In areas including Penglai, Fuman, Shunbei,etc., Shenkai workers are making contribution to China’s petroleum industry against the scorching heat and cold.

Introduction to the Solutions for Deep-earth Engineering

• Solutions for ultra high pressure and high temperature well control

China’s onshore deep and ultra-deep wells are featured with complex geological conditions, high drilling safety risks, and long drilling cycles. In particular, ultra-high temperature, ultra-high pressure, multi-pressure system, hard formation, poor drillability, rich acid fluid and other problems coexist in Tarim Basin and Sichuan Basin. Safe, high-quality and efficient drilling is extremely challenging in the face of a series of world-class technical problems for deep well and ultra-deep well drilling and completion.

As a leading manufacturer of BOPs, control systems, and manifold systems in China, Shenkai can provide ultra-high pressure and high-temperature well control solutions for ultra-deep drilling.

· ltra-high pressure BOP stack and manifold system (140MPa)

· High temperature resistant ram rubber core (max. limit temperature 177 ℃)

· Intelligent and refined control system (electronic control type)

· Integrated wellbore liquid level monitoring system (timely detection and alarm of well leakage and overflow)

• Ultra high pressure intelligent wellhead solutions

With the continuous breakthrough and success of deep and ultra-deep wells, there is an increasing demand for pressure resistance of wellhead equipment. The high pressure of over 20000 psi in 10000m deep wells poses severe challenges to the sealing structure design, processing technology, material selection,etc. of wellhead equipment.

Shenkai has profound technical reserves in wellhead equipment and has taken the lead in developing HH level Christmas trees in China. Currently, in the application of deep and ultra-deep wells, the R&D and design of ultra-high pressure valves and Christmas trees, etc. have been completed, and fast, safe, and efficient intelligent management can be achieved together with the intelligent wellhead system.

· Ultra-high pressure, ultra load-bearing capacity wellhead and Christmas tree (175/210MPa)

· Ultra-high pressure valve series (175/210MPa)

· Intelligent wellhead control system

• Solutions for ultra-high temperature and ultra-high pressure cable logging and LWD
  

Generally, there are difficulties in the exploration and development of deep and ultra-deep wells including ultra-high temperature and ultra-high pressure, and the downhole instruments has high requirements for temperature and pressure resistance; downhole instruments and tools are subjected to high vibration conditions far exceeding industry standards, which results in a significant increase in failure rate; due to the limitations of sealing design, some downhole instruments are facing severe challenges from high sulfur well conditions in the Southwest region.

With brilliant achievements in both in cable logging and LWD, Shenkai has overcome a series of difficulties such as high temperature resistance, high vibration resistance, high pressure resistance, and hydrogen sulfide resistance of downhole instruments, and provided high-quality downhole instruments  and engineering technical services for major oil fields.
