Composite Evaluation Of Petroleum Trap Of Huan23 Area, Western Sag, Liaohe Basin

This article is directed by the conformation-geology, petroleum-geology, formality stratum, logging and sedimental theory .It uses many research methods such as geology digging, Logging and production data to evaluate the Huan-23 oil trap of the west Sag in Liaohe. It also researched the formation, sediment, production-zone of Huan-23.It provides the well-location after the comprehensive trap evaluation. It offers credibility geology proof for the exploration and development of LiaoHe.The main research results is:1. Cross section explain in detail carry out the boundary of some oil zones.2. After analysis for the sediment, it researches the character of the Huan-23 well-zones, and it also discovers that the fan-delta distributary, channel is the best production zones.3. It uses wave-inversion to predict. The sandstone distributing, and provides credibility proof for the trap evaluation.4. There are many kinds of reservoirs in this well-zones, mainly includes: formation oil gas reservoir, formation-lithology reservoir. Lithology reservoir, and buried-hill reservoir.5. Through the comprehensive evaluation to the Huan-23 trap. It newly recovers and carries out 12 avail trap, avail trap area 8.9km2, trap quantity is 2880X104t, in them, it has 8 trap I, the area is 6.6km2, to deploy 3 well.
