On October 14th, three products of "DYJ110/105DD, DYJ75/70DD belt pressure machine, LW380×1400N-BP high-speed centrifuge" independently developed by Baoshi Machinery Co.
, Ltd.
passed the China Petroleum Group Oilfield Technical Service Co.
, Ltd.
in Guanghan, Sichuan Product identification organized by the company
.
The expert group headed by Sun Peidong, the chief expert of PetroChina Offshore Engineering Co.
, Ltd.
, listened to Baoshi Machinery's product overview, standards, quality, performance, HSE control measures, technical characteristics, field application, product comparison, etc.
Reports, as well as user representatives' evaluations Afterwards, he raised inquiries from the aspects of safety, quality, extreme working conditions, maintenance, and services, and made suggestions
.
The expert group believes that the two models of Baotou Machinery's belt-pressing machine products have a high degree of informatization, compact structure, reasonable layout, convenient relocation and installation, and high operating efficiency; high-speed centrifuges have a high degree of automation, and the ability to remove ultra-fine solid particles is strong.
, the effect is obvious in improving the rheology of drilling fluid
.
It is reported that the DYJ75/70DD type gas well pressurized operating machine has completed 26 field applications in Xinjiang, Jingbian and Sichuan-Chongqing regions
.
The DYJ110/105DD gas well pressure-operated machine has been applied on-site in Chuanqing Drilling Company, with a maximum construction pressure of 18.
5MPa, a maximum drilling and grinding depth of 4880 meters, and flushing wells to 4903 meters.
The maximum well depth record of plug and flush wells
.
LW380×1400N-BP type high-speed centrifuge has high separation factor, and the maximum working speed is 4000r/min, which can effectively remove ultra-fine hazardous solid phase particles above 2 microns
.
Equipped with automatic oil and gas lubrication system and automatic feedback adjustment system, it has the functions of operation parameter collection, operation status detection, operation parameter adjustment, early warning and automatic shutdown
.
The centrifuge was industrially tested in the drilling operation in western Sichuan in June 2019 and November 2020, and the accumulative operation exceeded 200 hours
