| The technology can quantitatively test production, moisture, static pressure, flow pressure, skin factor, temperature and other data of all wells to provide a basis for stratified reasonable recovery and making stable oil-water control measures.The technology uses sophisticated top anti-anti-channeling balance lost hand columns .And it can make the entire reservoir divided into 2-5 paragraphs, instrument gone into delay state by monitor smart sensor packer to release the pressure. When the delay to the scheduled time, the control circuit in the lowest monitor instruct electrical work , drive the upper and lower plunger to open for liquid into and out of hole.others monitor remain closed . At this time do pumping liquid production with the situation in accordance. Single-layer gauge flow pressure can be measured in the production process, and in the ground single-output can be measured by level recovery . After closing the low block 30 minutes, up levels are opened, in all respective levels , achieve the data of the production, moisture, static pressure, flow pressure, skin factor, temperature and others .In the old block, Stratified test and production allocation wells total nine wells, the average increase oil in single-well is 0.54t/d, precipitation is 18.21m3/d. there is a hierarchical test well. Combining with new single-pressure injection wells and Arai shot the whole sub-fracturing can sure the main production layer of fuyu oil field , Statistics show 40 major reservoir fracturing wells in Putaohua 333-462-463 wells. Comparing to 3 the pre-full-well fracturing wells, yield remained basically unchanged, the reduced number of pressure cracks 2.5, the reduced single well fracturing cost is 238,000 yuan. |
