摘要
上市储量是油气公司的重要资产,而对于新投产区块,资产价值评估也较为重要。A区块是我国重要的致密气产区,在投产初期,在产井较少,上市储量评估存在较大难度。本文基于A区块及其邻区B区块地质特征、储层特征相近、可类比的前提,采用动态类比法,评估投产初期A区块上市储量。A区块在产井单井技术可采储量为850×10^(4)m^(3),总体单井技术可采储量700×10^(4)m^(3),与实际生产情况较为吻合。该方法将指导未来中海油新投产致密气区块上市储量评估,并对行业带来一定思考。
SEC reserves are important assets for oil and gas companies,and the assessment of asset value is also important for new production blocks.Block A is an important tight gas-producing area in China.In the initial production stage,there are few producing wells,making it difficult to assess the technically recoverable reserves.Based on the premise that the geological characteristics and reservoir characteristics of Block A and its adjacent Block B are similar and comparable,this paper adopts the dynamic analogy method to evaluate the SEC reserves of Block A in the initial stage of production.The technical recovera-ble reserves of the production wells in Block A are 850×10^(4)m^(3)per well,with a total technical recovera-ble reserves of 700×10^(4)m^(3)per well,which is consistent with the actual production situation.This meth-od will guide the evaluation of SEC reserves of CNOOC's new production tight gas blocks in the future,and provide insights for the industry.
