Multi-cylinder lifting and rotation integrated form ocean hydraulic workover unit
The present invention relates to sea oil drilling and production well workover and completion practice apparatus field, be related specifically to Multi-cylinder lifting and
Rotate integrated form ocean hydraulic workover unit.
The more production platform in existing ocean engineering well workover field due to platform load and working area are limited etc. without
Method provides workover rig for oneself, and large size supports platform or ocean module workover rig volume is big and resettlement and hoisting cost are high.Ocean module is repaired
Well machine it is bulky or part support platform on fill workover rig cantilever beam stroke limiting, support platform cannot close to production platform into
Row operation.Operation is carried out using drilling platforms or large-scale support platform, expense expenditure is higher, and available resources is limited, causes
Oily company's development cost is excessively high or even influences field output.
Currently, carry out ocean platform workover treatment hydraulic workover unit equipment or operation mode, mainly there are several types of:
One, such as early stage is with No.4 Machinery Plant of Jianghan Petroleum Administration, Baoji Petroleum Machinery Factory and Nanyang Petroleum Machinery Plant
Based on the ocean workover rig of common land workover rig tactic pattern that produces, structure composition is complicated, shape is huge, flat in ocean
In the case that platform working area or bearing capacity are limited, can not just march into the arena and implement operation, and manufacture, carry, installation cost it is opposite
It is higher.
Two, such as module assembled of the Patent No. CN101725326A of Shengli Oilfield Shanyou Petroleum Technology Co., Ltd.'s invention
Formula offshore platform hydraulic energy-storing workover rig is equipped with horse head using single main fluid cylinder upper end, horse head front end two sides are symmetrically pacified
There are two fixed pulleys for intermediate installation there are two overhead traveling crane fixed pulley, in tripod for dress, and crown sheave and fixed pulley pass through wirerope
Removing for tubing string is realized with the operation form of big hook connects, but can not carry out rotary operation, and job area is limited.
Three, Tianjin science and technology 2011(5): the research for the ocean hydraulic pressure lift workover rig that 31-33 article proposes, one kind of design
Ocean hydraulic pressure lift workover rig cooperates real using 2 groups or multiple groups synchronous hydraulic cylinder jacking travelling beam and multiple groups fixed pulley
The raising of existing hook block, for rotary system still using power swivel, rotation function module integrated level is low.
