| Product Name: | DS-1 self-producing CO2 compound stimulation technique |
| Product introduction: |
1、Technology introduction
CO2 has the effect of reducing crude oil viscosity, supplementing formation energy and lowering tension. CO2 is an ideal injection gas to improve the effect of steam stimulation. However, conventional liquid CO2 has problems such as gas source, transport, corrosion, safety and environment.
DS-1 self-producing CO2 compound stimulation technique screens self-producing CO2 system, optimizes the effective surfactant, and combines the two on the basis of reaction speed and economic factor. In addition to the basic mechanism of CO2 stimulation technology, this technology has a unique action mechanism, which is a very promising technology.
2、Field application
DS-1 self - generated CO2 initiator agent and foam auxiliary steam injection technology test was implemented on 8 wells in 2007, one of the oilfields is” C20-8-8 Cao 20 block” Le’an oilfiled of Shengli Oilfield. After implementation, the test effect is good, periodical oil production increase 3765t, average single well periodical oil production increase 470t. After 2008, this technique was implemented in large scale, average single well periodical oil production increase 300t
