7. Major manufacturers:
Workover rig manufacturers each have their own characteristics and strengths. Due to their large scale and strong strength, large manufacturers mainly produce large-tonnage workover rigs well and export a large number of products. Some small and medium-sized manufacturers are meticulous and professional in small and medium-sized tonnage workover rigs.
100t-180t medium tonnage workover rig: Tianjin DFXK Petroleum Machinery Co.,Ltd
20t-150t medium and small tonnage workover rig: Tonghua Sihai Petroleum Machinery Co., Ltd.
According to its operating structure, it is divided into two types: crawler type and tire type.
Crawler type workover rig is generally not equipped with a Derr, and its power is good off-road, suitable for construction in low-lying muddy areas.
The tire-type workover rig is generally equipped with a self-backing, which has fast walking speed and high construction efficiency, and is suitable for rapid relocation. However, walking and entering the well site are relatively restricted in low-lying muddy areas, rainy seasons, and mud-flooding seasons.
There are many types of tire-type workover rigs used in various oil fields, among which XJ350, XJ250, COOPER LTO-350, Ingersoll Rand 350 and KREMCO-120 are widely used on site.
The crawler workover rig is generally called a well drilling rig, but it is actually a crawler self-propelled tractor that has been modified and added with rollers.
