Victory experts discuss the major plan of the heavy oil cold production demonstration project

China Petroleum & Chemical News Network recently, the national key research and development program "Heavy Oil Chemical Composite Cold Recovery Basic Research and Industrial Demonstration" three different reservoir types of demonstration areas of heavy oil viscosity reduction composite flooding pilot test project team held a promotion meeting in Dongying, from Shengli More than 20 experts and leaders from Oilfield, Shengli Petroleum Engineering Technology Research Institute, Exploration and Development Research Institute and related development units attended the meeting
.

Since the project was launched last year, the three heavy oil viscosity-reducing composite flooding pilot tests in the Zhongerbeiguan 5 block, the Jin 8 sensitive block and the Chen 373 thin-layer horizontal well heavy oil block have all made some progress
.

The expert group reached the following conclusions: In terms of basic theoretical research, it is necessary to strengthen the description of the pore throat structure, and to reveal the effective rules from the aspects of improving crude oil seepage capacity and the mechanism of producing remaining oil; it is necessary to carry out personalized design according to reservoir characteristics, contradictions and needs.

It is understood that the ultimate goal of the research and development project is to form the key technology of heavy oil chemical composite cold recovery and flooding, build 2 industrial application demonstration areas, increase the recovery rate by more than 5 percentage points, and balance the oil price within US$50/barrel
