Abstract

The invention discloses novel ultra-large-displacement ultrahigh-pressure well cementing equipment. The novel ultra-large-displacement ultrahigh-pressure well cementing equipment comprises a loading carrier. A hydraulic system, a power transmission system, a metering tank, an electrical system, an air path system, a control system, an operating platform, a plunger pump, a clean water manifold, a mud manifold, a high-pressure manifold, a mixing system and an ash feeding manifold are mounted on the loading carrier, wherein the plunger pump is a five-cylinder plunger pump. The five-cylinder plunger pump is adopted to increase the pressure and displacement of the well cementing equipment, and the requirements of high pressure and large displacement are met; slurry mixing is carried out by double mixing devices, the mixing efficiency is improved, the stability of the slurry mixing density is improved, and the requirement of long-time uninterrupted operation is guaranteed; a mixing system pipeline is optimized, multiple sets of mixing systems are integrated on one slurry mixing tank, and the stability of the equipment is improved; and the clean water manifold is optimized, so that watersupply requirements of the multiple mixing devices can also be met at the same time by using one injection pump, and the requirement of large displacement is met.

Description

technical field [0001] The invention relates to the field of petroleum equipment, in particular to a novel ultra-large displacement and ultra-high pressure well cementing equipment. Background technique [0002] The frequency of cementing operations in ultra-deep wells and complex formations is increasing, and mining is becoming more and more difficult. Problems such as high pressure, large displacement, and long-term uninterrupted operations are the major challenges facing mining. At present, the plunger pump of the existing large displacement and high pressure cementing equipment adopts 600hp, which can achieve a pressure of 45Mpa, but it is still difficult to meet the displacement and pressure requirements of the current ultra-deep well oil and gas production. Moreover, the existing single-machine single-pump cementing truck, dual-machine double-pump cementing truck, and thousand-type pump cementing truck cannot meet the operation requirements alone due to the limitation ...

AI Technical Summary

Problems solved by technology

At present, the plunger pump of the existing large displacement and high pressure cementing equipment adopts 600hp, which can achieve a pressure of 45Mpa, but it is still difficult to meet the displacement and pressure requirements of the current ultra-deep well oil and gas production.

Moreover, the existing single-machine single-pump cementing truck, dual-machine double-pump cementing truck, and thousand-type pump cementing truck cannot meet the operation requirements alone due to the limitation of power and displacement. Multiple cementing vehicles operate at the same time, occupying a large space, complicated pipeline connections, and extremely high operating costs
