Recently, the Dongxin operation area of the Shengli Oilfield Downhole Operation Center implemented sand control modification to the Yong 68 Incline 13 Well.
The daily oil production increased from 0.
4 tons to the current 8.
3 tons, which achieved a good increase in production
.
The production horizon of Well Yong 68 Incline 13 is Sha 2 6(1), the oil layer depth is 1518-1522.
5m, the effective perforation thickness is 4.
5m, the average permeability is 2292md, the shale content is 7.
3%, and the reservoir physical properties are good
.
The well was operated due to insufficient fluid supply.
Due to the high water cut, the well has been blocked by blasthole construction in the Sha 2 5 (1) well section 1508.
1-1510.
1 meters and Sha 2 6 (2) well section 1530-1531 meters
.
The risk of conventional high-pressure gravel packing is high and the success rate is low .
The construction staff actively changed their concepts and refined the sand control plan
.
The use of pressure-limiting, small-displacement and high-pressure gravel filling does not break through the high-pressure water layer near the production zone, but can break through the pollution zone near the production zone, thereby greatly reducing flow resistance and increasing oil well productivity.
In order to ensure the successful implementation of the sand control technology of the well, technicians tracked, monitored and guided the construction throughout the process
.
Through analysis of measures, refinement of the plan and on-site supervision, the sand control quality of the well has been improved and the sand control effect has been ensured
The success of the well has benefited from the active innovation of the construction staff and optimization of the operation technology
.
In the next step, construction personnel will continue to strengthen technology promotion in similar reservoirs to provide strong support for improving the quality and efficiency of low-efficiency wells
