Research on numerical simulation of block WEN-8 condensate gas reservoir development

The Block Wen-8 oil and gas reservoir is located in the vicinity of the Qiketai Town, Shanshan County, Tulufan Prefecture, the Xinjiang Uyghur Autonomous Region, being near to the Wenjisang oil field and Mideng oil field and belonging to the Wenjisang structural belt. The oil and gas reservoir is a condensate gas reservoir with a oil ring. Since the well W8-45's being put into production test in August 1993, there had been an oil-ring development history of about 4 years by the end of December 1996. Because the Shan-Wu gas transportation engineering will be put into operation, the Block Wen-8 condensate gas reservoir development has become a focal point of the research work. In the paper, on the basis of fully studying the geological and development characteristics of the Block Wen-8 oil and gas reservoir of Tu-Ha Oil Field, the effects of these factors as recovery method, development layer series, well pattern, wellhead pressure, gas production rate, planning and proration, etc., on the development effectiveness are simulatively calculated by use of a full component model; through the correlation and analysis of various technical criteria, an operated plan is optimized; and in coordination with Qiudong condensate gas field, the bases are provided for the surface NGL recovery and surface development engineering construction of condensate gas in Tu-Ha region.
