The old sand production blocks are activated by side drilling in Dagang oil recovery three plant
China Petroleum Network News Dagang Oilfield three oil plant vigorously promote scientific and technological innovation, sand disaster control achieved initial success. As of November 5th, 6 wells were applied in the 195 block of the serious sand producing area, and the production of blocks increased from 125 tons to 135 tons.
In block 195, the rapid accumulation of near source rocks is low in maturity and loose in cementation, and most of them are contact or contact pore cementation. Sand production is serious during water injection development, which affects the normal production of oil wells. At the beginning of this year, the three oil production plant took the shallow sidetrack drilling as an important way to produce stable production, and Guan 195 block was the first test area.
The study of residual oil reservoir depth expansion technology, analysis the production situation and sand production factors, establishing elastic modulus of the rock combination application of sonic velocity and density logging data, draw out the sand well risk zoning, do targeted lateral drilling.
Through the establishment of long-term mechanism of the normal production of oil wells, water injection intensity and injection production ratio optimization, keep the reservoir pressure and appropriate exploitation intensity, to minimize the probability of lateral drilling sand, achieve a virtuous cycle of oil production, improve the overall water flooding reservoir.
