Gate valves are common shut-off valves in piping systems. They control media flow by moving the gate along the seat sealing surface vertically, and are generally not used for flow regulation. During opening and closing, the gate slides relative to the seat sealing surface, making them suitable for clean media pipelines. A gate valve mainly consists of the body, bonnet, gate, stem, sealing pair, and drive mechanism. By gate structure, they are divided into parallel and wedge types. Wedge gates offer better sealing performance and wider application; parallel gates have a simpler structure and are mostly used in low-pressure conditions. Stems are classified as rising or non-rising. Rising stems allow direct observation of the opening stroke, while non-rising stems save space and sui

Recently, the pump setting depth at Well Yubei 20-9 in the Lukiqin Oil Production Management Area of Tuhai Oilfield successfully reached 3,213 meters, breaking through the long-standing technical barrier of 3,000 meters for rod-pump lifting systems. This achievement sets a new record for lifting depth using this technology within China National Petroleum Corporation and provides a replicable technical solution for efficiently developing deep reserves in mature oilfields. Currently, development of mature areas in Tuhai Oilfield has entered the mid-to-late stage, with increasingly evident challenges such as deep reservoir burial, insufficient formation energy, and difficulties in economically exploiting deep reserves. Due to limitations imposed by the rated load capacity of

Since the beginning of this year, Jinzhou Petrochemical has focused on improving quality and efficiency in its core refining and petrochemical operations, deeply tapping into profit potential from its specialty marine fuel products, achieving outstanding results in production.

To maximize capacity for low-sulfur marine fuel, Jinzhou Petrochemical's technical team continuously refined blending formulas and precisely adjusted process parameters. Starting in May, daily marine fuel production steadily rose. To address blending quality risks, the Production Operations Department systematically carried out preparatory measures such as pipeline purging, pr

As of May 15, the first batch of group energy-storing fracturing wells at Xinjiang Oilfield's First Production Plant (Hongshan Company) have shown impressive production performance after being put into operation. Among them, five wells are producing by natural flow, with a daily incremental oil production of 15 tons across the well group and an average daily increase of 1.7 tons per well. The Keshang Formation reservoir in the Hong60 well area of the First Production Plant is a lithology-controlled structural reservoir, representing a typical medium-porosity, ultra-low-permeability reservoir with complex geological conditions. The block contains 29 oil and water wells, but due to a large well spacing of 350 meters, water flooding efficiency has been poor. Conventional fra

On May 21, reporters learned that the first wind turbine of the Renqiu 150,000-kilowatt wind power project in North China Oilfield has been successfully installed, demonstrating strong momentum in new energy development.

On May 6, it was learned that Xinghua 12-44X well—the core production well of the CCUS-EOR pilot test at Bayan Oilfield in North China Oilfield—successfully completed its fluid profile logging operation. This marks a significant breakthrough in conventional fluid profile logging for high-paraffin self-flowing oil wells at North China Oilfield. A fluid profile refers to the precise measurement of the proportions and flow rates of oil, water, and carbon dioxide produced from each perforated interval along the vertical depth of an oil and gas well. It enables identification of main producing zones, underutilized layers, gas-producing zones, and water-bearing zones, as well as assessment of CO₂ distribution, migration direction, and breakthrough locations within the wel

As of May 17, after applying CCUS-EOR (carbon dioxide capture, utilization and storage-enhanced oil recovery) technology in the Niuquanhu East area of Santanghu Oilfield, Turpan-Hami Oilfield has achieved cumulative oil production increase exceeding 20,000 tons in the pilot block, with a recovery factor improved by 1.4%, effectively doubling production in the test area. Turpan-Hami Oilfield features diverse and complex reservoir types. As development progresses, conventional reservoirs in mature areas exhibit high water content, while new areas primarily rely on unconventional production, leading to rapid production decline. Therefore, effective methods for enhancing recovery are urgently needed. After years of research and breakthroughs, the oilfield has successively ove

Since the beginning of this year, East China Chemical Sales has been steadily advancing its marketing breakthrough initiative amid a complex and ever-changing market environment.

As of May 25, Bayan Oilfield in North China Oilfield has achieved a cumulative crude oil production of nearly 700,000 tons this year, with a daily output reaching 4,800 tons—an increase of 20% year-on-year. This accounts for 30% of the total daily crude oil production of North China Oilfield, and the SEC reserve-to-production ratio remains stable and favorable, achieving simultaneous growth in both volume and efficiency. Since the beginning of this year, Bayan Oilfield has adhered to the principle of "identifying reserves with production potential, building productive capacity, and securing profitable output." Relying on integrated evaluation involving exploration and development, geological engineering, and technical economics, the field has prioritized high-return blo

On May 18, construction workers were carrying out orderly operations at the site of Lanzhou Petrochemical's new 110 tons/hour sour water stripping unit project.   For a long time, Lanzhou Petrochemical’s existing two sour water stripping units have had to operate at 120% capacity just to barely maintain a "tense balance" in handling sour water from the refining area. Project manager Gao Yunpeng said that with increasingly stringent national environmental regulations and the implementation of new facility plans, total sour water volume is expected to exceed 370 tons per hour, making current processing capacity insufficient to support production optimization and future development.   Once completed, the new unit will increase total sour water t

On May 11, it was learned from the Tarim Oilfield that the Keshen 41 well was officially put into production, with 300,000 cubic meters of natural gas produced daily and fed into the West-East Gas Pipeline. The well has a total depth of 8,473 meters upon completion, setting new records for the deepest burial depth and the highest oil pressure in the Kela Su salt-bearing gas reservoir. This adds another "deep well warrior" to the main gas source area of the West-East Gas Pipeline. The Keshen 41 well is located in Baicheng County, Xinjiang. It is a key pre-exploration well aimed at the ultra-deep layer and the search for replacement resources in the main gas supply area of the West-East Gas Pipeline by the Tarim Oilfield. The well encountered good oil and gas indications in

On May 5th, it was learned from Jilin Oilfield that the high-temperature resistant and high-strength water-absorbing swelling particle plugging agent developed by the Oil and Gas Technology Research Institute of the oilfield completed its first pilot test in the Yitong 45-2-6 well group. The test block showed a favorable development trend with a decline in liquid production, an increase in oil production, and a reduction in water cut. The water channeling control effect was remarkable. At the beginning of this year, the high-temperature resistant and high-strength water-absorbing swelling particle plugging agent entered the field test stage. Laboratory data indicated that the plugging agent could stably maintain its performance for 14 months at a temperature of 95 degrees
