Lifting-free self-elevating offshore oil well testing equipment

Abstract

The invention discloses lifting-free self-elevating offshore oil well testing equipment, which includes a winch module and a power module providing kinetic energy for the winch module. The winch module includes a winch base, a pair of double-acting hydraulic cylinders capable of ascending and descending synchronously are vertically arranged in the middle of the upper part of the winch base, uppercross beams are arranged at the tops of the pair of double-acting hydraulic cylinders, two fixed pulleys are arranged side by side at the bottom of each upper cross beam, a hydraulic well testing winch is arranged on the one side of the upper part of the winch base, a hydraulic motor is arranged on the other side, opposite to the hydraulic well testing winch, of the upper part of the winch base, and a winding reel is arranged on an output shaft of the hydraulic motor. The lifting-free self-elevating offshore oil well testing equipment has the own lifting function, well testing operation can beconducted without waiting in line for lifting equipment on an offshore oil platform, through the well testing equipment, a lubricator can be lifted over a wellhead, and the restriction on well testing operation by the offshore oil platform facility layout can be lifted without no longer needing to fix the top sheave and the ground pulley through a Christmas tree.

Description

technical field [0001] The invention belongs to the technical field of oil well testing equipment in the offshore oil industry, and in particular relates to a lifting-free self-elevating offshore oil well testing equipment. Background technique [0002] Offshore oil well testing technology has been widely used in the field of offshore oil and gas development in my country and abroad. Well testing technology is an important means for understanding oil and gas reservoirs, evaluating oil and gas reservoirs, monitoring production dynamics, and evaluating completion efficiency, and is an important step in oil and gas development. Offshore oil well testing equipment is the main working part in the process of offshore oil well testing. With different downhole instruments, it can complete downhole operations such as pressure measurement, temperature measurement and bottom hole sampling. [0003] At present, the well testing equipment used on offshore oil platforms are all integral ...

AI Technical Summary

Problems solved by technology

[0004] ① Due to its large size and weight, lifting equipment must be assisted during transshipment. In addition, the utilization rate of lifting equipment on offshore oil platforms is quite high, so well testing operations are often delayed for a long time, which greatly reduces the efficiency of well testing operations , and even greatly affected the entire process of offshore oil and gas exploration and development

However, this utility model can only perform downhole operations such as pressure measurement, temperature measurement, well deviation logging, bottom hole sampling, sand surface detection, wax removal and small-scale salvage for oil and gas wells, and is not suitable for use on offshore oil platforms.
