Grape Flower Oil Layer Horizontal Well Development Effect Research

Since the periphery "three has been low" the oil deposit effective development is the Daqing Oil Field "95" one of key attack topics. At present eight factories areas have not used the reserves for 19510×104t, in which holds the Yang oil layer for 11485×104t, the grape flower oil layer for 8025×104t, separately occupies eight factories areas not to always use the geological reserve 58.9% and 41.1%. This part of reserves abundance low, the permeability bad, under the existing development engineering factor uses the difficulty to be bigger. In view of the above question, first take the grape flower oil layer as the breach, has carried out the horizontal well development experimental study, in 2002 has successively completed 14 horizontal wells development experiments, "three will be low" the oil field next large-scale horizontal well development for the Daqing periphery and has not used the reserves effective use to accumulate the precious experience and the technology.This article main research:In the horizontal well design process, uses the seismic interpretation, the geological modelling, the value simulation, the economic evaluation and so on the multi-disciplinary research technique, clarified has drawn up the cloth horizontal well area reservoir characteristic, optimized the well position design, had forecast the horizontal well produced can, the development effect and the benefit condition; In the well drilling process, uses the LWD monitoring meter, the sample log and so on the many kinds of technical method real-time monitoring, causes the horizontal well to go through in the 2m thin layer, and the success passed through Minor fault, has realized two landings; After two wells went into production have obtained a better effect, at present picks by 1.0 notes compares the production, and has done the value simulator study work, studies the present horizontal well further to reduce the investment the feasibility. Also has carried on the proof to the horizontal well development feasibility.This article has also conducted the research to the horizontal well necessary craft Relay pumped Lifting the craft to satisfy well in 60 within oil pumping Lifting request; The horizontal well acidification continual drill tubing acidification craft can effectively relieve the well drilling, the well completion stage to the stratum pollution, is effective action which the realization horizontal well increases production, has obtained a better effect.
