China’s largest ultra-deep condensate gas field—the Bozi-Dabei gas field operated by PetroChina’s Tarim Oilfield—has exceeded an annual natural gas output of 10 billion cubic meters, while also producing 918,900 metric tons of condensate oil.
The Bozi-Dabei Gas Field is located at the southern foot of the Tianshan Mountains and the northern edge of the Tarim Basin in Xinjiang. Following the Kela-Keshen trillion-cubic-meter gas field, it is another trillion-cubic-meter-level gas field discovered by the Tarim Oilfield in ultra-deep formations. It also serves as one of the main supply sources for the West-to-East Gas Pipeline and the South Xinjiang Gas Pipeline Network for Civilian Use. Unlike most medium-shallow, normally pressured oil and gas reservoirs worldwide, which are buried at depths of 1,500 to 4,000 meters, this gas field is generally located 6,000 to 8,000 meters underground, with an extremely complex geological structure. Characterized by ultra-deep, ultra-high temperature, ultra-high pressure, low porosity, and low permeability, its exploration and development challenges are considered rare worldwide and unique in China.
Facing these challenges, Tarim Oilfield innovated reservoir stimulation techniques, enabling the cost-effective and large-scale development of ultra-deep, complex condensate gas fields. The average daily gas production per well has reached 280,000 cubic meters. Based on the calculation that a three-person household consumes about 0.5 cubic meters of natural gas per day, the daily output of a single well here can meet the daily gas demand of 1.68 million people.
Since the start of the 14th Five-Year Plan period, Tarim Oilfield has accelerated the ramp-up of condensate oil and gas production by launching the Bozi-Dabei 10-billion-cubic-meter production capacity construction project. A total of 85 new wells have been drilled, and a surface backbone infrastructure system—primarily consisting of a natural gas processing plant, a condensate oil stabilization facility, and oil and gas transmission pipelines—has been built. These efforts have increased the annual natural gas processing capacity of the gas field from 5 billion cubic meters to 12 billion cubic meters.
The extraction of oil and natural gas cannot be achieved without separation equipment.
Our product — Desanding of produced condensate in Gas field is highly suitable for condensate gas fields.
The cyclonic desanding separator is a liquid-solid separation equipment. It uses the cyclone principle to separate solids, including sediment, rock debris, metal chips, scale, and product crystals, from fluids (liquids, gases, or gases-liquid mixture). It is used for removing those very fine particles (5 microns @98%) from the condensate which is separated from gas-liquid separator in which those solids went to the liquid phase and caused the blockage and erosion in the production system. Combined with SJPEE’s unique patented technologies, the filter element is made of high-tech ceramic wear-resistant (or called highly anti-erosion) materials or polymer wear-resistant materials or metal materials. High-efficiency solid particle separation or classification equipment can be designed and manufactured according to different working conditions, different fields and user requirements.
Proven in major global fields operated by CNOOC, CNPC, Petronas, and others across Southeast Asia, SJPEE desanders are deployed on wellhead and production platforms. They provide reliable solids removal from gas, well fluids, and condensate, and are critical for seawater purification, production stream protection, and water injection/flooding programs.
Beyond desanders, SJPEE offers a portfolio of acclaimed separation technologies. Our product line includes membrane systems for natural gas CO₂ removal, deoiling hydrocyclones, high-performance compact flotation units (CFUs), and multi-chamber hydrocyclones, delivering comprehensive solutions for the industry’s toughest challenges.
