Abstract: In recent years,highly efficient development of gas condensate reservoir especially gas with oil ringhas became a key topic in domestic oil and gas field development. This article taking the offshore oil ring condensation gas reservoir as an example, we mainly used the reservoir numerical simulation technology to analysis its reasonable pattern well spacing, well type,reasonable horizontal length of horizontal well,the reasonable oil gas development procedure,the oil ring irrigation effect and the effect of condensation gas reservoir circu- lation gas injection. The obtained conclusion laid a foundation for making reasonable development project of this condensate gas reservoir, and also provided a certain reference value for development similar to the condensate gas reservoir with oil ring.
