Full investigation and analysis on the basis of our company in a high-pressure filling sand control technology based on research and development of the second sand control tool, combined with a high pressure sand tools, forming a fixed column secondary sand. : Before the sand down into the sand control string with the second filling tool, high pressure filling after the injection of steam wells producing 1-2 cycles, into the second filling the server through the backward slide and limit to open the second pack sand control tool, circulatory filling or high-voltage secondary filling the oil casing annulus, the second sand construction of the fixed column.
Through the construction of secondary sand, you can make the annulus deficit filling sand to be replenished in a timely manner to reduce the formation sand into the annulus the impact of the sand system, extending the validity period of the sand. Also available through the high pressure pack sand near wellbore second transformation to reach the purpose of the secondary yield fixed column. And shorten the cycle time and operating cost inputs.
