[Abstract]:Based on the analysis and summary of horizontal wells in Xiliukou area of Lixian slope in Raoyang depression, the reservoir geological characteristics suitable for horizontal well development are obtained, and the rational well pattern and water injection policy are discussed. To formulate the standard and method of horizontal well design and optimize the technical policy of horizontal well development. The main contents of this study are as follows: first, evaluation of geological applicability of horizontal wells, including geological evaluation of horizontal wells, The design standards and methods of horizontal wells and the geological characteristics of the blocks suitable for the deployment of horizontal wells in Xiliu, the applicability evaluation of reservoir engineering, including well pattern, water injection policy and economic benefit evaluation, and the optimization of horizontal well development technology policy, The research includes well type, well spacing, horizontal section length, fracturing fracture optimization and so on. Fourth, oil recovery technology research, including completion, perforation, oil production and evaluation of stimulation measures. By adopting the appropriate technical route, that is, through the analysis of the actual drilling horizontal wells in Xiliu Tongkou area, the reservoir geological characteristics suitable for horizontal well development are summarized, and the design method of horizontal wells in Xiliu Tongkou area is summarized, which is optimized. The standard of horizontal well design is formulated. Through the study of real drilling horizontal well, the applicability and economic evaluation of well pattern and water injection policy of horizontal well are analyzed. On the basis of the application of horizontal well, the specific development technology is optimized. The optimum selection of appropriate oil production technology. Through the study, five points of understanding are obtained: first, reservoirs with simple structure, stable distribution of sand bodies and less vertical upper layers of oil layers have geological conditions for drilling horizontal wells; second, from the point of view of the production effect of the horizontal well areas that have been drilled, For reservoirs with good reservoir physical properties, most wells are at the edge of benefit in drilling horizontal wells. For reservoirs with poor physical properties and poor oil quality, most wells are on the edge of benefits; third, for low permeability reservoirs, water must be injected ahead of time, and for conventional permeable reservoirs, The requirements of water injection timing are not high; fourth, casing cementing completion, segmental perforation, conventional production process is more appropriate; fifth, acidification and fracturing are effective means to increase production in horizontal wells.
