与月池两侧的船体发生碰撞的概率较高，因此很可能造成防喷器的损坏或船体结构的损坏，从而导致实用性较差。As we all know, underwater blowout preventers are indispensable subsea well control equipment. Blowout preventers are usually placed in a specific storage area on the deck. Before it can work, a corresponding transport device is required to transport the blowout preventer to the wellhead. It is connected to the rainwater pipe and lifted through the riser to complete the lowering operation. The deep-sea drilling BOP guide device is a device used to limit the lowering trajectory of the BOP during the lowering process of the deep-sea drilling BOP. It has been widely used in the field of blowout preventer installation; existing deep sea drilling blowout preventer guiding devices include lifting equipment, and the lifting equipment is provided with lifting rope components; existing deep sea drilling blowout preventer guiding devices When using it, first send the blowout preventer to the wellhead, then connect the rainwater pipe, then connect the lifting rope assembly of the lifting equipment to the top fixed part of the blowout preventer, and then control the lifting equipment to lift the blowout preventer. The BOP can be lowered to the designated position; during the use of the existing deep-sea drilling BOP guide device, it was found that the BOP does not have a limiting device during the lowering process. Therefore, once the hull shakes, the BOP will not be in contact with both sides of the moon pool. The probability of collision of the hull is higher, so it is likely to cause damage to the blowout preventer or damage to the hull structure, resulting in poor practicality.

与现有技术相比本发明的有益效果为：首先将导向装置通过多组安装块在船体的侧面安装完毕，然后在防喷器移动至井口附近之后，通过吊运设备的吊运绳组件将防喷器吊运至两组加固架之间，然后分别转动两组紧固螺栓使得两组紧固螺栓分别通过两组转动块带动两组挤压板右移，直至两组挤压板将防喷器卡紧在两组加固架和滑动板之间，这时便可以通过吊运绳组件控制防喷器下降，同时防喷器则带动滑动板在两组前限位杆和两组后限位杆的转动轮和限位板的限位下纵向下移，此时防喷器的下降轨迹则与限位板纵向平行，从而通过增设限位装置降低了防喷器下放的过程中，防喷器与月池两侧的船体发生碰撞的概率，因此降低了防喷器的损坏或船体结构损坏的概率，从而增强实用性。Compared with the prior art, the beneficial effects of the present invention are: first, the guide device is installed on the side of the hull through multiple sets of installation blocks, and then after the blowout preventer is moved to near the wellhead, the lifting rope assembly of the lifting equipment is used to lift the The blowout preventer is lifted between the two sets of reinforcement frames, and then the two sets of fastening bolts are rotated so that the two sets of fastening bolts drive the two sets of extrusion plates to the right through the two sets of rotating blocks, until the two sets of extrusion plates move the anti-blowout preventer to the right. The blowout preventer is clamped between the two sets of reinforcement frames and the sliding plate. At this time, the blowout preventer can be controlled to descend through the lifting rope assembly. At the same time, the blowout preventer drives the sliding plate to move between the two sets of front limit rods and the two sets of rear limiters. The rotating wheel of the positioning rod and the limiter of the limiter plate move downward longitudinally. At this time, the descending trajectory of the BOP is parallel to the limiter plate longitudinally. Therefore, by adding a limiter device, the risk of preventing the BOP from lowering during lowering is reduced. The probability of collision between the blowout preventer and the hull on both sides of the moon pool thus reduces the probability of damage to the blowout preventer or damage to the hull structure, thereby enhancing practicality.
